a data center coupled to the LEO satellite, the data center being configured to:

determine an activation window of an application;

map orbital movements of the LEO satellite to the activation window of the application;

allocate a resource group to the application; and

schedule a server in the data center to run the application according to a result of the mapping and the allocation of the resource group.

9 . The system of claim 8 , wherein the data center is configured to schedule the server to run the application prior to the LEO satellite arriving at an activation region of the application.

10 . The system of claim 8 , wherein the data center is configured to:

send an in-band message queue (PLMQ) based query to the application to retrieve permission policies of the application; and

identify an activation time window of the application from the permission policies.

11 . The system of claim 8 , wherein the data center is configured to:

retrieve physical parameters of the LEO satellite; and

determine orbital movements of the LEO satellite using the physical parameters.

12 . The system of claim 8 , wherein the resource group comprises at least a network resource, a compute resource, and a storage resource.

13 . The system of claim 8 , wherein the data center is configured to:

detect a change in a workload of the application;

allocate a new resource group to the application; and

schedule the server in the data center to run the application according to the result of the mapping and the allocation of the new resource group.

14 . The system of claim 8 , wherein the data center is configured to:

detect a change in a workload of the application;

modify at least one resource in the resource group allocated to the application; and

schedule the server in the data center to run the application according to the result of the mapping and the modification to the resource group.

15 . A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions readable by a device to cause the device to:

determine an activation window of an application;

map orbital movements of a low Earth orbit (LEO) satellite data center to the activation window of the application;

allocate a resource group to the application; and

schedule a server in the LEO satellite data center to run the application according to a result of the mapping and the allocation of the resource group.

16 . The computer program product of claim 15 , wherein the device is further caused to:

schedule the server to run the application prior to the LEO satellite data center arriving at an activation region of the application.

17 . The computer program product of claim 15 , wherein the device is further caused to:
