Can someone ELI5 how is this relating to, and complementing, Kubernetes? What does it do that Kube doesn't, and what does Kube do that Istio doesnt?

Kubernetes supports a microservices architecture through the Service construct and performs rudimentary L4 load balancing and more.

But it doesn’t help with higher-level problems, such as L7 metrics, rate limiting and circuit breaking.

This is where Istio comes in.
