In the design and analysis of fault-tolerant systems, fault models have served us well to describe the theoretical limits. But with the inclusion of malicious acts, the direct application of fault models has exposed limited applicability. However, we can take advantage of the powerful fault models if we defer their direct application from the events that lead to faults, that is, the fault causes, and instead focus on the effects. This way one can avoid questions referring to the meaning of fault models in the context of previously unsuitable faults like Trojan horses or Denial of Service (DoS) attacks. Instead, we can use fault models at the level of abstraction where the application maps on the infrastructure. In this paper fault models are discussed in the context of system survivability and malicious act. It is shown that these models can be used to balance the demands put on the application and the capabilities of the underlying infrastructure. Active and imposed fault descriptions are defined that allow to match the mechanisms that provide survivability to the application with the infrastructure-imposed limitations. By defining a system as a collection of functionalities, individual functionalities and their associated fault descriptions can be analyzed in isolation.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126394438","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}

Assessment and determination of impact of the nonfunctional aspects such as service granularity, governance, composition, and orchestration is an overarching concern and this exercise should be carried out at the architecture design stage rather than post implementation and deployment. In this paper we illustrate, by means of a simple example, the use of Colored Petri Nets (CPNs) to model service composition and orchestration. We use the associated software tool called CPN Tools to perform the analysis. The results can be used in many ways such as to determine design alternative or to check conformance with existing service level agreements, etc. Colored Petri Nets, being a graphical modeling language suitable for modeling distributed, concurrent, deterministic and nondeterministic systems with synchronous and asynchronous communications, offer a natural choice for this endeavor. Although the example is given in the context of web services, CPNs view of interaction and coordination of systems is abstract and can be applied to different notions of services equally well.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131761487","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}
