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, Chelmsford MA based Desktone Inc. today announced two major steps forward on the road to ubiquitous public cloud-based virtual desktops – The release of Desktone 3.0, and its partnership with Rackspace Hosting to provide public cloud-based virtual desktops for just $1 per day.

The PCI Security Standards Council published its latest PCI guidance in the form of PCI DSS 2.0, but quickly followed up with the document Navigating the PCI DSS v2.0. The Navigating document is very important to those who have virtual systems as it contains the basic guidance about virtualization while PCI DSS 2.0 does not provide anything specifically geared towards virtualization. However, there is an adjunct document that does layout PCIs thoughts on virtualization. This is stated within the Navigating the PCI DSS (v2.0) document.
The section on Virtualization is quite thin and have in effect four bullets to aid auditors and everyone else in where PCI is going with virtualization guidance. Continue reading PCI DSS: Virtualization Ready?
On October 22nd, Microsoft announced that it has partnered with Cloud.com to provide integration and support of Windows Server 2008 R2 Hyper-V to the OpenStack project. The announcement caused a great deal of interest here at the Virtualization Practice, as it signals an unexpected willingness on Microsoft’s part to pursue interoperability at the IaaS layer, allowing users to break out of the Hyper-v stack, whilst still retaining Hyper-v at the bottom. The fact this announcement came from Microsoft (not Cloud.com, Rackspace or OpenStack) seems to signal the seriousness of the intent.
In practical terms this means that Cloud.com puts a Hypervisor Abstraction Layer into the bottom of the OpenStack compute platform (Nova), and binds Hyper-V into that, to allow images to be deployed to and controlled on Hyper-V from OpenStack, using tooling that speaks one or other of the two OpenStack APIs (Native or Amazon EC2). Technically it is not a major step because although the initial version of Nova targeted libvirt and thereby Xen, KVM and Qemu, Citrix had already succceeded in providing a hypervisor abstraction layer in OpenStack for XenServer.

Wyse Technology has announced a new computing platform designed to capitalize on the growing market for cloud hosted virtual desktop environments that has the potential to un-jam one of the most emotive roadblocks towards the widespread adoption of desktop virtualization. Announced at Microsoft’s Tech Ed conference in Berlin, the Wyse Cloud PC presents an intriguing twist in the junction between desktop virtualization and thin client technologies that gets right to the heart of many IT professionals opposition to desktop virtualization.
There are few real differences between the new Cloud PC models and Wyse’s current range of thin and zero clients devices. It takes some close inspection of the hardware specification for each model to be able to identify a Wyse Cloud PC from a more conventional Wyse thin client. However there is one very significant difference; each Cloud PC ships with a Windows 7 license. The inclusion of a full Windows 7 license gives customers the option to take out a Software Assurance agreement for their Cloud PCs; this grants the customer the right to access a server hosted virtual desktop without the need to purchase additional Microsoft Windows Virtual Desktop Access (VDA) licenses. Continue reading Wyse explores the boundaries of cloud computing with new Cloud PCs
rPath has announced that they have added automated model based deployment for Windows applications to their existing capabilities for Linux based applications. Before we go into rPath and this announcement in some more detail, let’s look at the environments that rPath is addressing and now they are changing:
- Most enterprises have large numbers of business critical applications (for most companies the number is over 100)
- A significant portion of these applications are custom developed by the enterprise, and subject to continued feature enhancement and maintenance Continue reading rPath Addresses Automated Applications Deployment Across Physical, Virtual and Cloud Envionments
What is the point in virtualizing your Citrix XenApp Server? Consider that the goal of server virtualization is two fold – to make best use of idle computing resource; and to provide standardization and automation so to reduce the time to build and deliver new servers, or recover and restore broken ones. Is that a desirable and achievable goal for a Presentation Virtualization (PV) server such as Citrix XenApp? Of course: but its likely done already. Why add another expensive layer of software?
PV’s benefit is its capacity for high user density, and ease of management. With a PV server, users share the operating system environment, but each have their own independent session. A PV server could support 50%-100% more sessions that a hosted desktop solution, can that be improved an underlying virtualization layer?
PV servers, such as Citrix XenApp, are often cited as being ‘unvirtualizable’. They typically run with high utilization (sometimes too high) of CPU and memory resources, possibly even disk. As PV farms often need to support a high number of users, core server builds tend to be standardized, and application deployment to those servers automated. If you’ve already a standardized and automated environment, if you’ve already high hardware utilization – why go to the bother and cost of adding in a service that essentially does the same thing?
What could virtualization of your Citrix XenApp environment possibly do for you?
