Nexus 1000V and Virtual Network Overlays Play Pivotal Role in Software Defined Networks

June 14, 2012 at 4:00 am PST

There’s an incredible amount of hype and excitement these days around Software Defined Networking (SDN), which promises to herald in a new age of flexibility, business agility and automation to our existing data center and campus networks. Since there are very few, if any, SDN networks in production environments today, though, we know there are a lot of implementation details to work out before the industry achieves the lofty benefits of network programmability. Cisco opened its kimono this week on its strategy around programmable networks (an even broader concept than what we believe the traditional definition of SDN is), called Cisco Open Network Environment. (Get Omar’s take on Cisco ONE).

Open Network EnvironmentIf you are like a lot of people, you might think that SDN is synonymous with OpenFlow, the leading standards-based approach for SDN today. However, we are already seeing folks across the industry extending the SDN vision beyond what OpenFlow is currently envisioned to do, so we think the definition of SDN will probably evolve over the next year or so to include additional programming models and protocols. Cisco ONE, for example, includes three approaches to network programmability: 1) our own onePK set of API’s to Cisco network operation systems and devices, 2) a portfolio of agents and controllers that will support OpenFlow, among other things, and 3) our Nexus 1000V-based portfolio for building virtual network overlays.

Lippis Video Introduces Cisco’s Network Virtualization Portfolio

February 6, 2012 at 9:40 am PST

Nick Lippis of the Lippis Report sits down with Prashant Gandhi, Cisco’s Sr. Director of Marketing for Virtualization in our Server Access and Virtualization Business Unit, to discuss all things virtual in this new video podcast. Prashant does a great job showing why Cisco’s network virtualization stack is the most complete in the industry, including the Nexus 1000V virtual switch, the Virtual Security Gateway (VSG), the ASA 1000V Cloud Firewall, the virtual Wide Area Application Services (vWAAS) WAN optimization solution, Network Services Manager (NSM), Virtual Network Management Center (VNMC), and the Nexus 1010 and new 1010-X Virtual Services Appliance. When you include recently announced technologies like VXLAN and support for the Microsoft Windows Server 8 Hyper-V hypervisor later this year, a great overview video like this can help you keep up with all the recent innovations.

Forrester Report on Virtual Security Adoption in the Data Center

January 18, 2012 at 4:38 pm PST

Forrester logoForrester Research released this week a new Technology Adoption Profile (TAP) report on Virtual Security in the Data Center. The research report, which was commissioned by Cisco, asked enterprise data center owners how they were currently addressing security and compliance issues on their virtual applications, and how they anticipate incorporating new technology going forward.

Fundamentals of High End Firewalls

November 29, 2011 at 4:25 pm PST

We had fun turning out a few new security oriented fundamentals that we always hope you enjoy.  This one firewall animation is very complimentary to a full TechWiseTV show we recently released..you can see it embedded just after the jump.  Nothing in networking is ever really an apples to apples comparison but it seems like firewall vendors are more full of hot air than anyone.   Read More »

Cisco ASA 1000V: The Cloud Ready Firewall

November 28, 2011 at 11:57 am PST

Juniper Reality

In this show, we cover the new ASA 1000V and how this security family represents the oldest yet most future ready security platform.

What is the relevance of a Firewall in today’s modern world where security must encompass every part of increasingly distributed operations? What is really meant by a Cloud Ready Firewall?  What the heck is this new ‘virtual ASA’…didn’t we already have the Virtual Security Gateway?  Perhaps its all just marketing hype…

Or not.

In my estimation, the cloud is overhyped in the short run, but underestimated in the long run.  Every enterprise is now exploring some aspect of a cloud based service model – whether this represents you now or in the future, the notion of a flexible security solution remains important.  Incredible advances for data center infrastructure with the flexibility and speed enabled by the virtualized tools we are all now using – MUST be accompanied by equally capable security tools.

The original maxim still rings true: Security must be addressed at every layer.

Questions we must answer:
