VMs also allow for even more isolation and data security, being more fully insulated systems of compute. For example, if your host machine runs Windows, you can run a Linux OS in a VM, and vice versa. VMs offer some advantages, as you can use a VM to simulate a different OS from the host system.

Unlike containers, VMs require a full replica of an OS to function. Like containers, virtual machines (VMs) are stand-alone computing environments that are abstracted from hardware. Containers also help isolate workloads, contributing to robust data security policies. IT departments can enable continuous integration/continuous delivery (CI/CD) with the agility and automation that containers provide.
Containers have only what you need, so they’re not bloated with superfluous software, and they won’t waste compute resources on background processes.īusinesses are discovering extreme value in using containers because they are portable, consistent, and user friendly. You can define and run multiple containers, each tuned to a specific workload for greater efficiency. A Linux container may only operate on a Linux host, a Windows container operates on a Windows host, and so on for other operating systems (OSs).Ĭontainers allow system managers to achieve more density with their architecture. The only restriction with containers is that they are reliant on their host system kernel. You can also use specialized containers for specific workloads, in the same way you might use a refrigerated shipping container to transport a specific type of cargo. You can pack a lot of cargo into a single container, and you can pack a lot of shipping containers into a single vessel or split them across multiple vessels. Containers have defined parameters and can run a program, a workload, or a specific task.Ī simple analogy to help understand containers is to think of shipping containers.

A container is an abstract unit of software that is a stand-alone, executable unit that has everything needed to run an application: code, runtime, system tools, and system libraries.
