NestJS Application Deployment Overview

Deploying a NestJS application involves taking the code developed locally and making it accessible to users on a server. This process ensures that the application runs efficiently and securely and that it scales to meet user demands. In this lesson, we’ll explore deploying a NestJS app to Amazon ECS using Docker. Amazon ECS is a fully managed container orchestration service running Docker containers at scale.

What is Docker?

Docker is an open-source platform for developing, distributing, and executing applications within isolated environments called containers. These lightweight units package up applications and their dependencies, providing consistency and ease when transitioning between different systems. By virtualizing only the application runtime environment instead of entire VMs, Docker streamlines the deployment process by minimizing hardware requirements and addressing potential compatibility concerns.

To deploy a NestJS app, we’ll build a Docker image and run it in a container with the application and its dependencies. Once it’s in the container, we can be sure it will run smoothly on any computer or server with Docker ...
