Dynamic Software Architectures
Dynamic Software Architectures A Style-Based Modeling and Refinement Technique with Graph Transformations DISSERTATION in Computer Science submitted to the Faculty of Computer Science, Electrical Engineering, and Mathematics University of Paderborn by Sebastian Th¨one in partial fulfillment of the requirements for the degree of doctor rerum naturalium (Dr. rer. nat.) Paderborn, October 2005 ii Abstract A good architectural design allows to capture the overall complexity of large, distributed systems at a higher level of abstraction. This is especially im- portant for reconfigurable systems where the architectural configuration is subject to (constant) changes at runtime. When designing such a dynamic architecture, the software architect has to bring the functional business re- quirements and the available communication and reconfiguration mechanisms of the intended target platform in line. As it is a complex task to incorporate these often diverging requirements into the architectural model, we propose a stepwise approach similar to the MDA initiative. We start with a platform-independent model capturing the business requirements and add platform-specific details in a later step. For each level of platform abstraction and associated platform, we define an ar- chitectural style which describes the characteristics of the platform. This way, conformance to the architectural style entails consistency between model and the underlying platform. Besides run-time configurations of components and connections, archi- tectural models also comprise the description of processes that control the communication and reconfiguration behavior. To provide operational seman- tics, we formalize architectural models as graphs and architectural styles as graph transformation systems. UML is added as high-level modeling language on top, and profiles are used to adapt UML to certain architectural styles. -

Just Enough Software Architect
Praise for Just Enough Software Architecture: A Risk-Driven Approach If you’re going to read only one book on software architecture, start with this one. Just Enough Software Architecture covers the essential concepts of software architecture that everyone — programmers, developers, testers, architects, and managers — needs to know, and it provides pragmatic advice that can be put into practice within hours of reading. —Michael Keeling, professional software engineer This book reflects the author’s rare mix of deep knowledge of software architecture concepts and extensive industry experience as a developer. If you’re an architect, you will want the developers in your organization to read this book. If you’re a developer, do read it. The book is about architecture in real (not ideal) software projects. It describes a context that you’ll recognize and then it shows you how to improve your design practice in that context. —Paulo Merson, practicing software architect and Visiting Scientist at the Software Engineering Institute Fairbanks’ focus on “just enough” architecture should appeal to any developers try- ing to work out how to make the architecting process tractable. This focus is made accessible through detailed examples and advice that illustrate how an understand- ing of risk can be used to manage architecture development and scope. At the same time, Fairbanks provides detail on the more academic aspects of software architec- ture, which should help developers who are interested in understanding the broader theory and practice to apply these concepts to their projects. —Dr. Bradley Schmerl, Senior Systems Scientist, School of Computer Science, Carnegie Mellon University The Risk-Driven Model approach described in George Fairbanks’ Just Enough Software Architecture has been applied to the eXtensible Information Modeler (XIM) project here at the NASA Johnson Space Center (JSC) with much success. -

On the Responsibilities of Software Architects and Software Engineers
On the Responsibilities of Software Architects and Software Engineers in an Agile Environment: Who Should Do What? Antony Tang Ton Gerrits, Peter Nacken Hans van Vliet VU University Océ Technologies VU University Amsterdam the Netherlands Amsterdam the Netherlands [ton.gerrits,peter.nacken]@oce.com the Netherlands [email protected] [email protected] ABSTRACT not easily defined. Architecture frameworks and standards such as As there is considerable freedom for software workers to decide TOGAF [2] and ISO/IEC 42010 [3] only provide general what to do in an agile environment, there is a need to be explicit guidelines. It is up to individual organizations and their architects about social aspects such as task ownership between roles and the to interpret those guidelines to define work practices and agility in owning those tasks. We have conducted interviews and a responsibilities, so architects’ responsibilities are subject to survey at a large organization to explore these issues. The results interpretation and individual preferences. indicate that there are areas where architects and software When an architect adjusts his/her responsibilities to suit the engineers have different views on task ownership. Some of the project situation, their responsibilities may not be made explicit to less exciting tasks such as documentation and issue clarification the software development team. Furthermore, in an agile then easily become a hot potato nobody wants. environment software architects and developers often have overlapping responsibilities, the division of responsibilities Categories and Subject Descriptors cannot be sharply defined. For instance, both roles may do D.2.1[ Requirements / Specifications ], D.2.2 [ Design Tools and analysis, design, documenting, coding and even testing. -
