Systems and methods for managing a multi-region SaaS model

1. A method for providing a multi-region software as a service model, the method comprising:

obtaining a list of allowed regions that can host data of a user from a source region;

automatically assigning a device associated with a new user from the source region to a computing system located in one of the allowed regions, wherein the computing system comprises a cloud instantiation; and

once a new cloud instantiation is generated, determining that another cloud instantiation can be merged into the new cloud instantiation and in response to determining that the another cloud instantiation can be merged into the new cloud instantiation, merging the another cloud instantiation into the new cloud instantiation, wherein it is determined that the another cloud instantiation can be merged into the new cloud instantiation if the another cloud instantiation hosts devices associated with users from source regions that are allowed to be hosted by the new cloud instantiation.

2. The method of claim 1 , further comprising:

obtaining location information from the device during registration; and

determining the source region based on the location information.

3. The method of claim 2 , wherein obtaining the location information is performed by:

gathering location information by the device using at least one of: a hypertext markup language 5 (HTML5) geolocation application programming interface (API), an external geolocation API, a global positioning system (GPS), Wi-Fi triangulation and mobile area code;

determining the source region based on the location information;

displaying the source region to the new user; and

obtaining confirmation from the user if the determined source region is correct and obtaining a corrected source region if not.

4. The method of claim 1 , further comprising optimizing device associations to the cloud instantiation to minimize a number of the cloud instantiations.

5. The method of claim 1 , wherein assigning the device to the cloud instantiation comprises:

checking whether an existing cloud instantiation exists in one of the allowed regions; and

if one or more existing cloud instantiations exist in one of the allowed regions, assigning the device to one of the existing cloud instantiations; and

otherwise, creating a new cloud instantiation in one of the allowed regions and assigning the device to the new cloud instantiation.

6. The method of claim 1 , further comprising:

if one cloud instantiation exists in one of the allowed regions, assigning the device to the existing cloud instantiation; and

if more than one cloud instantiations exist in one of the allowed regions, then:

selecting one of the existing cloud instantiations based on one or more criteria; and

assigning the device to the selected cloud instantiation.

7. The method of claim 1 , further comprising if more than one cloud instantiations exist in one of the allowed regions, assigning the device to the existing cloud instantiation that is geographically closest to the source region.

8. The method of claim 1 , further comprising if more than one cloud instantiations exist in one of the allowed regions, assigning the device to the existing cloud instantiation that is the most inexpensive.

9. A system for providing a multi-region software as a service model, the system comprising:

a memory;

a processor configured to:

obtain a list of allowed regions that can host data of a user from a source region;

automatically assign a device associated with a new user from the source region to a computing system located in one of the allowed regions, wherein the computing system comprises a cloud instantiation; and

once a new cloud instantiation is generated, the processor is configured to determine whether another cloud instantiation can be merged into the new cloud instantiation and if so, merge the another cloud instantiation into the new cloud instantiation, wherein the processor is configured to determine that the another cloud instantiation can be merged into the new cloud instantiation if the another cloud instantiation hosts devices associated with users from source regions that are allowed to be hosted by the new cloud instantiation.

10. The system of claim 9 , wherein the processor is configured to:

obtain location information from the device during registration; and

determine the source region based on the location information.

11. The system of claim 10 , wherein the processor is configured to obtain the location information by:

gathering location information by the device using at least one of: a hypertext markup language 5 (HTML5) geolocation application programming interface (API), an external geolocation API, a global positioning system (GPS), Wi-Fi triangulation and mobile area code;

determining the source region based on the location information;

displaying the source region to the new user; and

obtaining confirmation from the user if the determined source region is correct and a corrected source region if not.

12. The system of claim 9 , wherein the processor is configured to optimize device associations to the cloud instantiation to minimize a number of the cloud instantiations.

13. The system of claim 9 , wherein the processor is configured to assign the device to the cloud instantiation by:

checking whether an existing cloud instantiation exists in one of the allowed regions; and

if one or more existing cloud instantiations exist in one of the allowed regions, assigning the device to one of the existing cloud instantiations,

and otherwise, creating a new cloud instantiation in one of the allowed regions and assigning the device to the new cloud instantiation.

14. The system of claim 9 , wherein the processor is configured to:

if one cloud instantiation exists in one of the allowed regions, assign the device to the existing cloud instantiation; and

if more than one cloud instantiations exist in one of the allowed regions, then:

select one of the existing cloud instantiations based on one or more criteria; and

assign the device to the selected cloud instantiation.
