Microservice practitioners on the ground soon discover that most operational issues encountered during the transition to a distributed architecture primarily stem from two key factors: networking and observability. The challenge of networking and troubleshooting a complex array of interconnected distributed services is significantly more daunting than doing so for a singular monolithic application. Envoy acts as a high-performance, self-contained server that boasts a minimal memory footprint and can seamlessly operate alongside any programming language or framework. It offers sophisticated load balancing capabilities, such as automatic retries, circuit breaking, global rate limiting, and request shadowing, in addition to zone local load balancing. Furthermore, Envoy supplies comprehensive APIs that facilitate dynamic management of its configurations, enabling users to adapt to changing needs. This flexibility and power make Envoy an invaluable asset for any microservices architecture.
