The Virtualization Practice

Tag Archive for Cisco

In the first Virtualization Security Podcast of 2011, we had Brad Hedlund with us once again. Not to talk about the Cisco Virtualization Security Gateway (VSG), but about the security of what I call physical-virtual devices that provide network virtualization within the hardware. Or what Brad Called Network ID Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere.

The desktop virtualization year opened with a bang at CES with the explosion of vendor announcements introducing the next generation of mobile tablets. The obvious winner this year being Apple and the iPad but with many more vendors showing off Windows-based tablets including HP, Archos and Pegatron, as well as Android tablets from manufacturers such as Archos (again), Compal, Dell, HP (again), and Motorola. The key challenge of course being the delivery of existing enterprise applications onto these platforms, something that’s desktop virtualization and presentation virtualization is ideally suited for. The inescapable consequence of this was a steady stream of announcements from Citrix, VMware, and Wyse as they leapfrogged each other’s announcements on availability, functionality, and usability of their respective mobile tablet client offerings. The level of competitiveness here producing major benefits for potential adopters as each strove to outdo the other in terms of user experience innovation and performance.

It is the last few days of the year and time for a review of virtualization 2010. Although VMware was founded in 1998 it was not until 2001 that I first heard of VMware and played with the workstation product to be able to run different flavors of Linux. So for me, 2010 closes out a great year in virtualization as a whole as well as a decade of virtualization and what a ride it has been.

In the last Virtualization Security Podcast on 12/16 we had with us James Urquhart who manages cloud computing infrastructure strategy for the Server Provider Systems Unit of Cisco Systems. Author of the popular C|NET Network blog, The Wisdom of Clouds. James shared with us some of his Wisdom over the hour. The discussion covered what is preventing people from Entry into the Cloud and why private and hybrid clouds are going to stick around for quite a while and are not a passing fad. We answered the question of why people are reluctant to enter the cloud.

Cisco Virtual Desktop Experience

Considering the success of Cisco’s virtualization friendly UCS platform it should come as no surprise to hear that Cisco is intending to extend its data center virtualization footprint to include desktop virtualization as well. However as last week’s announcement of the Cisco Virtualization eXperience Infrastructure (VXI) shows Cisco does not expect a straight repeat of its server virtualization strategy to win the day. While Cisco’s plan to encourage mass adoption of desktop virtualization is based on the same Unified Computing System (UCS) that is behind Cisco’s current server virtualization strategy, it’s approach is distinctly different.

I can remember, in what seems like a really long time ago, about the creation of a new company, Acadia, that will support the coalition of VMware, Cisco and EMC’s vBlock product. I had really long forgotten about the new company that was going to be formed when EMC really started their hiring blitz and campaign to get all the well known talent that EMC could get their hand on. That had been the news and buzz in the industry, as well as a nonstop twitter topic speculation about who was going to be the next person to enroll in Chad’s Army as a vSpecialist. It really appeared that the EMC crew was going to be in the best position to support and sell vBlock technology.

The Cisco-VMware-NetApp (CVN) was discussed on the Virtualization Security Podcast as it pertains to Secure Multi-Tenancy (SMT). This is a major concern that was also discussed at RSA Conference 2010 within the Cloud Security Alliance Summit. The question still remains how to achieve this goal however. CVN is a very good start, but as we discussed on the podcast is missing some key elements.

HyTrust has announced Series B Financing in the amount of $10.5 Million with participation from Cisco, Granite Ventures as well as existing investors Trident Capital and Epic Ventures. This is very good news for HyTrust. While the Series B Funding was not much of a surprise given that HyTrust fits into the Virtualizaiton Security within its own niche. What is surprising is that Cisco is one of the backers of this innovative product.

Rethinking vNetwork Security

Brad Hedlund of Cisco asked the question, should the physical network security policy be different than the virtual network security policy? The answer is obviously no, but why are they treated separately? I and other have pushed the concept that to gain performance, redundancy, and security that you should use multiple network links to your virtualization host to separate traffic. However, does this really give you security?
