To provide a solution for the complexity of active monitoring load balancing algorithms to distribute the workload efficiently on the available virtual machines by ensuring that overutilization of resources or virtual machines will not occur in the cloud system. This book shows a step by step procedure and detailed description of the various load balancing algorithms for virtual machine along with the measures to increase the performance of active monitoring load balancing algorithms. Finally, the proposed work is compared with the existing algorithms. This Research work could allow giving concepts to users about active monitoring load balancing algorithm with better processing time, response time, cost-effectiveness and delivery of other services. It also gives novel vision to concerned customer towards better and modernized concept in cloud computing environment. Moreover, this study could be used as a reference point for further research to incorporate additional features. Apart from this, Network Science research lab is conducting research on various advanced technologies like Li-Fi, Software Defined Network, Data Center Network etc apart from this research.
