Docker Container : Why is it so popular?

So, you heard too much about docker, right? What is Docker? Why is it so famous? We are gonna answer that in this Blog.

When you deploy software from your local machine to the server you may face many hassles to set up the exact environment to run the software in production. The hardship can be because of server settings, differences in the operating system, and setup environment. To handle these issues 6 years back Docker was introduced and is in active development since then. All the Big Companies like Paypal, VISA, etc are adopting this lightweight container-based virtualization. To date, 4 million
applications have been placed in containers using Docker technology. Docker is popular as it is integrated into almost all cloud-based platforms from amazon to Alibaba.

Type: SAAS (Software as a Service)

Container V/s VM

The main difference between the docker container and virtual machines is that VM abstracts all the resources of a device but Docker only abstracts the operating system Kernel.

Docker is a program that performs operating-system-level virtualization. Docker engine runs on the top of the operating system and manages all the dependencies so the application runs quickly and reliably from one computing environment to another. Basically, docker is a container-based packaging system. The docker application creates a Docker image. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings. Docker Image Becomes a container when they run on Docker Engine. Docker engine is run on top of Host Operating system and is connected using a Docker Program in different Infrastructures.

Docker reduces the Time frame to manage your server as you only have to define the dependencies and environment once then you are all set in whichever environment you choose to deploy your server. Docker containers are cost-efficient, secure, and reliable. Docker Containers Are Everywhere: Linux, Windows, Datacenter, Cloud, Serverless, etc. that is why it is so popular.

Note: For Docker to run, Vtx (Virtualization Environment) is needed so, As Windows 10 Home edition does not support Hyper-V see here: https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/quick_start/walkthrough_compatibility.
The Workaround is to use the VirtualBox version of the Docker Application.
