Safer Service-To-Service Communications. Also, keep in mind, that some of the services we use have not been built in-house, so Istio allows us to “spy” on these black boxes, by capturing and recording data points surrounding the ingress and egress. It’s a collection of components that extend Kubernetes. What's the difference between Freeway and Highway? All freeways are highways, but not every highway is a freeway. A service mesh is a dedicated infrastructure layer for handling service-to-service communication. The specification describes a set of ports that should be exposed, the type of protocol to use, SNI configuration for the load balancer, etc. Setup Istio by following the instructions in the Installation.
