General info

The main purpose of this thesis is to Compare the performance of microservice use gRPC and REST APIs for academic management system. So this project has 3 services:

1. KRS Service use golang.
2. Auth Service uses nodejs and also golang.
3. Payment Service use golang.

To store data in the database, I use Redis. Then use k6 to test the performance of each service and use Datadog to monitor the performance. All the services are deployed in different EC2 AWS as well as the test agent then use private IP to communicate.

System design

Technologies

• Golang 1.17.1
• Nodejs 4.17.6
• Redis 5.0.7
• EC2 AWS
• K6
• Datadog 0.36.0
• Linux ubuntu 20.4
  

Run service

1. KRS Service

$ URL_AUTH=172.31.24.28 URL_PAYMENT=172.31.28.177 KRS-service/main

2. Auth Service

Use nodejs

$  cd auth-service-nodejs && npm install && npm start

Use golang

$ auth-service-go/main

3. Payment Service use golang.

$ payment-service/main

Run test

1. Run datadog agent

DOCKER_CONTENT_TRUST=1 \
sudo docker run -d \
    --name datadog \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    -v /proc/:/host/proc/:ro \
    -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \
    -e DD_SITE="datadoghq.com" \
    -e DD_API_KEY=<YOUR_DATADOG_API_KEY> \
    -e DD_DOGSTATSD_NON_LOCAL_TRAFFIC=1 \
    -p 8125:8125/udp \
    datadog/agent:latest

Don't forget to replace <YOUR_DATADOG_API_KEY> with your datadog api key

2. Run the test

All test files are in test directory. For example, if you want to test grpc-krs-create in 100 vurtual user in 30 second use the command below.

 K6_STATSD_ENABLE_TAGS=true k6 run --vus 100 --durations 30s --out statsd --tag test_run_id=1 -e IP=172.31.30.48 test/grpc/krs/create.js

Result

Grpc

Rest

Datadog
