KubeCon + CloudNativeCon North America 2024

A single sign on solution for your customers and employees should be designed for high availability without a single point of failure. Keycloak is no exception to this. A clustered Keycloak deployment in a single site provides sufficient availability for many. An increasing number of organizations need to utilize multiple sites for improved resiliency or to meet legal requirements. Keycloak overhauled its capabilities and now provides deployment blueprints to the community. This talk presents how we approached the problem, and the challenges we faced. Expect to dive into concepts like load shedding, cache stampedes, and automated failover. See tools like Gatling, Helm, OpenTelemetry, Kubernetes Operators and cloud infrastructure in action. We will also provide an outlook for the next steps in our journey. These insights will help you to improve your Keycloak deployments as well as design and test your own applications so they can withstand high load and site failures.
