In-Depth Analysis
Cloudflare Workers
Run serverless JS/Wasm at the edge with instant cold starts
Cloudflare Workers at $5/month is among the cheapest serverless entry points, and the free tier (100K requests/day) is genuinely generous for prototyping.
Watch out
CPU time is the real billing dimension, not requests. The included 30M CPU-ms sounds generous, but a single image-processing Worker using 50ms CPU per request exhausts it after just 600K requests/month, well under the 10M request allowance
Strengths
- +Global edge network
- +Great free tier
- +Low latency
Weaknesses
- -Limited runtime
- -Different programming model
Key features
AWS Lambda
Run code without managing servers, pay only for compute time
Lambda pioneered serverless compute and remains the default choice in the AWS ecosystem.
Watch out
Duration billing rounds up to the nearest millisecond, but memory billing is per-GB-second at allocated memory (not used memory). Allocating 1 GB but using 200 MB still bills for 1 GB, right-sizing memory is critical
Strengths
- +Industry-standard serverless platform
- +Integrates with entire AWS ecosystem
- +Scales automatically to any load
- +Pay only for compute time used
- +Supports many languages and runtimes
Weaknesses
- -Cold starts can affect latency
- -Complex pricing model
- -15-minute execution time limit
- -Debugging can be challenging
- -Vendor lock-in with AWS services
