Main

Architecture

This project uses:

• Nextjs as its frontend;

• Golang & Expressjs as the backend servers configured with Nginx for load-balancing;

• MongoDB as non-relational db for authentication

• Redis as in-memory key-value db for url keys management

• For scalability and portability, both the frontend and backend are containerized using Docker and can be spun-up easily using docker-compose and can be orchestrated using the Kubernetes (the manifest files have been provided).

• Terraform is used for Infrastructure creation and Ansible playbooks and roles are used for configuring EC2 instances created on AWS providing:

  • Installation of Docker on those instances
  • Running of the url-shortener service through user input
