Envoy Rate Limit

Envoy Rate Limit Service is an open-source, distributed rate limiting service designed to work with Envoy Proxy. It provides centralized API rate limiting through a gRPC-based service and uses Redis to manage rate limit counters. It helps control API traffic, enforce request quotas, protect backend services from excessive requests, and support scalable microservices and cloud-native applications.

• Provide centralized and distributed rate limiting for Envoy-based applications.
• Enforce configurable API request limits and quotas.
• Use Redis for storing and managing distributed rate limit counters.
• Support scalable microservices and cloud-native application architectures.
• Help protect backend services from excessive API traffic.
• Integrate with Envoy Proxy through a gRPC-based rate limit service.
• Support configurable rate limit policies and request descriptors.

$ Verify the installed version:
$ git describe --tags --exact-match

$ Verify the Rate Limit Service:
$ systemctl status ratelimit --no-pager

$ Check Redis:
$ systemctl status redis-server --no-pager
$ redis-cli ping
