What are dockers and what are the benefits?

 Overview

The popularity of Docker has constantly increased over the past few years. It is completely changing the way in which the software’s is produced and developed. The container of docker allows the immense economy to scale up and have made development more scalable. Moreover, at the same time keeping the process user-friendly it allows you to gain more attention from the users.

The docker command returns a live data stream for running the containers. Moreover, to limit the data to one to one or more specific containers, you need to specify the list of container names or separate them by using the spaces. Docker has been a game changer since its release of 2013. It is becoming massively popular due to the containerization technology. 



Docker is a very popular and well-known container that supports multi-purpose businesses. Let’s now have a look at the definition of docker.

Defining dockers.

Docker is an operating system-based virtualization software platform that allows the IT organizations to easily deploy, create, and run applications in the docker container.

The container itself is really just a very lightweight package that has all the instructions and dependencies like the libraries, frameworks, bins within it. In the DevOps life cycle. You can use the docker platform at the multiple stages of a DevOps development cycle.

Now you know about the definition of docker, you must now know about the difference between the virtual machine and docker. Let’s have a look at the difference between docker and virtual machines.

Dockers Vs Virtual Machines.

There are some of the differences between Docker and Virtual Machine. Some of the things are good about the dockers and some are good about the virtual machines. Like the memory usage is good in virtual machines and portability is good in the dockers. Here is a table depicting the comparison between dockers and virtual machines.

Dockers Virtual Machine

It has the Docker engine layer. It has the hypervisor layer.
Environment, memory usage is very low.     

With virtual machines the memory usage is very high. Create a Virtual Machine for windows 10 and see for yourself.
 
The performance is always high because of the single docker engine. The performance is poor while building out a virtual machine.

Docker is designed for portability. It is not ideal in terms of portability.

Here the boot-up is instantaneous. The boot up timing is slow.

These are few of the comparisons between docker and virtual machines. You can use these comparisons to choose the best platform to grow. Let’s have a look at the benefits of docker.

Benefits of Dockers.

There are multiple benefits that can attract you to use the docker services. These benefits make you fall in love with the docker services. Here are some of the benefits of docker that makes it special.

•    Portability: It is one of the most important factors that affects the benefits and working of dockers platform. After testing the containerized application’s you can deploy it on the other systems where the docker is running and you can make sure that the application will perform exactly as it did when you tested it in the development process.

•    Performance: However, the virtual machines are alternative to the containers, but the fact the containers do not have an operating system means that the containers have much smaller footprints than the virtual machines, quicker to start and faster to create. With the improved performance you can easily increase the performance of your website.

•    Agility: With the portability and performance benefits it offers the containers the ability to help them make the development process more responsive and agile. It enhances your continuous integration and delivery process to take the advantage of the technology and containers such as the enterprise developer build tools for the windows to make it easier. To deliver the right software at the right time you need to have the right tools.

•    Isolation: The docker containers have one of the applications that also includes the relevant versions of any supporting software that your application requires. Moreover, the other docker containers contain the apps that require different versions of the supporting software.

It is not a problem because the different docker containers are totally independent of one other. It also means that as you move through the stages of your development lifecycle, you can have the total confidence that an image you create during the development.

•    Scalability:  You can quickly improve the scalability and push the limits of your business using the docker containers. You can create a new container on demand for your application requirements. Moreover, when you use multiple containers you can take the advantage of a range of container management options.

These are some of the benefits of docker containers that you can keep in mind while using the services. Let’s have a look at the final thoughts.

Bottom line

There are various applications of docker that you can use to enjoy the benefits of docker containers. You can look at the benefits of the dockers to have better services and get the perfect output of your investment.
