As business critical applications move into production virtualized environments, the need arises to ensure their performance from a response time perspective. Legacy Applications Performance Management tools are in many cases not well suited to make the jump from static physical systems, to dynamic virtual and cloud based systems. For these reasons enterprises need to consider new tools from vendors that have virtualization aware and cloud aware features in their APM solutions. Vendors like AppDynamics, BlueStripe, dynatrace, New Relic, OPNET, Optier, Quest, and VMware (AppSpeed) are currently leading this race to redefine the market for APM solutions.

There is great outrage to Microsoft’s reluctance to play ball and support virtualization of IE. Without an alternative, the solutions offered by Microsoft are expensive, cumbersome and difficult to maintain. Virtualising the application may well allow different browser versions to co-exist – but the user-experience can be cumbersome with links to other applications not always launching the correct browser and users having to know which browser to choose. Unibrows offers an interesting alternative utilising isolation to support the deployment of different controls and centralisation to allow management and control and importantly wrapped up in what sounds like a very appealing cost.

vCloud Director is a good start at an IT as a Service platform for enterprises looking for a VMware specific solution that does not integrate with existing physical or non-VMware provisioning mechanisms. Enterprises looking for IT as a Service solutions that span multiple virtualization platforms and that span provisioning across virtual and physical resources should look at alternatives from Platform Computing DynamicOps, newScale, Embotics, Euclyptus, ManageIQ and rPath as these vendors all offer heterogeneous enterprise class IT as a Service platforms.
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.
In my last post I talked about how to resolve an issue where a disgruntled employee walked out with the USB memory stick that had VMware ESXi installed on it. In that particular case, the VMware ESXi host kept on running and I was able to get a backup and restore the current running configuration via some PowerShell Magic. All in all it was a pretty easy issue to resolve with very little down time. This got me thinking about which method would be the best option to use in the Enterprise. Installing to local disks or installing to a USB memory stick.
One week after Austin, TX-based Virtual Bridges Inc. announced that IBM is using its flagship VERDE solution to provide virtual desktop management and provisioning capabilities for the IBM Cloud Service Provider Platform, and just days after Desktone Inc. launched release 3.0 of its desktop cloud management service; Virtual Bridges is back in the news again with its announcement today of VERDE 5.
The Virtualization Security Podcast on 11/2 was quite a change from our normal podcast. Instead of featuring a vendor as a guest panelist, Gurusimran S Khalsa (known as GS) joined us. Our topic was getting started with virtualization security with a real world twist.

Application Deployment solutions reduce the cost of delivering applications and help you manage license use? With the end of support for Windows XP happening in 2014 many businesses are moving towards Windows 7 – ideally this inevitable cost is kept low. Application Virtualization can be used on ‘traditional’ desktops and laptops. Application Virtualization can be used in client side-hypervisors. Application Virtualization extends and increases the efficiencies of desktop virtualization as well as enabling portability and improving compatibility of applications. Application Virtualization can free you, not only from the limitation of having to “install within each device”, but lead the way in offering an alternative to “install on only corporate devices”. Application Virtualization can be a tool to reduce the complexity and time needed to move from Windows XP to Windows 7, and from future application updates. Indeed, for many companies, Application Virutalization is an option that can be used now by utilising existing license agreements, or for less cost than converting the application to run as a web-based service.

In a virtual system the tenancy to translate over-provisioning physical CPU’s into over-provisioning virtual CPU’s can be very harmful as the graph above shows. Assigning four vCPU’s to a VM makes it harder for that VM to get scheduled in as the hypervisor has to wait for four vCPU’s to become available at the same time. It is therefore the case that configuring a smaller number of vCPU’s for an application can actually improve the amount of CPU resource that it actually gets and therefore improve its performance. Investing in tools (like VMTurbo) that do this work for you automatically can help you convince applications owners of this, and thereby help their applications perform better.
