Basing software appliances on a virtualization technique known as "Containers" enables the deployment of the software appliance on any host running a relevant containerized operating system. Basing virtual appliances on containers avoids incurring the additional overhead normally associated with virtual machines. For example, basing virtual appliances on containers avoids the installation, configuration and maintenance costs associated with running complex stacks of software, as well as the need for on-site support, while simultaneously avoiding the performance overhead and scaling limitations associated with running virtual machines.
