The main goal of Cloud Computing is to provide services of high level quality, such as hosting and data processing, focusing on minimizing the costs. With this, companies specialized in this subject are responsible for handling the required resources. However, the steady growth in demand by society has provided a high consumption of these features offered by the service provider (energy, hardware, etc.). Thus, new rules are being taken in the way to use only the computation requested by the user, and some of these focus on shutdown of servers not used for a certain period of time. However, this solution, while ensuring effective energy savings provides an increase in costs related to repairing machines, caused by the constant change of state of a single server. Therefore, this project proposes to maintain the energy savings obtained by such solutions, improving the scheduling of applications on computers that will be connected, putting into standby or hibernation.
