Resource scheduling in cloud is a challenging job and thescheduling of appropriate resources to cloud workloads depends on the constraintsand QOS requirements of cloud applications. In cloud environment, user’sworkload with different constraints and the heterogenity of resouces encountersproblems for allocation of resources, which cannot be solved efficientlyexisting resource allocation policies..
Existing algorithms focus on only one ortwo constraints., This paper presents a resource scheduling strategy thatmaximizes the resource utilization aswell as meet the client request with minimum expenditure by consideringdifferent constarints like cost,trust and priority. ie, it combines the existing three resource scheduling algorithmbased on selected constraints and effectively schedule the jobs as per therequest.

Cloud Computing is ancomputing technology that is rapidly consolidating itself as the next step inthe development and deployment of increasing number of distributed application.
Cloud computing is nothing but a specific style of computing where everythingfrom computing power to infrastructure, business apps are provided as aservice. It’s a computing service rather than a product. In cloud, sharedresources, software and information is provided as s metered service over thenetwork. When the end user accesses some service is cloud, he is not aware ofwhere that service is coming from or what is platform being used or where it isbeing stored. The cloud computing paradigm makes the resource as a single pointof access to the number of clients and is implemented as pay per use basis.Though there are number of advantages of cloud computing such as virtualizedenvironment, equipped with dynamic infrastructure, pay per consume, totallyfree of software and hardware installations, prescribed infrastructure and themajor concern is the order in which the requests are satisfied which evolvesthe scheduling of the resources. Allocation of resources has been made effi-ciently that maximizes the system utilization and overall performance. Cloudcomputing is mainly sold or rented on demand on the basis of time constrainsbasically specified in hours or minutes.
So the scheduling has to be done insuch a way that the resource utilization has need done efficiently. In cloudcomputing environment, resource allocation or load balancing takes place at twolevels. First, when an application is uploaded to the cloud, the load balancerassigns the requested process to physical computers, attempting to balance thecomputational load of multiple applications across physical computers. Second,when an application receives multiple incoming requests, these requests shouldbe each assigned to a specific requested application instance to balance thecomputational load across a set of instances of the same requested application.
