Cloud computing is a service-oriented architecture. Cloud offers different service models such as Software as a Service(SaaS), Infrastructure as a Service(IaaS) and Platform as a service(PaaS). The core component of every cloud is resource provisioning. Resources such as CPU, memory, and storage are provisioned dynamically to support cloud applications. This paper addresses scheduling of the tasks dynamically by taking into account the total execution or completion time of the tasks and resource utilization. The Cloud scheduler queries the Cloud Information System to check for the availability of resources, knowing their properties, and then scheduling the resources as per task requirements. The results are sent back to users once the task completes. The challenge lies in scheduling the tasks in a heterogeneous environment.
