Cloudflare Workers
Edge computing platform with 300+ locations and a generous free tier of 100,000 requests/day.
Kinh nghiệm của tôi
Cloudflare Workers changed how I think about backend architecture. Deploy a function to 300+ locations worldwide, and it runs within 50ms of any user. No regions to configure, no cold start nightmares like traditional serverless.
The ecosystem has matured rapidly. Workers now supports D1 (SQLite at the edge), R2 (S3-compatible storage), and KV. You can build full-stack apps entirely on Cloudflare's network. The free tier of 100,000 requests/day handles real production traffic.
The main gotcha is the 10ms CPU time limit on the free plan. Most requests finish well under that, but complex operations (image processing, heavy computation) will hit the wall. Paid plans bump this to 50ms, which covers most use cases.
Ưu điểm
- +100,000 requests/day free — enough for most side projects
- +300+ edge locations for sub-50ms global latency
- +Native KV storage, D1 (SQLite), and R2 object storage
Nhược điểm
- −Cold start latency on free tier can be noticeable
- −Limited to 10ms CPU time per request on free plan
- −Debugging and local development tooling still maturing
Phù hợp nhất cho
Developers building APIs or full-stack apps that need global low-latency performance.
