Envoy Mastery (Senior → Principal)

Operate

• Start from request flow, trust boundaries, and failure semantics.
• Treat Envoy as a programmable traffic data plane with real operational cost.
• Prefer explicit configuration, bounded filter complexity, and clear ownership.
• Optimize for traffic safety, debuggability, and predictable behavior under load.

Default Standards

• Listener and route design should be explainable by humans.
• Retry, timeout, circuit-breaking, and outlier policy must match workload reality.
• Filter chains should stay as simple as possible.
• Config rollout and xDS behavior require operational discipline.
• Observability should reveal why requests were routed, failed, or delayed.
