“…The main tasks accomplished by DCDM are: process of publishing of CLA templates (consumer and provider); C3-aware deployment of applications (described in Section 3.1); mapping of DSLs to CLAs (as described in Section 4.1); brokering between consumer and provider by matching requested and provided CLAs, i.e., CLA-CLA matching; Business Process Management (BPM); and data fragmentation and execution (as described in Section 4.2). For publishing of CLAs we consider advanced approaches beyond typical SLA repositories, as for example such approach presented in [18], in order to facilitate liquid Cloud markets. CLA-CLA matching considers matching of providers and consumers in terms of requested and provided level of security, trust, and privacy.…”

Abstract-Cloud computing represents a promising computing paradigm, where computational power is provided similar to utilities like water, electricity or gas. While most of the Cloud providers can guarantee some measurable non-functional performance metrics e.g., service availability or throughput, there is lack of adequate mechanisms for guaranteeing certifiable and auditable security, trust, and privacy of the applications and the data they process. This lack represents an obstacle for moving most business relevant applications into the Cloud. In this paper we devise a novel approach for compliance management in Clouds, which we termed Compliant Cloud Computing (C3). On one hand, we propose novel languages for specifying compliance requirements concerning security, privacy, and trust by leveraging domain specific languages and compliance level agreements. On the other hand, we propose the C3 middleware responsible for the deployment of certifiable and auditable applications, for provider selection in compliance with the user requirements, and for enactment and enforcement of compliance level agreements. We underpin our approach with a use case discussing various techniques necessary for achieving security, privacy, and trust in Clouds as for example data fragmentation among different protection domains or among different geographical regions.

“…One approach that deals with this problem is the SLA mapping technique. SLA mappings are documents used to bridge the differences between two differing SLAs [12], [13], [3], [14]. Unlike ontologies, SLA mappings are dynamic and allow users to keep their SLAs that may already be used in other processes [3].…”

However, due to the lack of semantic description of SLA elements, mappings must be manually defined by market participants, thus keeping the high cost of the service selection process.…”

Abstract-Cloud computing is a novel computing paradigm that offers data, software, and hardware services in a manner similar to traditional utilities such as water, electricity, and telephony. Usually, in Cloud and Grid computing, contracts between traders are established using Service Level Agreements (SLAs), which include objectives of service usage. However, due to the rapidly growing number of service offerings and the lack of a standard for their specification, manual service selection is a costly task, preventing the successful implementation of ubiquitous computing on demand. In order to counteract these issues, automatic methods for matching SLAs are necessary. In this paper, we introduce a method for finding semantically equal SLA elements from differing SLAs by utilizing several machine learning algorithms. Moreover, we utilize this method to enable automatic selection of optimal service offerings for Cloud and Grid users. Finally, we introduce a framework for automatic SLA management, present a simulation-based evaluation, and demonstrate several significant benefits of our approach for Cloud and Grid users.

Abstract-Dynamic and self-adaptable markets are fundamental for the successful implementation of the Cloud computing paradigm where computing resources are provided on demand and dynamically to the heterogeneous user base. Usually, in Cloud markets, contracts between traders are established using Service Level Agreements (SLAs), which include objectives of service usage. However, Cloud markets face challenges, which are usually not evident in other market types, such as non-standardized goods and large variety of resource types offered on the market, resulting in low number of matches of consumers' bids and providers' asks. Moreover, existing Cloud market mechanisms are usually static and cannot react on dynamic change of user requirements. To counteract these problems, we propose an adaptive approach for autonomically deriving public SLA templates (i.e., templates for generation of electronic contracts) based on user requirements. Although this approach brings many benefits, it also incurs cost to users, since they must adapt specifications of their requirements in order to match automatically generated public SLA templates. In this paper, we reduce this cost by autonomically modifying specifications of user requirements. We introduce a method for adapting public SLA templates not only in respect to definitions of SLA attributes, but also to attribute values. Based on an appropriate utility and cost model, we evaluate the approach and show that it significantly improves the performance of the adaptive SLA template technique.
