Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Ansible
- The open source project gives the engine and the language; the automation controller, automation mesh, automation hub, analytics and governance all belong to the paid Red Hat Ansible Automation Platform
- Event-Driven Ansible and the AI coding assistant are platform features rather than open source ones
- Red Hat does not publish platform pricing
- Running open source Ansible at scale means building the control plane the platform otherwise provides
Keycloak
- Requires self-hosted deployment and operational expertise to install, configure and maintain
- No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
- Clustering and high-availability configurations require additional operational knowledge
- Community support only; commercial support requires third-party vendors or distributions
