What capabilities does Envoy provide for gRPC support?

Envoy’s capabilities for gRPC support include offering efficient handling of binary protocols along with advanced load balancing features. This is essential as gRPC is designed to use HTTP/2, which allows for efficient transport of binary data, thereby enhancing performance for microservices interactions.

Envoy acts as a gateway that can translate HTTP/1.x traffic into HTTP/2, enabling seamless interactions between different microservices while maintaining strong performance. Its support for load balancing is particularly important in a microservices architecture, where requests can be directed to multiple instances of services dynamically based on various strategies. This includes round-robin, least connections, and circuit breaking, ensuring a more resilient and responsive application.

While other options touch on aspects related to gRPC, they do not fully capture the core strengths of Envoy regarding its handling of binary protocols and load balancing, which makes it highly suitable for gRPC workloads.
