Envoy

Envoy is a software tool designed to improve the performance and reliability of internet applications, particularly in microservices architectures. It acts as a proxy, handling incoming and outgoing traffic between services, which helps manage communication, security, and data flow. By offering features such as load balancing, monitoring, and fault tolerance, Envoy enhances how services interact, ensuring they can scale efficiently and remain robust. Originally developed at Lyft, it's now widely used in the tech industry to optimize the infrastructure of cloud-based applications.
