Where each one falls short

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

CloudWatch

  • The free tier covers 5 GB of log ingestion and 10 custom metrics a month, after which log ingestion is $0.50 per GB from 5 to 30 GB
  • Custom metrics are $0.30 each for the first 10,000, so instrumenting broadly gets expensive before volume discounts apply
  • Each custom dashboard beyond the free three is $3 a month
  • Alarms are billed at $0.10 per alarm metric a month, with high-resolution alarms costing more
  • Log storage beyond the free 5 GB is $0.03 per GB per month on top of the ingestion charge

Elasticsearch Service

  • The 99.95 percent monthly uptime SLA applies only to the Platinum and Enterprise subscription tiers
  • Serverless does not yet support traffic filtering, cross-project search or bring-your-own-key encryption
  • Serverless runs on AWS, GCP and Azure only, against 60 regions for the hosted option
  • Per-unit prices are not published; hosted is resource-based and serverless usage-based
