A survey on Cloudware and scheduling algorithm for Multi-Cloud

Nowadays, it is more appealing for users to schedule tasks in Multi-Cloud than in Single-Cloud. Using Multi-Cloud can help users to achieve better Quality of Service (QoS), reliability and flexibility. However the cloudwares and scheduling algorithms for Multi-Cloud are quite various. So the purpose of this paper is firstly to survey the broker architecture and all kinds of Cloudwares in Multi-Cloud and then review a variety of scheduling algorithms for optimal provisioning services and resources in Multi-Cloud.
