Where each one falls short

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

Terragrunt

  • Additional complexity layer on top of Terraform
  • Requires understanding of Terraform concepts
  • Paid tier pricing not clearly published
