1. Introduction

gRPC is a high performance, open source RPC framework initially developed by Google. It helps in eliminating boilerplate code and helps in connecting polyglot services in and across data centers.
You can define how you want the information you’re serializing to be structured by defining protocol buffer message types in .proto files. Each protocol buffer message is a small logical record of information, containing a series of name-value pairs.

2. Download project using git

Use the following command to clone this repository:
