A study on managing the performance and resources of a business process engine using nonlinear and switching control systems

This technical report presents the experiment results of the a case study conducted on a business process server applying the nonlinear and switching control system design approaches given in [1, 2]. Here, we introduce the business scenarios and objectives of the businesses process server before we go on to the details of the system architectures and experimental results. WSO2 BPS WSO2 is one of the leading open-source enterprise software platform providers, giving services to companies such as ebay. From their product suite, WSO2 Stratos business process server (BPS) is a multi-tenanted Platform as a Service (PaaS) middleware environ- ment, which provides out of the box support to deploy software workflows for multiple clients (or tenants) using a single instance. WSO2 BPS already provides data, security and execution isolation, however performance isolation is not looked at so far. In this work we combine and extend the WSO2 BPS to manage performance of multiple customers while sharing the resources e ff ectively. The details are provided in Section 2.
