A Profit Oriented Session-based Admission Control Mechanism for the Cloud Environment

Abstract

The proliferation of cloud-computing services has encouraged business-owners to migrate their applications to the cloud. With the existence of the Service Level Agreement (SLA) in the cloud, the business-owners can guarantee the quality of service they were promised to get from the providers. However, in such shared environment, there is a high probability of overload situations to occur violating the SLA, and causing profit losses to both providers and clients. This paper proposes an SLA-aware Profit-Oriented session-based Admission Control (POAC) mechanism that manages the overload problem in three-tier Web-based applications hosted on a cloud environment. The proposed Admission Control (AC) was validated using simulation. Our experiments show that the proposed approach makes profit-aware decisions, while taking the SLA in consideration. Thus benefiting both the service providers and the business-owners.
