Introducing AWS App Mesh, a managed service mesh to facilitate easy inter-service communication among microservices.
Agenda includes definitions and features of service meshes, microservice architecture, and their communication protocols.
Service mesh definition, its infrastructure layer role in service-to-service communication, and Envoy proxy usage.
Goals of control plane, proxy configuration difficulties, and applications of observability to improve troubleshooting.
Highlights on AWS integrations, service discovery, region availability, and preview vs GA capabilities.
Demo showcasing traffic routing in AWS App Mesh with two services: color-gateway and color-teller.
Color-teller service functions, environment variable configurations, traffic routing, and mesh components.
Details on Virtual Nodes, their service discovery roles, listeners, and how virtual routers handle traffic routing.
Traffic management through routes, defining request handling processes, and service version updates in routing.
Summary of app mesh architecture and functionalities, plus links to AWS resources and documentation.

Service Mesh A service mesh is a dedicated infrastructure layer for handling service-to-service communication. It’s responsible for the reliable delivery of requests through the complex topology of services that comprise a modern, cloud native application. In practice, the service mesh is typically implemented as an array of lightweight network proxies that are deployed alongside application code, without the application needing to be aware. - Linkerd CEO William Morgan
