In contrast, a VM requires a full OS image that adds to the size and performance of the VM. Generally, they have a minimized subset of guest OS required by the application. Benefits of Using Docker Containersĭocker containers come with several benefits that streamline application development and deployment.Ĭontainers usually don’t contain primary OS images. Containerized applications come with all the benefits of virtual machines without the performance overheads of higher resource consumption. You can install docker on Ubuntu, Linux, CentOS, and many more open-source operating systems. While developers can bundle everything from the OS kernel and all required libraries in a single deployment package, Docker greatly simplifies and speeds up the process. Containerized applications are especially popular in cloud and hybrid environments where developers and sysadmins need a way to work around code dependencies and OS-level services. As a result, the application can be deployed and executed without worrying about dependencies and similar issues.

The term Docker refers to a very popular set of Platform-as-a-Service products that create and manage containers (isolated virtual environments for building, deploying, and managing applications).ĭevelopers prefer containers because they combine all resources in a single environment, including the OS and required libraries.
