Envoy Filters - Powering Effortless Observability at Scale

Learn how to implement scalable observability solutions using Envoy proxy filters in this 20-minute conference talk from CNCF. Discover Pinterest's approach to developing an Envoy ZooKeeper proxy filter that processes 250,000 requests per second across more than 100 ensembles, enabling real-time metrics, reliability tracking, and operational visibility without disrupting critical infrastructure or requiring service code modifications or redeployments. Explore how this methodology extends to both Layer 4 and Layer 7 protocols, including gRPC and Thrift, and understand how Envoy filters can serve as powerful observability tools in high-scale production environments. Gain insights into achieving low-friction observability improvements and service reliability tracking at enterprise scale through practical implementation strategies and real-world use cases from Microsoft and Pinterest engineers.
