The Virtualization Practice

For a developer, and subsequently the team of people that has to support certain kinds of applications in production, a PaaS cloud can be a wonderful thing. Why can a PaaS cloud be so wonderful? Because if you have a web based application based upon Java, Ruby-on-Rails, or .NET you can find a cloud provider that handles the entire hardware and software platform for your application.

DesktopVirtualization

Can you use Desktop Virtualization in your organization to improve IT delivery? Desktop Virtualization, as a concept, is straightforward – separate the desktop environment from the physical machine. This gives you benefits in terms of speed of delivery, how you can provide access to mobile and remote workers, how you can ensure security and compliance.

Browsium crafts lifeline for IE 6 users

Startup Browsium, is readying a lifeline for enterprise IT organizations that moving to Windows 7 but unable to escape their addiction to Internet Explorer 6. The Washington DC-based startup staffed by ex-Microsoft employees is planning to release UniBrows an add-on for Internet Explorer 8 that lets customers access IE6 dependent web apps from the now defacto standard that is IE 8.

Red Hat today announced the acquisition of startup PaaS vendor, Makara, which provides a deployment platform for most of the Open Source application stacks onto most of the IaaS cloud infrastructures. Red Hat intends to use the purchased technology rather than the product itelf. It gains additional application-level management, monitoring and configuration functionality for an emerging stand-alone PaaS offering to drive its customers towards a fully RHEL-cloud.

I had a fun day resolving a licensing issue for a client. This one was a little different than I had seen in the past. The cluster is question is an eight node cluster running ESX 3.5. The error message that I received when trying to perform a vMotion was “Unable to migrate from HostA to HostB: Virtual machine has 2 virtual CPUs, but the host only supports 1. The number of virtual CPU’s may be limited by the guest OS selected for the virtual machine or by the licensing for the host.”

If you are a hyperscale (such as for the Cloud) data center manager, one of your top concerns is always how to get the maximum amount of computing work done per Watt of power consumed. With that in concern at the forefront Cloud Providers like Google, Microsoft, and Facebook have strong incentives to explore new solutions to delivering compute cycles. Rumors coming out of Facebook suggest that it is looking to move away from its current X86 architecture platform in favor of servers based on ARM Holdings Cortex processor range. Porting an entire service to a new processor platform may not appear to be a sensible direction to take but porting to a new architecture is more a financial consideration than a technical one. If the cost per unit of performance justifies it , it is cheaper to pay a few programmers to rework the apps for a new architecture than it is to buy more servers.

Many times we virtualization experts push for backups without the agents as these backups tend to be in our opinion, cleaner and faster. But what if you could get the benefits of your existing backup tools (such as Tivoli) but gain the power and advantages of using all the possibilities within the virtual environment. For VMware vSphere this is possible using the Pancetera backup tools.

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.
