Understanding Virtual Machines and Containers
What is a Virtual Machine
• A virtual machine is a computer file, typically called an image, which behaves like an actual computer – computer within a computer
• It runs in a window, much like any other program, giving the end-user the same experience on a virtual machine as they would have on the host operating system itself.


What is a Container?
• A containerization is an approach to software development in which an application or service, its dependencies, and its configuration are packaged together as a container image. You then can test the containerized application as a unit and deploy it as a container image instance to the host operating system.

Containers vs VMs
Containers are lightweight because they don’t need the extra load of a hypervisor, but run directly within the host machine’s kernel. This means you can run more containers on a given hardware combination than if you were using virtual machines. You can even run Docker containers within host machines that are actually virtual machines!

What is Docker and its Benefits
• Docker is an open-source platform for developing, shipping, and running applications by using containers.
• Docker enables you to separate your applications from your infrastructure so you can deliver software quickly.
.
Benefits of Docker:
1. Resource Efficiency: Docker is lightweight and fast. Process level isolation and usage of the container host’s kernel is more efficient when compared to virtualizing an entire hardware server using VM.

Docker is available for implementation across a wide range of platforms:
• Desktop: Mac OS, Windows 10.
• Server: Various Linux distributions and Windows Server 2019.
.Alternatives to Docker
1. Open Container Initiative (OCI)
2. CoreOS and rkt
3. Apache Mesos and Mesosphere
4. Canonical and LXD

Docker Architecture and its Taxonomy
Docker Engine is a client-server application with these major components:
• A server which is a type of long-running program called a daemon process.
• A REST API that specifies interfaces that programs can use to talk to the daemon and instruct it what to do.
• A command-line interface (CLI) client (the docker command).

Docker Daemon
• The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes.
• A daemon can also communicate with other daemons to manage Docker services.

Docker client
• The Docker client (docker) is the primary way that many Docker users interact with Docker.
• When you use commands such as docker run, the client sends these commands to Docker Daemon, which carries them out.
Docker Image
• A package with all of the dependencies and information needed to create a container. An image includes all of the dependencies (such as frameworks) plus deployment and configuration to be used by a container runtime.

Container
• An instance of an image is called a container. It's a process by itself and each process has its shown hostname like a Virtual Machine.

Repository (also known as repo)
• A collection of related Docker images labeled with a tag that indicates the image version.
