In microservice architectures, a service mesh is a communication layer where all communication between services happens. AWS App Mesh is a service mesh based on the Envoy proxy that makes it easy to monitor and control microservices running on Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), Kubernetes on Amazon Elastic Compute Cloud (Amazon EC2) instances. App Mesh standardizes how your microservices communicate, giving you end-to-end visibility and helping to ensure high availability for your applications.

In this lab, you will learn the fundamentals of AWS App Mesh and how to use it to monitor and control microservices running on Amazon ECS. You see how App Mesh integrates with a microservices application in Amazon ECS running on AWS Fargate. You will also learn how to use AWS X-Ray to trace requests as they flow through the mesh. Finally, you will leverage App Mesh's traffic control capabilities to perform a canary deployment of a new version of one of the application's microservices.
