AWS App Mesh AWS lab

 AWS App Mesh is a service mesh that provides application-level networking for microservices-based applications. It makes it easy to discover, route, and monitor traffic between your services.

1. Prerequisites

• An AWS account
• An Amazon Elastic Kubernetes Service (EKS) cluster
• A deployed microservices application

2. Create an App Mesh

• Navigate to App Mesh:
  In the AWS Management Console, search for "App Mesh" and select the service.
• Create a new mesh: Click on "Create mesh".
• Provide details: Give your mesh a name and description.
• Choose a mesh type: For this lab, select "Virtual Node".
• Create the mesh: Click "Create".

3. Create a Virtual Node

• Select your mesh: Click on the mesh you just created.
• Create a virtual node: Click on "Create virtual node".
• Provide details: Give your virtual node a name and description.
• Choose a namespace: Select the namespace where your microservice is running.
• Configure the port mapping: Specify the port on which your service is listening.
• Create the virtual node: Click "Create".

4. Deploy the App Mesh Sidecar

• Update your deployment: Modify your Kubernetes deployment manifest to include the App Mesh sidecar.
• Deploy the updated manifest: Use kubectl apply to deploy the updated manifest.

5. Test Your Application

• Access your application: Try to access your application. The App Mesh sidecar will handle traffic routing and management.
• Monitor metrics: Use AWS CloudWatch to monitor metrics related to your application and App Mesh.

Additional Steps

• Create virtual routers and routes: If you have multiple microservices, you can create virtual routers and routes to control traffic flow.
• Configure fault tolerance: Use App Mesh to implement fault tolerance mechanisms like retries and timeouts.
• Integrate with other AWS services: App Mesh can be integrated with other AWS services like X-Ray for distributed tracing and AWS WAF for web application firewall.
