It is important that applications can directly monitor fine-grained scaling performance (such as consistency-related replication delays and query-specific response time) and specify application-specific policies for autonomic management of the scaling. However, there is no general mechanism and reusable framework and infrastructures to help this. The current facilities in cloud-hosted relational databases are also very limited in providing fine-grained and consumer-centric monitoring data. The situation is exacerbated by the complexity of the different underlying cloud technologies and the need to separate scaling policy from business logic. This paper presents an architecture framework to facilitate a consumer-centric, application-managed autonomic scaling of relational databases in cloud. The architecture framework includes a new consumer-centric monitoring infrastructure and customisable components for sensing, monitoring, analysing and actuation according to application-level scaling policies without modifying an existing application. We evaluated our framework using a modified Web 2.0 application benchmark. The results demonstrate the framework's ability to provide application-level flexibility in achieving improved throughput, data freshness (different levels of consistency) and monetary saving.","PeriodicalId":116686,"journal":{"name":"Proceedings of the WICSA/ECSA 2012 Companion Volume","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132009528","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}

However, setting up cloud environments for performance testing still requires a significant amount of manual effort. To aid performance engineers in this task, we developed a framework that integrates several common benchmarking and monitoring tools. The framework helps performance engineers to test applications under various configurations and loads. Furthermore, the framework supports dynamic server allocation based on incoming load using a response-time-aware heuristics. We validated the framework by deploying and stress-testing the MediaWiki application. An experimental evaluation was conducted aimed at comparing the response-time-aware heuristics against Amazon Auto-Scale.","PeriodicalId":116686,"journal":{"name":"Proceedings of the WICSA/ECSA 2012 Companion Volume","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115680521","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}

Identification of migration strategies and practices for service engineering is critical for successful legacy migration, and SOA adoption in industrial setting. This paper presents the results of an interview survey on the migration strategies in industry. The purpose of this paper is twofold: 1) to discover the migration strategies that industrial practice adopts 2) to identify the benefits of making such strategies explicit. Results of the survey have been analyzed in terms of migration activities and the available knowledge assets. As a result, we generalize the practice of industrial migration into a Lean & Mean SOA migration strategy. In addition, the uses of the strategy pinpoint promising industry-relevant research directions.","PeriodicalId":116686,"journal":{"name":"Proceedings of the WICSA/ECSA 2012 Companion Volume","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127351993","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}

Companies and other cloud users are expecting to receive significant benefits from the new cloud based technologies. To what extent these benefits materialize for enterprise IT is not clearly understood. In this paper, we examine the perceived benefits of cloud computing from the cloud users' perspectives. Cloud users include users of SaaS/PaaS/IaaS, ranging from end-users, to service developers and system administrators. Using content analysis techniques, we examine one of the major discussion forums of cloud computing. Rather than offering a yes/no answer to the question posed, we offer five empirically drawn insights on the perceived benefits of cloud computing. It is proposed that the empirical insights gained are valuable to both researchers and practitioners. The value lies in a more holistic view on the promised benefits' landscape.","PeriodicalId":116686,"journal":{"name":"Proceedings of the WICSA/ECSA 2012 Companion Volume","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126569237","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}

Architecture change log data represents a source of evolution-centric information in terms of intent, scope and operationalisation to accommodate changing requirements in existing architecture. We investigate change logs in order to analyse operational representation of architecture change instances to discover an implicit evolution-centric knowledge that have been aggregating over time. Change instances from the log are formalised as a typed attributed graph with its node and edge attribution capturing change representation on architecture elements. We exploit graph matching as a knowledge discovery technique in order to i) analyse change operationalisation and its dependencies for ii) discovering re-current change sequences in the log.
