Hybrid cloud: Who's in control when public and private clouds collide?
This article is part of the Network Evolution issue of December 2013 Vol. 4 / No.6
The exponential growth of hybrid cloud leaves IT shops grappling with crucial questions, including: What is the role of the enterprise network in this shared scenario? Is software-defined networking (SDN) suddenly necessary? And perhaps the trickiest of all -- when enterprise IT teams and service providers share environments, who's responsible for what? Hybrid cloud infrastructure is defined by the U.S. National Institute of Standards and Technology as: "A composition of two or more distinct cloud infrastructures -- private, community or public -- that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds)." The key here is that "hybrid cloud is more than just a public cloud and a data center. Portability and the commonality of applications and data are the things that really distinguish it," said Mathew Lodge, vice president of cloud services for VMware. On the networking front, "folks are ...

There's plenty of potential in unifying public and private cloud resources, but there are also hybrid cloud challenges that make the IT team question its role.
A number of enterprises are moving beyond premises-based UC hardware, choosing cloud-based UC technology for reasons as varied as their business models.
IPv6, SDN and the cloud seem like separate initiatives, but they are interdependent. SDN and IPv6 will enable cloud agility. The good news is they are also complementary.
Columns in this issue
Engineers need to implement major network change for IPv6, SDN and hybrid cloud. But they're learning they'll have to manage the old and the new at once.
New vendors are pushing network architectures that decouple software from hardware and run on bare metal switches with merchant silicon. Have we reached the x86 era in networking?
