🆚 Envoy vs. Varnish

Envoy is a high-performance, open-source edge and service proxy designed for cloud-native applications and large microservice "service mesh" architectures.

It provides advanced L4/L7 load balancing, HTTP/2 and gRPC proxying, service discovery integration, observability with distributed tracing and rich metrics, and dynamic configuration via xDS APIs.

Varnish Cache is an open-source HTTP accelerator and reverse caching proxy that caches content from web servers to reduce load times, and supports native TLS termination and Kubernetes deployments.

It uses the VCL configuration language compiled to native C code, serves cached responses in three system calls, provides official container images and a Helm chart for Kubernetes, outputs structured JSON logs, and supports VMOD extension modules.
