3. Database: http://localhost:8000/db

Description

1. Redundancy achieved through 2 http workers echo_service_1 and echo_service_2. In case of failure echo_service_1 all traffic goes to the echo_service_2
2. Service Percentile 99 Monitoring is represented with Prometheus & Grafana stack: http://localhost:3000/d/000000003/echo-service-p99?orgId=1&refresh=10s (admin;admin)

Desired Improvements

1. Terraform:
   • Parametrize worker count
   • Templating worker containers
   • Templating nginx conf (upstreams)
2. Mariadb:
   • Store data in volumes

Uninstall

1. cd docker/terraform && terraform destroy -auto-approve && cd ../..
