Getting started with Microservices with Istio and IBM Cloud Kubernetes Service

Discover how microservices and Istio pair together for cloud-native apps. Learn how Istio and IBM Cloud Kubernetes Service help you securely and seamlessly deploy containers and apps.

About this course
In this course, you learn about the twelve-factor app methodology, microservices, and Istio foundational technologies. These cloud-native technologies are the essentials as you build new apps for the cloud. Microservices are the building blocks for your cloud architecture. Then, you layer on Istio to help you connect, manage, and secure those microservices. All of those are then put together in IBM Cloud Kubernetes Service.

What will I get after passing this course?
You will receive a completion certificate.
