What is Containerization & Why? The Problem When you develop a application, It may work fine on your PC or Laptop. But when you going to deploy it, Sometimes It will not work properly in production or others computer. Reasons Version Problems Missing Dependencies Other programs may disturb yours. Because everything is on same server/PC. Solution To solve this issue, Developers uses a technology called Containerization. Containerization Containerization is a lightweight alternative to full machine virtualization that involves encapsulating an application in a container with its own operating environment. This provides many of the benefits of loading an application onto a virtual machine, as the application can be run on any suitable physical machine without any worries about dependencies. It means, Each and every application / services can work on dedicated environment is same machine (Like Virtual Machine But Not Exactly). Just Image a Container & Ship. The stocks are packed into containers. And each containers are locked and shipped. The actions inside container will not effect the ship. Because container is protecting/separating outside. Just Like that, Imagine you computer as a ship. Now you can create a separate container for Database, separate container for App, separate container for Cache and so on. And you can deploy all together in your ship (Computer). So each services can run independently, If any service occurs, It will not effect your server. What is Docker? Docker one of the most famous containerization tool, use by Software Engineers. It allows you create, maintain & deploy containers easily. Virtualization vs Containerization
