Executive Overview Hybrid IT vs Hybrid Cloud Today’s CIOs are responsible for variety of application and infrastructure services (dedicated and virtualized) and in many cases are on the path to offering Private Clouds. In addition the same IT organizations are managing a portfolio of service providers for with Public Cloud services and Management Services. The combination of all of these delivery options is defined as Hybrid IT. So in effect most modern IT organizations are already Hybrid IT enabled.

Executive Overview Converged Infrastructure Enables Advanced IT Information Technology continues to evolve at a dizzying rate. With the advent of Virtualization and Cloud Computing the IT industry has taken a new path – bringing together all of the core technologies used in the data center into pre-integrated converged platforms that combine storage, network and compute. These platforms are optimized for a virtualization and shared infrastructure model – moving away from traditional dedicated platforms for individual applications.

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.

Many industry experts call cloud computing the “New IT” because it’s emergence marks a new era in the IT industry. Cloud computing enables rapid delivery and consumption of IT on-demand services in concert with constantly-changing business drivers. Most of the recent hype regarding cloud computing has focused on the technology that enables this new IT model. However, the real source of innovation are new service roles and service management that are part of a recyclable set of IT resource pools to provide IT-as-a-Service. Cloud computing is driving fundamental change in today’s IT organizations. It is the culmination of all that IT was in the past and sets the stage of what IT will become.

While the industry buzz around data center technologies is already dizzying, it’s still managing to become increasingly confusing. Every vendor seems to be laying claim to a new way of approaching the data center, cloud computing, and consumption models. As Presidio has transitioned from the solutions integrator of prior years to a cloud integrator, our emphasis is on helping clients filter through all the noise to understand where the new technologies can make a real business impact. As we sift through the morass, we get to see that what really matters are the services being offered to businesses and users. Our ultimate objective is to help our clients transition their data centers from inefficient islands of technology to unified, dynamic environments and resource pools – whether on premise or located in public clouds. The old data center model transforms into one which provides IT-as-a-Service.
