Discussion

Envoy client connections must be limited to preserve system resources and continue servicing connections without interruption. Without a limit set, the system would be vulnerable to a trivial denial-of-service attack where connections are created en masse and vCenter resources are entirely consumed. Envoy comes hard coded with a tested and supported value for "maxHttpsConnections" that must be verified and maintained.
