Virtualisation brings enormous benefits to organisations everywhere, fundamentally altering the way in which they do business. It’s not a new concept, of course, but we are now seeing it being applied across areas that go way beyond simply machines and hosts.

Let’s look first at the virtualised world itself and its adoption among organisations: Enterprises are now operating at around 50-55% virtualisation in their data centres, with the goal of taking that to 90% or even higher. It’s a huge opportunity and a massive challenge, especially when it comes to security; because security has always struggled to keep up in the virtualised environment.

Generally speaking, there is a ‘tax’ to be paid when you put security into such an environment and usually that tax relates to performance – everything tends to run much slower. The upshot is that you no longer have the capacity you want and need – which runs counter to the whole point of having virtualisation in the first place...

Few areas of IT seem to be gaining as much attention at the moment as cloud orchestration, as represented by OpenStack and CloudStack, VMWare and the like. The debates in the blogosphere and on social media could suggest nothing short of all-out war as different vendors and groups back one approach or another. 

To understand what's going on, it is best to start with the elephant in the room - Amazon, whose Elastic Compute Cloud(EC2) service (now part of its AWS portfolio) scared the socks off other vendors when it came to market - not least because it offered a fundamentally different approach to computing, compared to traditional, in-house systems. 

The Amazon model is based on the enormous power of virtualisation, which enables processing workloads to be allocated to computer hardware far more dynamically than was possible in the past. This is what gives EC2 its '...

Ask anyone who has worked in IT for any length of time, and they will tell you the devil is in the detail. While a product might look great on paper or as part of a well-rehearsed demo, post-deployment the grass may not be so green. Frequently, the biggest issues with implementations or upgrades are caused by integration with technologies already in place. The more embedded a product is in the infrastructure, the more likely it is to hit challenges.

As Symantec is, essentially, a purveyor of infrastructure products and services, we are acutely aware of such issues – indeed, it is our business to help organisations of all sizes reduce the risks that they cause. And given that no technology has had a bigger issue on IT infrastructure over the past decade than virtualisation, we have made it our business to help organisations address that, too.

At VMworld this summer, we announced no fewer than...

"Sometimes I like to think of Symantec as an elephant," said Angela Tucci, Symantec’s chief strategy officer, over lunch at London’s Soho Hotel. "Depending on which side of the elephant you look at," she explained, "you get a completely different perspective of the creature."

Strip away all the technical jargon and a virtual machine management package is just a software program, which emulates a real computer for each instance of a virtual machine (VM). So, it will have virtual USB ports, virtual network connections, a virtual processor and so on, each of which will use up resources of the real, 'physical' machine.

Each VM instance will need to run an operating system and whichever applications it requires, as will the physical machine. In principle, it stands to reason that the total load on the physical processor at any moment in time is going to add up to the sum of all the OS'es, applications, device drivers, virtual machine management tools and whatever else is running, whether they are on a physical machine or a virtual machine.

With this in mind, a question we are often asked is whether anti-virus software should be installed on the physical machine, or in each virtual machine instance. At first glance you'd think...

Continuing his video blog, Symantec’s EMEA CTO, Darren Thomson talks about Virtualization in this three minute video and some of the reasons why customers are doing this.  Cost savings, agility, consolidation and a step towards the cloud are discussed along with Symantec’s view across the areas of risk such as: storage, data protection, HA/DR, security and virtual desktop.

While it may not be the answer to everything, desktop virtualization offers a good solution for certain usage models, such as where access needs to be restricted to certain information or services, or where desktop management needs to be centralized. In the model, virtual instances of desktops send display information to remote screens, even though the processing is actually taking place on a server.

The model can put strains on the physical IT architecture, however. To avoid bottlenecks, it helps to have an understanding of what's going on in the underlying server, storage and network environment. As well as visibility on what’s running on each virtual machine, and how much resource it is consuming.

This brings us to desktop antivirus software which, like any other package, is going to be contending for processing cycles. With the best will in the world, if a hundred virtual desktops are running on the same server and accessing the same storage, and each...

Blog by Robert Mol, Director Product Marketing EMEA:

I’m currently defining some interesting debate topics for a “Consumerization of IT” roundtable discussion taking place in Brussels on December 2nd. This debate, which will be joined by a group of enterprise IT executives may well become a very lively debate on priorities, or we may find the usual reluctance to discuss the rather typical analyst assessment of the market for mobile technologies.

The term 'sprawl' seems to be gaining momentum in IT circles. The culprit, we are told, is virtualisation: while creating, duplicating and even cloning new virtual machines may be much simpler than procuring their physical equivalents, organisations can end up with so many of the things that they start causing management problems. IT isn't straightforward to manage at the best of times, and the usual issues of operations, patching and licensing can quickly get out of control if the number of systems gets out of hand.

One area in particular that can suffer problems is backups, and it's not rocket science to work out why. Backups require transfers of sometimes-large quantities of data, from system, application and user repositories: more machines equals more data to be transferred, which can increase pressure on physical server and network interfaces particularly if everything sis being backed up at once. Lose control of the systems in a sprawl situation, and...

New blog by Darren Thomson, Chief Technology Officer, EMEA

As I meet Symantec customers and partners to talk about some of the impacts that virtualization, mobile and cloud computing are having on their businesses, I hear time and time again about the importance of information and about the fact that the governance and security policy that surrounds information will be key to ensuring successful transitions to new computing and service delivery models.
