In Applications Performance Equals Response Time, not Resource Utilization, we took the position that while for the majority of the applications deployed on physical hardware the general practice was to infer their performance by looking at normal vs. abnormal resource utilization statistics, once you virtualize an application, it becomes necessary to directly measure its response time in order to ensure adequate service to business constituents and end users.

Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.
For a developer, and subsequently the team of people that has to support certain kinds of applications in production, a PaaS cloud can be a wonderful thing. Why can a PaaS cloud be so wonderful? Because if you have a web based application based upon Java, Ruby-on-Rails, or .NET you can find a cloud provider that handles the entire hardware and software platform for your application.
It is now very clear the VMware vSphere 4.0 and 4.1 have demonstrated the robustness and performance necessary in order for them to be trusted virtualization platforms for many business critical applications. It is also very clear that many organizations are well down the road toward putting business critical applications on vSphere. We may not yet be at the point where the most response time critical applications (like online trading) are on vSphere, but we are certainly at the point where line of business applications like SAP and enterprise resident CRM applications are being virtualized.
2010 will be the year that many enterprises confront two very important changes to how they will use server virtualization. The first change is that as VMware vSphere has proven its maturity, performance and scalability enterprises will increasingly put business critical tier applications, at least in part on virtualized platforms. The second change is that at the same time, these very same enterprises will start to evaluate virtualization platforms from other vendors, in particular Hyper-V from Microsoft.
Vizioncore was one of the early entrants in the business of monitoring resources for VMware back when the company was independent and the name of the product was esxCharter. Quest Software subsequently acquired Vizioncore, and since the acquisition has focused upon taking components of it Foglight infrastructure and application monitoring suite and targeted them at the VMware market through the vFoglight product which is marketed by VizionCore. Since Vizioncore has the extremely rich set of enterprise infrastructure and application monitoring assets to pull from, Vizioncore is well positioned to deliver a very capable solution focused upon monitoring availability, resource utilization and capacity for the virtualization market.
