Abstract

Embodiments of the present disclosure relate to a method, device and computer program product for managing a service. The method comprises in response to processor credits for the service reaching threshold credits at a first time instant (t1), determining a second time instant when a first operation for the service is to be performed. The method further comprises determining, based on a set of historical processor credits between the first time instant and the second time instant, first processor credits related to a second set of time periods which is between the first time instant and second time instant. The method further comprises determining, based on a first time length from the first time instant to the second time instant, a second time length of the first set of time periods and a third time length of the second set of time periods, second processor credits that can be obtained between a third time instant when the second set of time periods ends and the second time instant; in response to the first, second and third processor credits satisfying a predetermined condition, performing the second operation within the second set of time periods. The method may increase the time for performing the second operation without affecting the first operation.
