mathserver

This repo contains various implementations of a basic server built in go that can execute the following operations:

• Divide
• Max
• Min
• Multiply
• Pow
• Subtract
• Sum

Purpose

The purpose of the various implementations provided in this repository is to give an example of how/when different implementation styles should be followed. The implementations compared are go-kit, standard gRPC, and standard HTTP. The goal is to simply compare coding style and readability. Performance and efficiency of execution will not be compared.

Comparison

The implementations are as follows:

Client Implementations:

• Supports both gRPC and HTTP
  • gokit:
    • Total number of lines written: 103
    • gRPC is achieved via go-kit gRPC client
    • HTTP is achieved via go-kit HTTP client
  • grpc_and_http:
    • Total number of lines written: 223
    • gRPC is achieved via standard gRPC library
    • HTTP is achieved via standard net/http library
• Supports gRPC only
  • grpcnative:
    • Total number of lines written: 96
    • gRPC is achieved via standard gRPC library
