Cloud Service Mesh Adds EnvoyFilter Support and API Status Codes
Managed Cloud Service Mesh now supports a limited EnvoyFilter API implementation via the TRAFFIC_DIRECTOR, enabling advanced features like local rate limiting for data planes. Additionally, it can report status codes for Istio API acceptance or rejection, visible on resource and mesh state. These updates primarily benefit engineers and architects managing service meshes, providing greater control and visibility.
