Virtualization

Docker allows users to run applications isolated from a host computer, without the necessity of having separate operating systems for them to run on. Instead, you install and manage the Docker containers with a containerization engine (Docker daemon. As you start using Docker, you will face situations where you need to know how to share data between containers. 

Vagrant is a software package that creates a standardized operating environment. It does this using virtualization technology. Vagrant provides a command-line tool for loading and managing virtual operating systems. These can be customized using a text file and deployed across multiple systems. We will be using the VirtualBox provider in this tutorial. This guide will walk you through installing Vagrant on CentOS 7.

A virtualized server allows one piece of hardware to be used as multiple virtual servers. Learn about Server Virtualization, the types, & benefits.

With Docker Container Management you can manage complex tasks with few resources. Learn the best practices of Docker Containers.

Docker is an increasingly popular software package that creates a container for application development. Essentially, it creates a smooth operating system interface, so that applications running on it are compatible with most operating systems. Developing in Docker also helps speed up applications, since it shares the kernel and other resources (instead of pulling dedicated resources just for the application).
