August 31, 2010 -- Virtualization already has impacted the server and IT industries in a significant way. IT organizations are using it to reduce power consumption and building space, provide high availability for critical applications and streamline application deployment and migration. The trends to adopt in the server space also are being driven by the desire to support multiple OSes and consolidation of services on a single server by defining multiple virtual machines (VM). Each VM operates as a standalone device. Since multiple VMs can run on a single server provided the server has enough processing capacity, IT gains the advantage of reduced server inventory and better server utilization.

Although not mainstream, similar trends are trickling down into the embedded space as well. The concept of having a sea of processors and the associated processing capacity sliced and diced between applications and processes is not science fiction anymore. The challenge of extracting higher utilization on the processors and consolidation triggered by cost reduction are driving the adoption of virtualization in the embedded systems.
