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).
If 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.
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 »
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…
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.
