Linkerd

Linkerd is a lightweight Service Mesh. It focuses on simplicity and performance (Rust-based proxies). v2.15 (2025) enables Mesh Expansion to VMs.

When to Use

  • Low Overhead: You want mTLS and Metrics but can't afford Istio's CPU tax.
  • Simplicity: "It just works". No complex configuration for basic features.
  • Security: Default-on mTLS and authorization policies.

Core Concepts

Micro-Proxy

Linkerd uses a specialized Rust proxy (not Envoy) that is tiny and fast.

Viz Extension

A dashboard and Prometheus instance pre-configured to show mesh metrics (Success Rate, Latency).

ServiceProfiles

Define retry logic and timeouts per route.

Best Practices (2025)

Do:

  • Use HA Mode: Run control plane in high-availability mode for production.
  • Automate Cert Rotation: Use cert-manager to rotate the mTLS root CA automatically.
  • Expand to VMs: Use the new 2.15 feature to include legacy databases in the mesh.

Don't:

  • Don't disable mTLS: It's verified automatically. Keep it on.
