The aim of CLAM is to monitor the different layers of an SBA and correlate the monitoring results, such that in the event that a problem occurs an effective adaptation strategy is inferred for enacting a coordinated adaptation across all layers of the SBA. An important aspect of CLAM is the definition of the appropriate Service-Level Agreements (SLAs) for third party services utilised in the different layers of the SBAs. In this paper, we present insights into how to define SLAs for CLAM, by analysing SBAs in order to differentiate the third party business, software and infrastructure services utilised by the SBA. As a case study, we apply the analytical approach to an existing platform-as-a-service framework, which has been developed as an SBA and could benefit from CLAM. The analysis reveals the different third party services and their characteristics, as a precursor to defining SLAs. The case study successfully demonstrates how distinct SLAs for business, software and infrastructure services may be applied respectively in the BPM, SCC and SI layers of an SBA, to provide a flexible monitoring and adaptation response across layers.","PeriodicalId":357051,"journal":{"name":"QASBA '11","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116307114","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 in most cases the adaptation is not trivial due to the following facts. First, SBA has a complex layered system where the application is implemented through a composition of services, which in turn are provided by platforms and run on top of infrastructures. Second, as a result of this multi-level application system there exist several adaptation approaches isolated from each other, which focus on a specific concern of one level ignoring the overall impact of the adaptation on the whole service-based system. To tackle this problem we propose a cross-layer adaptation manager (CLAM) whose contribution is two-fold: (i) It provides a platform that integrates and coordinates existing analysis and adaptation tools, which target specific system concerns, to assess the impact of an adaptation at the different levels. (ii) Covering the whole system for the SBA, it provides an analysis algorithm that incrementally constructs consistent adaptation strategies starting from an initial adaptation trigger originated at any level. The paper introduces the proposed approach and presents its first implementation with concrete analysis and adaptation tools.","PeriodicalId":357051,"journal":{"name":"QASBA '11","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129692907","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}
