Pick Linkerd when

Kubernetes teams with many microservices
Security teams wanting zero-code mTLS
Platform teams avoiding Istio complexity
Ops teams cutting incident time and costs

When Linkerd is not a fit

Teams not on Kubernetes; Linkerd meshes Kubernetes services only
Small clusters with a handful of services; a mesh is overkill
Anyone expecting a free production-grade release; stable channel now costs money
Buyers who need published pricing before talking to sales
