6. Architecture Run Tasks Pub/Sub Mobile App External Service Mobile API Web Hook API Job API Scheduler
7. What is Cloud Run Cloud Run is a managed compute platform that enables you to run containers that are invocable via requests or events. Cloud Run is serverless: it abstracts away all infrastructure management... https://cloud.google.com/run/docs
8. Architecture - Key Concepts - ɾEverything runs on Cloud Run ɾEverything runs as a API (gRPC)
9. Architecture Run Tasks Pub/Sub Mobile App External Service Mobile API Web Hook API Job API Scheduler
10. Architecture Run Tasks Pub/Sub Mobile App External Service Mobile API Web Hook API Job API Scheduler
11. Architecture - Key Concepts - e.g.) VS. Cloud Functions Trigger Run Pub/Sub Functions Run Firestore Functions
12. Architecture Run Tasks Pub/Sub Mobile App External Service Mobile API Web Hook API Job API Scheduler
13. Architecture ✅ Everything is Managed as API De fi nitions ✅ Reuse same implementation logic as APIs ✅ Use same Monitoring environments
14. Architecture ✅ Everything is Managed as API De fi nitions ✅ Reuse same implementation logic as APIs ✅ Use same Monitoring environments
15. gRPC gRPC is a modern open source high performance Remote Procedure Call (RPC) framework that can run in any environment. https://grpc.io/
16. gRPC 🧑💻
17. Architecture: 2020 ~ Run Customer App Customer gRPC
18. Architecture: 2021 ~ Run Customer App Customer gRPC / Partner gRPC Partner App
19. Modular Monolith Almost all the cases where I've heard of a system that was built as a microservice system from scratch, it has ended up in serious trouble. ... you shouldn't start a new project with microservices, even if you're sure your application will be big enough to make it worthwhile. MonolithFirst Martin Fowler https://martinfowler.com/bliki/MonolithFirst.html
20. Modular Monolith ✅ Pros - Single Deployment Unit - Simple Design ❌ Cons - Independence - Autonomy
21. Architecture: 2022 ~ Run Customer App Customer gRPC Partner App Partner gRPC
22. API Gateway Pattern Customer App Customer gRPC Partner App Partner gRPC API Gateway
23. O ffl oading Cross-Cutting Concerns to the API Gateway ✓ Authentication / Authorization ✓ Transcoding ✓ Being Internet facing (TLS / Domain / CDN / IP ...) ✓ ...
24. API Gateway Pattern Customer App Customer gRPC Partner App Partner gRPC Envoy (API Gateway)
25. Envoy https://www.envoyproxy.io/docs/envoy/v1.23.0/intro/what_is_envoy Envoy is an L7 proxy and communication bus designed for large modern service oriented architectures. The project was born out of the belief that:ɹ The network should be transparent to applications. When network and application problems do occur it should be easy to determine the source of the problem.
26. Why Envoy? • Extensibility with WebAssembly • Dynamic Con fi gurations • Widely used in the Cloud Native World

35. from Single Service
36. to Microservices
37. Access Control
38. Access Control - Cloud Run - • Access Control with IAM • Restricting Ingress
39. Access Control with IAM
