A container contains all the necessary software components like binary codes, configuration files, libraries, etc. It is like the operating system virtualization of a small or large application. But they do not contain OS images. This makes them easy to manage, lightweight and portable.

But when you are using the container for a larger application or deployment, you need to use many containers. When the number increases, you need to use Docker to orchestrate and manage those containers. Without proper management, the huge number of containers will struggle, resulting in slow app deployment and running processes.

In this article, we will talk about the Docker use cases and the benefits of using Docker. So, without any further delay, let’s get the ball rolling!

What exactly is Docker?

Docker is a containerization platform. The containerization process involves packaging up the software and all its dependencies like a container. This technology runs that software smoothly and uniformly across any infrastructure.

So, the primary purpose of Docker is to make a simple, easy and safe platform to manage and deploy containers or apps. You can also call Docker PaaS (Platform as a Service). Docker engine can host and deliver software containers using OS-level virtualization. But it is not a virtualization machine. But developers are using Docker over VMs.

Why use Containerization Technology?

We all know Docker is a great platform for containerization technology. But you might be thinking, “Why don’t we use other technologies?” If containerization technology is the best, then people will feel Docker’s fundamental necessity. First, we need to understand the reason for using containerization technology to understand the necessity of Docker.

As we all know, containers are small pieces of operating system virtualization. They share the resources of a single instance of the host operating system. This prevents the extra usage of memory and CPU. It also provides other benefits, like

  • Portable: The standardized format of containers makes them portable between hosts and registries. Any container host can pull or push images.
  • Greater Efficiency: Container orchestration brings great value to the use of resources. Also, it can run many copies of an app again and again on the same hardware…
