Getting Starting with Virtualization Security

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. Continue reading Getting Starting with Virtualization Security

Application Virtualization or Application Deployment, which one is better? (Part IV)

The ‘desktop’ is changing. The desktop is becoming a portal for users to access services they choose to complete their tasks, rather than providing a way to be given a fixed range of pre-determined applications. This portal is no-longer accessed from the top of a desk. The re-branded presence of externally hosted services as “cloud computing”, is and will have an impact on how organisations access and use software.

Virtual CPU’s, CPU Ready and Applications Performance on vSphere

In general you cannot infer the performance of an application running in a VM from looking at the resource utilization profile of that application or of the VM itself. There are many reasons for this documented in the Performance and Capacity Management White Paper available on this site. Continue reading Virtual CPU’s, CPU Ready and Applications Performance on vSphere

Desktone 3.0 the $1 virtual desktop

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. Continue reading Desktone 3.0 the $1 virtual desktop

PCI DSS: Virtualization Ready?

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?

OpenStack on Hyper-V – Microsoft does Public Cloud Interoperability

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.
