Today, I wanted to point out a couple of great resources to develop a deeper understanding of Cisco’s virtual switch, the Nexus 1000V.
First, we were excited to have Prashant Gandhi, our Sr. Director of Product Management for the Nexus 1000V, be invited onto the latest Packet Pushers Podcast, hosted by Greg Ferro. If you aren’t yet familiar with the PP Podcasts, they are an entertaining technical dive into a wide range of networking concepts with guests from vendors as well as large IT organizations. Greg’s expertise lies in the data center and with all things networking, including virtualization and L4-7 application services. In this podcast, all about the Nexus 1000V, Greg, Prashant and the other co-hosts talk about the architecture and deployment issues. There’s an extensive comparison of Cisco’s 802.1Qbh virtual Ethernet bridge protocol with the 802.1Qbg proposal from HP, VEPA. Listen to the full podcast here.
Greg had made an earlier plea on his blog that he wasn’t getting enough Cisco guests. We were happy to help out and enjoyed the interaction. We talked about having Prashant back on a future show to talk about vPath and the Virtual Security Gateway (VSG), the virtual firewall running on the Nexus 1000V. We look forward to that as well.
For a deeper, hand-on dive into the Nexus 1000V, nothing beats the Cisco CloudLab (http://cloudlab.cisco.com). We’ve set up an online workbench configured with all the tools and software to play around with the virtual switch yourself. Cisco Cloudlab is available to folks outside Cisco, but you will have enter the name of a Cisco employee sponsor to approve access. There are a number of lab exercises you can walk through to get a general overview, install or upgrade the Nexus 1000V, as well as VSG.
Based on the positive feedback I received from my Cisco UCS videos, I decided it was time to tackle a slightly more complicated set of topics. While it’s fairly easy to come up with a set of keywords that spell out C-I-S-C-O, sometimes it’s valuable to take off the training wheels and go a little broader. So in today’s video, we combine the simplicity of M&Ms with the complexity of VMs. How do we take technology that provides tremendous value to customers and explain it in a way that’s fun and easy to replicate? Well, let’s see what happens… Read More »
The Unified Network Services (UNS) portfolio of Layer 4-7 services (such as ACE and WAAS) also includes Cisco’s data center security solutions. A critical part of that security portfolio is our virtualization-aware firewall solution, Virtual Security Gateway (VSG). In a series of upcoming blog posts, I’ll be sharing a few use case scenarios that our customers are implementing with VSG.
For those of you new to VSG, I’ll point out that VSG’s role is to act as a virtual firewall between zones of virtual machines. Isolating traffic between VM zones has been very challenging prior to VSG because: 1) security policies have to be enforced between VMs running on the same server or same virtual switch (where there’s no place to put a firewall), 2) VMs move all around the network and the security policies (as enforced in the firewall) must follow the VM, and 3) the need to maintain segregation of duties for compliance purposes between the security and application server teams, where security is potentially enforced inside the virtual server.
CiscoLive London was an incredible trip and gosh it was only 30 days ago – our first little project out of that voyage is TechWiseTV85 our latest episode on Data Center technologies. Data Center Optimization: The Next Stage is now available for your viewing pleasure in our ‘still has that new website smell’ environment we affectionately call the CVC (Cisco Virtual Connection).
This show was another exercise in self-restraint as the DC team had brought out an amazing selection – if we were hoping that a global show would mean a smaller show…we were out of luck.
I’ve written before (here, here, and here) that Cloud Computing is more than some cool software running on a server. Sure, the applications are the sizzle on the steak (+ all the marketing terms -- dynamic, elastic, on-demand, etc.), but there’s a little more to it than that. A user needs to access the application, get the information quickly (or sent it information), and feel confident that the information was delivered securely. The application doesn’t always know what type of device will access it (PC, Mac, Browser, Tablet, Smartphone, etc.), so it can’t be 100% sure it’ll deliver the best user-experience. And users will demands that applications continue to run regardless of the mobile device’s location. All those demands on applications get a lot easier, and in some cases require, an intelligent network providing the infrastructure.
But people often forget those details because they have become so accustomed to a robust network always being there. They might struggle to define the value of that network, just as Kodak did in defining “original technology” in the famous Mad Men episode (Carousel).
