InterCloud: Utility-Oriented Federation of Cloud Computing Environments for Scaling of Application Services
Rajkumar Buyya, Rajiv Ranjan, Rodrigo N. Calheiros

TL;DR
This paper proposes InterCloud, a federation of cloud environments that enables dynamic, scalable, and cost-effective application service provisioning across multiple cloud providers to improve QoS and handle workload variability.
Contribution
It introduces the InterCloud architecture for utility-oriented federation of cloud environments supporting dynamic scaling and load distribution across multiple vendors.
Findings
Federated Cloud model improves response time.
Significant cost savings observed.
Enhanced QoS under variable workloads.
Abstract
Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world. However, existing systems do not support mechanisms and policies for dynamically coordinating load distribution among different Cloud-based data centers in order to determine optimal location for hosting application services to achieve reasonable QoS levels. Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination must happen automatically, and distribution of services must change in response to changes in the load. To counter this problem, we advocate creation of federated Cloud computing environment (InterCloud) that facilitates just-in-time, opportunistic, and scalable provisioning of application services,…
