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 (t), 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.

Method, device and computer program product for service management

Embodiments of the present disclosure provide a method, device and computer program product for migrating data. The method comprises initiating a first migration job for a first client and a second migration job for a second client. The method also comprises setting a first cache file for the first client and a second cache file for the second client, and a cache file records a hash value of a migrated file of a client. Moreover, the method further comprises executing the first migration job and the second migration job in parallel, wherein the first migration job is executed using the first cache file and the second migration job is executed using the second cache file.
