Workshop demo · Lambda vs. Workers

Deterministic compute, at the edge or in the cloud.

PulseCompute runs a pure, stateless CPU job and reports exactly which runtime served it. Deploy the same Next.js app to Cloudflare Workers and AWS Lambda and compare cold starts, latency, and cost head-to-head.

Deterministic compute

Every call runs a fixed FNV-1a hash loop and returns a constant-size payload. Same input, same checksum — perfect for measuring the platform, not the app.

One app, two platforms

The exact same Next.js codebase ships to Cloudflare Workers (vinext deploy) and AWS Lambda (OpenNext: CloudFront → Lambda Function URL). No per-platform forks.

Stateless by design

No database, no cache, no cold data to warm. The only variable is the runtime: a V8 isolate at the edge vs. a Node container in one region.
