The ROI from virtualizing tactical applications is driving by the consolidation in the number of physical servers needed once tactical workloads are virtualized. However, when virtualizing Tier 1 or business critical applications, it is likely that significant consolidation in the number of cores per workload is not possible – leading to the requirement to find a new way to cost justify these projects.

Virtual Computer recently announced the availability of their NxTop product for free for up to five users. NxTop combines centralized virtual desktop management with a “bare-metal” client-hypervisor to make managing many desktops as easy as managing one. But, you may ask, what can a client side hypervisor do for me? The answer – solutions such as Virtual Computer’s NxTop can be utilized to effectively manage your desktop environment, provided they have a functional management interface. That said, bear in mind this is a developing technology, but it is a technology that offers you the opportunity to manage your desktops with virtualization without the larger infrastructure requirements of VDI but that doesn’t mean to say it wholly replaces SBC solutions: but it is a useful option to consider.

Appsense’s development of User Rights Management and User Installed Applications offer products that you can deploy to give additional rights to users so that they can work effectively without being a drain on IT, or IT being a millstone to them. How will such functions impact your business?
Can you transform your desktop estate by migrating to VDI solution and expect that “savings will be made”? You should ask not what you can do for VDI, but what VDI can do for you. The process of transforming your desktop needs to begin with understanding what each user has in their workspace. Being able to minimize your desktop device spend should not come with increased costs due to complexity and lost productivity. Be sure you fully assess what it is that you have now before considering transforming your environment.
Citrix Xenclient enters the bare metal hypervisor for desktops devices market and challenges the incumbents – Neocleus and VirtualComputer. As a solution to reducing management costs and improving the user experience such a funtion is undoubtedly a contender to change the way you think about your PC lifecycle management.
Virtualizing Tier 1 business critical applications is a challenge for many enterprises due to the resistance to the concept on the part of applications owners and their constituents. Service Assurance for these applications is required in order for their owners and their users to go along with virtualization. Service Assurance requires the integration of Applications Performance Management, Configuration Management and a new category of solutions like VMTurbo to dynamically allocate resources based upon their highest and best use.
Does an evaluation for a virtualisation project need to be only an exercise in understanding if X hosts will on Y servers? Will you be able to to virtualize every service you deliver? Are new applications required? What are your existing service-levels and requirements across your application portfolio? In most enterprises today, IT is a cost centre not a profit centre. Business units often want detailed involvement in implementation plans, asset purchases and ownership: it is not unusual that requests for applications come in terms of functionality – not in terms of service levels. With their release of Workspace iQ, Centrix Software appear to be unique in endeavouring to aggregate information that can be used to deliver data that can help provide IT with improved costing information without relying on specific vendors solutions to be in place.
Both Presentation Virtualisation and Desktop Virtualization can be used to provide a Windows desktop experience and to deliver applications, such as Microsoft Office, not only to desktop hardware that might be older but to non-Windows desktops (e.g. Linux PCs. Apple Macs or Thin Client devices). Both virtualization technologies can help your business centrally manage and support applications allowing you to make savings in improved productivity. Moreover, such centralization technologies can extend applications beyond your network – to home workers, to contract staff, to roaming users – and to an ever growing set of devices – be it a netbook, a Windows Mobile device or an iPhone.
