Explore context-aware traffic routing for stateful services using Envoy in this conference talk by Renana Yacobi and Piaw Na from Niantic. Learn how to implement invisible service infrastructure for application APIs, addressing challenges related to sensitive information like PII and company IP. Discover techniques for routing decisions based on message content, including the use of Envoy custom filters and partial message parsing. Gain insights into retrofitting protocols, performing smarter routing, and improving performance through client-server mapping coordination. Examine load test setups, resource utilization, and the benefits of partial message deserialization for large messages.
