In “IT as a Service Reference Architecture“, we presented a a categorization of the the functionality and the products that are needed in order to construct an IT as a Service system. Purposely missing from this architecture was the question of how to monitor the performance of the services delivered from the service catalog via the underlying policies and automation in the IT as a Service stack.

In the first Virtualization Security Podcast of 2011, we had Brad Hedlund with us once again. Not to talk about the Cisco Virtualization Security Gateway (VSG), but about the security of what I call physical-virtual devices that provide network virtualization within the hardware. Or what Brad Called Network Interface Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere. Continue reading Cisco Pushing More vNetwork into Hardware
Mainstream virtual desktop solutions have focused their efforts on providing the best platform for hosting virtual desktop environments. Hypervisors, image management, and connection brokers are the top feature sets that companies have looked at during their comparisons. Moving up the stack, these vendors are now focusing on user personalization management, but do not have what is considered to be a full desktop management solution. So are our end-to-end virtual desktop solutions really complete? Continue reading Desktop Lifecycle Managment and what Novell has to offer
I am nearing completion of my ‘dig-out’ from the recent Nor’easter that blew through New England, dumping quite a bit of snow. When you dig out of a snow storm, you start with paths to the garage or car, paths to the utilities, and in some cases paths to the wood pile and other out buildings. Sooner or later that perfect landscape of white is marred by new mounds of snow and clear-cut paths through it to the various locations on the property. When you look at these paths and the snow is high enough, they look like tunnels. The large tunnels (driveway) meet smaller and smaller ones. The perfect landscape of snow is now marred. This is just how a firewall looks when you put holes in it to let through various services. The more services, the more tunnels and paths will be cut. When speaking about the cloud or virtual environments, the increase in paths and entry points becomes a serious issue. Continue reading Digging out after a Snowstorm: Similar to our virtual environments?
On January 12 2011, NetApp announced that it is going to acquire Akorri. The significance of this can only be understood by first going through some background on Akorri.
Akorri was founded in 2005 by Rich Corley, a serial entrepreneur. Rich has a very deep background in storage and in particular in how storage performance impacts the performance of workloads that rely upon storage systems. At the time of the founding virtualization was not the overwhelming phenomena that it is today and the focus of Akorri was upon understanding how the intersection of storage performance and the performance of the rest of the infrastructure (servers and networks) impacted the performance of the overall system. Continue reading NetApp to Acquire Akorri
Ericom has has won the race to deliver the first new product release of the “Year of Desktop Virtualization” with the launch of Ericom PowerTerm WebConnect 5.7.
WebConnect (sorry Ericom, but “PowerTerm WebConnect 5.7” takes too much space on the page to type out every time) is Ericom’s answer to Citrix XenApp and XenDesktop, plus or minus a few bells and whistles. On the plus side WebConnect includes mainframe and midrange terminal emulation software to provide access to legacy systems, as well as offering support for mixed environments consisting of servers running Windows Server 2003, 2008, 2008 R2 grouped together in a single farm, and manages to do all this with a single product where Citrix still requires two.
