If synthetic transactions are dead as an approach for determining availability and performance from the perspective of the end users of an application then something has to take their place. The two candidates are approaches that analyse data on the IP network, and client side agents. Both will likely rise in prominence as more applications become more dynamic.

When considering a Virtual Desktop Design a good architect needs to ask “what is the best solution for this environment?” For many, once you’ve considered the needs of your users, it is a combination of desktop delivery models – some virtual, some physical. Ideally the user is unaware of which model is being delivered to them, they consume that service on an appropriate device, at an appropriate time. Ringcube perhaps first to market for this type of solution with their Workspace Virtualization Engine.
Monitoring the performance of the infrastructure, applications and services in IT as a Service environments will require that monitoring solutions become multi-tenant, can be instantiated by ITaaS management tools without any further configuration, and that they automatically “find” their back end management systems through whatever firewalls may be in place. These requirements will probably be the straw that breaks the camel’s back for the heavyweight complex legacy tools that were in place prior to to the onset of virtualization, the public cloud and now IT as a Service. ITaaS is the tipping point that should cause most enterprises ignore every monitoring tool that they have bought in the past and to start over with a clean sheet of paper.
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 ID Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere.
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?

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.
The acquisition of Akorri by NetApp demonstrates the importance of Infrastructure Performance Management solutions as virtualization progresses into the realm of business critical applications, and as public clouds hope to do the same. However rather than signaling a “game over” this acquisition really raises both the visibility and the importance of both the problems that Akorri solved, and the true end-to-end problems that remain.

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.
