Top 4 Reasons to Use Virtualization Docker

Docker is an open-sourced project that utilizes containers instead of virtual machines to manage server applications. This setup uses fewer resources for development and hosting, so it’s no surprise that Docker is taking the development world by storm. You can even use Docker with ASP.NET, and of course, you can leverage Stackify Retrace with your current stack, including Docker, for true app performance super-power.

 

Docker environment setup is essential when you're creating complex container deployments. As you might assume from the name, this file allows you to maintain environment variables for your containers. This comes in quite handy, as the docker env setup file can be reused for other containers or quickly edited--instead of editing the more complex docker-compose.yml files.

 

Using virtualization docker, your applications sit atop an excellent platform for packing, shipping, and running low-overhead, isolated execution environments. So it's no wonder that many companies are choosing Docker for deployment. But your deployment choices directly affect your development workflow because your Dev, Staging and Prod environments should match each other as nearly as possible.

 

No matter where you are on the stack, if your apps are deployed inside a container, you should get to know how to use containers in your development environment. The big news is that Docker makes it easy. Because Docker does not need an OS for each Docker container, the platform needs less memory and is faster to load. The advantages of Docker have made it one of the hottest new platforms. If you have not tried Docker yet, these benefits may change your mind.

 

1. Ease of Use

One of the best things about Docker is that it has a huge community to support it. The platform is based on open-source code, which means many people are invested in supporting Docker. This community support has generated an extensive resource of materials to help you get up and running.

 

2. Scales Well

Because Docker is so lightweight, projects use less space on servers. They can store more data and software in less space. You can even manage many resources---CPU, memory, network, etc.---each container can use. In addition, the containers can be resized to meet the needs of your application as it progresses. This allows an application to balance better than those on VMs, which are difficult to resize.

 

3. Resource-light

By allowing containers to share essential kernel functions, much of the unnecessary OS overhead is excluded. This can support up to four times more server application instances in the space a VM would need. Virtualization docker is also faster compared to a VM because it does not need to start an OS.

 

4. Offers Version Control

An essential feature of Docker is its built-in version control. Files in Docker are known as images. Each image file is composed of layers of images. A new layer is formed in an image every time a command is run. Therefore, changes to the code are automatically stored as layers in an image file. Image layers create a changelog into the image file. At any time, the image can be reverted to a previous image.

 

The ability to rapidly change between versions helps rapid testing. When testing, a change can be done and quickly reverted if desired by using a previous image. This is a prominent feature for developers that use an iterative design cycle.
