A method and system for resource management is provided. The method includes generating a physical server pool. Resources of the physical server pool and additional resources of additional physical server are monitored and monitored data is retrieved during the monitoring. A utilization rate of the additional physical server pools is determined to be less than a threshold value. In response a group of physical servers is migrated to a free server pool. The physical server pool is determined to need an additional server and each physical server pool is rated based on a calculated chance for required usage. A first physical server is allocated to the physical server pool.
