X86 Virtualization is a key enabler for business; virtualization allows you to get more computing done with less hardware. Realizing the full advantages of these technologies can however be very costly. The most beneficial and sought-after features are also often the most expensive. Every market experiences commoditization over time, and x86 is no exception. Once a costly technology unavailable to any excepting the largest enterprises, the bare essentials are today available as free type 1 hypervisors. Fast, simple, and compact, these free hypervisors can virtualize multiple operating systems on a single piece of hardware, but not much else.

If you are interested in virtualization for any reason other than condensing...

Virtualization is a hot topic in business IT these days and it can be difficult to keep track of all the latest trends and stories. To help you stay on the front foot, here’s our summary of some of the latest research, news and important issues being discussed in the world of virtualization in July 2011.

Upping the Ante

Virtualization is going from strength to strength - and it’s getting serious. On July 12th both Microsoft and VMWare announced their latest products for full server virtualization. These releases, Windows Server 8 and vSphere 5, seem to be focused on addressing many of the widespread concerns which are preventing many people from deploying virtualization as a business IT...

Virtual Application Manager (VAM) allows easy management of virtualized applications. It is an administrative tool, using a clear, intuitive interface to simplify control of layers over a network. For more information on application virtualization, see the ‘Software Virtualization’ section of our welcome post. The remote machines must be running either SVS (Software Virtualization Solution) or the upgraded version, SWV (Symantec Workspace Virtualization). If you are not familiar with this product, it is a piece of software allowing the user to virtualize applications. This software is not required on the host. The VAM interface gives administrators the power to connect to a remote machine and view all of the virtualization applications which are installed on it, as well...

If you run a business, your IT infrastructure is probably a major concern when it comes to the efficient functioning of all sorts of day to day tasks, ranging from the menial to the absolutely essential. A lot relies on getting the right system and right team to work with it. To a lot of businesses, the cloud seems too good to be true. Vendors harp on about all the benefits; cheaper costs, portability, simplified scalability, etc. When it comes to the people who actually have to pay for these changes, in the hope that these benefits will materialise, they are rightly skeptical. After all, a cloud solution could well be cheaper to start with, but if it goes wrong then it means a lot of disruption and wasted resources to switch back to the old ways of working.

According to the results of one of our latest surveys - the...

While virtual servers remove many constraints caused by tying operating systems and applications to hardware, they are still subject to the same risks and issues associated with their physical equivalents. A server is a server, with processing, memory and I/O, after all. But just because it shares the same facets as a tin-and-silicon machine, does this mean it should be secured in the same way? To answer this, it’s worth thinking about the architecture that results from server virtualization. You will still have physical servers (it’s a bit hard to do without them) each of which will be running several virtual servers. As such and from a security perspective, you’ve actually added a layer – which can be both a benefit and a constraint.

Advantages & Disadvantages

First, the advantages. In principle, a virtualized environment can benefit from all the security measures already in place in the physical world. If physical servers are in a...

VirtualStorm VDI allows a client computer to access a virtualized operating system from a central server. This means that most of the applications running on the client computer are usually being accessed from elsewhere on the server (although some a run natively). A problem with this way of running a network is controlling how and when client computers are able to activate these external applications - solutions are usually complicated or give too much authority to the users, allowing people to steal programmes, as virtualized applications are highly portable. DVS S.M.A.R.T provides a solution to this by allowing users to remotely access and activate applications without ever having a real copy on the client computer.

Welcome to IT Industry Trends, the new virtualization blog from Symantec. We’ve launched this blog to give us a place to talk about all aspects of virtualization, cloud computing and more, with information for those of all levels of knowledge and expertise. Before we get started, though, it never hurts to take a look back at how virtualization started, what it is and why people are realising that it’s now a key part of any enterprise IT strategy.

What is Virtualization?

Very basically, virtualization is the creation of one or more emulated computers on one single physical computer. It is referred to as emulated because it is not running directly off of the computer’s hardware, but on a virtual recreation of this hardware - in other words, software pretending to be hardware. This means that one computer can split up its real physical resources (RAM, processing power, etc.), and simulate multiple computers instead. Each of these has...

Technologies such as virtualization and cloud computing offer the potential to reduce costs and improve operational efficiency – benefits organizations can’t afford to ignore. The shift to a cloud-based IT infrastructure is a goal for many, with 75 percent of enterprises at least discussing the implementation of these technologies. Whether you are just beginning to implement virtualization and private cloud computing or are already in the process, here are a few recommendations to give you the smoothest transition possible, based on the results of our 2011 Virtualization and Evolution to the Cloud Survey.
 
Keep expectations realistic. Because virtualization and cloud computing are still maturing, it can be a challenge to set...
