Dynamic Modules - A New Era of High-Performance Envoy Extensions

Learn about dynamic modules as a revolutionary extension mechanism for Envoy proxy in this conference talk from CNCF. Discover how dynamic modules function as shared libraries that can be loaded by Envoy at runtime, providing a high-performance alternative to existing extension mechanisms like Lua, External Processing, or Wasm. Explore benchmark results demonstrating that dynamic modules achieve nearly identical performance to native C++ extensions while eliminating the need to rebuild Envoy binaries and reducing maintenance overhead. Understand how this feature enables development in multiple programming languages, making it particularly valuable for vendors and end users requiring performance-sensitive custom business logic with minimal maintenance requirements. Gain insights into recent updates and future developments from the maintainer of dynamic module support in Envoy, and see how this advancement addresses a long-awaited need within the Envoy community for efficient, flexible extension capabilities.
