1. A computer-implemented method for prediction of required number of server computing systems for future computing workload, the computer-implemented method comprising the steps of: connecting, by one or more processors, a portion of a plurality of server computing systems of a data center, wherein the connected plurality of server computing systems are connected within a network; determining, by the one or more processors, at least one class S server computing system of the plurality of server computing systems, wherein the at least one class S server computing system is configured to deploy an application of the plurality of server computing systems, wherein the application already installed but it not have been started and serve users; determining, by the one or more processors, at least one class I server computing system of the plurality of server computing systems, wherein the at least one class I server is configured to deploy an application of the plurality of server computing systems, wherein the application actually run and serve users using functions of the application; determining, by the one or more processors, at least one class R server computing system of the plurality of server computing systems, wherein the at least one class R server is disconnected from the network but remain in the data center; and computing, by the one or more processors, at least one server computing system of each of the class I server computing system, class S server computing system, and class R server computing system based on a deployment rate, an undeployment rate, and a removing rate, wherein the deployment rate indicates at least one class S server computing system of the class S server computing systems that is transferred from the class S server computing systems to the class I server computing systems within a predefined time period, wherein the undeployment rate indicates at least one class I server computing system of the class I server computing systems that is transferred from the class I server computing systems to the class S server computing systems within a predefined time period, and wherein the removing rate indicates at least one class I server computing system of the class I server computing systems that is transferred from the class I server computing system to the class R server computing system in a predefined time period.
