The Docker containers sit on top of the operating system of the underlying host machine.

You can separate your applications from the underlying host infrastructure and can deliver software applications quickly by reducing the delay in building the code and deploying production. This will allow you to develop and share applications easily. You can create packaged, isolated, and platform-independent containers with all the libraries and dependencies pre-built. You can check out this complete step-by-step guide on Docker.ĭocker is a free-to-use, open-source container-management platform that provides tons of tools and utilities to build, test, and deploy applications. So with no further ado, let’s get started. You will look at the Docker architecture and understand why it is better to use Docker containers. In this tutorial, you will explore everything about containers and the most popular container-management platform called Docker. You can check out the complete guide on Docker Vs. Because of lots of such downsides, developers decided to adopt a newer and simpler technology called containers. They also took quite a lot of time to boot up. Since each guest OS has its system and configuration files, the size of a VM instance is quite large, usually in the range of gigabytes. Each guest operating system (VM instance) running on the underlying host machine has its operating system and kernel. However, Virtual Machines virtualize the hardware of the underlying operating system and sit on top of a software called a hypervisor. These include beta testing of an operating system, working with virus-infected files, etc. Virtual Machines provide a secure and isolated environment and are quite useful when you want to execute those tasks that are sensitive to security breaches, that might carry the risk of infecting the host.
In the good old days, organizations used to rely on Virtual Machines to implement their microservices architecture. Docker is one of the most popular container-management platforms.
