Why Linkerd?

Smaller and faster than any other mesh

Smaller and faster than any other mesh
Benchmarks show that Linkerd continues to be dramatically faster than Istio while consuming just a fraction of the system resources.

Designed for simplicity and security

I absolutely love @Linkerd - among other things it makes load balancing of grpc service trivial. #Kubernetes.

A year ago I switched from Istio to @Linkerd. Ever since then I never had this “…oh maybe that issue is caused by our service mesh” feeling again.

In few hours we are able to tap in our production and staging applications logs thanks to @Linkerd, wonderful slack support also available, solved one issue came in while injecting @Linkerd, it will help our team to see it before client share with us
