Safe consolidation and migration

A computerized apparatus having a processor, the processor being adapted to perform the steps of:

• receiving a target host and an application to be migrated to a target host;
• estimating a target load of the application to be migrated;
• generating a synthetic application which simulates a simulated load, the simulated load being smaller than the target load;
• loading the synthetic application to the target host;
• monitoring behavior of the target host, the synthetic application, or a second application executed thereon;
• subject to the behavior being satisfactory:
• if the simulated load is smaller than the target load, then repeating said generating, said loading and said monitoring, wherein said loading is repeated with increased load;
• and
• otherwise migrating the application to the target.

A computer program product comprising a computer readable storage medium retaining program instructions, which program instructions when read by a processor, cause the processor to perform a method comprising:

• receiving a target host and an application to be migrated to a target host;
• estimating a target load of the application to be migrated;
• generating a synthetic application which simulates a simulated load, the simulated load being smaller than the target load;
• loading the synthetic application to the target host;
• monitoring behavior of the target host, the synthetic application, or a second application executed thereon;
• subject to the behavior being satisfactory:
• if the simulated load is smaller than the target load, then repeating said generating, said loading and said monitoring, wherein said loading is repeated with increased load;
• and
• otherwise migrating the application to the target.
