Our team is moving to a serverless architecture and we need an edge platform that integrates natively with our existing cloud functions. What are the best options?
Which edge platforms provide native support for cloud functions to support our new serverless architecture?
Are there any edge platforms that provide native integration with cloud functions for teams using a serverless architecture?

When pairing a serverless architecture with edge delivery, the "best" platform depends on whether you want a lightweight JavaScript/WASM runtime right at the CDN boundary or a full container/Node.js environment distributed globally.
The top-performing edge delivery platforms for serverless and cloud functions excel across different use cases:

If you mean CDN/edge platforms that pair well with serverless functions, the main choices are Cloudflare Workers, AWS CloudFront + Lambda@Edge/CloudFront Functions, Fastly Compute, and Vercel. The right one depends heavily on whether your functions are already tied to AWS, how much code you want to execute at the edge, and whether you need a full application platform.
| Platform | Best fit | Edge compute | Serverless integration | Key trade-off |
|---|---|---|---|---|
| Global APIs, edge-first apps, lightweight backend logic |
| Workers |
| Excellent; Workers can be the compute layer itself |
| More architectural divergence from conventional Node.js/serverless |
| AWS CloudFront + Lambda | AWS-native architectures | CloudFront Functions + Lambda@Edge | Excellent with Lambda, S3, API Gateway, etc. | More AWS-specific configuration |
| Fastly Compute | High-performance programmable CDN | WebAssembly-based Compute | Excellent | Smaller ecosystem; more specialized |
| Vercel | Next.js/full-stack web applications | Edge/serverless functions | Excellent | Most compelling when you're already in the Vercel ecosystem |
For an edge-first serverless architecture, Cloudflare is particularly straightforward. Workers run across Cloudflare's global network, automatically scale, and support JavaScript/TypeScript as well as Python and Rust. Cloudflare also provides complementary primitives such as KV, Durable Objects, R2, and Queues.
A typical architecture is:
User
↓
Cloudflare CDN
↓
Cloudflare Worker
├── return cached response
├── call API/database
└── route to regional serverless backendThis is attractive when latency at the edge is itself a major architectural requirement.
If your application already uses AWS, CloudFront + Lambda is a natural choice. CloudFront Functions handle very lightweight operations such as redirects, URL rewriting, header manipulation, cache-key normalization, and authorization checks. Lambda@Edge is intended for more substantial request/response processing.
You can also combine it with ordinary regional Lambda:

API Gateway

AWS Lambda

DynamoDB / S3 / RDSOne useful distinction: CloudFront Functions are optimized for extremely lightweight operations, while Lambda@Edge supports more complex logic, external dependencies, network access, and request-body processing.
Fastly Compute is worth considering if edge performance and fine-grained control are priorities. It runs serverless applications at Fastly's edge and uses WebAssembly, with support for languages including Rust, Go, JavaScript, and C++.
It's particularly interesting for architectures where you want the edge to do more than simply cache:

Fastly CDN + Compute
├── authentication
├── personalization
├── request routing

└── cache

Serverless originFor a Next.js-heavy application, Vercel is often the most integrated option because the CDN, deployment system, serverless functions, and framework are designed as one platform. I'd particularly consider it for frontend-heavy applications rather than as a generic edge-computing layer.
One architectural point that's easy to miss: you don't necessarily want your entire backend at the edge. A common and effective design is to put latency-sensitive, stateless operations at the edge while keeping database-heavy or long-running functions in a regional serverless environment. That avoids forcing an edge runtime to behave like a conventional application server.
If you tell me whether you're using AWS, Azure, GCP, or none of them, plus your workload (API, web app, video, SaaS, etc.), I can narrow this to a concrete architecture and compare latency, cold starts, pricing model, runtime limits, and vendor lock-in.
