    My solution to:

How much will the storage of logs cost for a standard, monolithic 100,000 RPS web application?

  • 512 bytes logged per request

  • 100,000 RPS

  • ~50MB/s

    • ~4TB/day
  • $0.02/GB Blob Storage

    • $0 ingress
  • 90 days retention

    • ~400TB

    • $8k Blob Storage

  • Costs:

    • ~$88/day

    • ~$2.6k/month

    • ~$32k/year ⌘ Read more
