Generating a scaling plan for external systems during cloud tenant onboarding/offboarding

A computer program product comprising:

• a computer readable storage medium having computer readable program code stored on the computer readable storage medium, the computer readable program code being executed by a central processing unit (CPU) of a computer system to cause the computer system to perform a method comprising:
• the computer system receiving plans for onboarding first one or more tenants of a cloud computing environment and offboarding second one or more tenants of the cloud computing environment;
• the computer system receiving historical data about behavior of tenants of the cloud computing environment;
• based on the received plans for the onboarding and the offboarding and based on the historical data, the computer system generating a scaling plan for scaling computer resources of external systems during the onboarding and the offboarding, the scaling plan specifying a timeline indicating dates and times at which changes in workloads associated with the external systems are required for the onboarding and the offboarding;
• based on the scaling plan, the computer system determining that a scaling is needed for one or more computer resources of an external system included in the external systems;
• and
• in response to the determining that the scaling is needed, the computer system triggering the scaling for the one or more computer resources of the external system at a date and a time indicated by the timeline.

A computer system comprising:

• a central processing unit (CPU);
• a memory coupled to the CPU;
• and
• a computer readable storage medium coupled to the CPU, the computer readable storage medium containing instructions that are executed by the CPU via the memory to implement a method comprising:
• the computer system receiving plans for onboarding first one or more tenants of a cloud computing environment and offboarding second one or more tenants of the cloud computing environment;
• the computer system receiving historical data about behavior of tenants of the cloud computing environment;
• based on the received plans for the onboarding and the offboarding and based on the historical data, the computer system generating a scaling plan for scaling computer resources of external systems during the onboarding and the offboarding, the scaling plan specifying a timeline indicating dates and times at which changes in workloads associated with the external systems are required for the onboarding and the offboarding;
• based on the scaling plan, the computer system determining that a scaling is needed for one or more computer resources of an external system included in the external systems;
• and
• in response to the determining that the scaling is needed, the computer system triggering the scaling for the one or more computer resources of the external system at a date and a time indicated by the timeline.
