   <p class="inline">In addition containers are portable, meaning that they will run whatever program they contain in the exact same way every time it is launched, and wherever it is launched.  In other words applications will run consistently in a standardized environment, even if the container is launched from the cloud or from a physical server. This practically eliminates the need to do lengthy custom installations on every single machine in a network, an application can simply be run from a container. Portability will also help with running legacy applications, in the sense that if an older app needs a specific environment for it to run (for example, older versions of Java or Python), that environment can be recreated in a container.</p>

   <p class="expand mw-collapsible-content">However, there are some limitations still present, containers from one platform (like Docker) can’t be run on another platform (like Linux Containers) and there are also backwards compatibility issues, containers designed for the newest version of a platform may not work on older versions. <ref>Tozzi, Chris.
