Cloud computing has recently emerged in the landscape of Information Technology as a compelling paradigm for managing and delivering services over the Internet in a performance- and cost-effective way. However, its development is still at its infancy, with many issues worthy to be investigated. In this chapter, we analyze the problem of service level provisioning and the possible strategies that can be used to tackle it at the various layers of the cloud architecture, focusing on the perspective of cloud-based application providers. We also propose an approach for the dynamic QoS provisioning of cloud-based applications which takes into account that the provider has to fulfill the service level settled with the application users while minimizing the resources outsourced from the cloud infrastructure in such a way to maximize its profits.

Abstract
Cloud computing has recently emerged in the landscape of Information Technology as a compelling paradigm for managing and delivering services over the Internet in a performance- and cost-effective way. However, its development is still at its infancy, with many issues worthy to be investigated. In this chapter, we analyze the problem of service level provisioning and the possible strategies that can be used to tackle it at the various layers of the cloud architecture, focusing on the perspective of cloud-based application providers. We also propose an approach for the dynamic QoS provisioning of cloud-based applications which takes into account that the provider has to fulfill the service level settled with the application users while minimizing the resources outsourced from the cloud infrastructure in such a way to maximize its profits.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
