For a web app that needs serverless functions, I’d shortlist these:

My recommendation

For most new web applications, I'd pick Google Cloud or AWS.

1. Google Cloud — best overall balance

Cloud Run is particularly attractive because you can deploy a normal web service/container and have it scale to zero, while Cloud Run functions gives you traditional event-driven serverless functions. cloud.google.comcloud.google.com

That makes it a good choice if you expect your architecture to evolve from:

frontend → API functions → database

into something more substantial like:

frontend → API → containers/services → queues/jobs → database

You aren't boxed into the function model.

2. AWS — best if you expect significant scale or complexity

AWS Lambda is extremely mature and integrates with a huge number of AWS services. AWS's serverless stack includes Lambda, API Gateway, DynamoDB, event services, queues, etc. docs.aws.amazon.com

I'd choose AWS if you already know you'll need things like complex event processing, queues, sophisticated IAM, or a large enterprise ecosystem.

3. Cloudflare — best for lightweight, globally distributed applications

If your functions are primarily HTTP APIs, authentication logic, webhooks, request processing, or edge logic, Cloudflare can be compelling. It's especially interesting when latency around the world matters more than access to a huge catalog of backend infrastructure.

4. Azure — best when you're already Microsoft-centric

Azure Functions provides HTTP, scheduled, queue, database, and other event triggers, with particularly strong integration into the Microsoft/.NET ecosystem. Microsoft's current recommendation for new serverless workloads is the Flex Consumption hosting model. learn.microsoft.com

A practical architecture

For a typical SaaS/web app, I'd seriously consider:

Frontend: your existing framework
Serverless backend: Google Cloud Run / Cloud Run functions
Database: managed PostgreSQL
Files: object storage
Async work: managed queue
CDN/DNS: Cloudflare

One nice aspect of Google Cloud is that Cloud Run can handle both conventional containerized services and functions, and it scales down to zero when unused. cloud.google.comcloud.google.com

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether you're starting from scratch, I can narrow this down to the best 2–3 setups and compare likely cost/complexity.

For a web app that needs serverless functions, the best provider depends on your stack, traffic pattern, and how much cloud infrastructure you want to manage. The main choices are usually AWS, Google Cloud, Azure, Cloudflare, and frontend-focused platforms like Vercel. CIOPages

Quick recommendations

CIOPages APIScout## 1. AWS Lambda — best general-purpose choice

Amazon Web Services Lambda is usually the safest default for a serious application.

Strengths

• Huge ecosystem (databases, queues, storage, authentication, monitoring)
• Many event triggers (HTTP, queues, storage uploads, scheduled jobs)
• Supports many runtimes and custom runtimes
• Good fit for APIs, background jobs, and event-driven systems

Good fit

• SaaS applications
• APIs
• Image/file processing
• Backend jobs
• Apps already using AWS services

Trade-offs

• More configuration than developer-focused platforms
• You need to understand AWS networking, IAM, and deployment patterns

CIOPages TechTarget## 2. Google Cloud Run / Cloud Functions — best if you want containers

Google Cloud is a strong option if your team likes container workflows.

Strengths

• Deploy normal containers rather than adapting everything to a function model
• Scales down when idle
• Good for APIs and backend services
• Strong fit for Google services such as Firebase, Pub/Sub, and data platforms

Good fit

• Node.js/Python APIs
• Microservices
• Apps that may outgrow traditional functions

Trade-offs

• Smaller ecosystem than AWS
• More container knowledge can be useful

CIOPages Netguru## 3. Azure Functions — best for Microsoft ecosystems

Microsoft Azure is often the right choice for organizations already using Microsoft tooling.

Strengths

• Excellent .NET/C# support
• Integrates well with Microsoft identity and enterprise services
• Durable Functions provide workflow orchestration

Good fit

• Enterprise applications
• Internal business systems
• .NET applications

Trade-offs

• Less attractive if your stack is mostly open-source web tooling

Inventive HQ TechTarget## 4. Cloudflare Workers — best for edge applications

Cloudflare Workers is different from traditional serverless functions: your code runs at Cloudflare's edge locations rather than primarily in a single cloud region.

Strengths

• Very fast startup times
• Excellent for globally distributed users
• Great for API gateways, authentication middleware, and lightweight APIs

Good fit

• Global web apps
• Low-latency APIs
• Request rewriting/authentication
• Edge logic

Trade-offs

• Runtime limitations compared with full cloud VMs/functions
• Not ideal for heavy computation or large dependencies

Inventive HQ Veld Systems## 5. Vercel Functions — best for frontend teams

Vercel is a strong choice if your app is built around frameworks like Next.js.

Strengths

• Very simple deployments
• Excellent frontend developer experience
• Built-in routing, previews, and CI/CD workflows

Good fit

• Next.js apps
• Marketing sites with backend APIs
• Small-to-medium SaaS products

Trade-offs

• Less control than running directly on AWS/GCP/Azure
• Can become expensive at larger scale

Veld Systems APIScout## My typical architecture recommendations

Small startup / MVP

• Frontend: Vercel
• Functions: Vercel Functions or Cloudflare Workers
• Database: managed PostgreSQL

Growing SaaS

• Frontend: Vercel or CloudFront
• Backend functions: AWS Lambda or Google Cloud Run
• Queue/background jobs: AWS SQS, Google Pub/Sub, or similar

Enterprise

• AWS Lambda + managed AWS services, or Azure Functions if already invested in Microsoft tooling

Global low-latency app

• Cloudflare Workers at the edge
• Traditional cloud functions for heavier backend work

For most teams building a web app today, I would shortlist AWS Lambda, Google Cloud Run, and Cloudflare Workers first, then choose based on whether you value ecosystem depth, container flexibility, or edge performance most. CIOPages Inventive HQ

Yes. For a web app with serverless functions, I’d narrow the field to Vercel, AWS, Google Cloud, and Cloudflare. The best choice depends heavily on your frontend framework and how much infrastructure you want to manage.

My recommendations

1. Vercel — easiest default for a web app

If you're using Next.js, I'd probably choose Vercel first. Functions are automatically provisioned from your application, scale with demand, and use a full Node.js runtime. Vercel also has particularly strong integration with Next.js. vercel.comvercel.com

Vercel

Good architecture:
Next.js → Vercel Functions → Postgres/Redis → external APIs

2. AWS Lambda — best if this is becoming a serious backend

Choose AWS if you expect lots of integrations, queues, event processing, authentication, storage, or other backend infrastructure. Lambda integrates natively with 220+ AWS services and scales automatically. aws.amazon.com

AWS Lambda

The downside is that you can quickly end up managing API Gateway, IAM, CloudWatch, SQS, EventBridge, databases, deployment tooling, etc. It's extremely powerful but considerably more complex than Vercel.

3. Google Cloud Run — excellent middle ground

I'd seriously consider Google Cloud if your functions might eventually become more substantial backend services. Cloud Run functions are deployed on Cloud Run, automatically scale, and can be invoked through HTTP or events. You can also deploy containerized services when a "function" stops being enough. cloud.google.com

Google Cloud Run

This is particularly attractive if you're doing AI/ML, document processing, image processing, or other workloads where containers are useful.

4. Cloudflare Workers — best for globally distributed applications

Cloudflare is compelling if latency matters and you want backend logic running close to users around the world. Workers deploy globally across Cloudflare's network and use lightweight V8 isolates rather than traditional server processes. www.cloudflare.com

Cloudflare Workers

The important caveat is runtime compatibility: Workers isn't simply "AWS Lambda but faster." It's a different execution environment, so some Node.js packages and assumptions don't translate directly. vercel.comvercel.com

What I'd pick

• Next.js/React startup: Vercel
• General-purpose enterprise backend: AWS Lambda
• Backend + containers + AI/data workloads: Google Cloud Run
• Global edge application/API: Cloudflare Workers
• Simple frontend + functions: Netlify

If you tell me your frontend framework (Next.js, React/Vite, Vue, etc.), backend language, database, expected traffic, and whether this is a startup/MVP or production enterprise app, I can recommend a concrete architecture and compare the likely costs.

For a web app that needs serverless functions, the “best” cloud provider depends on your stack, traffic pattern, and how much infrastructure you want to manage. The strongest options today are: www.ciopages.com

inventivehq.comveldsystems.com

My usual recommendations by scenario

1. General-purpose SaaS/web app

• Pick AWS Lambda if you expect your backend to grow:
  • APIs
  • background jobs
  • queues
  • scheduled tasks
  • integrations
  • complex permissions
• AWS has the broadest serverless ecosystem. www.ciopages.com

Typical architecture:

• Frontend: Vercel, S3/CloudFront, or similar
• API: Lambda + API Gateway
• Database: RDS, DynamoDB, Aurora, or managed PostgreSQL
• Async work: SQS/EventBridge

2. Next.js or frontend-first application

• Pick Vercel.
• It is usually the fastest path from Git commit → deployed app → serverless API routes. inventivehq.comveldsystems.com

Good for:

• marketing sites
• SaaS MVPs
• dashboards
• content platforms

3. Global users and latency-sensitive APIs

• Pick Cloudflare Workers.

Good for:

• authentication middleware
• edge APIs
• request routing
• personalization
• lightweight APIs

The tradeoff is that edge runtimes are more constrained than traditional cloud functions. inventivehq.com

4. Existing enterprise environment

• Already using Microsoft 365, Entra ID, .NET, Azure DevOps? → Azure Functions.
• Already using Google Cloud, BigQuery, Firebase, or Kubernetes? → Google Cloud Functions/Cloud Run.
• Already using AWS services? → Lambda.

A practical shortlist

For most teams building a new web app, I would narrow it to:

1. AWS Lambda — safest long-term default
2. Vercel Functions — easiest for modern frontend teams
3. Cloudflare Workers — best for edge performance
4. Google Cloud Run/Functions — best if you prefer containers and Google’s ecosystem
5. Azure Functions — best for Microsoft-centric organizations

One architecture that works well today is a hybrid:

• Vercel or Cloudflare for frontend delivery
• Serverless functions for APIs
• Managed database (Postgres, DynamoDB, etc.)
• Queue-based workers for heavy jobs

If you share your stack (React/Next.js, Vue, Python, Node, .NET, etc.), expected traffic, and whether you need a database or background jobs, I can narrow this down to a specific setup.

Yes. For a web app that needs serverless backend functions, I’d shortlist these:

My recommendation

If you're building a typical modern web application:

• Next.js + want the easiest deployment → Vercel
• React/Next.js + substantial backend → AWS or Google Cloud
• Need maximum architectural flexibility → AWS Lambda
• Want serverless but also want to run arbitrary containers → Google Cloud Run
• Need Microsoft/.NET/Azure integration → Azure Functions
• Latency at the edge is a major requirement → Cloudflare Workers

AWS Lambda is particularly strong if you expect the application to grow into a larger backend: it automatically scales, uses pay-per-use billing, and integrates with 220+ AWS event sources. aws.amazon.com

I'd give Google Cloud Run serious consideration for a new application, though. Google's current model combines traditional serverless functions with container-based Cloud Run, so you can start with simple functions and move toward more sophisticated services without changing platforms. Cloud Run can scale from essentially zero to very large workloads and supports direct container deployment. docs.cloud.google.com

One useful distinction: "serverless function" doesn't necessarily mean Lambda-style functions anymore. Cloud Run, for example, lets you deploy containerized applications while Google handles provisioning and scaling. That can remove some of the execution/runtime limitations associated with traditional FaaS. cloud.google.com

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether you're starting from scratch, I can narrow this down to the best 2–3 architectures and an estimated monthly cost.

Yes. For a web app with serverless functions, I’d narrow the field to AWS, Google Cloud, Azure, and Cloudflare. The best choice depends mostly on how complex your backend is and whether you want a full cloud ecosystem or a simpler web-focused platform.

My recommendations

1. AWS Lambda — best general-purpose choice

Amazon Web Services is probably the safest choice if this application is expected to grow substantially. Lambda automatically scales and integrates with API Gateway, S3, SQS, EventBridge, databases, authentication, and hundreds of other AWS services. aws.amazon.com

A typical architecture would be:

Frontend → API Gateway → Lambda → database/storage

Lambda functions can run for up to 15 minutes, and AWS charges based on requests and execution duration. aws.amazon.com

Choose it if: you expect a fairly sophisticated backend or want the broadest range of cloud services.

2. Google Cloud Run — my favorite for containerized web apps

Google Cloud's Cloud Run is particularly attractive if your developers like Docker or you want more flexibility than traditional functions provide. It can run containers, automatically scale, and scale to zero when unused. Google also has Cloud Run functions for conventional event-driven functions. cloud.google.com

Choose it if: you want serverless but don't want to constrain your backend to a narrow function runtime.

3. Cloudflare Workers — best for a modern web-first application

Cloudflare Workers are compelling when latency and simplicity are priorities. Functions run across Cloudflare's global network, with automatic scaling and a runtime designed for very fast startup. developers.cloudflare.com

Cloudflare also offers storage, databases, queues, and other primitives, so you can build a fairly complete application without assembling a traditional cloud stack. developers.cloudflare.com

The paid Workers plan currently starts at $5/month, with usage-based charges beyond the included allocation and no additional egress/throughput charges. developers.cloudflare.com

Choose it if: this is primarily a web/API application and you value fast global responses and operational simplicity.

4. Azure Functions — best if you're already Microsoft-centric

Microsoft Azure Functions is a strong option for .NET/C#, Microsoft Entra ID, SQL Server, and other Azure services. Azure currently recommends its Flex Consumption hosting option for new serverless applications. learn.microsoft.com

Choose it if: your organization already uses Azure/Microsoft heavily.

What I'd choose

For a new web application, I'd rank them:

Cloudflare Workers → if it's primarily a web/API product and simplicity + performance matter
AWS Lambda → if you anticipate a sophisticated backend and lots of integrations
Google Cloud Run → if you want serverless with container-level flexibility
Azure Functions → if you're already invested in Microsoft/Azure

One important architectural decision is where the frontend lives. You don't necessarily need to host the frontend and serverless functions with the same provider. For example, you can put a React/Next.js frontend on a frontend-focused platform and have its API/backend functions run on AWS, Google Cloud, or Cloudflare.

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether you're building an MVP or production system, I can recommend a concrete architecture and compare the likely costs.

Yes. For a web app that needs serverless backend functions, I’d shortlist these:

My recommendation

If this is a typical web app: start with Vercel. Its Functions automatically scale with requests, integrate directly with popular web frameworks, and Vercel handles the deployment/CDN infrastructure for you. vercel.com

If you're building something that will eventually have a substantial backend: I'd choose AWS Lambda. Lambda can respond to HTTP requests as well as hundreds of AWS event sources, scales automatically, and uses pay-per-use pricing. aws.amazon.com

If low latency around the world is particularly important: look hard at Cloudflare Workers. Functions run across Cloudflare's global network, with automatic scaling and a lightweight isolate architecture designed for very fast startup. developers.cloudflare.com Cloudflare's paid Workers plan currently starts at $5/month, with usage-based charges and no additional data-transfer/egress charges. www.cloudflare.com

A practical architecture

For example:

Frontend → Vercel/Cloudflare → serverless functions → managed database

Your functions can handle:

• Authentication/session logic
• CRUD APIs
• Payments/webhooks
• Third-party API calls
• Email notifications
• Background jobs
• Scheduled tasks

You don't necessarily need to put your database on the same provider. For example, Cloudflare Workers can connect to external databases and private services, including infrastructure in AWS, Azure, and GCP. cloudflare-docs.cloudflare-docs.workers.dev

If you tell me your frontend framework (Next.js/React/Vue/etc.), backend language, database, expected traffic, and whether you're optimizing for cost or scalability, I can narrow this to the best 2–3 setups for your app.

Yes. For a web app with serverless functions, I’d shortlist these four:

My recommendations

1. AWS Lambda — safest general-purpose choice

Amazon Web Services's Lambda is probably the default choice if you expect the backend to grow into a fairly sophisticated system. Functions can respond to HTTP requests as well as 220+ AWS event sources, and Lambda automatically scales without you managing servers. Individual invocations can run for up to 15 minutes. aws.amazon.com

I'd choose it if you expect to use things like S3, SQS, EventBridge, DynamoDB, RDS, or other AWS services.

AWS Lambda

2. Google Cloud Run — my pick if you want maximum flexibility

Google Cloud's Cloud Run is particularly attractive because you can deploy a normal container rather than adapting everything to a proprietary function runtime. Google describes Cloud Run as a fully managed serverless platform for containerized applications, while Cloud Run functions provides the more traditional function model. docs.cloud.google.com

This is a strong choice if your app has a Node/Python/Go/etc. backend and you want the option to move toward a conventional containerized service later.

Google Cloud Run

3. Cloudflare Workers — excellent for a modern web-first application

Cloudflare Workers is compelling if your app is primarily web/API traffic and you care about global latency. Workers execute across Cloudflare's global network, and Cloudflare says they run in 330+ cities by default. It also provides integrated storage, queues, databases, and other primitives. www.cloudflare.com

The big caveat is that Workers isn't simply "Node.js in the cloud." Its runtime is based around web APIs and isolates, with only a subset of Node APIs available. developers.cloudflare.com

Cloudflare Workers

4. Azure Functions — choose it if you're already Microsoft-centric

Microsoft Azure Functions makes the most sense if you're already using Azure, .NET, Microsoft Entra ID, SQL Server, Service Bus, or other Microsoft infrastructure. Otherwise, I'd generally put AWS Lambda or Cloud Run ahead of it for a new web application.

Azure Functions

What I'd pick for a new web app

If you gave me no other constraints:

Cloud Run → best balance of simplicity, portability, and backend flexibility.

AWS Lambda → best if you expect a large AWS-native architecture.

Cloudflare Workers → best if it's a web-heavy app where edge performance is important.

Azure Functions → best if you're already invested in Microsoft/Azure.

One other important distinction: "serverless functions" doesn't necessarily mean you should use a FaaS product. For a web application with several API endpoints, a serverless container such as Cloud Run can often be a cleaner architecture than creating dozens of individual Lambda/Function handlers.

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether you need background jobs, I can narrow this down to a specific hosting architecture and provider.

For a web app with serverless functions, I’d narrow the field to these five:

My recommendations

1. Vercel — easiest choice for a typical web app

If you're building with Next.js, React, or another modern frontend framework, I'd start here. Vercel Functions automatically scale with requests, can run near your data source, and integrate directly into the deployment workflow. vercel.com

Vercel Functions documentation

2. Cloudflare Workers — best for globally distributed applications

If latency around the world matters, Workers is particularly compelling. Functions execute across Cloudflare's global network, with automatic scaling and very fast startup. Cloudflare also gives you adjacent services such as D1, KV, R2, Durable Objects, and Queues. developers.cloudflare.com

Cloudflare Workers documentation

The paid Workers plan currently starts at $5/month, with no additional egress charges. developers.cloudflare.com

3. AWS Lambda — best for a serious AWS-based backend

Lambda is the safest choice if you expect your application to grow into a more sophisticated backend involving queues, databases, event processing, storage, authentication, workflows, etc. AWS says Lambda integrates with 220+ AWS services and automatically scales with demand. aws.amazon.com

AWS Lambda

4. Google Cloud Run — best if you want serverless without being constrained to a function runtime

Cloud Run functions can scale from a handful of invocations to millions, while Cloud Run itself lets you deploy containers. That's a nice middle ground if you think some parts of the application will eventually need more control than traditional functions provide. docs.cloud.google.com

Google Cloud Run

5. Azure Functions — best for an existing Microsoft stack

Azure Functions supports HTTP APIs, scheduled jobs, database events, queues, IoT, and durable workflows. Microsoft currently recommends the Flex Consumption hosting plan for new serverless applications. learn.microsoft.com

Azure Functions

What I'd choose

• Next.js / React SaaS: Vercel
• Globally distributed API or edge-heavy app: Cloudflare Workers
• Large backend / lots of AWS services: AWS Lambda
• Containerized backend + serverless scaling: Google Cloud Run
• .NET / Microsoft ecosystem: Azure Functions

If you tell me your frontend framework, backend language, expected traffic, database, and whether you're building a SaaS/API/e-commerce app, I can give you a concrete architecture and a Vercel vs Cloudflare vs AWS cost/complexity comparison.

For a web app that needs serverless functions, I’d shortlist these four:

My recommendation

For a typical new web app, I'd start with Cloud Run or Cloudflare Workers.

• Cloudflare Workers → best if your app is primarily HTTP/API requests and you care about global latency, simplicity, and fast deployment. Workers run across Cloudflare's global network and can also handle frontend assets, APIs, storage, queues, and scheduled jobs. www.cloudflare.com
• Google Cloud Run → best if you want normal containers/full Linux environments while retaining serverless scaling. It can scale to zero and supports applications, functions, and containerized workloads. cloud.google.com
• AWS Lambda → my pick when the application will rely heavily on AWS services such as S3, SQS, DynamoDB, EventBridge, etc. Lambda has integrations with 220+ AWS event sources and automatically scales with demand. aws.amazon.com
• Azure Functions → particularly attractive if you're already using Azure, Microsoft 365, .NET, Service Bus, or other Microsoft infrastructure. Azure currently recommends its Flex Consumption hosting model for new serverless apps. learn.microsoft.com

A practical architecture

For example, a relatively clean setup could be:

Frontend → Cloudflare/Vercel → Serverless API → PostgreSQL

with serverless functions handling things like:

• authentication/session logic
• API endpoints
• payments/webhooks
• email notifications
• background jobs
• image/file processing

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether you need background jobs, I can narrow this down to the best 1–2 hosting architectures and approximate costs.

For a web app that needs serverless functions, the “best” cloud provider depends heavily on your stack, traffic pattern, and how much infrastructure you want to manage. The main options fall into a few categories: hyperscale cloud platforms, frontend-focused platforms, and edge/serverless platforms. www.ciopages.com

inventivehq.com

My typical recommendations by scenario

1. You are building a normal SaaS/web app

• Best default: AWS Lambda + API Gateway (or AWS serverless containers)
• Choose this if you expect integrations, queues, databases, background jobs, or enterprise requirements.

2. Your app is Next.js / React-heavy

• Best developer experience: Vercel Functions
• You get very fast deployments and minimal infrastructure work. apiscout.dev

3. You need APIs with very low latency worldwide

• Best fit: Cloudflare Workers
• Good for authentication middleware, API gateways, personalization, edge APIs, and request processing. inventivehq.com

4. You already use a cloud ecosystem

• AWS users → Lambda
• Google users → Cloud Functions / Cloud Run
• Microsoft users → Azure Functions

This usually reduces operational overhead. www.techtarget.com

5. You want to avoid vendor lock-in
Consider:

• container-based serverless (for example Cloud Run-style deployments)
• Dockerized functions
• Kubernetes-based serverless frameworks

A common modern architecture

A lot of teams use a hybrid approach:

• Frontend hosting: Vercel / Cloudflare Pages
• API functions: Lambda, Cloud Functions, or Workers
• Database: managed PostgreSQL (RDS, Cloud SQL, Neon, Supabase, etc.)
• Background jobs: queues + serverless workers

That gives you the convenience of serverless without forcing every workload into one function runtime.

If you tell me your stack (Next.js, React, Node, Python, .NET, etc.), expected traffic, database choice, and whether you need background jobs, I can narrow this down to a recommended architecture.

If your main requirement is hosting a web app with serverless functions, I’d shortlist these:

My recommendation

For a typical startup/product web app: Vercel is probably the easiest starting point. Its Functions platform is specifically designed to run server-side code without managing servers, and it supports common API/webhook/background-task patterns. vercel.com

For a globally distributed application: I'd seriously consider Cloudflare Workers. Functions run across Cloudflare's global network, with automatic scaling and very fast startup; Cloudflare also gives you KV, D1, R2, Queues, Durable Objects, and other pieces for building a complete application. vercel.comwww.cloudflare.comdocs.aws.amazon.com Its paid Workers plan currently starts at $5/month, with no additional data-transfer/egress charges. developers.cloudflare.com

For a system you expect to grow into a sophisticated backend: AWS Lambda is the safer long-term platform choice. Lambda automatically scales and uses pay-per-use pricing, while integrating with the enormous AWS ecosystem. docs.aws.amazon.com

A simple decision rule

• Next.js/React + want minimal DevOps → Vercel
• Global edge APIs / low latency → Cloudflare Workers
• Complex backend / lots of AWS services → AWS Lambda
• Microsoft enterprise stack → Azure Functions
• GCP/data/ML ecosystem → Google Cloud

If you tell me your frontend framework (e.g. Next.js, React, Vue), backend language, database, expected traffic, and whether you need long-running jobs, I can narrow this to 1–2 architectures and estimate the likely monthly cost.

For a web app that needs serverless functions, I’d shortlist these:

My recommendation

If you're building a typical modern web app: I'd start with Vercel if you're using Next.js, or Google Cloud Run if you want more backend/container flexibility.

If this is a serious enterprise application: AWS Lambda is probably the safest long-term choice. Lambda automatically scales and integrates with a very large number of AWS services; current Lambda functions can run for up to 15 minutes per invocation. aws.amazon.com

If you expect your functions to grow into containerized services: I'd strongly consider Google Cloud Run/functions. Google has unified its Functions offering with Cloud Run, giving you function-style deployment while retaining Cloud Run's container model and scaling. docs.cloud.google.com

If you're already on Microsoft infrastructure: Azure Functions is a very good choice, particularly because Microsoft's current Flex Consumption plan is designed for event-driven scaling and pay-as-you-go serverless workloads. learn.microsoft.com

A practical architecture

For example, you could have:

Frontend → CDN/hosting → serverless API functions → managed database

And functions for things like:

• /api/auth
• /api/users
• /api/payments
• /api/webhooks
• scheduled jobs
• background processing

The biggest decision isn't really "which provider has serverless functions?"—all of the major clouds do. It's how much infrastructure control you want versus how much simplicity you want.

If you tell me your frontend framework (Next.js, React, Vue, etc.), backend language, database, expected traffic, and whether this is a startup or enterprise app, I can narrow this down to 2–3 concrete hosting architectures and compare likely costs.

For a web app with serverless functions, I’d shortlist these:

My recommendation

1. Vercel — best default for a typical web app

If you're building something like a React/Next.js application with API endpoints, authentication, database calls, webhooks, etc., Vercel is probably the smoothest choice. Vercel Functions automatically scale with requests and can scale down when idle, while supporting Node.js, Python, Go, Ruby, Rust, and other runtimes. vercel.comdocs.cloud.google.comlearn.microsoft.com

Vercel Functions documentation

2. AWS Lambda — best for a serious AWS-based backend

Choose AWS if you expect lots of integrations, queues, event processing, background jobs, or want maximum control over the surrounding infrastructure. Lambda integrates with 220+ AWS event sources and automatically scales based on demand. aws.amazon.com

AWS Lambda

3. Google Cloud Run / Cloud Run functions — best if you want containers

This is particularly compelling if your functions may eventually become more substantial services. Cloud Run can automatically scale from zero to very large workloads, while Cloud Run functions provides the simpler function-oriented model. docs.cloud.google.com

Google Cloud Run functions

4. Azure Functions — best if you're already in Microsoft's ecosystem

Azure Functions is strong for HTTP APIs, scheduled jobs, event processing, queues, and Durable Functions workflows. Microsoft currently recommends the Flex Consumption hosting plan for new applications. learn.microsoft.com

Azure Functions

What I'd choose

For most new web apps:

Next.js/React → Vercel Functions → managed database

For a backend that will grow into a broader cloud architecture:

AWS → Lambda + API Gateway + S3 + database/queue services

For applications packaged as containers:

Google Cloud → Cloud Run

The biggest decision isn't really "which provider has serverless functions?"—all of these do. It's how much cloud infrastructure you expect to manage and how much vendor ecosystem you want to adopt.

If you tell me your frontend framework, backend language, database, expected traffic, and whether you need background jobs/webhooks, I can narrow this down to a concrete hosting architecture and likely cost profile.
