The Virtual Desktop Design Maxim: Start With User Requirements

A good Virtual Desktop Design architect needs to ask, “what is the best solution for this environment?”  To answer that question, an effective design considers – “does the solution meet the users’ needs?

If your virtual desktop design starts with sizing hardware to support the amount of current physical desktops, starts with considering what applications can be virtualised, it has likely started in the wrong place. Continue reading The Virtual Desktop Design Maxim: Start With User Requirements

Performance Monitoring for IT as a Service

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.

Cisco Pushing More vNetwork into Hardware

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

Desktop Lifecycle Managment and what Novell has to offer

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

Digging out after a Snowstorm: Similar to our virtual environments?

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.
