A method, node and computer program for a resource controller node (100) for enabling automatic adaptation of the size of a pool of resource units, the resource units needed for operation of an application in a computer environment. The method comprises requesting a predicted capacity demand by a resource controller unit (110) from a prediction unit (120), retrieving a configuration for calculation of the predicted capacity demand from a workload characterization unit (130) by the prediction unit (120) as a response to the request, retrieving at least one key performance indicator based on workload metric data from a monitor unit (140) by the prediction unit (120) as a response to the request, calculating a capacity difference of compute units based on the at least one key performance indicator and the configuration by the prediction unit (120), the capacity difference defined by a difference of compute units between a current capacity allocation and a predicted capacity demand, translating the difference of compute units to a difference of resource units by a resource adapter unit (150), transmitting a size adaptation instruction comprising the difference of resource units to the pool of resource units, instructing the pool of resource units to adapt its size of the pool of resource units according to the difference of resource units, thereby enabling automatic adaptation of the pool of resource units to meet an actual workload and a predicted capacity demand of the application. |
