app-mesher

A sample architecture incorporating AWS App Mesh as a service mesh for services that communicate via gRPC.

Setup

Get started with the /infra README file.

Verify

1. Verify the API with the following request:

curl -X POST \
https://mesher.example.com/client/v1/tokens \
-d '{"id": 123, "username": "mesher"}'

{
  "token": "token:mesher",
  "profile": "profile:123",
  "data": "data:123"
}

2. Verify the deployment on the AWS dashboard:

• View the service mesh on App Mesh
• View the service map on X-Ray
• View the private DNS namespace used for service discovery on Cloud Map
• View the ECS cluster and services on ECS

Next Steps

• Configure tracing
• Investigate retry policies and circuit breaker settings
