Virtualisation for embedded industrial systems

‘Virtualisation’ is a widely used term that encompasses a wide range of technologies and can mean very different things in different contexts. A virtualised cloud system will take on vastly different tasks than a virtualised enterprise system and does things that are even further removed from what a virtualised embedded system would do.

Although methods and end applications for different types of virtualisation differ, they do have one thing in common: taking a bounded set of physical hardware and making that set act like multiple virtual environments by creating partitions inside the hardware. Virtualisation can work at a server level, at a single platform level or at a network level.

It allows you to run multiple sessions for multiple people or tasks on the same server simultaneously (as cloud computing applications do), or to separate a single desktop into two virtual machines (such as when you use a laptop to run both Windows and Linux).

This separation of tasks and extension of resources can be valuable for many different end uses, but different virtualisation schemes will not all work equally within the constraints of embedded industrial systems, which include limited memory or limited power consumption caused by heat dissipation.
