  Service Oriented Architecture is a loosely coupled architecture designed to
tackle the problem of Business Infrastructure alignment to meet the needs of an
organization. A SOA based platform enables the enterprises to develop
applications in the form of independent services. To provide scalable service
interactions, there is a need to maintain services performance and have a good
sizing guideline of the underlying software platform. Sizing aids in finding
the optimum resources required to configure and implement a system that would
satisfy the requirements of Business Process Integration being planned. A web
based Sizing Tool prototype is developed using Java Application Programming
Interfaces to automate the process of sizing the applications deployed on SOA
platform that not only scales the performance of the system but also predicts
its business growth in the future.
