The Importance of Docker in the Software Development

The implementation of Docker has changed the work of software developers as a team to create, update or transform web or desktop applications since there are many advantages when it is used. 

What are the advantages of using Docker?

Resource isolation

• It allows developers to encapsulate specific and necessary features for a project.

Increase productivity

• It helps software developers not to waste time configuring an environment, and the necessary dependencies of a system, since it allows them to deploy a project efficiently.

Standardization

• Docker can work with different containers that share the same system resources, allowing it to work with many applications.

Rapid deployment

• It makes it easier to create, deploy, and run applications.

Simplicity and efficiency

• Another functionality of the containers is that it allows to package of an application with all the features it needs, such as libraries and other dependencies, and send it as a single package. As a result, the developer will know that his/her/they application will be able to run on another device.

What are the Docker features?

Docker has many features that help us or facilitate the way to develop a web application or the way to implement an infrastructure to host our web applications. Those characteristics are:

• Docker has images. The image contains all the libraries and volumes that store the application.
• It shares resources with the operating system it runs on, so a container can be started or stopped in an easy way.
• Container portability drastically reduces the problems caused by different computer environments and saves us time by not forcing us to install other software to run the application.
• The container is light, and different containers can be handled in the same machine.
• Docker content is portable since containers can be easily moved.
• Docker images can be defined as operating systems with applications installed with the necessary libraries and volumes.
• Management of existing resources assigning them responsibly between deployed containers.
