gRPC Microservice Communication with AWS AppMesh

This session was conducted at the AWS Colombo User Group July Session. Here I talked about Microservice communication with gRPC in AWS App Mesh.

Transcript

1. Agenda • Microservice Communication & It’s Challenges • What is gRPC & how it works ? • AWS App Mesh • Demo
2. The Big Monolith
3. The Big Monolith
4. Micro-Services Today
5. Challenges Managing Communication
6. Managing Communication • Managing API Contracts • Overhead to Write Client Code • Performance Issues with sending JSON over the http
7. Challenges Managing Communication Service Discovery
8. Service Discovery 172.31.1.10/16 172.31.1.10/16 172.31.2.20/16
9. Challenges Managing Communication Service Discovery Observability & Resilience
10. Observability & Resilience • Tracking failures in up-stream services • Application performance monitoring of up-stream services • Resilience - Retries, Circuit breaker pattern etc..
11. What is gRPC ? • Inter-Process communication technology • Binary messaging format on top of Http/2 (Protobuf) • Invoke remote methods like a local function call • Contract first approach • Polyglot
12. gRPC Contract (.proto) Inventory_manager.proto
13. gRCP Client & Server Inventory_manager.proto Client (C# .Netcore) Server (C# .Netcore)
14. gRPC vs HTTP API’s Source – Microsoft Docs
15. What is AWS App Mesh ? • Managed Service Mesh for application-level networking • End to end visibility/observability support for Microservices • Traffic Management Capabilities (Http2, gRPC) • Hybrid deployments
16. AWS App Mesh
17. Sidecar Pattern
18. Concepts • Service Mesh - A logical boundary for network traffic between the services that reside within it • Virtual Service - is an abstraction of an actual service that is provided by a virtual node, directly or indirectly, by means of a virtual router. • Virtual Node - acts as a logical pointer to a discoverable service, such as an Amazon ECS service • Virtual Router & Routes - Virtual routers handle traffic for one or more virtual services within your mesh • Virtual Gateway – allows resources outside your mesh to communicate with services inside the mesh
