Virtualization
You have eagerly implemented virtualisation to reap its many benefits – but if disaster strikes, will you find your disaster recovery techniques and hardware configuration have not kept pace with your changed production environment?
Virtualization was supposed to solve server sprawl and offer a simple route to data center consolidation. It hasn't. Virtual machines are so easy to deploy that many organizations are now suffering VM sprawl. They have reached the point where they do not know how many VMs they have and have no way to manage them. Rampant virtualization can turn out to be a curse, not a blessing. How can it be controlled?
From the vendor, press and analyst community, it looks like it is all a done deal - virtualisation has swept the board, everything is now fine in the garden, and it's now time to move on to the next big thing, being cloud computing. Pity, then, that estimates are that fewer than 10% of servers out in the world are actually virtualised - and that even that those that have been virtualised are still mainly in test and development environments.
Most Recent Virtualization
Enterprises that seek a successful move to virtualization have a number of hurdles to overcome. Not all are obvious. Virtualization offers a lot of benefits to the organization that implements it correctly. This paper identifies seven key things that you must know if your business is to be successful in virtualizing your mission-critical applications.
Adding Unified Communications to the Virtual Data Center
This paper explains how the worlds of data and voice have evolved separately in recent years, and what has kept them apart for so long. But it goes on to describe how a leader in the world of data center technology, and another in the world of telephony, got together to do something that many thought impossible – to join the worlds of data and voice on a single virtualized infrastructure.

There always seems to be a "fly in the ointment" of every great idea. This is no less true in the area of server virtualization. While hardware costs have been dramatically reduced in data centers where servers reside and electricity consumption has dropped, the lack of effective disaster recovery plans and implementations for the virtual environment looms large.
More and more Australian businesses are finding that there are distinct benefits associated with designing ways in which whole companies can be made to sing from the same hymn sheet when it comes to business procedures, tools (e.g. software programs) and techniques. One of the ways in which this can be achieved from the IT perspective at least is virtualisation.
At the Open CeBIT conference in 2008 Longhaus stated that by 2012 the open source business model would be a fully integrated dimension of the overall software market. Part of the logic behind this forecast was that the presence of a new business model in an existing market that offers the same outcomes at a reduced cost will cause a reaction from other market participants.
