Our Introduction to Istio training covers using a service mesh (Istio) to control network traffic between microservices deployed on Kubernetes.

In this course you will learn how to control the flow of traffic and API calls between services, test various failure scenarios, automatically secure your services through managed authentication, authorization and encryption of communication between services, apply polices and ensure that they’re enforced, and observe everything with rich automatic tracing, monitoring and logging of all your services.

Goals

After completing this course, students will have a firm understanding on how to use a service mesh to control network traffic for their containerized application infrastructure.

  • strong grasp of container basics (recommended training: Docker Basic)
