Where each one falls short

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

CosmosDB

  • Autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used
  • Provisioned throughput is charged in every region the account is replicated to, so multi region accounts multiply the RU bill
  • Storage charges cover data, indexes and backups in each replicated region
  • Egress out of Azure and between regions is charged, though ingress is free
  • The free allowance is one account per Azure subscription, limited to 1,000 RU/s and 25 GB
  • RU/s rates vary by region and are only shown through the pricing calculator rather than a flat published rate

Hetzner Cloud

  • Cost-Optimized plans are shown as currently unavailable
  • The shared-resource tiers are positioned for variable usage and development rather than sustained production workloads
  • Regions are limited to Germany, Finland, the United States and Singapore, so latency to other markets is a real constraint
  • The uptime guarantee is 99.9 percent, below what the large hyperscalers offer on comparable services
  • Support is 24/7 by email, without a phone channel
