ENTROPY BASED METHOD TO CALCULATE WEIGHT FOR MULTI-CRITERIAN VM ALLOCATION POLICY IN COMPUTE CLOUD

Cloud computing is an attractive IT infrastructures for managing automatic optimum resource management as well as modern service delivery models. This paper will apply Entropy Weight method and TOPSIS power and SLA method to find the physical machine. This policy computes the scores of all the PMs that are capable for hosting a VM and selects the PM with the highest score. VM allocation based on the multicriteria is an efficient way for the optimal allocation weightage to each criteria will define priority to that parameter. Random weight will not justify the priority to the different parameter and entropy weighted method to generate the weightage based on the criterian considered for allocation. This method namely entropy weighted TOPSIS power and SLA Allocation policy that optimize energy consumption, number of VM migration and SLA violation.
