Asking ‘What’s the Point of SDN?’ and the Impact on Adoption

Summary Bullets:

  • Many enterprises are struggling to find a reason to invest in SDN when what they have in place works well enough.
  • There will not be a killer app for SDN.  Rather, enterprises will adopt SDN as their data centers needs evolve over time.

I recently attended and presented at the SDN and OpenFlow World Congress in Bod Homburg, Germany, and while I was there, I had a chance to talk to some enterprise IT attendees who were investigating SDN for their organizations.  The common question through most of the discussion was: “Why should I use a SDN?”  Luckily, I started my talk with that very question.

What’s Next for UC and Virtualization Software in Private Clouds

Summary Bullets:

  • How UC software deployed in private clouds will change
  • What will change: Support for multiple hypervisors, a variety of server hardware, and advanced management features

Continuing on the topic of unified communications and virtualization from my previous IT Connections blog, UC solutions’ support for server virtualization is facilitating their deployment in private cloud environments. This has taken the form of Cisco, Siemens Enterprise, Mitel, and others adding support for VMware vSphere on their various UC and contact center platforms, while Avaya supports Citrix XenServer. This luxury of vendors being able to pick and choose which server virtualization platform they support is likely to be short-lived. Their widespread support for VMware vSphere is understandable. VMware commands a large share of the market, so choosing to support VMware means that a large number of enterprises will be able to deploy UC software in data centers. However, VMware is not the only game in town and not all enterprises have standardized on it. As a result, developers of UC solutions will soon need to support other hypervisors as well. Microsoft is ahead in this particular game. When Lync was launched early this year, it included support not only for Microsoft’s Hyper-V hypervisor, but also for VMware and Citrix hypervisors.

Virtualization and UC: Strange Bedfellows No More

Summary Bullets:

  • Server virtualization is available here and now for a wide range of UC solutions
  • Desktop virtualization for UC client software is by and large in the works

Virtualization and real-time communications have traditionally made for strange bedfellows. Yet persistent R&D work among top UC solution and virtualization software developers led to deployment on virtualized servers in a data center as a standard option for PBX call control software. Mitel started the ball rolling, working closely with VMware to develop a version of the vSphere virtualization platform capable of supporting real-time communications software. Server virtualization is now a checklist item for both UC and contact center software, with Aastra, Avaya, Cisco, Microsoft, Siemens Enterprise and to a certain extent, ShoreTel, all supporting it.
