How Doker Works

[sumaiyakhatun26]

According to Wikipedia, Doker is software that automates the processes of deploying and managing applications in a special virtualization environment. The work is carried out at the operating system level . With the help of this software package, applications are packaged into containers along with their environment and dependencies, and the user is provided with an environment for managing these containers.

This definition can be formulated more simply. Docker is a special tool that allows specialists to run their applications in containers - a kind of sandboxes for the target operating system.

The main advantage of this approach is the ability to package any application russia rcs data being developed with all its dependencies into a standard development module. Docker differs from a virtual machine in that containers do not overload the system, which allows for more efficient use of resources.

However, the use of virtual machines is considered the standard in software development and launch. Applications are launched inside a guest operating system, which uses the resources of the host OS to virtualize the hardware.

This ensures complete isolation of the applications from the main operating system and, as a result, increases security. However, this places an additional computational load on the real hardware.
