The short version

  • Each has a real cost: Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations; Prometheus not suitable for per-request billing as collected data lacks 100% accuracy
  • They diverge on capability: Deno Deploy covers Edge Functions, Prometheus covers Multi-dimensional Data Model.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deno Deploy

  • Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
  • Less mature than established serverless platforms; newer company and platform
  • 1GB deployment size limit may restrict larger applications
  • 512MB memory limit lower than some competitors for memory-intensive workloads
  • Smaller user base and community compared to Lambda or Netlify

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection
