Course description
Introduction to Istio
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. LFS144x 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.
This course begins with an overview of service meshes in general and Istio in particular. We describe 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.

Prerequisites
Before starting this course, you should be familiar with:
- Basic Linux concepts and command line
- Knowledge of Kubernetes fundamentals and Kubernetes CLI - we recommend Introduction to Kubernetes, free on edX
- For hands-on lab exercise, access to a Kubernetes cluster is required. Lab exercises in this course have been tested in a GCP environment.
Outcome / Qualification etc.
What you'll learn
After completing this course, you will gain an understanding of the architecture and components of the Istio service mesh, and be able to do the following:
- Install Istio on a Kubernetes cluster
- Configure Ingress
- Understand how sidecar injection works
- Monitor your services using Grafana, Zipkin, and Kiali
- Route traffic between multiple service versions
- Perform blue-green and canary deployments
- Inject failures and use resiliency features
- Understand the concept of workload identity and “zero trust” architectures
- Control access to your workloads
- Extend the Istio mesh functionality using WebAssembly
