AWS App Mesh

Introduction

App Mesh makes it easy to run microservices by providing consistent visibility and network traffic controls for every microservice in an application. App Mesh separates the logic needed for monitoring and controlling communications into a proxy that runs next to every microservice. App Mesh removes the need to coordinate across teams or update application code to change how monitoring data is collected or traffic is routed. This allows you to quickly pinpoint the exact location of errors and automatically re-route network traffic when there are failures or when code changes need to be deployed.

You can use App Mesh with AWS Fargate, Amazon Elastic Container Service (ECS), Amazon Elastic Container Service for Kubernetes (EKS), and Kubernetes on EC2 to better run containerized microservices at scale. App Mesh uses Envoy, an open source proxy, making it compatible with a wide range of AWS partner and open source tools for monitoring microservices.

Availability

Today, AWS App Mesh is generally available for production use. You can use App Mesh with AWS Fargate, Amazon Elastic Container Service (ECS), Amazon Elastic Container Service for Kubernetes (EKS), applications running on Amazon EC2, and Kubernetes on EC2 to better run containerized microservices at scale. App Mesh uses Envoy, an open source proxy, making it compatible with a wide range of AWS partner and open source tools for monitoring microservices.

Getting started

For help getting started with App Mesh, take a look at the examples in this repo.

China Regions

All the examples and walkthrough are written for commercial regions. You need to make few changes to make them work for China regions, below are some changes that will be needed:

• Change ARN:For China regions include aws-cn in all arns. So instead of 'arn:aws:' it starts with 'arn:aws-cn:'.Replace 'arn:aws:' with 'arn:${AWS::Partition}:' to make it work for all partitions.
• Change Endpoints:The endpoint domain for China regions is amazonaws.com.cn. Replace the endpoints from amazonaws.com to amazonaws.com.cn Refer this doc for a list of endpoints for cn-north-1.Do not change the Service Principal like ecs-tasks.amazonaws.com, it is a Service Principal not an endpoint.
• Change TCP ports 80/8080/443By default all AWS China accounts are blocked for TCP ports 80/8080/443 with EC2 and S3 services. These ports will be unlocked when an ICP license has been provided by customers. As a workaround you can use some other port for ex: 9090. The url that you curl for, needs to explicitly mention the port now.For example: http://appme-.....us-west-2.elb.amazonaws.com.cn:9090/color

Why use App Mesh?

1. Streamline operations by offloading communication management logic from application code and libraries into configurable infrastructure.
2. Reduce troubleshooting time required by having end-to-end visibility into service-level logs, metrics and traces across your application.
3. Easily roll out of new code by dynamically configuring routes to new application versions.
4. Ensure high-availability with custom routing rules that help ensure every service is highly available during deployments, after failures, and as your application scales.
5. Manage all service to service traffic using one set of APIs regardless of how the services are implemented.

What makes AWS App Mesh unique?

AWS App Mesh is built in direct response to our customers needs implementing a 'service mesh' for their applications. Our customers asked us to:

• Make it easy to manage microservices deployed across accounts, clusters, container orchestration tools, and compute services with simple and consistent abstractions.
• Minimize the cognitive and operational overhead in running a microservices application and handling its monitoring and traffic control.
• Remove the need to build or operate a control plane for service mesh.
• Use open source software to allow extension to new tools and different use cases.

In order to best meet the needs of our customers, we have invested into building a service that includes a control plane and API that follows the AWS best practices. Specifically, App Mesh:

• Is an AWS managed service that works across container services with a design that allows us to add support for other computer services in the future.
• Works with the open source Envoy proxy
• Is designed to pluggable and will support bringing your own Envoy images and Istio Mixer in the future.
• Implemented as a multi-tenant control plane to be scalable, robust, cost-effective, and efficient.
• Built to work independently of any particular container orchestration system. Today, App Mesh works with both Kubernetes and Amazon ECS.
