WebApplicationClass

A WebApplicationClass is a platform-level template that provides governance and standardization for WebApplication resources in OpenChoreo. It follows the Claim/Class pattern where platform teams define Classes to enforce organizational policies, resource limits, and deployment configurations while application teams create WebApplications (claims) that reference these classes.
