Hybrid cloud: When public and private clouds collide
This edition of Network Evolution looks at how companies are mixing old and new technology as they transition to the new technology -- but is it the best approach? For example, very few IT shops will move entirely to running IPv6 networks; instead they’ll manage dual IPv4/IPv6 environments. Alternatively, network managers should look beyond moving from IPv4 to IPv6 and consider redesigning their networks for both IPv6 and SDN.
However, the same kind of phenomenon is playing out in the cloud, where enterprises look to use both private and public cloud. They need tools to help them manage both on-premises and hosted clouds, as well as legacy equipment.
In the end, the trick is in figuring out how to manage the transition to new technology without losing everything. This issue provides insight into how organizations chose to implement new technology -- whether incrementally or all at once -- to help others determine which path is best for them.

Features in this issue
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?
