Abstract: Cloud computing is another form of internet. In cloud computing the online services are conducted to be pay-as-you-use. The Service Level Agreements (SLA) are agreements signed between user and service provider. In this paper, we mainly focus on Multi-level SLAs and Dynamic Negotiations. In the Multi-level SLAs each user is specified with an SLA by service provider and the Dynamic Negotiation is occurred when we need to specify the exact constraint for the user’s service request. Also, in this paper we designed a model for Data as a service for remote sensing data from that model. We used weighted sum model (WSM) to decide which provider finally provides best requirement made by the user.
