Up and Running with gRPC & Cloud Career [GDG-Cloud-Dhaka-IO/2022}

1. Knowledge Sharing Session
Up and Running with gRPC
&
Could Career
Md. Sadhan Sarker

2. 1
A high performance, open source
universal RPC framework by google.
Now its part of the Cloud
Foundation (CNCF)
https://grpc.io/about/

3. 2
Understand RPC!
An RPC is a Remote Procedure Call. Google introduce gRPC, But
Common Object Request Broker Architecture (CORBA) had RPC before!
Server Code (any language)
…[code]
def function create_post(Post post) {
…
}
…[code]
Client Code (any language)
…[code]
server.createPost(post)
…[code]
RPC call
(over the network)

5. 4
When we choose gRPC?
Why gRPC?
- build microservices
- connect cross-languages services
- Build distributed services
- need client & server streaming
- http2 based transport protocol

6. 5
gRPC vs REST
Comparisons
- REST uses HTTP/1.1 protocol through the JSON or XML messaging
format. Common http verbs like {GET, POST, PUT, DELETE etc}
- gRPC uses HTTP/2 protocol through Protocol buffer. Methods
{unary, server-streaming, client-streaming and bi-directional call}. It
offers language independence support 11 programming languages.

What is Protocol Buffer
- Protocol buffer are language language-neutral, platform-neutral
extensible mechanism for serializing structured data
- Code generated for any language
- Very convenient for transporting a lot of data
- Data is binary and efficiently serialized (small payloads)
- Support Java, Go, Python, NodeJs, Objective-C, C++ and more with
proto3 language version.

REST vs gRPC
Features gRPC REST
Protocol HTTP/2 (Streaming) HTTP/1.1 or HTTP/2 [Request/Reply]
Payload/Serialization Protocol Buffer (binary, small) JSON (text, large)
Code Generation Supported through (.protoc) Third party tool like Swagger, Postman
Streaming Bidirectinal Client to Server. Request only
API contract Strict, Required Loose, optional, (Open API)
Security TLS/SSL TLS/SSL
Performance Fast Slow
Browser support Limited required [grpc-web and proxy layer] YES
