An Enhanced Scheduling in Weighted Round Robin for the Cloud Infrastructure Services

Infrastructure as services (IaaS) in Cloud computing offers the features of increasing the hardware resources (CPU cores, RAM, hard disk or storage space, and network bandwidth) on-demand in no time or utilizing the additional configured VMs to execute the business applications in a shortest time as possible by utilizing the dynamic scaling. The scheduling algorithm in the IaaS allows the applications to respond in a shortest response time by utilizing the configured resources very efficiently and it can have a greater impact in performance of the IaaS Cloud Environment by reducing the load balancing actions. This work introduces an enhanced scheduling in Weighted Round Robin algorithm for the cloud infrastructure based on the heterogeneous resources and heterogeneous with interdependent jobs combined with its unpredicted arrivals and the varied instruction length of the requested jobs.
