Is virtualizing Citrix XenApp a waste of time and effort? In spite of the hardware abstraction allowing easier image management and OS upgrades; in spite of options for higher availability and faster recovery, even fail-over; in spite of enabling silo consolidation; in spite of enabling managing user capacity on servers – especially for x32 environments, but also x64; … what could virtualization of your Presentation Virtualization environment possibly do for you?
I was invited to CSI 2010 this year to speak on the Low Hanging Fruit of Virtualizaiton Security. This presentation brought to light some simple to implement features that would give you the most security for what I consider very little cost or effort. These 7 items if implemented will improve the overall security of your virtual environment.
I got a call from a client today that is running a VMware ESXi server as a proof of concept in their SMB environment. The admin that setup the VMware ESXi Server configured the ESXi server to boot and run ESXi from a USB memory stick. Things have been running fine but the company and the administrator that setup the server had a falling out, so to speak, and the administrator left the company and took the USB memory stick with him. The server continues to run fine as ESXi basically runs from memory but, rebooting this host is now not an option since there are no files available for the host to boot from. So what is the best way to recover and get things back to normal? I did a little research and the information that I have found will work will both ESXi 3.x as well as vSphere ESXi.

newScale, rPath and Eucalyptus have partnered to provide an elastic infrastructure (Eucalyptus), automated software deployment and management (rPath), and a service catalog (newScale). This provides an interesting alternative to the monolithic stack offered by VMware with vSphere and vCloud Director.
The Freemium sales model is a business model innovation best suited to inexpensive products that are very easily understood (and therefore not very new or very different) and that solve an obvious problem in a manner that is more convenient for the customer to acquire and implement. There are not many new virtualization and cloud technology companies who set out to produce undifferentiated products which suggests that a general application of the Freemium model to startups in our ecosystem is ill advised. Enterprise customers should pay great attention to products that are being marketing in this manner to ensure that they do not end up growing the use of something that was purchased in a tactical manner into a strategic use case.
Last week, there were several major virtualization security announcements, that taken singularly may only apply to the specific products, but taken together show the growth of the virtualization security ecosystem.
New Relic announced that it now support four application types, Ruby-on-Rails, Java, .Net and PHP. New Relic has therefore broken new ground in the question of trade-offs between depth of monitoring into an application, and breadth of platform support. The prior generation of byte code instrumentation vendors never supported more than two platforms – J2EE and .Net. Products that monitor the OS still cannot see into an application the way that New Relic can – and now New Relic brings this depth of insight to more platforms than anyone else has ever address.
When I first got started in virtualization it was a very new technology and during that time there were not that many resources available to the virtualization administrator and sometimes it would have been nice to be able to see what others were doing and to be able to share my thoughts and ideas with others to make sure I was presenting the best possible solution to my customers. During these early years the VMTN Community Forum was established and these forums were the place to do this collaboration. I found this to be one of the best arenas to ask questions and share ideas. The VMTN Community area quickly took off and in a lot of cases was the quickest way to find an answer, solution to your problem or issue you were trying to resolve.
Desktop Virtualization is not an easy undertaking. There – I’ve said it. “But,” you may say, “I take a copy of the desktops I have, I run them on servers in the data-centre. Once that’s done, I don’t need to update those desktop devices; I can update the virtualized workspace instead far more quickly. The desktops are running on server hardware so they will be more reliable. Eventually, someone may well offer to host these workspaces on some infrastructure out in The Cloud”.
“Really, how hard can it be?”
