The traditional physical data center consists of a hodgepodge of equipment, tools and systems—all driven by project-based funding. This budgeting anachronism is an anathema to a virtualized data center that utilizes shared resource pools and can absolutely derail a planned transition to a private cloud model. When implementing a private cloud solution, organizations should transition to a chargeback model.

A CIO recently told me that one of his business units was threatening to move all of its servers to Amazon Web Services. This bears out a statistic I read not long ago claiming that over half of the virtual machines on AWS are now purchased directly by business units via credit card. IT, though, remains responsible for the performance integrity and regulatory compliance of all of the organization’s servers, wherever they reside.

Organizations frequently evaluate virtual desktops as replacements for physical units. They expect to achieve the same type of results as when virtualizing servers. But unlike servers, virtualizing desktops often has a less obvious ROI and directly impacts hundreds or thousands of users with differing expectations and perceptions. A virtual desktop deployment without a strategic approach is more difficult to justify, and, even if implemented, more likely to stall out at the pilot phase or fail completely. It also misses the opportunity for accelerating a successful transition to cloud computing.

The IT industry is once again undergoing another great transformation. Cloud computing, by replacing operational heroics with business driven speed and agility, will spur a lot of innovation. As an IT leader for your organization it is important you ask yourself, “Are we ready? Are we, as an organization, well-suited or ill-suited for the future of IT, and can we afford not to be ready?”

The following is one of a collection of articles that addresses strategy around hybrid cloud architecture and IT as a Service. While the hybrid cloud model is widely extolled in both the media and by industry manufacturers, many organizations find themselves challenged to effectively utilize both private and public cloud components. A successful hybrid cloud requires internal procurement and process changes that enable IT-as-a-Service along with a methodical approach to ensure adequate performance, reliability, security and compliance of off-premise workloads.

A private cloud is built upon a virtualized network, along with storage and compute resources. Many virtual networks are overlaid on top of the shared physical network, logically separating tenants on the shared resources. One challenge is that the physical network lacks visibility into the topology of the overlays. A second obstacle is that network overlays utilizing standard vSwitches do not allow for security and network policies to live-migrate with VMs.
