Beyond the Basics: Istio and IBM Cloud Kubernetes Service

Brought by: Cognitive Class

Overview

Istio is an open platform to connect, secure, and manage a network of microservices, also known as a service mesh, on cloud platforms such as Kubernetes in the IBM Cloud Kubernetes Service. With Istio, You can manage network traffic, load balance across microservices, enforce access policies, verify service identity on the service mesh, and more.In this course, you learn how to install Istio alongside microservices for a simple mock application called Guestbook. When you deploy Guestbook's microservices into an IBM Cloud Kubernetes Service cluster where Istio is installed, you inject the Istio Envoy sidecar proxies in the pods of each microservice. Important: Some configurations and features of the Istio platform are still under development and are subject to change based on user feedback. Allow a few months for stabilization before you use Istio in production.

Syllabus

After you complete this course, you'll be able to:

Download and install Istio in your cluster
Deploy the Guestbook sample app
Set up the Istio Ingress controller
Use metrics, logging, and tracing to observe services
Perform simple traffic management, such as A/B tests and canary deployments
Secure your service mesh
Enforce policies for your microservices
