The term "green computing" refers to the use of computers and the resources connected with them in an eco-friendly and ecologically responsible manner. This use is related to the information technology industry and services. The practice of using the least number of resources possible is another component of green cloud computing. For the purpose of controlling the waste of resources, a distributed service system that includes a job dispatcher and a physical server's virtual machine modules for generating queueing models, enforcing ISN policies, and modelling SN policies are all put to good use. It is well known that virtual machines are installed on physical machines and the number of hosts is reduced through the use of methods like virtualization, consolidation, and migration as well as metrics and methods for green cloud and algorithm strategies. There has been much research on this subject..
