VMworld 2011 – Soni Jiandani Sums Up Cisco Innovations

Before going on to an interview on SiliconAngle.tv and speaking at a Super Session on “How Cisco and VMware Collaborate to Build the Cloud”, Soni Jiandani gave me a couple of minutes to sum up the Cisco innovations announced and on display at VMworld 2011.

Some things Soni mentions:

A New virtual ASA: On Full Display at VMworld in Las Vegas

August 29, 2011 at 10:32 am PST

At VMworld this week in Las Vegas, Cisco will be providing a preview of a virtual implementation of our ASA security appliance. A “preview” implies that we aren’t ready to announce ultimate pricing or availability, but we are demonstrating a strategic direction for the ASA product line. Earlier, I alluded to important new advances in our virtual security story upcoming at VMworld in the comments section of a recent blog post I wrote responding to HP criticisms of our Virtual Security Gateway (VSG) product.

With security concerns being the most frequently cited obstacle to large scale virtualization projects and adopting cloud computing models, Cisco will be greatly enhancing its industry-leading virtual security infrastructure with this product. The new virtual ASA introduces a wide range of security services that have not been available from Cisco before in a virtual form factor. The virtual ASA will enable more sophisticated security policies that better align with business and compliance needs in the virtual data center.

Some of the key aspects of this new virtual ASA product:

  • The ASA family is one of the most deployed and trusted security products in the industry, with over 15 years of security experience and more than 1 million appliances installed, and now is available in a virtual form factor for greater flexibility in the data center
  • Virtual ASA runs the ASA feature set, so important capabilities such as VPN , NAT, and much more will be available in addition to firewall capabilities
  • The Virtual ASA will run on top of the Nexus 1000V virtual switch, fully leveraging the VM and traffic visibility provided by the Cisco virtual fabric, as well as optimal traffic steering to the security node from the VM and virtual switch

Rather than replacing our VSG virtual firewall, the virtual ASA will be a strong complement for the current VSG capabilities. The virtual ASA includes security functionality most often deployed at the edge of an organization and the edge of the data center. As such, it is better suited for North-South traffic into the data center and virtual applications. VSG, with its greater visibility to VM-specific and application attributes, enforces security policies between applications and virtual machines, and is more East-West traffic oriented.

Across the whole ASA product line, customers will be able to get consistent functionality, management and policy enforcement across all form factors (stand-alone appliance, modular blade, and now virtual instances). And with Nexus 1000V integration, Virtual ASA customers will also get consistency in management, provisioning and service routing with Cisco’s other virtual services including VSG and vWAAS. At a minimum, this should alleviate all objections that we just offered a virtual firewall and not other key security services.

If you are in Las Vegas next week, we encourage you to come by the Cisco booth (#700) for a look. If not, stay tuned for more details…

All Around the Podcast World – Cisco UCS, Nexus, VDI/VXI & Intelligent Automation

Within the Data Center marketing organization, we spend quite a bit of time focused on activities that announce new products or solutions, as well as educating customers, partners and analysts. Sometimes this is done via launches and other times it’s at events like EMC World 2011, SAP Sapphire, Citrix SynergyCiscoLive 2011 or the upcoming VMworld 2011 (Cisco is a Diamond-level Sponsor). But once that information leaves our hands and gets out into the community, it’s important for us to remember that it’s often discussed, dissected, and evaluated by a broad range of IT professionals.

Over the past few weeks and months, Cisco Data Center technologies have been features in several industry podcasts.

And of course, don’t forget this list of Cisco UCS Evangelists from every part of the world. Read More »

VSG: Vive la difference! A Tutorial for HP

July 27, 2011 at 11:06 am PST

One of the things I admire about Cisco marketing, and I think generates a lot of respect for us from our customers, is how we approach competitive marketing. Most importantly, we hardly ever do it. Sure, we arm our sales teams with specific comparison data, but it’s rare we feel the need to compare ourselves publically or to bash competitors. When you bash a competitor, it really only serves to give them credibility, and highlights that they must be doing something important to occupy your mindshare, or that of your customer’s.  Occasionally though, we are faced with not only having to take the gloves off a little more, but responding to the inevitable FUD that gets thrown our way.

This brings us to a blog post written by HP about Cisco’s Virtual Security Gateway (VSG), which unfortunately contains a number of inaccuracies and misrepresentations of our product that we have to clear up.

Let’s start with this example:

Cisco has a product called the Virtual Security Gateway (VSG) for the Nexus 1000V Series. It is a virtual firewall that lets you enforce policy and segmentation virtual environments. All associated security profiles are configured to include trust-zone definitions and access control lists (ACLs) or rules. They also support VM mobility when properly configured. If there’s one thing the company is good at, it is those good-old ACLs developed back in the early 90s!

The strength of VSG’s firewall capabilities is its awareness of the virtual machine environment, and specifically the ability to write firewall rules based on the attributes of the virtual machine, attributes such as the NAME of the VM. This gives tremendous power to establish policies in virtual environments, such as logically isolating tenants running on the same machine, or separating VMs based on operating system or application type in virtual desktop environments, a use case I wrote about earlier. To imply VSG is enforcing good-old ACL’s from the 90’s is disingenuous at best. Read More »
