Service-Oriented Architecture (SOA) facilitates development of Business-to-Business (B2B) applications, by composing suitable services, either statically during design-time or dynamically at run-time. Dynamic reconfiguration in the service-oriented approach, involves replacing the statically composed services with some other ones, during run-time, only when it is necessary. This necessity might arise due to the need to accommodate change in user requirements, sudden unavailability of services or to keep up the non-functional requirements agreed in the Service Level Agreement (SLA). Dynamic composition is another approach, where each service is selected and composed at run-time. This approach provides more flexibility in selecting appropriate services during run-time as opposed to the static composition. However, there is a possibility of an additional overhead, compared to dynamic reconfiguration. This paper discusses an approach for SLA aware dynamic reconfiguration, that happens for the same instance of execution and it has also been captured as a pattern named I- RAILS. The various ways of dynamically reconfiguring the services has been illustrated with a case study application namely the Safe Building Security system. This approach of dynamic reconfiguration of the services is compared with the dynamic service composition.
