Choose Ansible if:
Teams automating server configuration without adopting a full orchestration platform.
Choose Keycloak if:
Organisations that need enterprise identity without a per-user bill.
Ansible: pros & cons
- No agent required on managed hosts
- Playbooks are readable by people who did not write them
- Huge collection of community modules
- Slow on very large fleets
- YAML becomes unwieldy as logic grows
- Idempotency depends on the module doing it properly
Keycloak: pros & cons
- Full identity server at no licence cost
- Standards support including SAML and OIDC
- Complete control over user data
- Operating it is a real responsibility
- Administration console is dense
- Upgrades need care
Our verdict on Ansible
The easiest configuration tool to start with. Once playbooks contain real logic, you are programming in YAML and it shows.
Our verdict on Keycloak
The serious open-source answer to Auth0. Budget for the operations, because the licence saving is not free.
