Technology growth is exponential. We all know about Moore’s Law by which the density of transistors on a chip doubles every two years; but there is also Watts Humphrey’s comment that the size of software doubles every two years, Nielsen’s Law by which Internet bandwidth available to users doubles every two years, and many others concerning storage, computing speed, and power consumption in a data center. IT organizations and especially IT operations must cope with this afflux of technology, which brings more and more services to the business, as well as the management of the legacy services and technology. I believe that the two most important roadblocks that prevent IT from optimizing its costs are in fact diversity and complexity. Cloud computing, whether SaaS or IaaS, is going to add diversity and complexity, as is virtualization in its current form. This is illustrated by the following chart, which compiles answers to the question: “Approximately how many physical servers with the following processor types does your firm operate that you know about?”
If virtualization could potentially address the number of servers in each category, it does not address the diversity of servers, nor does it address the complexity of services running on these diverse technologies.
The marriage of Gomez and Compuware is starting to bear fruits. One of the key aspects of web application performance management is end user experience. This is approached largely from the data center standpoint, within the firewall. But the best solution to understand the real customer experience is to have an agent sitting on the customer side of the application, without the firewall, a possibility that is clearly out of bounds for most public facing applications. The Gomez-Compuware alliance is the first time that these two sides are brought together within the same management application, Compuware Vantage. What Vantage brings to the equation is the Application Performance Management (APM) view of IT Operations: response time collected from the network and correlated with infrastructure and application monitoring in the data center. But, it’s not the customer view. What Gomez brings with its recent version, the “Gomez Winter 2010 Platform Release” is a number of features that let IT understand what goes beyond the firewall: not only how the application content was delivered, but how the additional content from external providers was delivered and what was the actual performance at the end user level: the outside-in view of the application is now combined with the inside-out view of IT Operations provided by Vantage APM. And this is now spreading outside the pure desktop/laptop user group to reach out the increasing mobile and smart phone crowd. IT used to be able to answer the question of “is it the application or the infrastructure?” with Vantage. IT can now answer a broader set of questions: “is it the application, the internet service provider, the web services providers?’ for an increasingly broader range of use-case scenarios.
