Container Management Software

Container Management Software Overview

What is Container Management Software?

Container-based virtualization (sometimes called operating system virtualization) is an alternative to hypervisor-based virtualization.

In the more traditional virtualization model, the hypervisor creates and runs multiple instances of an operating system so that multiple operating systems can be run on a single physical machine sharing the hardware resources.

The emergence of Docker, an open source container initiative has given a big boost to this category as a whole, as it has achieved broad industry buy-in for the container approach.

The container model eliminates hypervisors entirely. Instead of hypervisors, containers are essentially applications and all their dependencies packaged into virtual containers. Containers contain not just the application, but everything that it needs to run including runtime, system libraries, etc. All the containers share the resources of a single operating system and there is no virtualized hardware. Since the operating system (or kernel) is shared by all containers, they are necessarily much more lightweight than traditional virtual machines. It’s possible to host far more containers on a single host than fully-fledged virtual machines.

Another advantage is that containers sharing a single operating system kernel start-up in a few seconds, instead of the minutes required to start-up a virtual machine. Containers are also very easy to share.
