Istio

Get started with an exciting Kubernetes "Service Mesh"
  • This course aims to make Istio understandable, and will demonstrate the massive benefits a service mesh can bring to a live Kubernetes cluster.
  • Run Istio locally and try out its features using Minikube.
  • Traffic Management, Telemetry, Distributed Tracing, Security and Fault Tolerance are all explained in detail.

Pre-requisites

Prior experience with Kubernetes is assumed. The course uses Minikube, but you will need sufficient RAM to be able to allocate 4Gb (eg 8Gb Host RAM should be sufficient).

Contents - The course is around 11 hours, with lots of hands on demos.
