OSNews, Generic OSes I was lucky enough to receive an invitation to the HP Technology Forum 2010 via OSNews and just spent most of this last week in Las Vegas with five thousand other nerds of varying caliber. The tech forum is focused more on enterprise technology than that of the consumer, and-- let's face it-- even if any of us could afford a $30,000 rack of servers, most of us have little idea of what we'd do with so many resources except brag. Despite the focus on an area not quite as natural to OSNews and many of its readers, there was a plenitude of good and interesting information shared-- aside from that, the forum was simply fun. There were a few subjects that were especially eye-catching, though many of them not necessarily comprehensive enough to base an entire article on; thus this overview.

Virtualization

First Disclaimer I work for HP and regularly implement most of these technologies for customers, Virtualization, Virtual Connect etc....

I describe Virtualization and VMWare as good enough computing. Which is really just an extension of existing IT dept practices of buying a single service for every service. However the reality is while the hardware has grown exponentially more powerful the user demand has not. Most IT shops have a 5 year recap cycle but the customer demands haven't increased with the new server capabilities. Hence you had servers that where 20% utilized now 1 to 2 % utilized. So virtulization allows us to consolidate those workloads while maintaining the logical separation that IT has adopted. Luckily open systems virtualization has great features to really provide some benefits over a single box, live migration allows me to move a VM with no downtime between physical servers is a key one. Now with virtualization I can proactively fix hardware problems without bringing down services and without clustering complexities. Virtualization allows me to reserve specifically CPU and Memory resources in a pool to gurantee VM performance. Not to mention some customers love the single hardware platform for development to deployment.... It does simplify many things.

However Virtualization everything is not a good motto. Some things don't scale\work\make sense to be virtualized and in those cases Bare Metal make most sense.

Virtulization will always have a place unless there is a radical change in the way mainstream OSes operate. Someday maybe but my guess it will always be easier to virtualize.

In fact I would argue we will see OS's change to virtualize better. Thinner OS'es with less complexity, just enough to host the application.
