ABSTRACT
Event-driven architecture (EDAs) improves scalability by combining stateless servers and asynchronous interactions. Models to predict the performance of pure EDA systems are relatively easy to make, systems with a combination of event-driven components and legacy components with blocking service requests (synchronous interactions) require special treatment. Layered queueing was developed for such systems, and this work describes a method for combining event-driven behaviour and synchronous behaviour in a layered queueing model. The performance constraints created by the legacy components can be explored to guide decisions regarding converting them, or reconfiguring them, when the system is scaled.

Performance of CORBA-Based Client-Server Architectures
Middleware has been introduced to provide interoperability as well as transparent location of servers in heterogeneous client-server environments. Although such benefits accrue from the use of middleware, careful consideration of system architecture is ...
Empirically-grounded reference architectures: a proposal
QoSA-ISARCS '11: Proceedings of the joint ACM SIGSOFT conference -- QoSA and ACM SIGSOFT symposium -- ISARCS on Quality of software architectures -- QoSA and architecting critical systems -- ISARCSA reference architecture describes core elements of the software architecture for systems that stem from the same domain. A reference architecture ensures interoperability of systems through standardization. It also facilitates the instantiation of new ...
Towards pattern-based architectures for event processing systems
Recently, event processing EP has gained considerable attention as an individual discipline in computer science. From a software engineering perspective, EP systems still lack the maturity of well-established software architectures. For the development ...
