Benefits

● High-performance communication

● Less bandwidth usage

● Multi-language/platform supports

● HTTP/2 and SSL/TLS usage

● Supports Bi-directional Streaming operations

Drawbacks

● Need additional library to generate codes

that increases complexity

● Can't read incoming-outgoing payloads that

is not good for client to service

communications
