This post is aimed at engineers who are already familiar with microservices, Kubernetes, AWS, Amazon EKS.
With increasing microservices deployment on Kubernetes, Businesses will require a method of centralizing the discovery, management, and security of services independent of language, domain, or deployment model. This is the point where a service mesh comes into the picture.
A service mesh is a dedicated infrastructure layer that you can add to your applications. It allows you to transparently add capabilities like observability, traffic management, and security, without adding them to code. The primary goal here is to have service-to-service communication in a secure, fast, and reliable fashion.
In the above architecture, microservices frontend backend and Postgres interact with each other through envoy sidecar proxy.
For the implementation, we are going to leverage Amazon EKS, AWS APP mesh.
Amazon EKS is a managed service used to run Kubernetes on AWS without any necessity for installation, operation, and maintenance for your own Kubernetes control plane or nodes.
AWS App Mesh helps to connect services, monitor the application’s network, and control the traffic flow. App Mesh standardizes how services communicate, giving end-to-end visibility and helping to ensure the high availability of your applications.
The App Mesh gives you consistent visibility and network traffic controls for every service in an application.
The below architecture depicts a high-level representation of a sample application with integration on app mesh on EKS.
We are going to create AWS App Mesh components and deploy them using a sample application. After placing the sample app into a service mesh.
Application components include:
To create the App Mesh resources and add the application into a Mesh, we need to install the AWS App Mesh Controller. This controller allows configuring App Mesh resources using kubectl. Once completed, the resulting setup looks as follows:
The above architecture diagram details the step-by-step procedure of implementing Meshify the application.
