What is the benifit of web app for containers

What is azure Docker?

Now, let us understand what is Azure Docker?

Docker is a container management and imaging platform.
This supports operating systems like Windows and Linux.
Azure Docker is a container-based technology.
Docker is an open-source technology and runs on a single node.
Docker allows you to run containers. A container is nothing but a sandboxed process running an application and all its dependencies to host on an operating system.

What are Windows containers?

Windows containers are nothing but portable operating environments supported by the Microsoft Windows Server 2016 operating system.
You can manage windows containers by using different tools like Docker and PowerShell.
A container is a logical environment that is created on a computer where any of the applications can run.

There are two types of windows containers based on the Microsoft Windows server operating system

Windows Server containers: Windows server containers always rely on the windows server kernel.
Hyper-V containers: Hyper-V Containers are isolated virtual machines that incorporate their own copy of the Windows kernel.

Is Docker a VM?

Docker is a container-based technology and containers are logical environment which is created on a computer where any of the application can run.
On the other hand, Virtual machines are not based on container-based technology. Virtual machines are like servers: it is a computer within a computer that provides the user the same experience as a physical system.
So Docker is not exactly a virtual machine (VM).

What are Kubernetes containers?

Kubernetes is an open-source platform from Google for running containers.
This is a container orchestration system for Docker containers that is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.
You can use Kubernetes containers is mostly with Docker but can be used with other containers as well.

How do you stop a container?
