Making a Case for Programmatic Interfaces in Existing Service Provider Networks – Going Beyond Software Defined Networks

The communications industry has come a long way from fixed, inflexible telephone service optimized for voice to dynamic IP-based connections offering converged voice, data, and video capabilities. Now, both residential and business users are increasingly more mobile and distributed, as are the cloud-based services, applications, and content they want to utilize. Service providers must therefore support a more diverse customer base with more distributed content and applications across multiple geographies, yet still maintain a secure, reliable, and consistent quality of experience regardless of device and physical location.

In the face of greater traffic demands and the risk of becoming lower-margin “commoditized pipes,” network operators must react to three key challenges: Read More »

More VMworld Redux: Customers Love Cisco Nexus 1000V

September 7, 2012 at 4:00 am PST

VMworld last week was a great success for Cisco (well, if you don’t count the #v0dgeball challenge). Leading up to the show we announced that the ASA 1000V cloud firewall was shipping, we announced a new major release of the Nexus 1000V virtual switch, and a new version of our Virtual Network Management Center.

Talking to customers is always the best part of the show, hearing what their challenges are, and positioning our technology to fit their needs. On Wednesday, I met up with Paul O’Leary, an Infrastructure Specialist with the international law firm of King & Wood Mallesons. Paul is a big fan of the Cisco Nexus 1000V and shares why his networking team loves it so much, and how it consistently saves them time in managing their network policies.

We showed Paul some of the features coming out in our next release, like the vCenter plug-in, and vTracker for viewing statistics on the virtual fabric, et al., and he was really excited. Anyway, Paul was good enough to let us share his thoughts with you rather spontaneously, so without any further ado, let’s roll the video:

But wait, there’s more…  Read More »

VMworld 2012 Redux: Cisco Partner Presidio Talks Nexus 1000V, Virtualization and Cloud

September 5, 2012 at 9:33 am PST

Last week during VMworld in San Francisco, I had the chance to sit down with Steve Kaplan (@ROIdude), VP of Virtualization and Cloud, at Presidio, one of Cisco’s largest reseller partners. Steve is an author and industry speaker, especially on financial and ROI impacts of technology. He gives us a great perspective on how his firm is working with customers to get them cloud ready, and some of the virtualization trends he’s seeing with customers and in the industry.

In addition to the video, Steve and a colleague at Presidio published a blog on their web site about why they see customers moving to the Nexus 1000V virtual switch as the foundation for their cloud environments, and what challenges it’s helping them to overcome. Unfortunately, we didn’t get a chance to talk much about the new trends in Software Defined Networking (SDN), programmable virtual network overlays, or OpenStack, but Dom Delfino covers some of these related topics as well in another great video recorded at VMworld last week.

For those of you that think all of our Cisco video productions are tightly scripted, well rehearsed, finely edited affairs, this will convince you otherwise. We tried to keep it pretty interactive and we had a lot of fun doing it. I think you’ll find the insights valuable.

Nexus 1000V Provides Cloud Switching to New Windows Server 2012 Platform

September 4, 2012 at 4:39 pm PST

Windows Server 2012 logoToday marks the general availability of the eagerly-awaited Microsoft Windows Server 2012 platform.  According to Microsoft, “Windows Server 2012 redefines the server category, delivering hundreds of new features and enhancements spanning virtualization, networking, storage, user experience, cloud computing, automation, and more.”  Earlier Cisco blog posts discussed how Cisco has collaborated with Microsoft to achieve Windows 2012 certification for our UCS servers, as well as integrating our management tools into Microsoft System Center and PowerShell.

Microsoft Build Conference 2011 - Demo of Nexus 1000V virtual switchIn this post, I’d like to highlight the integration of the Nexus 1000V virtual switch into the Windows Server 2012 platform, and particularly the Hyper-V hypervisor. We have been working closely with the Windows Server 2012 team for the past few years towards this goal, and announced Nexus 1000V and VM-FEX support for it at the Microsoft BUILD conference last year.  Read More »

OK, Now What?

August 29, 2012 at 10:55 am PST

 “Each success only buys an admission ticket to a more difficult problem.”

-- Henry Kissinger

Following the early successes with network programmability,  the natural question that arises is “where do we go form here?”  Certainly some good things have been accomplished, but in many ways the real work is just beginning. David Ward just posted some musings on where we go next with programmatic interfaces for the network--its a good read and I encourage you to check it out.
