Abstract

System, method and program product for determining if a plurality of applications executed on a plurality of servers can be executed on a single server. First program instructions determine if the single server has sufficient processor power to execute the plurality of applications. Second program instructions determine if the plurality of applications have a same type of operating system on the plurality of servers. Third program instructions determine if the plurality of applications have a same type of middleware on the plurality of servers. The first program instructions determine peak processor utilizations and times of the peak processor utilizations for the plurality of applications, respectively, to determine whether the single server has sufficient processor power to execute the plurality of applications. Other program instructions determine the single server to be a standard vendor server which has a smallest processor adequate to support processing requirements of the plurality of applications and has a predetermined, minimum processing power in reserve. Other program instructions determine if the plurality of applications have a similar function or are identical. Other program instructions determine if the plurality of applications have a same type of application environment on the plurality of servers.
