Security issues of cloud computing environments are considered a major challenge for its full adoption. A Service Level Agreement (SLA) corroborates the shared management vision provided by the cloud computing paradigm, which can assist with related security issues. The necessity to address security requirements in cloud computing SLAs is considered important for both providers and consumers, along...
With the evolution of service computing ecosystems and the promises of the Cloud, there is an increasing need for service evaluation and monitoring across a wide range of QoS dimensions. Although in the literature service monitoring is tightly coupled with Service Level Agreement establishment, existing approaches do not provide a holistic model for Cloud service evaluation. In this paper, we present...
Cloud Accounting refers to how cloud usage is recorded and charged. Even in the case of a single cloud provider this task is hard and there is a context which it becomes even worse, known as federated cloud. It happens when a cloud provider dynamically outsources resources to other providers in response to demand variation. In this context, we identified some research addressing this area which developed...
This paper describes a specification language and architecture for managing distributed software and mapped compute, storage and network infrastructure services dynamically, beyond the state of the art in cloud computing. This is referred to as dynamic application topology orchestration, where the mapping and configuration of distributed, interconnected, interdependent application services and infrastructure...
