Istio – An open platform to connect, manage, and secure microservices
Can somebody explain what istio does in simple words?I see that it hooks into micro/services communication, but why do we need that? isnt policies enforced by cni plugins? and can microservices communicate already with k8s and mesos default setups?is istio an network abstraction layer for k8s and mesos? why would anyone want that, is there anybody who changes scheduling runtimes often?
