Due to a gradual decrease in the cost of purchasing new computers, there is more and more computing devices entering the market. The large quantity of new devices creates heterogeneity among them and this complicates the administration of computing environments, because is necessary to keep the systems running in compatibility with quite different devices simultaneously. The WSE-OS system proposes a solution for centralizing data and resources that addresses this problem effectively. Using wireless networking technology, the WSE-OS tool uses a Thin Client structure that allows its clients to execute instantiations of virtualized operating systems stored on the server. This paper presents a proposal that changes WSE-OS's structure including the ability to run with multiple servers, having as its goal increase scalability, availability and reliability through server’s data replication and staggering of connections. Data replication consists in detecting changes on data from a given server and transmit it to the others prioritizing the consistency among replicas. The staggering of connections works on actively distributing the clients among servers to improve system’s performance
