Priority Based Load Balancing for Intercloud Computing Environments

Adoption of cloud computing based computing solutions is growing day by day in nearly all sectors of society. Technological advancements such as load balancing help service providers uphold the quality of service, and thereby retain the confidence of service consumers. Collaborations among cloud environments can be established for resolving load balancing and fault tolerance issues up to a certain extent. However, the gigantic increase in consumption of cloud services makes cloud resource management difficult in intercloud environments too. Load balancing helps resolve workload balancing problems for collaborated cloud platforms. We present an enhanced and priority-oriented mechanism for sharing resources for workload balancing in collaborated cloud environments. In order to provide enhanced load balancing solution, the suggested resource sharing mechanism works on the priority values of participating instances. Employment of the suggested load balancing mechanism avoids starvation by means of lowering waiting time. The suggested technique has been implemented on a physical cloud testbed built using OpenStack cloud computing setup on CentOS Linux operating system. The experimental results reveal lesser waiting time of the highly loaded cloud instances.
