+A single sign on solution for your customers and employees shouldn't be a single-point-of-failure in your architecture.
+At Devoxx France 2024, Ryan Emerson and Alexander Schwartz presented, from an architects and developer perspective, how Keycloak approached the problem.
+They describe which architecture the Keycloak team chose, the challenges they faced and which tools helped along the way.
+The slides and the recorded video are linked below.
+Scroll down for additional links and details of the tasks we're currently working on to further enhance the architecture.

+A clustered Keycloak deployment in a single site or datacenter provides sufficient availability for many.
+However, an increasing number of organizations need to utilize multiple sites for improved resiliency or to meet legal requirements.
+In 2023, Keycloak overhauled its multi-site capabilities for public and private cloud infrastructures, tested them thoroughly and provided deployment blueprints to the community.
+As part of the release of Keycloak 24, an active/passive setup is now fully supported.
+
+Read more about it in the new https://www.keycloak.org/high-availability/introduction[high availability guide] published as part of https://www.keycloak.org/documentation[Keycloak’s documentation], and get more tools and background information in the https://github.com/keycloak/keycloak-benchmark[Keycloak Benchmark Project].
+Since the https://www.keycloak.org/2023/12/recover-site-failures.html[previous blog post] which covered Keycloak 23, we have made the configuration of such a setup simpler, with fewer options required by Keycloak and the Keycloak Operator.
+Thank you to everyone who provided feedback along the way, and those who participated in our survey in early 2023 which guided us in the implementation of this setup.
+
+Still, the journey doesn't stop here: The team is now working on https://github.com/keycloak/keycloak/discussions/28271[durable sessions across restarts and upgrades], and a
+https://github.com/keycloak/keycloak/issues/28745[simpler Infinispan architecture which aims to eventually support active/active].
+Follow these issues and discussions to stay up-to-date with the latest developments, and provide feedback on Keycloak’s nightly builds.
