There is the CoffeeShop web app with backend and frontend developed using Node.js:

• Backend is the RESTful API, which works with a PostgreSQL database and has background jobs.
  • Backend ReadMe
• Frontend is the React app.
  • Frontend ReadMe

App will work under a load with peaks in the morning and in the evening about ~1000 RPS.

That’s what you need to do:

• Try to make the app stable, secure and reliable
• We need to place this app in k8s, use in-house DB and should have 2 env (staging and production)
• Envs are almost the same (the storage volume and the load are different though)
• Staging server load is five times less than production one.
• PostgreSQL requirements:
  • staging: 256 Mb,
  • production: 512 Mb.
• Develop IaC:
  • Develop necessary things to deploy and run the apps in k8s.
  • It would be great if you could use Terraform/Terragrunt, Helm and we could deploy it to Minikube.
