PyConES2018 - Comparing gRPC+Protobuf vs JSON+HTTP in Python

gRPC+Protobuf or JSON+HTTP?

This repository contains 5 equal APIs: gRPC using Protobuf and JSON over HTTP. The goal is to run benchmarks for all approaches and compare them. The backend is powered by 5 microservices, 4 of which happen to be written in Python and the grpc-gateway proxy is written in Go.

Services organization

The application consists of the following application services:

Service	Port	Protocol	Description	Language service
django	8000	http	Provides a django webapp	Python
flask	8001	http	Provides a flask webapp	Python
grpc	50051	grpc	Provides a grpc webapp	Python
grpc-gateway	8002	http	Provides a grpc proxy	Golang
grpc-rest	8003	http	Provides a flask webapp which grpc client is called by request	Python

Requirements

• Install Docker
• Install Docker Compose

Run

docker-compose build
