Where each one falls short

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

Consul

  • Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
  • Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
  • Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
  • Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
  • Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
  • HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead

Microsoft Azure

  • The 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services
  • The 12 months free offer is not available to customers who sign up directly for pay as you go in China and India
  • Customers who try Azure free must move to pay as you go within 30 days to keep receiving the 12 months of free services
  • Free services are capped at specified monthly amounts, and only some of them are always free
