Abstract:
Infrastructure-as-a-Service cloud reduces the investment cost of using computing resources when compared with the complicated and expensive traditional business applications. Software-as-a-Service providers, who rent the
infrastructure resources to run their applications and serve their customers, are influenced by a variety of characteristics and
capabilities of the available resources. As a result, the decision made by business service owners to lease and use certain
cloud resources is an important one in order to achieve the planned outcome i.e. service value.
In this paper, we use a value based approach to develop a new model for measuring the benefits of providing computing
services in cloud. Based on our approach, customer satisfaction is modeled not only based on the response time offered by the
application provider, but also based on the allotted budget. The profit of the service owner is determined according to the
revenue generated by serving the customer. Using our model, the application owner is able to direct and control the decision
of renting cloud resources as per the current strategy. This strategy is led by a set of defined key performance indicators. In
addition, we present a scheduling algorithm that can bid for different types of virtual machines to achieve the target value.
We conduct extensive simulations using different types of Amazon EC2 instances with dynamic prices. The results show how
the model presents an effective tool for the application owners to control, quantify and reach the needed value of their
services per customer request.
