Problem

Expose private OpenClaw services to authenticated control clients without opening internal infrastructure broadly.

Architecture

  • Edge proxy entrypoint
    • All traffic enters through Workers routing layer.
  • Zero-trust authentication
    • Per-request token validation before forwarding.
  • VPC-aware routing
    • Policy-driven hostname + path resolution for private upstreams.
  • Rate limiting and abuse controls
    • Conservative defaults at edge and circuit-breaker behavior on failure.
  • Response hardening
    • Header sanitation and consistent error contracts.

Technical Details

  • Split request path into control-plane versus data-plane actions.
  • Strong validation of method/path/headers before any backend call.
  • Retry/timeout budgets tuned to avoid thread exhaustion when upstream is degraded.
  • Logging at ingress with minimal PII, plus trace IDs for cross-layer debugging.

Engineering Tradeoffs

  • Edge compute is cheap and globally distributed, but debugging distributed network policy requires strong trace correlation.
  • JWT verification at edge reduces backend load, but key rotation must be carefully synchronized.
