What is Docker?

A tool that packages your application and everything it needs to run into a standardised container

Why It Matters

Docker ensures your app runs the same everywhere, eliminating 'it works on my machine' problems

A Docker container includes your app, Node.js, and all libraries, running identically on any server

A lightweight, isolated package containing an application and everything it needs to run

A system for automatically managing, scaling, and deploying containerised applications

The process of making your application available for users to access on the internet

The process of making your application available for users to access on the internet

A system for automatically managing, scaling, and deploying containerised applications

A lightweight, isolated package containing an application and everything it needs to run

A computer that runs continuously to handle requests, store data, and serve your application to users

A way to run code without managing your own servers, where the cloud provider handles everything

Code that runs on servers close to your users around the world, rather than in one central location
