摘要：Cloud computing has recently emerged as one of the buzzwords in the IT industry. SaaS layer is the upper layer of the cloudcomputingmodel. It offers consistent access to software applications to the clients over the Internet without direct investment ininfrastructure and software. It is a service provided to client in terms of applications running on the cloud-computing infrastructure hostedby the service providers. The main work of this layer is to deliver the software application services over the internet with in the real timewhen users demand for it in pay per use manner. The main concern of this paper is on how to minimize the infrastructure cost andmaximize the SaaS provider profit for that two algorithms are proposed. The proposed algorithms are designed in such a way that works onthe mean value which efficiently uses the available VM Space to handle the client request instead of creating a new VM to deliver theservices. And by that the SAAS provider has not to pay the extra penalty cost and hence they get a profit to serve the request of clients withtheir satisfaction and without violation of SLA
