Architectural Styles for Adaptable Self-Healing Dependable Systems

Of all the possible architectural approaches to improving the dependability of software-based systems, only systems designed to be self-healing are able to adapt themselves at runtime in response to changing environmental or operational circumstances. In this paper, we discuss the basic functional requirements for self-healing systems, and explore a number of major issues related to architectur...

mRUBiS: An Exemplar for Model-Based Architectural Self-Healing and Self-Optimization

Self-adaptive software systems are often structured into an adaptation engine that manages an adaptable software by operating on a runtime model that represents the architecture of the software (model-based architectural self-adaptation). Despite the popularity of such approaches, existing exemplars provide application programming interfaces but no runtime model to develop adaptation engines. C...

Architectural Synthesis: Integrating Multiple Architectural Perspectives

There are many tools and techniques available to understand and analyze a system at the architectural level. Each of these may provide its own perspective of the key architectural elements of the system. We introduce the process of architectural synthesis to deal with the problem of integrating these different architectural perspectives. We emphasize the utility of the synthesis process in supp...

Distilling Software Architectural Primitives from Architectural Styles

Architectural styles codify commonly used idioms in system structures, organizations, and interactions. Existing classifications of architectural styles provide empirical guidelines for style selection, but fail to systematically characterize styles or reveal their foundations. Moreover, the mapping between architectural styles and their implementations is generally poorly understood. This pape...
