The short version

  • Each has a real cost: Rancher another platform to run and keep available, and an outage in it affects access to everything it manages; Vault vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • They diverge on capability: Rancher covers Multi-cluster management, Vault covers Secrets management.

Where each one falls short

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

Rancher

  • Another platform to run and keep available, and an outage in it affects access to everything it manages
  • Meaningful overhead if you only operate one or two clusters
  • Version compatibility between Rancher and managed Kubernetes versions needs watching during upgrades
  • Support requires a SUSE subscription; the project itself is community-supported

Vault

  • Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
  • Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
  • Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
  • A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
