Which HA concept applies for OAuth operations in a multi-node Kubernetes cluster?
High Availability (HA) Concept: In a multi-node Kubernetes cluster, the concept of ''Quorum'' is crucial for ensuring high availability and consistency, especially for operations like OAuth.
Quorum Definition: Quorum refers to the minimum number of nodes that must agree on a transaction or operation to ensure consistency and avoid split-brain scenarios. This is particularly important in distributed systems to maintain data integrity and availability.
OAuth Operations: For OAuth operations, maintaining a quorum ensures that the authentication and authorization processes are reliable and consistent across the cluster. This helps in preventing issues where different nodes might have conflicting states.
