1. Building a blazing fast gRPC Service with PHP Daniel Lienert, 28.04.2023
2. Agenda 1. Motivation 2. What are gRPC and Protocol Buffers? 3. PHP as gRPC Server? 4. gRPC in Action (code examples included)
4. Invoicing Analytics Project Management
6. Local Function Call vs. Remote Procedure Call (RPC) 6 Server A Login Server B User Management Process Login User Management Local function call Remote procedure call (RPC)
8. gRPC Performance HTTP/2 Bene fi ts of HTTP/2 Multiplexing Streams Binary protocol Server push
9. Flow Types 9 Unary Client Server Server Streaming Client Server Client Streaming Client Server Bi-drectional Streaming Client Server
10. Official libraries 10
11. gRPC vs SOAP (and REST) 11 Protocol Bene fi ts Drawbacks gRPC - High performant - Multiplexing - Binary protocol - smaller and faster - Stream processing - API oriented (no constraints) - Limited tooling and documentation compared to REST and SOAP - Requires HTTP/2 support SOAP - Established and widely adopted - Tooling and documentation available - API oriented (no constraints) - Bulky Text-based protocol slow and ine ff i cient - Complex and verbose syntax - Request / Response only - Heavyweight REST - Widely adopted and established - Simple and easy to use - Tooling and documentation available - Text-based protocol slower and less e ff i cient - Request / Response only - Requires additional e f fort for error handling - CRUD oriented
12. gRPC Use Cases • Microservices • Cloud Native Applications • High-performance APIs • IoT and Mobile Applications • Inter-service communication • Real time communication 12
13. 13 What about web?
14. 14 gRPC Web Browser gRPC WebApp Proxy Envoy Server gRPC Server HTTP HTTP/2
16. gRPC Server gRPC Client Stub Protocol Buffers
17. • Data is fully typed • Data efficient binary format • Encoding / decoding data is fast • Data can be read across any language • Embedded Documentation • Safe Schema Evolution protobuf Advantages
18. User Message De fi nition
19. Documentation pseudomuto/protoc-gen-doc
20. Evolve messages / Add fi eld
21. Evolve messages / Remove fi eld
22. Evolve messages / Remove fi eld
23. User Message De fi nition
24. Additional De fi nitions
25. Service De fi nition
27. Roadrunner
29. Initialization Common Libraries User Libraries Cache Warmup Entry Point Routing Domain Logic Response Return and Exit Classic Request Lifecycle Con fi guration Bootstrapping Actual Work Roadrunner handled requests
