In this paper we enumerate the properties to be guaranteed by so-called liquid service-oriented architectures and define a set of design constraints that make up a novel architectural style for liquid architectures. These constraints drive the careful construction of a pattern, the Restful Actor (Reactor), which enables to deliver the required scalability by means of replication of its constituent parts. Reactors feature a Restful Web service interface and a composable architecture which is capable of delivering scalability and high performance in a way that is independent from the chosen deployment infrastructure. We discuss how the Reactor can be deployed to run on distributed (shared-nothing) execution environments typical of virtualized Cloud computing environments as well as on modern multicore processors with shared memory architectures.","PeriodicalId":234615,"journal":{"name":"2011 Ninth Working IEEE/IFIP Conference on Software Architecture","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124941477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, there is a growing need for new methods to evaluate the dependability of architectures interfacing with such environments. This paper presents a method for evaluating the security quality attribute of architectures in service-based systems. The proposed method combines some properties of the Architectural Tradeoff Analysis Method (ATAM) and security testing using Implied Scenario. In particular, the scenario elicitation process of ATAM is improved by utilising Implied Scenario technique to generate scenarios which may be undetected using plain ATAM. An industrial case study of a problem related to securing data at the Software-as-a-Service layer on Force.com Cloud platform is adopted to validate the new method. The results indicate that our method found four additional security scenarios beyond the plain ATAM, resulting in four new risks and two new tradeoff points.","PeriodicalId":234615,"journal":{"name":"2011 Ninth Working IEEE/IFIP Conference on Software Architecture","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124023600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A system's analyzability, in particular, is influenced by its decomposition into components. But into how many components should a system be decomposed to achieve optimal analyzability? And how should the elements of the system be distributed over those components? In this paper, we set out to find answers to these questions with the support of a large repository of industrial and open source software systems. Based on our findings, we designed a metric which we call Component Balance. In a case study we show that the metric provides pertinent results in various evaluation scenarios. In addition, we report on an empirical study that demonstrates that the metric is strongly correlated with ratings for analyzability as given by experts.","PeriodicalId":234615,"journal":{"name":"2011 Ninth Working IEEE/IFIP Conference on Software Architecture","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128753154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a departure from traditional AKM, instead of a focus on decisions, the focus shifts to decision making. Additional decision theories and decision-making philosophies are needed to supplement the ubiquitous normative decision theory and its associated rational decision-making, which is assumed by AKM to-date as the de facto decision theory. Extensions to the agent model paradigm have been explored to portray the evolution of a set of architecture decisions according to multiple decision theories sourced from the human sciences of neurology, psychology, and sociology. Model Of Software System Architecture Decision-making (MOSSAD) uses agent-based modeling and simulation in an attempt to understand the dynamic complexity of interdependencies & interactions found in decision-to-decision relationships amongst hundreds of decisions and their asynchronous evolutions over time. If understanding is possible, this should lead to knowledge for legitimate progress of architectural decision-making. This in turn should lead to a new theory about the time period necessary for architectural design on a project.","PeriodicalId":234615,"journal":{"name":"2011 Ninth Working IEEE/IFIP Conference on Software Architecture","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115605150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our focus of evolution is on the concrete tasks integrators have to perform to update deployed SPL products, in particular products that require runtime updates with minimal interruption. The complexity of updating a deployed SPL product is caused by multiple interdependent concerns, including variability, traceability, versioning, availability, and correctness. Existing approaches typically focus on particular concerns while making abstraction of others, thus offering only partial solutions. An integrated approach that takes into account the different stakeholder concerns is lacking. In this paper, we present an architectural approach for updating SPL products that supports multiple concerns. The approach comprises of two complementary parts: (1) an update viewpoint that defines the conventions for constructing and using architecture views to deal with multiple update concerns, and (2) a supporting framework that provides an extensible infrastructure supporting integrators of a SPL. We evaluated the approach for an industrial SPL for logistic systems providing empirical evidence for its benefits and recommendations.","PeriodicalId":234615,"journal":{"name":"2011 Ninth Working IEEE/IFIP Conference on Software Architecture","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122052596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A chunk allows related information to be retrieved collectively as a unit and simplifies information location tasks. We propose a new semi-automated approach based on the actual usage of ADs by previous users, i.e. by capturing users' exploration paths through ADs while engaging in information seeking tasks and making these paths available for future retracing and analysis. As part of our work, we developed KaitoroCap, a document navigation capture and visualisation tool. Its main features are exploration paths capture, retrieval, analysis, hierarchical tree-view visualization of paths, path searching, section rating, tagging, commenting, expanding/collapsing and page model generation to enable dynamic restructuring of ADs.
