Method and device for scheduling resources

An apparatus for scheduling resources, the apparatus comprising:

• a traversing module that traverses a user instance distribution of user instances of a user on one or more hosts in a cluster;
• a user detection module that detects whether a trigger condition for user scheduling of adjustment of the user instance distribution is satisfied;
• a user determination module that determines one or more first hosts from which one or more user instances are to be migrated out in response to determining the trigger condition for user scheduling is satisfied, each of the one or more first hosts comprising at least one user instance to be migrated out;
• and
• a user migration module that migrates the one or more user instances from the one or more first hosts to one or more second hosts to which the one or more user instances are to be migrated in.

One or more memories stored thereon computer-executable instructions that, when executed by one or more processors, cause the processor to perform acts comprising:

• traversing a user instance distribution of user instances of a user on one or more hosts in a cluster;
• detecting whether a trigger condition for user scheduling of adjustment of the user instance distribution is satisfied;
• determining one or more first hosts from which one or more user instances are to be migrated out in response to determining that the trigger condition for user scheduling is satisfied, each of the one or more first hosts comprising at least one user instance to be migrated out;
• and
• migrating the one or more user instances from the one or more first hosts to one or more second hosts to which the one or more user instances are to be migrated in.
