In an attempt to reduce costs by taking advantage of efficient computing resources, new technologies and architectures developed are gaining wide acceptance in the market. One such technology is cloud computing, which tries to solve problems like energy consumption and allocation of space in data centers or large companies. The cloud is an environment shared by multiple clients and enables elastic growth, where new features such as hardware or software, can be hired or sold at any time. In this model, customers pay for the resources they use and not for all the architecture involved. Therefore, it is important to determine how efficiently those resources are distributed in the cloud. Therefore, this study aimed to develop a scheduling algorithm for cloud efficiently determine the distribution of resources within the architecture. To achieve this goal, experiments were conducted with managers of open-source cloud, detecting the deficiency of current algorithms. This algorithm was compared with the algorithm of the OpenStack Essex manager, a manager of open-source cloud. The experimental results show that the new algorithm could determine the machines less the cloud overloaded, achieving thereby distribute the processing load within the private environment
