 High availability (HA) is a system design approach that ensures a service remains continuously accessible, even during failures of individual components, by eliminating single points of failure. It introduces redundancy and failover mechanisms to minimize downtime and maintain operational continuity.
 
-{product} supports HA deployments on {ocp-brand-name} and {aks-name}. The HA deployments enable more resilient and reliable service availability across supported environments.
+{product} supports HA deployments on the following platforms:

+* {eks-name}
+
+The HA deployments enable more resilient and reliable service availability across supported environments.
 
 In a single instance deployment, if a failure occurs, whether due to software crashes, hardware issues, or other unexpected disruptions, it would make the entire service unavailable, interrupting development workflows and access to key resources.
