Cloud computing is a network of computing resources that are delivered to various customers as a service over internet. Resources are available dynamically to the users; however, management of resources in a dynamic fashion stands a vast area for researchers. Resource provisioning is the process of determining, how available computing resources are allocated among various user's request in such a way that, it has to reduce the overall response time and cost. Various customers want to run different kinds of applications on the cloud server. Each customer may have different quality of service (QoS) requirements based on their workload. This makes resource provisioning a complex task. To simplify this task resource provisioning model is needed, which will enhance cloud system usability and dependability as well as quality of service. In this paper, we proposed a hybrid cuckoo search algorithm for scheduling resources to data centres in multi-cloud environment by minimising the overall response time for various user's requests.
