Why do organizations choose to go to the time and trouble to adopt some form of virtualization technology? Those thinking that virtualization only refers to the use of virtual machine software to allow a single system to support multiple, encapsulated workloads would mention the factors of time and cost (see Cost and energy benefits driving virtualization).
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.

In my post, Single system image clusters: an idea whose time has come and gone?, I asked the rhetorical question "Are single system image clusters an idea whose time has come and gone?
I was speaking with Coby Gurr and Dan Cook of LANDesk yesterday about the LANDesk Application Virtualization technology. Thanks guys!
At one time, applications were constructed as a monolithic mass of code that implemented all of the functions required to implement a complete solution including user interface (if it faced users), application processing, data management and storage management. Some of the more sophisticated applications also included tools for application management and security.
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".
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.
