ExtraHop has now made an important contribution to the question of how to measure applications performance across physical and virtual environments. Properly deployed ExtraHop can play a critical role in helping enterprises virtualize the 60% of the remaining applications that are “hard”, “performance critical”, and “business critical”. As vSphere 5.0 is right around the corner, the timing could not be better.

What is still missing here is any kind of an end-to-end view of infrastructure latency that is also real time, deterministic and comprehensive. The marrying of the SAN point of view with the IP network point of view is the obvious combination. The hard issue here will be the identification of the applications so that these view of infrastructure performance can be surfaced on a per application basis. In summary, we have a long way to go here, and this just might be why so many of those virtualization projects for business critical and performance critical applications are having so much trouble getting traction.

News: VMTurbo Raises the Bar for Free vSphere Monitoring – Again

VMTurbo’s unique Service Assurance capabilities (and the ability to charge for them in the paid products) allows VMTurbo to make baseline performance and capacity management for vSphere environments available for free. This represents a significant redefinition of where the value is and where the value is not in the virtualization performance management business.

Applications Performance Profiling is an essential step in the process of virtualizing business critical and performance critical applications. In this case “performance” means response time not resource utilization. The virtualization team should go even further and commit to meeting response time based SLA’s for business and performance critical virtualized applications.

The Dell VIS stack (Advanced Infrastructure Manager, Self-Service Creator and Director) now represents the most functionally rich virtualization management offering on the market, as it is sourced from best of breed IT as a Service vendor DynamicOPS and best of breed self learning analytics vendor Netuitive. This stack backed up by Dell’s ability to sell into its customer base with whom Dell is already heavily interacting on the subject of virtualization puts Dell and it partners in a compelling position.

RUM (also called End User Experience Management) is becoming a critical feature of modern APM solutions. This is being driven by the emergence of rich client platforms like Ajax, Adobe Flash, Adobe Flex, and Microsoft Silverlight as well as the emergence of the iPad and Android based tablets as platforms for client side business applications. These applications development trends when combined with virtualization, IT as a Service and Cloud Computing will make RUM into a critical capability for being able to assess how the end user is doing irrespective of what is happening to the deployment model of the back end application.

VMware’s “Squeeze the OS” Strategy – Open War with Microsoft and Red Hat

The announcement of CloudFoundry means the public declaration of full on war between VMware, and the two traditional OS vendors, Microsoft and Red Hat. Both traditional (not quite legacy yet) OS vendors are going to have to rapidly bolster their own PaaS cloud offerings. This will be a particular challenge for Microsoft as Microsoft has always gravitated strongly towards having a tightly integrated stack of software, and not being very open to open source frameworks like Spring, Ruby, and PHP.
