Infrastructure

Docker

Docker is used to package this application into a container, along with all of its dependencies, libraries, and configuration. This is helpful for ensuring the environment remains consistent between development and production, as well as between developers when collaborating on a project.

This project is also hosted on AWS, which automates the deployment of Docker containers via Elastic Container Registry (ECR) and Elastic Container Service (ECS). ECR stores container images, and ECS deploys and orchestrates these containers, enabling efficient scaling and load balancing for minimal downtime.

Terraform

Terraform is a tool for defining Infrastructure as Code (IaC), which allows me to commit the AWS infrastructure for this project alongside its code. Once defined, this Terraform configuration can be used to provision, update, and tear down actual AWS resources with a single command.

Managing my infrastructure definition and deployment through Terraform means that infrastructure is always implemented exactly as written, and allows me to iterate on infrastructure the same way I do with other code for this application.

AWS

The AWS architecture for this project is based on my fork of a project from testdriven.io. Their diagram of the AWS resources used is shown below:
