QoS-Driven Dynamic Reconfiguration of the SOA Based Software

SOA based software is typically based on dynamic reconfiguration, since it is the composition of services. But few works focus on the non-functional reconfiguration of the SOA-based software. This paper presents an approach for QoS driven dynamic reconfiguration of the SOA based Software. The approach can reconfigure a SOA based software to comply with a new QoS constrains by replacing its individual or multiple component services. The individual component services are replaced according to the descending order relative to the critical factors. While if the attempts fail, multiple component services will be replaced together. In our case study, an example is given to show the approach is efficient to reconfigure a SOA based software to meet a new QoS constraints.
