gRPC

Regular Procedure Call
RPC ?
What is gRPC ?
✔ Open source RPC framework
✔ Bandwidth & CPU efficient
✔ Low latency
✔ Way to create massively distributed systems
gRPC C Core & Wrapped Language Stack
Role of C Core?
✔ Full HTTP/2 implementation with
authentication
✔ Manages interactions with system
✔ Provides interface to wrapped-language stack
Why gRPC ?
Streaming
✔ Server-side streaming
✔ Client-side streaming
✔ Bidirectional streaming
Remote Procedure Calls
✔ RPC setup is easy
✔ All the classes related for request & response are provided
✔ Using a client = calling a function in the code

2. Regular Procedure Call class GreeterService { String SayHello(String txt); } class GreeterClient { var greeter = new GreeterService(); greeter.SayHello(“World”); }
3. RPC ? RPC Wikipedia definition RPC is a protocol that one program can use to request a service from a program located in another computer in a network without having to understand network details
4. Basic RPC MACHINE2 / SERVER class GreeterService { String SayHello(String txt); } MACHINE1 / CLIENT class GreeterClient { }
5. Questions ! 1. How does a client call a service on a remote machine ? 2. How do you expose a service on a remote machine for consumption ? 3. How data is serialized & deserialized over the wire ? 4. What is the nature of the call ? 5. Authentication
6. Choices 1. Build your own custom RPC framework 2. Use gRPC : A high performance, open- source universal RPC framework
8. What is gRPC ? ✔ Open source RPC framework ✔ Bandwidth & CPU efficient ✔ Low latency ✔ Way to create massively distributed systems
9. From Where? @ Google they use Stubby Ten billion of RPC per second
10. gRPC g?
11. gRPC g? Recursive Acronym
12. Languages C++, Objective-C, PHP, Python, Ruby Node.js, GO, C#, Java
13. gRPC C Core & Wrapped Language Stack
14. Role of C Core? ✔ Full HTTP/2 implementation with authentication ✔ Manages interactions with system ✔ Provides interface to wrapped-language stack
15. Why gRPC ? Performance HTTP / REST gRPC
16. But HOW? HTTP/2 transport protocol http://www.http2demo.io Streaming Strongly typed Use Protobuffer 3
17. Why gRPC ? Streaming ✔ Server-side streaming Client-side streaming ✔ Bidirectional streaming ✔
18. Why gRPC ? Remote Procedure Calls ✔ RPC setup is easy All the classes related for request & response are provided ✔ Using a client = calling a function in the code ✔
19. Why gRPC ? Scalable Extensible
20. Architecture
21. Getting Started… 1. Define a service in a .proto file using Protocol Buffers IDL 2. Generate server and client stub code using the protocol buffer compiler 3. Extend the generated server class & fill the logic
22. Thank you!
