Application or API needs to have the most basic identity authentication mechanism, and the enterprise-level management system needs to implement functions such as Identity management, single sign-on, and security policy settings. Keycloak is an identity and access management (IAM) solution that can be easily deployed on the Kubernetes platform to provide applications and APIs with features such as centralized authentication. This speech will explain that our cloud native management platform makes full use of the powerful and comprehensive features of Keycloak to implement enterprise-level identity and security access management functions, and we also create some plugins, making appropriate expansions in the aspect of IDP and Event functions to play Keycloak to the greatest extent.
