Evaluation of Architecture of Component Based System

Being widely used in industries and organizations, Component based engineering is a technology for systems, highly successful in providing a product with high quality of functionality at low cost. This paper can enlighten beginners to the field of component based system and evaluating its architecture on certain parameters. Component based engineering can help to see how accurate, reliable or secure a system can respond, commonly named as system's non-functional properties. In this paper, the approach to evaluate the architecture of component based system is based on non-functional property, 'Performance'. Performance attribute ensures for the smooth and efficient operation of the software system. Next the architecture is evaluated at an early level of design which can be useful in a way, whether the architecture can meet the desired performance specifications or not thus saving cost. We analyzed the results over standard performance parameters namely response time, throughput and resource utilization. Logically, First the system over component based architecture is proposed, here SDLC (System development life cycle), next we model the architecture for performance over performance model. Here, MPFQN (Multichain PFQN) performance model for Iterative SDLC which work on component based system is used. The system was observed over some assumptions and scheduling disciplines given to various architectural elements. Varying the scheduling disciplines in the model gave varying results on performance parameters, that are observed using SHARPE Tool. The work studied in this paper was built on assumptions and simulations which can be extended to put in some real case study for some organization system.
