Overview
Linkerd is a service mesh designed for simplicity and performance. It provides critical features like observability, reliability, and security without the complexity of larger service meshes like Istio.
Key Features
- Zero Config: Works out of the box with minimal configuration.
- Mutual TLS (mTLS): Automatically secures all service-to-service communication with encryption and identity verification.
- Observability: Provides 'golden metrics' (success rate, latency, throughput) for every service.
- Reliability: Includes features like retries, timeouts, and load balancing.
Philosophy
Linkerd focuses on being 'ultralight' and 'transparent,' aiming to be as easy to operate as possible for Kubernetes users.
