Improving Performance of RPCs with Envoy at Wikimedia

Explore how Wikimedia improved the performance of remote procedure calls (RPCs) using Envoy in this informative conference talk. Discover the challenges faced when performing RPCs over high-latency networks or using TLS, especially in environments without persistent connection pools like PHP. Learn about Wikimedia's implementation of Envoy in their mixed on-premises and Kubernetes environment, and understand how this adoption enhanced performance, reliability, and observability of their stack. Gain insights into the significant performance improvements for PHP applications running at scale, the operational issues resolved by Envoy, and the new challenges introduced by its integration. Delve into practical solutions for optimizing RPCs in complex, distributed systems and understand the benefits of using modern proxy technologies in large-scale web applications.
