The Virtualization Practice

Business Agility

Business Agility covers using the technical agility delivered by virtualization and cloud computing to improve business agility, performance and results. This includes the agility derived from the proper implementation of Agile and DevOps methodologies, the agility derived from proper application and system architectures, ...
the agility derived from the proper implementation of Infrastructure as a Server (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) clouds, the agility derived from proper monitoring of the environment coupled with a process to resolve problems quickly, and the agility derived from have continuous availability through the use of high availability and disaster recovery products and procedures in place.

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.

Is Virtualization Solutions Delivery Fundamentally Changing?

It is clear that once virtualization started delivering hard dollar CAPEX and OPEX savings to IT executives that these executives wanted this trend of “more for less” to continue. Most IT organizations are far from 100% virtualized, and there are still substantial cost savings to be gained from further virtualization. However, forward thinking vendors (like Cisco, EMC, and HP) see the handwriting the wall and are taking steps now to be able to deliver solutions at reduced costs to their customers.

Indeed a challenge in migrating to a Hosted Virtual Desktop (HVD) solution is what to do with existing devices. Citrix’s High Definition User EXperience (HDX) technologies for example, typically relies on the end device supporting a Microsoft Windows operating system to deliver the best user experience. If that is the case, how will you manage the end device that delivers the user’s HVD? Vendors such as DevonIT, Igel, and 10ZiG would naturally suggest you replace your traditional PC with a Thin Client: vendors such as PanoLogic, Teradici and Wyse would highlight the advantages of Zero Client devices – yet moving away from existing devices is a costly exercise in terms of providing replacement devices. And indeed – still does not address off-line working.
