Where each one falls short

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

Argo CD

  • The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

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
