Introduction to Istio (LFS144)

This course is a practical introduction to Istio, designed for anyone who wishes to build on their knowledge of Linux, Docker, and Kubernetes to learn how to install and configure a service mesh and to understand the benefits of deploying and running distributed applications in a service mesh environment.

Who Is It For

This course is intended for application developers, systems operators, and security professionals who already have familiarity and experience with Kubernetes and who wish to take their first steps towards learning and understanding Istio.

What You’ll Learn

This course begins with an overview of service meshes in general and Istio in particular. You will learn what problems service meshes solve, and explain Istio's architecture, how Istio functions, and how the environment around a deployed application is configured to allow the application to join the mesh. Through the course's lessons and labs, you will experience and learn how Istio facilitates system observability by collecting and publishing metrics and allows you to control how traffic is routed to your application. Learn how Istio supports canary deployments and other scenarios and makes your distributed applications more resilient through retries, timeouts, and circuit breakers. The final chapter covers more advanced topics, including onboarding workloads running on VMs (outside of Kubernetes) and how Istio provides for extensibility through WebAssembly plugins.

What It Prepares You For

This course will prepare you to work with Istio as a developer whose applications are deployed to an Istio service mesh or as a service mesh operator with responsibilities for installing, upgrading, and configuring Istio as a security professional responsible for defining ingress, egress, authentication and authorization policies with Istio. You will develop an understanding of the concepts and, through the labs, have the chance to practice common scenarios, including installing Istio, deploying applications to the mesh, monitoring applications, configuring traffic management, including ingress, and applying security policies.

Before starting this course, you should be familiar with:

  • Basic Linux concepts and command line
  • Knowledge of Kubernetes fundamentals and Kubernetes CLI – we recommend the free Introduction to Kubernetes course.

For hands-on lab exercises, access to a Kubernetes cluster is required. Lab exercises in this course have been tested in a GCP environment.

If using a cloud provider like GCP, AWS, or Azure, you should be able to complete the lab exercises using the free tier or credits provided to you. However, you may incur charges if you exceed the credits initially allocated by the cloud provider.
