Cloud Computing is an emerging technology in which desktop services are delivered online on network.Consumers pay for the service how much they use such as water, electricity telephone or gas.Service consumer does not need to invest capital amount on infrastructure and IT experts. Revenue is the main focus of any business. In Cloud Computing revenue depends on proper VMs utilization and SLA.Cloud infrastructure provider have their own resources or they hire some resources to meet the customers requirements. Hiring other infrastructure, cost too much and performance depends on other hired systems which lead towards SLA violation. SLA violation in Cloud business minimizes the revenue of the Cloud provider. This paper discusses the IaaS model with SLA to maximize the Infrastructure provider revenue. Two types of SLAs are implemented in this model. One SLA is between service consumer and provider and second SLA is between hired external resources and IaaS provider. We propose such polices and algorithm which increase the company own infrastructure utilization, minimize the response time and SLA violation to enrich the revenue. This algorithm and policies will reduce the infrastructure cost and minimize the SLA violation. It will handle the dynamic changes in the customer request and will allot resources with dynamic pricing according to their dynamic requests.
