Performance-Driven Software Architecture Refactoring

Performance engineering of software architecture can be defined as the process of analyzing the performance of a software architecture and then reacting to problems emerging from such analysis by refactoring the software architecture in order to meet performance requirements. In the last decade, many approaches in this field have appeared, whereas the problem of reacting to problems by proposing and evaluating alternative solutions through architectural refactoring has been much less treated. Indeed, the introduction of automated support to refactoring becomes crucial to drive architectural evolutions that might lead to performance improvement. This tutorial is aimed at introducing notations, methodologies and tools that can be adopted for Performance-Driven Software Architecture Refactoring.
