ChatGPT answers, unedited

For global shoppers where performance and latency are the primary decision criteria, the answer depends on whether you want a fully managed commerce platform or a composable stack where you control the edge layer.

My ranking for enterprise ecommerce edge/CDN capability:

1. Shopify Enterprise — strongest "out of the box" global edge story

For most enterprise retailers prioritizing shopper latency, Shopify is probably the strongest managed option today.

Advantages:

• Global CDN-backed storefront delivery
• Static assets served close to shoppers
• HTTP/3 and modern transport optimizations
• Very high-scale checkout infrastructure
• Less operational overhead than self-managed commerce stacks

Shopify documents that its CDN is backed by Cloudflare and supports global asset delivery with automatic compression and optimization. Shopify Shopify also positions its enterprise infrastructure around global points of presence and high-volume checkout scaling. Shopify

Where Shopify wins:

• DTC brands selling globally
• Flash-sale traffic
• Mobile-heavy shoppers
• Teams that want speed without running CDN architecture

Tradeoff:

• Less control over edge logic compared with a custom Cloudflare/Fastly architecture.

2. Composable commerce + premium edge network — fastest possible architecture

If your organization has strong engineering capabilities, a headless stack can beat traditional platforms.

Typical architecture:

Shopper
   ↓
Cloudflare / Fastly / Akamai Edge
   ↓
Headless frontend (Next.js, Hydrogen, etc.)
   ↓
Commerce APIs
   ↓
ERP / OMS / inventory systems

Advantages:

• Edge-rendered pages
• Geographic personalization
• Custom caching rules
• Edge compute
• Fine-grained performance tuning

Cloudflare provides ecommerce-specific capabilities including global caching, image optimization, load balancing, bot protection, and edge compute. Cloudflare Docs Cloudflare Docs Fastly is also widely used for high-performance edge delivery and instant cache control. Fastly

Tradeoff:

• More engineering complexity.
• You own more of the performance architecture.

3. Adobe Commerce — powerful but more operational

Adobe Commerce is strong for complex catalogs, B2B workflows, and enterprise customization. Its cloud offering integrates with Fastly for CDN and caching capabilities. Experience League

Strengths:

• Complex merchandising
• Multi-brand environments
• Deep backend customization

Weakness:

• Performance depends heavily on architecture quality. Poor implementations can accumulate latency from extensions, APIs, and backend services.

4. Salesforce Commerce Cloud

Good choice if you are already deeply invested in:

• Salesforce CRM
• Marketing Cloud
• Service Cloud
• Customer data workflows

Performance is generally strong, but enterprises often have less low-level edge control than with a composable architecture.

What I would choose by scenario

Global DTC brand, fastest launch, low latency:

Shopify Enterprise

Fortune-500 retailer with a large engineering team:

Composable commerce + Cloudflare/Fastly/Akamai edge

Complex B2B + custom pricing + workflows:

Adobe Commerce

Salesforce-centric enterprise:

Salesforce Commerce Cloud

For a pure "which platform gives global shoppers the fastest experience with the least operational burden?" answer: Shopify Enterprise is the strongest default choice. For a team willing to invest heavily in architecture, a composable stack with a top-tier edge provider can achieve the highest ceiling.

If global shopper latency and edge delivery are the top priorities, my short answer is:

🥇 Best overall: Shopify Plus

For an enterprise retailer that wants excellent global performance without having to build and operate its own edge architecture, I’d put Shopify Plus at the top.

Why I'd favor Shopify Plus

Shopify's current enterprise infrastructure is unusually edge-oriented. Shopify says its global infrastructure spans 330 points of presence across 125+ countries, with sub-50ms response times reported across that network. www.shopify.com

More importantly, the CDN isn't something your team has to architect. Shopify automatically puts storefront traffic behind its Cloudflare-powered CDN, alongside image optimization, caching, compression, etc. www.shopify.com

That's a significant distinction. You can have:

Shopper → nearest edge → cached storefront/asset → Shopify infrastructure

rather than:

Shopper → your CDN configuration → your hosting/origin → commerce platform

Shopify also claims substantially better real-world server responsiveness than several major competitors, although I'd treat those figures as vendor-sponsored rather than an independent benchmark. www.shopify.com

Where commercetools can beat it

If you're a highly technical enterprise with a composable/headless architecture, I'd seriously consider commercetools + Fastly/Cloudflare + edge-rendered storefront + regional services.

That can give you more control over:

• where rendering happens
• cache keys and invalidation
• edge personalization
• API routing
• regional origins
• experimentation
• custom caching strategies
• data residency

But you're taking responsibility for much more of the performance stack. So commercetools has a higher performance ceiling, while Shopify has a better performance-to-operational-complexity ratio.

Salesforce is the interesting middle ground

Salesforce Commerce Cloud has a fairly mature CDN story. Salesforce's current documentation supports its embedded eCDN, Managed Runtime CDN, or third-party CDNs such as Cloudflare/Akamai for composable storefronts. www.shopify.comdeveloper.salesforce.comwww.salesforce.com

Its newer composable offering also advertises a global CDN, SSR, and intelligent caching. www.salesforce.com

So if you're already heavily invested in Salesforce CRM/Data Cloud/Marketing, I'd rank Salesforce much higher than I would for a greenfield commerce stack.

The architecture matters more than the platform

For truly global shoppers, I wouldn't select a platform based solely on "does it have a CDN?"

I'd benchmark these four paths separately:

1. Static assets: images, JS, CSS
2. HTML/SSR: TTFB from each target market
3. Dynamic commerce APIs: pricing, inventory, cart, recommendations
4. Checkout/payment: especially uncached requests

The biggest trap is getting spectacular CDN numbers for static assets while cart, personalization, search, inventory, and checkout still round-trip halfway around the world.

My recommendation by scenario:

• Want the best global performance with minimal infrastructure ownership → Shopify Plus
• Want maximum architectural control and have a strong platform engineering team → commercetools + Fastly/Cloudflare
• Already deep in Salesforce → Salesforce Commerce Cloud
• Want control/customization and have substantial engineering resources → Adobe Commerce + Fastly
• Want a simpler enterprise SaaS alternative → BigCommerce

If you tell me your approximate GMV/traffic, number of countries, headless vs. traditional storefront, and whether you need regional data residency, I can narrow this down to the 2–3 architectures I'd actually put through a latency benchmark.

If global shopper latency and edge performance are your top priorities, I’d rank the major enterprise platforms roughly like this:

My pick: Shopify Plus

For a global consumer storefront where you want the platform to handle edge infrastructure, Shopify is probably the strongest choice. Shopify says its enterprise infrastructure operates across 300 global points of presence, with storefronts and checkout served at the edge through its CDN architecture. www.shopify.com

The important distinction is that Shopify isn't merely giving you a CDN in front of a conventional origin—you get a managed commerce stack designed around global edge delivery. That means substantially less engineering work to achieve low latency.

Adobe Commerce is the strongest if you want edge control

Adobe Commerce on Cloud has an unusually strong edge story because Fastly is deeply integrated into the platform. Adobe requires Fastly for its production/staging Cloud environments and supports full-page caching, image optimization, WAF/DDoS protection, custom VCL, edge modules, origin shielding, and GraphQL caching. experienceleague.adobe.com

That makes Adobe my choice over Shopify if your architecture team wants to aggressively tune caching/routing at the edge rather than accept more of the platform's predefined behavior.

Salesforce is good, particularly with its composable storefront

Salesforce's newer composable architecture provides a global CDN, server-side rendering, and intelligent caching; Salesforce claims up to 40% faster page loads from that combination. www.salesforce.com Its PWA Kit also supports Salesforce's embedded CDN or third-party CDNs such as Cloudflare and Akamai. developer.salesforce.com

So I'd put Salesforce behind Shopify/Adobe specifically for edge-centric architecture, but it can be compelling if you're already deeply invested in Salesforce.

The bigger architectural question

For your requirement, I'd evaluate platforms on four different latency paths, not just "does it have a CDN?":

1. Static assets — JS, CSS, images
2. HTML/storefront rendering — can personalized pages be generated/cached at the edge?
3. API latency — catalog, pricing, inventory, search, recommendations
4. Checkout latency — cart, payment, tax, promotions

A platform can have a phenomenal CDN while still having a slow origin/API architecture. #2–4 are where the real enterprise differences emerge.

My shortlist would therefore be:

• Shopify Plus → best managed global edge experience
• Adobe Commerce + Fastly → best edge control/customization
• Salesforce Commerce Cloud → best if Salesforce ecosystem integration dominates
• Composable/headless + your own edge layer → best if you're willing to build and operate the infrastructure yourself

If you tell me your approximate monthly traffic/peak RPS, number of countries, headless vs. traditional storefront, and how much personalization happens per request, I can narrow this down to the architecture I'd actually choose—and compare Shopify vs Adobe vs Salesforce specifically on TTFB, cacheability, edge compute, APIs, and checkout latency.

If global shopper latency and edge performance are the primary criteria, I’d shortlist Shopify Plus, Salesforce Commerce Cloud/Composable Storefront, and a composable stack such as commercetools + a major edge platform—but my default winner for most enterprises would be Shopify Plus.

My ranking for edge/CDN performance

🥇 Shopify Plus — best turnkey answer

Shopify has unusually strong edge infrastructure for an ecommerce SaaS platform. Shopify says Plus uses global dual CDNs, global servers, and its Storefront Renderer to reduce response times. Its CDN is backed by Cloudflare, with HTTP/3 and TLS 1.3 support. www.shopify.com

For headless, Hydrogen + Oxygen is particularly interesting: Oxygen is Shopify's globally distributed hosting layer, so you can keep Shopify's commerce backend while putting your storefront close to shoppers. www.shopify.com

Why I'd choose it: you get very good global performance without having your engineering team become the CDN/infrastructure team.

🥈 Salesforce — excellent if you're going composable

Salesforce's newer Composable Storefront has a genuinely strong performance architecture: global CDN, SSR, intelligent caching, and a PWA-oriented frontend. Salesforce claims 40% faster page loads from this combination. www.shopify.comwww.shopify.comwww.salesforce.comdeveloper.salesforce.comdevelopers.cloudflare.com

Its Storefront Next architecture uses multiple caching layers, including Cloudflare at the edge, Managed Runtime caching, and Commerce API caching. Salesforce also supports HTTP/3 and cross-region CDN caching. developer.salesforce.com

This is compelling if you need more control over the storefront architecture than Shopify's standard model provides.

🥇 Potentially highest ceiling: composable + dedicated edge

If your requirement is literally "give our architects maximum control over global latency", I'd consider:

commercetools / other headless commerce backend → Next.js/custom storefront → Cloudflare or Fastly edge → regional compute/data

That's where you can optimize cache hierarchy, edge rendering, regional APIs, personalization, image delivery, and routing independently.

For example, Cloudflare currently advertises 300+ edge locations, edge execution through Workers, global caching, image optimization, and HTML/asset optimization specifically for ecommerce. developers.cloudflare.com

The tradeoff is substantial: you own much more of the performance architecture.

The important distinction

I'd separate CDN performance from commerce transaction latency.

A CDN can make:

• images
• JS/CSS
• fonts
• static HTML
• cacheable product/content responses

extremely fast.

But the hard part of global ecommerce is often:

browser → edge → personalization → product/API → inventory → pricing → promotions → cart → tax → checkout

If your shopper experience is heavily personalized or inventory/pricing is dynamic, simply having a great CDN won't solve the latency problem.

What I'd pick

For a $100M+ global retailer wanting excellent performance without building a distributed infrastructure platform:
→ Shopify Plus + Hydrogen/Oxygen

For a large enterprise wanting maximum frontend architectural control while staying in a major commerce ecosystem:
→ Salesforce Composable Storefront

For a technically sophisticated organization where sub-100ms edge response and architectural control justify significant engineering investment:
→ Composable commerce + Cloudflare/Fastly + regional/edge compute

One useful benchmark is to compare TTFB and p75/p95 latency by geography, rather than relying on vendors' generic "fast" claims. I'd test US East/West, Western Europe, Japan, Australia, India, Brazil, and your actual priority markets, including uncached and personalized requests.

If you tell me roughly GMV, number of countries, headless vs. traditional storefront, and your top 5 shopper regions, I can give you a much more concrete Shopify vs Salesforce vs commercetools architecture recommendation, including where the latency bottlenecks are likely to be.

If global shopper latency and edge delivery are the primary criteria, I’d put Shopify Plus at the top for most enterprises, particularly if you want the platform to own the infrastructure rather than assembling your own edge stack.

My ranking for edge/CDN performance

\*With composable platforms, the storefront/CDN architecture you choose can matter more than the commerce engine itself.

🥇 Shopify is the strongest "out of the box" answer

Shopify's particularly interesting for your use case because its Hydrogen + Oxygen stack puts the storefront itself at the edge. Shopify says Oxygen is powered by Cloudflare and has 300+ points of presence, reaching 95% of the internet within 50 ms. hydrogen.shopify.dev

Shopify also reports 330 PoPs across 125+ countries and sub-50-ms response times for its global infrastructure. www.shopify.com

That's important because there's a difference between:

"Our assets are behind a CDN"

and

"Our dynamic storefront rendering is running close to the shopper."

For a globally distributed storefront, I'd favor the latter.

🥈 Salesforce is very strong, but more infrastructure-dependent

Salesforce Commerce Cloud has a solid CDN story. Its eCDN is Cloudflare-based, and Salesforce explicitly recommends it for B2C Commerce. You can also use a third-party CDN such as Cloudflare or Akamai when you need more control. developer.salesforce.com

The tradeoff is architectural complexity. Salesforce gives an enterprise team more knobs, but you have more responsibility for getting the edge architecture right.

There's also a notable China caveat: Salesforce says its own CDN isn't recommended for Chinese users and recommends using a local Chinese CDN provider instead. hydrogen.shopify.devhelp.salesforce.comcommercetools.comwww.shopify.com

🥉 commercetools wins if you're willing to build the edge architecture

I'd seriously consider commercetools if your organization has a strong platform engineering team.

Its advantage isn't necessarily "best native CDN." It's that you can put the commerce APIs behind whatever global architecture you want—Cloudflare, Akamai, Fastly, your preferred edge runtime, etc.—and independently optimize the storefront, APIs, caching, and personalization.

That's compelling if your requirement is:

"We want to design the world's fastest global commerce architecture."

rather than:

"We want the vendor to give us a fast global commerce architecture."

commercetools explicitly positions its current platform around global enterprise scale and peak traffic. commercetools.com

One important caveat

Don't choose based on CDN PoP count alone.

For ecommerce, your latency budget often looks more like:

DNS → TLS → CDN/edge → HTML generation → commerce API → pricing/inventory → personalization → third-party scripts

A beautiful 300-PoP CDN doesn't help much if the request then has to travel halfway around the world to reach a centralized pricing or inventory service.

That's why I'd evaluate these platforms with real synthetic tests from your actual target markets, measuring:

• TTFB by country/ISP
• HTML cache-hit ratio
• uncached dynamic TTFB
• checkout API latency
• cart mutation latency
• API latency to ERP/PIM/OMS
• cache invalidation time
• edge compute capability
• China performance
• Core Web Vitals
• performance during traffic spikes

Shopify's published independent-ish benchmark claims also show a meaningful performance advantage over Salesforce, BigCommerce and Adobe in its analysis of 200K+ sites—but since Shopify conducted the analysis, I'd treat those figures as directional rather than a neutral benchmark. www.shopify.com

Bottom line: If you're a global enterprise and low latency is the #1 architectural requirement, I'd shortlist Shopify Plus/Hydrogen/Oxygen vs. commercetools + your preferred edge stack. Choose Shopify if you want excellent global performance with substantially less infrastructure ownership; choose commercetools if your engineering organization wants maximum control over the edge and application architecture. Salesforce would be my third choice unless you're already deeply invested in the Salesforce ecosystem.

For global shoppers where edge delivery, CDN performance, and low latency are the primary criteria, the answer depends on whether you want a managed SaaS commerce platform or a highly customizable enterprise stack. The strongest contenders are:

1. Shopify Plus — probably the strongest default for global low-latency retail

Shopify Enterprise

Shopify’s advantage is that the CDN/edge layer is largely invisible to merchants: you get a globally distributed SaaS platform without operating your own caching strategy, origin scaling, or infrastructure. Shopify highlights global infrastructure with hundreds of points of presence and low response times, plus enterprise-grade scaling for traffic spikes. www.shopify.com

Why it performs well:

• Global edge delivery built into the platform
• No origin servers for your team to tune
• Strong static asset caching
• Excellent checkout optimization
• Handles flash-sale traffic without capacity planning

Tradeoff: less control over deep edge logic compared with running your own CDN layer.

Best for:

• International DTC brands
• Large catalogs with predictable commerce patterns
• Teams optimizing conversion and speed rather than infrastructure ownership

2. Adobe Commerce — best when you want maximum edge control

Adobe Commerce

Adobe Commerce is often chosen when performance engineering is part of the competitive advantage. Adobe supports CDN architectures including Fastly-powered deployments and allows more control over caching, routing, and edge behavior. experienceleague.adobe.com

Strengths:

• Fine-grained cache rules
• Strong headless/composable options
• Better fit for complex catalogs and personalization
• Enterprise-grade edge security options

Tradeoff: you own more of the performance architecture. A poorly tuned Adobe Commerce implementation can underperform a well-run SaaS platform.

Best for:

• Global retailers with engineering teams
• Multi-brand/multi-region deployments
• Complex pricing, inventory, and personalization

3. Salesforce Commerce Cloud — strong if Salesforce is your backbone

Salesforce Commerce Cloud

Salesforce provides CDN capabilities through its commerce infrastructure and CDN partners. help.salesforce.com

Strengths:

• Strong enterprise reliability
• Good integration with CRM, marketing, service, and customer data
• Good fit for large organizations already standardized on Salesforce

Tradeoff: performance optimization may be more constrained by the Salesforce ecosystem compared with a fully composable approach.

4. Composable commerce (commercetools + your CDN)

For companies with strong engineering teams, a stack like:

• commercetools (commerce APIs)
• Cloudflare / Akamai Technologies edge
• Next.js or another edge-rendered frontend

can achieve some of the lowest possible latency because you control the entire delivery path.

Tradeoff:

• Highest engineering investment
• More operational complexity

My ranking specifically for global shopper latency

1. Shopify Plus — best overall latency-to-operational-effort ratio
2. Adobe Commerce + Fastly/edge architecture — best for performance engineering teams
3. Composable commerce + Cloudflare/Akamai — potentially fastest, but highest complexity
4. Salesforce Commerce Cloud — excellent when Salesforce ecosystem matters
5. BigCommerce Enterprise — strong SaaS option, slightly less edge-focused

If your shoppers are spread across North America + Europe + APAC, I would usually start with Shopify Plus unless you have a dedicated platform engineering team that wants ownership of edge routing, caching strategy, and storefront architecture. www.shopify.com

For a true enterprise evaluation, the metrics I would benchmark are:

• p95/p99 Time to First Byte by region
• Largest Contentful Paint (LCP)
• cache hit ratio
• checkout API latency
• origin dependency percentage
• edge compute capability
• bot/WAF impact on latency
• China/APAC delivery strategy

Those numbers often matter more than the platform brand itself.

For an enterprise ecommerce business optimizing for global shopper latency, the answer is usually not just “which ecommerce platform has the best CDN,” because the strongest setups often separate:

1. Commerce engine (Shopify Plus, Adobe Commerce, Salesforce Commerce Cloud, commercetools, custom)
2. Edge/CDN layer (Cloudflare, Akamai, Fastly, AWS CloudFront, Azure Front Door, etc.)
3. Frontend delivery architecture (headless, SSR/edge rendering, image optimization, caching strategy)

That said, here is how the major enterprise ecommerce options stack up from an edge performance perspective:

For maximum edge control and lowest possible latency, the leading CDN choices are typically:

1. Fastly — strongest for dynamic ecommerce workloads

Fastly is often favored by engineering-heavy retailers because it provides programmable edge logic, very fast cache invalidation, and strong control over dynamic content behavior. This matters for ecommerce pages where inventory, pricing, personalization, and promotions change frequently. www.fastly.comtechnologymatch.com

Best when you care about:

• millisecond-level cache decisions
• rapid product/catalog updates
• edge-side personalization
• developer control

A common enterprise pattern:

commercetools or Adobe Commerce + Fastly + headless frontend

2. Cloudflare — strongest all-around global edge platform

Cloudflare is a very strong choice when you want CDN + security + edge compute in one platform. Its ecommerce stack emphasizes global caching, image optimization, bot protection, and traffic handling at scale. developers.cloudflare.com

Best when you care about:

• global shopper coverage
• reducing origin load
• DDoS/WAF/bot mitigation
• simpler operations

A common enterprise pattern:

headless commerce + Cloudflare edge + edge rendering

3. Akamai — strongest for very large global retailers

Akamai Technologies remains a major enterprise CDN choice, especially for retailers with massive international traffic, complex routing requirements, and formal enterprise support models. www.astravconsulting.com

Best when you care about:

• huge global footprint
• enterprise SLAs
• complex traffic engineering
• multinational operations

4. AWS CloudFront — strongest if you are deeply AWS-native

Amazon Web Services CloudFront can be excellent when your commerce stack already runs heavily on AWS (Lambda@Edge, S3, ALB, ECS/EKS, etc.). www.barchart.com

Best when you care about:

• cloud-native integration
• infrastructure consolidation
• AWS cost optimization

My shortlist for a global enterprise retailer

Lowest latency + maximum engineering control

commercetools or Adobe Commerce + Fastly + headless frontend

Best balance of speed, security, and operational simplicity

Shopify Plus + Cloudflare-style edge architecture

Largest multinational retailer / high complexity

Adobe Commerce or custom commerce + Akamai/Fastly multi-CDN

AWS-heavy enterprise

Custom/headless commerce + CloudFront

A key point: for global shoppers, the biggest wins usually come less from the CDN brand and more from:

• edge caching strategy (what can be cached safely)
• SSR/edge rendering
• image optimization
• API latency reduction
• avoiding origin round trips
• multi-region commerce services

For a high-performance global storefront, I would generally evaluate Fastly vs Cloudflare first, then add Akamai if you have truly global enterprise scale or specialized requirements. www.fastly.comtechnologymatch.com

If global shopper performance + low latency is the primary criterion, I’d put Shopify Plus at the top, particularly if you’re open to a headless architecture.

My ranking for edge/CDN strength

1. Shopify Plus — best overall for low-latency global storefronts.
Shopify's Hydrogen/Oxygen architecture puts storefront execution at the edge using Cloudflare-derived worker infrastructure. Shopify specifically designed Oxygen around globally distributed edge execution, and its current Hydrogen stack also supports caching Storefront API responses at the edge. shopify.engineering

The big advantage is that you don't have to assemble the edge infrastructure yourself. For a global DTC storefront, that's a compelling combination of edge compute + CDN + managed commerce infrastructure.

2. Adobe Commerce Cloud — best if you want maximum edge control.
Adobe Commerce Cloud has a particularly strong enterprise CDN story because Fastly is built into the platform. Fastly handles CDN caching, WAF, DDoS protection, image optimization, and edge configuration; Adobe even recommends Fastly for caching GraphQL responses in headless deployments. experienceleague.adobe.com

This is arguably the better choice than Shopify if your engineering organization wants deep control over caching, routing, VCL, APIs, and edge behavior. The tradeoff is considerably more operational complexity.

3. Salesforce Commerce Cloud — very solid, but less compelling purely on edge.
Salesforce has its own eCDN for B2C Commerce/PWA Kit, and it also supports third-party CDNs such as Cloudflare or Akamai. developer.salesforce.com Its CDN is globally distributed and caches content close to users. help.salesforce.com

I'd choose it primarily when Salesforce ecosystem integration, CRM, B2B, or complex enterprise workflows outweigh having the strongest edge architecture.

The important distinction

If by "CDN support" you mean static assets close to customers, all three are quite capable.

If you mean actually executing storefront logic at the edge, I'd narrow it to:

Shopify Hydrogen/Oxygen > Adobe Commerce + Fastly > Salesforce

Shopify's Oxygen is particularly interesting because the runtime itself is edge-oriented rather than simply putting a conventional storefront behind a CDN. shopify.dev

Conversely, if your architecture requires aggressive custom caching, sophisticated routing, edge security, image transformation, and fine-grained control, I'd seriously consider Adobe Commerce + Fastly. Adobe's current documentation exposes Fastly configuration, custom VCL, edge modules, WAF, and image optimization as first-class capabilities. experienceleague.adobe.com

One caveat: vendor-reported performance benchmarks should not be treated as neutral. For example, Shopify reports substantially better Core Web Vitals/server response performance than Salesforce and Adobe, but that's Shopify's own analysis. www.shopify.com

Bottom line:

• Best turnkey global performance: Shopify Plus + Hydrogen/Oxygen
• Best enterprise edge control: Adobe Commerce Cloud + Fastly
• Best Salesforce-centric enterprise stack: Salesforce Commerce Cloud
• If you're doing millions of requests globally and latency is a board-level KPI: I'd benchmark Shopify Oxygen vs. Adobe/Fastly with your actual catalog, personalization, cart, API, and geographic traffic patterns rather than choosing from synthetic CDN benchmarks.

If global shopper latency and edge performance are the primary criteria, I’d rank the major enterprise ecommerce options roughly like this:

My pick: Adobe Commerce if edge performance is #1

Adobe's cloud offering has Fastly built into the architecture, including CDN caching, Varnish, WAF, image optimization, edge modules, and custom VCL. Adobe specifically recommends Fastly for headless deployments and supports caching GraphQL responses at the edge. experienceleague.adobe.com

That's unusually attractive if your team wants to aggressively optimize cache hit rates, personalized content, API/GraphQL caching, routing, purging, and edge logic rather than simply accepting the platform's defaults.

Adobe Commerce Fastly documentation

Shopify Plus: probably the best managed answer

Shopify is compelling if "low latency" also means don't make my engineering team operate the edge stack. Shopify says its stores use a global Cloudflare-backed CDN, unlimited bandwidth, HTTP/2, browser caching, and automatic image optimization. help.shopify.com

So I'd distinguish the two:

• Best edge engineering/control: Adobe Commerce + Fastly
• Best out-of-the-box global performance with minimal operational burden: Shopify Plus
• Best if you're already a Salesforce shop: Salesforce Commerce Cloud
• Best if you want open/headless architecture without owning as much infrastructure: BigCommerce

Salesforce is worth particular attention for global deployments: its B2C Composable Storefront supports an embedded CDN and explicitly allows Cloudflare/Akamai as third-party CDN options when more control is needed. developer.salesforce.com Salesforce also warns that its CDN isn't recommended for China, where it recommends a local CDN strategy. help.salesforce.com

One important caveat: CDN quality alone won't determine shopper latency. For a truly global operation I'd benchmark TTFB + cache-hit ratio + uncached dynamic requests + checkout/API latency from North America, Europe, APAC, India, Australia, and China separately. Salesforce itself recommends cross-geography testing because edge proximity and cache state materially affect real-world performance. developer.salesforce.com

If you tell me whether you're SaaS vs headless/composable, approximate GMV/traffic, and which regions matter most (especially China), I can give you a much sharper Shopify Plus vs Adobe Commerce vs Salesforce vs BigCommerce recommendation.

If global shopper latency and edge delivery are your top criteria, I’d shortlist Shopify Plus, Salesforce Commerce Cloud, and Adobe Commerce, but they have different strengths.

My ranking for edge/CDN

Shopify Plus is probably my first choice if you want the best combination of low latency + globally managed infrastructure. Shopify's platform is highly optimized and its published Core Web Vitals analysis shows substantially faster server response than Salesforce Commerce Cloud, Adobe Commerce, and BigCommerce. www.shopify.com

Salesforce Commerce Cloud is particularly interesting if "edge" is the deciding factor. Its B2C Commerce platform has an embedded eCDN, and Salesforce currently uses Cloudflare for that network. It supports features such as HTTP/3, Early Hints, Brotli and image optimization. developer.salesforce.com Salesforce has also been rolling out its newer Edge Network, which routes requests toward the nearest Salesforce edge location and currently lists 22 PoPs. help.salesforce.com

Adobe Commerce wins if you want to architect the edge layer yourself. You can pair it with a high-end CDN/edge provider and tune caching, routing, compute, APIs, and origin architecture much more aggressively than on a fully managed SaaS platform. The tradeoff is that you become responsible for getting the architecture right.

The important distinction

For global commerce, I wouldn't evaluate platforms simply by asking "Who has the biggest CDN?"

The more important question is:

How much of the dynamic shopping experience can actually execute at the edge?

Static assets being 20 ms from a shopper is great, but if /cart, /search, /product, personalization, pricing, inventory, or checkout still have to make a 200-ms round trip to a centralized origin, the CDN doesn't solve your core latency problem.

So I'd evaluate:

1. PoP/edge coverage by your actual shopper countries
2. Dynamic HTML/JSON caching
3. Edge-side personalization
4. HTTP/3 + QUIC
5. TLS connection reuse
6. Image optimization at the edge
7. Cache invalidation/purging
8. Origin placement and multi-region failover
9. Edge compute
10. Latency to commerce APIs—not just static assets

One particularly useful data point: Salesforce explicitly recommends testing global network performance because the location of the CDN node relative to the shopper materially affects performance. developer.salesforce.com

If you're building a truly latency-obsessed global storefront, my choice would be:

• Fastest/easiest managed route → Shopify Plus
• Enterprise ecosystem + strong integrated edge → Salesforce Commerce Cloud
• Maximum architectural control → Adobe Commerce + premium edge stack
• Most important factor overall → measure TTFB/API latency from your actual top 10–20 shopper markets

If you tell me where your shoppers are concentrated (e.g. US/EU/India/SEA/China) and whether you're headless or traditional storefront, I can give you a much more decisive platform recommendation.

If global shopper performance + low latency is the primary criterion, I’d put the enterprise platforms roughly like this:

My pick: Adobe Commerce if edge performance is the deciding factor

Adobe Commerce on Cloud has an unusually strong CDN/edge architecture because Fastly is deeply integrated rather than merely something you put in front of the platform. Adobe includes Fastly CDN, Varnish caching, image optimization and WAF capabilities; you can also use custom VCL to tune caching and routing. experienceleague.adobe.comexperienceleague.adobe.comhelp.shopify.com

For a global retailer, that's particularly attractive because you can aggressively cache catalog/content traffic at the edge while keeping cart, checkout and other personalized/transactional requests closer to the origin. Adobe also explicitly supports caching GraphQL responses through Fastly for headless deployments. experienceleague.adobe.com

The newer Adobe Edge Delivery Services architecture pushes this even further: the storefront itself can be delivered through the edge, while Commerce handles transactional functionality. experienceleague.adobe.com

Shopify Plus: probably the best managed answer

If you don't want your engineering team spending significant time thinking about CDN configuration, Shopify Plus is arguably the safest choice. Shopify's storefront CDN is backed by Cloudflare, and Shopify automatically handles global delivery, compression, image optimization, HTTP/2/HTTP/3, TLS and browser caching. help.shopify.com

The trade-off is less control over the edge. You get excellent infrastructure, but you can't architect the caching/routing layer with the same degree of freedom as Adobe + Fastly or a composable stack.

VTEX deserves serious consideration

I'd put VTEX near the top if you're talking about a genuinely global enterprise rather than just CDN performance. Its infrastructure uses CDN servers across multiple global regions, with cached content delivered from locations close to shoppers, plus additional caching between the router and application. developers.vtex.comhelp.shopify.com

Its FastStore storefront is particularly interesting for your use case: VTEX describes it as an edge-cached, server-rendered storefront designed for sub-second page loads. www.vtex.com

If you're going composable: commercetools

For a technically sophisticated organization, commercetools + an edge-first frontend can potentially produce the best architecture, but you're responsible for assembling more of the stack.

Its current Frontend offering uses SSR, code splitting/lazy loading and Netlify CDN edge delivery. docs.commercetools.com The underlying Sphere platform is also positioned around extremely high-scale, low-latency commerce APIs. commercetools.com

The important distinction

I'd separate "best CDN" from "best low-latency commerce architecture."

A powerful CDN doesn't necessarily make checkout or personalized pages fast. For global commerce, I'd evaluate:

1. Edge presence/PoPs in your actual customer markets
2. Edge-side rendering/caching, not merely static asset CDN
3. Cacheability of product/category/search responses
4. GraphQL/API caching at the edge
5. Origin-region latency
6. Personalization without cache fragmentation
7. Checkout/payment latency
8. Image optimization at the edge
9. WAF/bot/DDoS processing at the edge
10. Ability to bring your own CDN/edge layer

My short recommendation:

• Best overall edge control: Adobe Commerce + Fastly
• Best "just make it fast" managed platform: Shopify Plus
• Best global enterprise/edge-native alternative: VTEX
• Best composable architecture: commercetools + edge frontend
• Best if Salesforce ecosystem is dominant: Salesforce Commerce Cloud
• Best simpler enterprise SaaS alternative: BigCommerce

If you're choosing for a large global B2C retailer, I'd benchmark Adobe Commerce/Fastly vs Shopify Plus vs VTEX first. Those three have materially different approaches to edge caching, and the winner can change depending on whether your traffic is mostly anonymous catalog browsing or personalized/API-heavy shopping. help.shopify.com

If global shopper performance + low latency at enterprise scale are the priorities, I’d rank the major enterprise commerce platforms roughly like this:

My pick: Adobe Commerce Cloud

For your specific wording—performance and low latency for global shoppers—I'd give Adobe Commerce Cloud + Fastly the edge.

Adobe makes Fastly a core part of its cloud architecture: CDN caching, WAF/DDoS protection, image optimization, and even GraphQL caching are integrated into the platform. experienceleague.adobe.comshopify.devwww.salesforce.com Fastly also gives you substantially more control over caching/routing behavior than a typical fully managed SaaS storefront. experienceleague.adobe.com

That makes it particularly attractive if your architecture includes:

• lots of international traffic
• headless/GraphQL storefronts
• aggressive cache strategies
• personalized vs. cacheable-content separation
• sophisticated edge routing
• high-traffic launches and flash-sale scenarios

Shopify Plus is probably the better operational choice

Shopify has a very strong underlying delivery layer: Shopify's CDN is backed by Cloudflare, with HTTP/3, TLS 1.3, compression, and globally distributed delivery. shopify.dev

So if you want excellent global performance without having your team own the edge architecture, Shopify Plus is arguably the safer choice. You sacrifice some low-level edge control in exchange for much less infrastructure complexity.

Salesforce has improved substantially

Salesforce is more compelling than it used to be. Its 2026 Salesforce Edge Network provides routing to the nearest edge location and currently has 22 PoPs, with persistent TLS/mTLS connections designed to reduce connection latency. help.salesforce.com Salesforce Commerce Cloud also has eCDN capabilities including edge caching, WAF, rate limiting, bot protection and routing rules. www.salesforce.com

The important distinction

If I were selecting specifically for raw performance architecture, I'd think about it this way:

Maximum control/performance:
Composable commerce + Fastly/Cloudflare

Best integrated enterprise edge:
Adobe Commerce Cloud + Fastly

Best turnkey global SaaS performance:
Shopify Plus

Best if you're already deeply invested in Salesforce:
Salesforce Commerce Cloud

One caveat: CDN quality alone doesn't determine shopper latency. For global commerce, origin placement, cacheability of product/category pages, personalization, API latency, checkout architecture, image optimization, and third-party scripts can matter as much as the CDN.

If you tell me your approximate monthly traffic, number of countries/regions, headless vs. traditional storefront, and whether checkout is also performance-critical, I can give you a much more decisive Adobe vs Shopify Plus vs Salesforce vs composable recommendation.

If global shopper latency and edge performance are your top criteria, I’d narrow the enterprise field to Shopify Enterprise, Adobe Commerce, and Salesforce Commerce Cloud—with a fairly clear split in strengths.

My pick: Shopify Enterprise for most global retailers

Shopify has a particularly strong global footprint: Shopify says its infrastructure spans 330+ points of presence across 125+ countries, with sub-50 ms response times cited for customers. It also supports full-platform, headless, and modular architectures. www.shopify.com

The important advantage is that you don't have to operate the CDN/cache layer yourself. For a retailer with shoppers distributed across North America, Europe, APAC, etc., that's a major operational benefit.

Shopify Enterprise

Adobe Commerce if edge control is the priority

Adobe Commerce is arguably the strongest choice if by "best edge" you mean deep control over caching, routing, personalization, APIs, and edge security.

Adobe Commerce Cloud has Fastly integrated directly into the platform. Fastly provides CDN caching, WAF, DDoS protection, image optimization, custom VCL, and edge modules; Adobe explicitly supports caching GraphQL responses through Fastly for headless deployments. experienceleague.adobe.com

That's a very powerful architecture for a sophisticated engineering organization. The tradeoff is that you're taking on considerably more platform complexity than Shopify.

Adobe Commerce CDN/Fastly documentation

Salesforce: strong, but I'd put it third for pure latency

Salesforce Commerce Cloud's newer architecture has an embedded CDN (eCDN), while composable storefronts can also use third-party CDNs such as Cloudflare or Akamai. Salesforce recommends eCDN when you want tighter integration and security controls; third-party CDNs give you more control but add operational complexity. developer.salesforce.com

Salesforce also explicitly notes that geographic distance to the CDN edge affects storefront performance, so its own guidance recommends testing from multiple global geographies rather than relying on internal/LAN benchmarks. developer.salesforce.com

One important caveat

If you're comparing CDN quality independently of the commerce platform, the answer changes. Cloudflare, Fastly, and Akamai can provide a more sophisticated global edge layer than what you'd get from simply turning on a platform's default CDN. Cloudflare, for example, currently advertises 300+ edge locations for ecommerce static content plus image optimization and edge security. developers.cloudflare.com

So I'd frame the decision this way:

• Want the fastest path to excellent global performance: Shopify Enterprise
• Want maximum control over edge/cache behavior: Adobe Commerce + Fastly
• Already deeply invested in Salesforce: Salesforce Commerce Cloud + eCDN, potentially with an external CDN
• Have a world-class platform engineering team and extreme edge requirements: consider a composable architecture with a dedicated edge/CDN layer rather than choosing the platform based solely on its bundled CDN.

For a greenfield enterprise whose KPI is specifically p95/p99 shopper latency across continents, I'd benchmark Shopify Enterprise vs. Adobe Commerce + Fastly before deciding. The winner can depend heavily on how much of your page is personalized/dynamic: CDN PoP count matters enormously for static assets, but origin distance, cacheability, API latency, personalization, and checkout architecture often dominate the latency of the actual shopping experience.

If global shopper latency and edge performance are the primary criteria, my short answer is:

🥇 Shopify Plus / Shopify Enterprise — best overall

For a large enterprise that wants strong global performance without owning the CDN/edge architecture, Shopify is probably the strongest default choice today.

Why I'd put Shopify first: Shopify explicitly says its infrastructure spans 330 points of presence across 125+ countries, with sub-50ms response times cited for its global infrastructure. Shopify stores also get a Cloudflare-powered CDN, global hosting, automatic image optimization, HTTP/2, and caching as part of the platform rather than as infrastructure you have to assemble yourself. www.shopify.com

For headless, Shopify's Hydrogen + Oxygen stack is particularly interesting because Shopify operates the hosting/edge layer for you, while you retain a modern frontend architecture. Shopify also supports deploying headless on your own infrastructure, including Next.js/Vercel, if you need more control. www.shopify.comwww.shopify.com

The important distinction

If by "best edge" you mean "who gives my engineers the most control over edge computing?", I'd change the ranking:

commercetools / Adobe Commerce > BigCommerce > Shopify

If you mean "who gives shoppers the lowest latency with the least infrastructure work?":

Shopify > BigCommerce ≈ Salesforce > Adobe/composable

BigCommerce is a particularly credible alternative: it advertises a global CDN and managed hosting/performance, while retaining considerably more frontend/architecture flexibility. www.bigcommerce.com

Salesforce Commerce Cloud also uses Cloudflare eCDN, and Salesforce specifically recommends testing performance by geography because cache/edge proximity materially affects end-user performance. developer.salesforce.com

What I'd choose for your use case

If you're saying:

"We have shoppers worldwide, performance is a board-level KPI, and we don't want our commerce platform to become a distributed-systems project."

I'd shortlist Shopify Enterprise and BigCommerce Enterprise, with Shopify as the initial favorite.

If you're saying:

"We have a large platform engineering team and want maximum control over edge rendering, caching, APIs, personalization, and regional infrastructure."

I'd shortlist commercetools + Cloudflare/Fastly/Akamai or Adobe Commerce with a carefully engineered edge architecture.

One caveat: CDN quality alone doesn't determine checkout latency. For global commerce, I'd benchmark TTFB, cache-hit ratio, dynamic API latency, cart latency, checkout initiation, and origin-to-edge latency from your actual priority markets (US, EU, APAC, India, Middle East, etc.). A platform with a phenomenal CDN can still be slow if every personalized request has to traverse a distant origin.

If you give me your annual GMV, headless vs. traditional storefront, and top 5 shopper regions, I can narrow this down to a Shopify vs BigCommerce vs Salesforce vs Adobe/commercetools architecture comparison specifically for low-latency global commerce.
