Solving Enterprise Applications Performance Puzzles
- Share to:
Poorly performing enterprise applications are the weakest links in a corporation ’ s management chains, causing delays and disruptions of critical business functions. In trying to strengthen the links, companies spend dearly on applications tuning and sizing; unfortunately, the only deliverables of many of such ventures are lost investment as well as the ruined credibility of computer professionals who carry out failed projects. In my opinion, the root of the problem is twofold. Firstly, the performance engineering discipline does not treat enterprise applications as a unified compound object that has to be tuned in its entirety; instead it targets separate components of enterprise applications (databases, software, networks, Web servers, application servers, hardware appli- ances, Java Virtual Machine, etc.). Secondly, the body of knowledge for performance engineering consists of disparate and isolated tips and recipes on bottleneck trouble- shooting and system sizing and is guided by intuitional and “ trial and error ” approaches. Not surprisingly, the professional community has categorized it as an art form — you can find a number of books that prominently place application performance trade in the category of “ a rt form,” based on their titles.
