Even though there are several different technologies involved and several different types of requirements, it now appears that any mulit-machine configuration is called a cluster. Here's a quick summary of the different configurations that are now using the same IT jargon term "Cluster".
Virtualization reaches from hand-held devices to the data center to the clouds. Virtually Speaking examines the forces behind this expansion, the suppliers of the technology and the organizations using the technology.
Daniel Kusnetzky, a reformed software engineer and product manager, founded Kusnetzky Group LLC in 2006. He's literally written the book on virtualization and often comments on cloud computing, mobility and systems software.

EMC Corporation has announced that it intends to sell 10% of VMware in an initial public offering. The announcement itself can be seen here.
Since my conversation with the good folks at Red Hat (see Discussion with Red Hat’s Joel Berman and Nick Carr - 1st take) I've been thinking about the company's strategy and how that plays out in the real world. Red Hat presents the notion that a stack of open source software can address organizations' IT requirements nearly as well or as well as can proprietary software.
Virtualization technology is just that, a technology. An organization's requirements and budget must be considered before a specific technology is selected.
An announcement from SWsoft just came to my attention. The company is offering a very simple way for small or medium sized organizations to deploy operating system partitioning or virtualization.
Even though Xen, virtual machine software for industry standard systems, is well known, The company behind this software, XenSource, is not as well known. XenSource, with the help of the open source community, has developed software that securely juggle multiple virtual machines, each running its own operating environment, on a single physical system and produce close-to-native-machine performance.
I was offered the opportunity to speak with Kelly Vizzini, CMO of DataSynapse, the other day. She introduced me to a new member of her staff, Shayne Higdon, VP of Product Marketing.
As I mentioned in my post, Overview of Novell's views on virtualization and again in my post, Conversations with Cassatt and Marathon, Thoughts on Novell and Red Hat, Novell appears to be focusing a great deal of attention on managing virtualized environments not just the tools of virtualization themselves. Along those lines, I had an opportunity to view a demo of Novell ZENworks Orchestrator presented by Richard Whitehead and Alan Murray of Novell the other day.
I've been following Cassatt for a number of years and have always thought that the company has taken a fresh, different view of the concept of virtualization in the implementation of its product "Collage". In an attempt to catch up with what the company is doing now, I spoke with Jay Fry and Ken Oestreich.
A few days ago I had the opportunity to speak with Marathon Technology's, Michael Bilancieri, Director of Products, and Steve Keilen, Vice President of Marketing about creating both highly available (HA) and fully fault tolerant (FT) environments using industry standard systems. It was a very interesting conversation.
