The short version

  • They diverge on capability: Azure Monitor covers Log collection, Cloudflare covers Global CDN.

Where each one falls short

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

Azure Monitor

  • Billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
  • Only the first 5 GB a month of Analytics logs is free per billing account
  • Retention beyond the base period is charged per GB per month, up to 2 years interactive and 12 years long term
  • Log queries and search jobs are billed per GB scanned, so investigating an incident costs money
  • Alert rules are billed per time series for metrics and by execution frequency for logs
  • The pricing page shows placeholders rather than rates until a region and currency are chosen

Cloudflare

  • Free tier limited to basic features (no advanced analytics or premium features)
  • Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
  • Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
  • Geographic coverage limited to announced 330+ cities (may not cover all regions globally)
