Performance prediction of COTS component-based Enterprise Applications

One of the major problems in building large-scale enterprise systems is anticipating the performance of the eventual solution before it has been built. This problem is especially germane to modern Internet-based e-business applications, where failure to provide high performance and scalability can lead to application and business failure. The fundamental software engineering problem is compounded by many factors, including application diversity, architectural trade-offs and options, COTS component integration requirements, and differences in performance of various software and hardware infrastructures. This paper investigates the feasibility of providing a novel and practical solution to this problem. The approach as demonstrated, constructs useful models that act as predictors of the performance for component-based systems hosted by middleware infrastructures such as CORBA, COM+ and J2EE. 1
