Linkerd: The Lightweight Service Mesh
Shriira Press
A service mesh that gets out of your way — automatic mTLS, golden metrics, and reliability with a tiny, fast footprint.
Welcome to Linkerd: The Lightweight Service Mesh.
Linkerd is the lightweight service mesh for Kubernetes, built around simplicity: it adds security, reliability, and observability to service-to-service communication with a famously small, fast, easy-to-operate footprint, using a purpose-built Rust micro-proxy instead of a general-purpose one. This free book teaches it from the ground up: the service-mesh model and Linkerd's minimalist philosophy, its architecture (control plane and the Rust micro-proxy), proxy injection, automatic mutual TLS and security (zero-config zero-trust), observability with golden metrics and live tap, reliability with smart latency-aware load balancing and retries, traffic management and progressive delivery (with Flagger), multi-cluster and the extension model, and operating Linkerd in production (including the trust-anchor and certificate lifecycle). Ten focused chapters with clear diagrams that show how to get a service mesh's core value without the mesh tax.
