Design and Development of Improved Squirrel Search-based Secured VM Migration in the Cloud Sector with Optimal Key Management

Abstract

This article aims to design a new secured data transmission, VM migration, and placement. VM is constructed for hosting the applications by taking the essential resources, and OS is given by the user after receiving a request from the customer by the data center of the cloud. Here, the best fitness index-based Squirrel Search Algorithm (BFI-SSA) to minimize the number of active servers in the cloud. Further, the BFI-SSA is used for implementing the optimal VM migration with the help of a multiobjective function using the makespan and energy consumption. For migrated VM, the secured data transmission is performed by the same improved SSA with “data sanitization and restoration” with adaptive key management. This BFI-SSA algorithm is intended to generate the key and to increase the privacy of the migrated data. The energy consumption of the designed method attains 8% regarding the best rate value. Moreover, the designed method attains a minimum cost function to get a higher convergence rate in the 40th iteration. The given offered method attains a better makespan rate regarding best rate values. Thus, the simulation result has outperformed the suggested model and has achieved low energy and power consumption when compared to other-state-of-art methods.
