To successfully run an application on a virtual machine, the hypervisor needs to first import the virtual machine and then power it up, and this takes time. They require more computing resources to execute.

They are heavyweight, usually resource-hungry and not so easy to set up-virtual machines require full installation. There are many drawbacks-they contain all the features that an operating system needs to have: device drivers, core system libraries, and so on. Virtual machines are fully isolated, hence very secure. There can be a lot of use cases that would make an advantage from using virtualization-the biggest asset is that you can run many virtual machines with totally different operating systems on a single host. Type 2 hypervisors, on the other hand, are commonly used as a desktop virtualization-you run the virtualization engine on top of your own operating system. Type 1 hypervisors provide server virtualization on bare metal hardware-there is no traditional, end user’s operating system. There are two types of virtualization hypervisors: Type 1 and Type 2. Traditional virtualizationĪ traditional virtual machine, which represents the hardware-level virtualization, is basically a complete operating system running on top of the host operating system. Let’s compare those two technologies now. To fully understand what Docker really is, first we need to understand the difference between traditional virtualization and containerization. You can think that maybe Docker is a virtualization engine, but it’s far from it as we will explain in a while.

It allows programmers and DevOps to build, ship, and run their code anywhere. It’s not a programming language or a framework, rather think of it as about a tool that helps solving the common problems such as installing, distributing, and managing the software. Once you’re done with it, you can just destroy the Docker image and it’s as though nothing ever happened.

With Docker, you can build some Node.js or Java project (but you are of course not limited to those two) without having to install Node.js or Java on your host machine. This guarantees that it will always run in the same way, no matter what environment it will be deployed in.

Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, and system libraries-anything you can install on a server. The basic idea behind Docker is to pack an application with all of its dependencies (let it be binaries, libraries, configuration files, scripts, jars, and so on) into a single, standardized unit for software development and deployment. We will begin with a basic idea behind this wonderful tool.

A difference between virtualization and containerization.

In this article, we will cover the following topics:

(For more resources related to this topic, see here.) But what about preparing our software for shipment and the deployment? Let’s see how Docker fits into that scenario and can help us being agile. We use methodologies such as Scrum, estimate our work in story points and attend the daily stand-ups. Software development today needs to be agile and react quickly to the changes. team, which is the main sponsor, there are some other big names contributing to the tool –Red Hat, IBM, Microsoft, Google, and Cisco Systems, just to name a few. Later on, in March 2013, it was released as open source. In this article by Jaroslaw Krochmalski, author of Developing with Docker, at the beginning, Docker was created as an internal tool by a Platform as a Service company, called dotCloud.
