Virtual Fragmentation Should Not Result in Network Fragmentation
Multiple goals = multiple hypervisors. This complicates things a bit, doesn't it?

It is quite difficult to find any environment that is truly homogeneous today. Even home networks, which at one time may have been "all Windows" or "all Linux" today are a mixture of mobile device, Apple, and Windows-based products. As networks grow, the heterogeneity of its infrastructure increases, with a variety of switches, servers, and platforms adding to the mix of end-user computing devices.
Virtualization is no different. As the uses for virtualization technology continue to expand to various application functions, the heterogeneity of the virtual platforms used is also growing. The 2013 Virtualization Management Survey from Information Week indicated over a third of respondents have more than one hypervisor in use today. In the next two years that number is expected to increase to nearly half of all organizations leveraging multiple hypervisor technology.
The reasons for that divergence are varied, the same survey shows. Some organizations use different virtualization vendors for server virtualization than they do for desktop. Others cite hardware compatibility for legacy hardware as a reason for using multiple hypervisors and so on.
Whatever the reason, the trend seems clear: heterogeneous virtualization is increasing, and eventually that divergence will have an impact on network infrastructure.
With multiple hypervisors in use, it is increasingly important that the network infrastructure is equally capable of providing the appropriate services for all hypervisors in use. This is particularly true as we begin to see an increase in adoption of SDN-related protocols such as NVGRE and VXLAN to virtualize the network. Protocol incompatibilities will become problematic for organizations attempting to leverage such technology in conjunction with multiple hypervisors due to a lack of ubiquitous support. Either organizations must standardize across inter-dependent and integrated services to ensure compatibility at the network layer or they must plan to put into place protocol transition capabilities in the network itself, much in the same way "gateways" are used within IPv4 to IPv6 transitional architectures.
Too, virtualization of the network through SDN-related protocols will be primarily confined to within the data center. Users accessing those services will not be doing so using these protocols, making the two networks nearly incompatible. A bridge between the traditional and virtual networks must exist, and it must be agnostic to ensure seamless communication.
Virtualized solution architectures such as those associated with VDI that require specific network infrastructure will also be trouble for organizations, as it limits their ability to share the cost of infrastructure across multiple projects and applications. Agnostic infrastructure, capable of providing equal levels of delivery, security and availability to any IP-based application – including those virtualized - will offer a more cost-effective and operationally consistent approach to managing a heterogeneous virtual infrastructure.
What would be detrimental to the adoption and advancement of virtualization in the data center – whether in the application or network infrastructure – is to create even more complex networks consisting of multiple paths that are dependent on a given hypervisor and SDN-related technology. The disruption of the network and application services should be kept to a minimum and the network architecture kept as simple as possible to avoid the introduction of additional (and unnecessary) points of failure.
By leveraging a strategic point of control within the network with agnostic infrastructure capable of being a bridge not only between traditional and virtual networks but also between competing virtual network implementations will eliminate complexity while offering the operational consistency that reduces both cost and risks.
Fragmentation of virtualization in the application infrastructure should not result in fragmentation of the network.

As we enter a new year, it is time to look back over the past year and resolve to improve upon it. In 2014, we will see more service providers resolve to add more personalization in enterprise technology. Below are seven predictions about what will drive this trend toward personalization.
IT organizations face a growing demand for faster innovation and new applications to support emerging opportunities in social, mobile, growth markets, Big Data analytics, mergers and acquisitions, strategic partnerships, and more. This is great news because it shows that IT continues to be a key stakeholder in delivering business service innovation. However, it also means that IT must deliver new innovation despite flat budgets, while maintaining existing services that grow more complex every day.
Cloud computing is transforming the way businesses think about and leverage technology. As a result, the general understanding of cloud computing has come a long way in a short time. However, there are still many misconceptions about what cloud computing is and what it can do for businesses that adopt this game-changing computing model. In this exclusive Q&A with Cloud Expo Conference Chair Jeremy Geelan, Rex Wang, Vice President of Product Marketing at Oracle, discusses and dispels some of the common myths about cloud computing that still exist today.
Despite the economy, cloud computing is doing well. Gartner estimates the cloud market will double by 2016 to $206 billion. The time for dabbling in the cloud is over! The 14th International Cloud Expo, co-located with 5th International Big Data Expo and 3rd International SDN Expo, to be held June 10-12, 2014, at the Javits Center in New York City, N.Y. announces that its Call for Papers is now open. Topics include all aspects of providing or using massively scalable IT-related capabilities as a service using Internet technologies (see suggested topics below). Cloud computing helps IT cut infrastructure costs while adding new features and services to grow core businesses. Clouds can help grow margins as costs are cut back but service offerings are expanded.

What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse.” In 2012, Infochimps (now CSC) leveraged its early use of stream processing, NoSQLs, and Hadoop to create a design pattern which combined real-time, ad-hoc, and batch analytics. This concept of combining the best-in-breed Big Data technologies will continue to advance across the industry until the entire legacy (and proprietary) data infrastructure stack will be replaced with a new (and open) one.
While unprecedented technological advances have been made in healthcare in areas such as genomics, digital imaging and Health Information Systems, access to this information has been not been easy for both the healthcare provider and the patient themselves. Regulatory compliance and controls, information lock-in in proprietary Electronic Health Record systems and security concerns have made it difficult to share data across health care providers.

Everyone talks about a cloud-first or mobile-first strategy. It's the trend du jour, and for good reason as these innovative technologies have revolutionized an industry and made savvy companies a lot of money. But consider for a minute what's emerging with the Age of Context and the Internet of Things. Devices, interfaces, everyday objects are becoming endowed with computing smarts. This is creating an unprecedented focus on the Application Programming Interface (API) as developers seek to connect these devices and interfaces to create new supporting services and hybrids. I call this trend the move toward an API-first business model and strategy.
We live in a world that requires us to compete on our differential use of time and information, yet only a fraction of information workers today have access to the analytical capabilities they need to make better decisions. Now, with the advent of a new generation of embedded business intelligence (BI) platforms, cloud developers are disrupting the world of analytics. They are using these new BI platforms to inject more intelligence into the applications business people use every day. As a result, data-driven decision-making is finally on track to become the rule, not the exception.
