Envoy Rate Limit

Envoy Rate Limit is a service that integrates with the Envoy proxy to enforce request rate limits across APIs and microservices. It acts as a backend service that Envoy queries via gRPC to determine whether a request should be allowed or rejected based on configurable policies, such as per-user, per-service, or global limits. This helps prevent abuse, ensures fair usage, and protects services from traffic spikes or denial-of-service attacks.

Features of Envoy Rate Limit:

• Enforces request rate limits via a dedicated backend service.
• Supports fine-grained control with per-user, per-service, or global rules.
• Integrates seamlessly with Envoy proxy using gRPC.
• Scalable and suitable for distributed microservice architectures.
• Improves API reliability, security, and prevents traffic abuse.

To check the version of Envoy Rate Limit service, run the following command:

$ envoy --version

Disclaimer: Envoy Rate Limit is a backend service designed to provide scalable request limiting for microservices and APIs. Users are responsible for configuring rate limit rules, deploying the service, and integrating it with Envoy proxies securely.
