Towards Cooperative Cloud Service Brokerage for SLA-driven Selection of Cloud Services

Enterprises are showing growing interest in outsourced cloud service offerings that can help them increase business agility and reduce operational costs. Cloud services are built to permit easy, scalable access to resources and services, and are entirely managed by cloud services' providers. However, enterprises are faced with the inevitability of selecting suitable cloud services that can meet their functional and quality requirements. We propose, in this paper, a federation of Cloud Brokers (CBs) for cloud services' selection. Cloud brokers of the federation cooperate to assist service consumers select suitable cloud services, which can offer their required service and fulfill their quality-of-service (QoS) requirements. Service selection is part of our integrated framework for SLA management, service provisioning, and SLA compliance monitoring.
