Keeping Envoy Gateway On, Even When Bad Things Happen

This conference talk explores high availability strategies implemented in Envoy Gateway, the control plane for managing Envoy Proxy fleets. Discover how Platform Engineers and SREs can maintain system availability during failures through detailed explanations of mechanisms including Leader Election, Active-Passive Failover for Auxiliary Control Plane Services (such as External Authorization), and Panic Recovery. Gain actionable insights into architecture and operational practices that enable systems to remain reliable and performant even under challenging conditions. The presenters, Arko Dasgupta from Tetrate and Alexander Volchok from SAP, share fault-tolerance techniques essential for maintaining a resilient control plane in cloud native environments.
