Systems, methods, and apparatuses for tenant-to-tenant failover in a multi-tenant cloud computing environment

A system to execute within a host organization, wherein the system comprises:

• a processor and a memory to execute instructions at the system;
• software instructions that, when executed by the processor, cause the system to:
• identify, by a first name in a name space, a first one of a plurality of tenants in a multi-tenant cloud computing system as a primary tenant for providing a function to other of the plurality of tenants in the multi-tenant cloud computing system;
• associate the first name in the name space with a first address in an address space;
• identify, by a second name in the name space, a second one of the plurality of tenants in the multi-tenant cloud computing system as a secondary tenant for providing the function to the other of the plurality of tenants should the primary tenant become unavailable;
• associate the second name in the name space with a second address in an address space;
• provide the function to the other of the plurality of tenants in the multi-tenant cloud computing system via the primary tenant when the primary tenant is available;
• and
• switch to providing the function to the other of the plurality of tenants in the multi-tenant cloud computing environment via the secondary tenant when the primary tenant is unavailable and the secondary tenant is available with software instructions that, when executed by the processor, cause the system to:
• replace the association of the first name in the name space with the first address in the address space by newly associating the first name in the name space with the second address in the address space;
• receive a request to access the function, the request specifying the first name in the name space associated with the primary tenant;
• fetch the second address in the address space newly associated with the first name in the name space;
• and
• provide access to the function via the secondary tenant located at the second address.

Non-transitory computer readable storage media having instructions stored thereon that, when executed by a processor of a system, cause the system to:

• identify, by a first name in a name space, a first one of a plurality of tenants in a multi-tenant cloud computing system as a primary tenant for providing a function to other of the plurality of tenants in the multi-tenant cloud computing system;
• associate the first name in the name space with a first address in the address space;
• identify, by a second name in the name space, a second one of the plurality of tenants in the multi-tenant cloud computing system as a secondary tenant for providing the function to the other of the plurality of tenants should the primary tenant become unavailable;
• associate the second name in the name space with a second address in the address space;
• provide the function to the other of the plurality of tenants in the multi-tenant cloud computing system via the primary tenant when the primary tenant is available;
• and
• switch to providing the function in the multi-tenant cloud computing environment via the secondary tenant when the primary tenant is unavailable and the secondary tenant is available with software instructions that, when executed by the processor, cause the system to:
• replace the association of the first name in the name space with the first address in the address space by newly associating the first name in the name space with the second address in the address space;
• receive a request to access the function, the request specifying the first name in the name space associated with the primary tenant;
• fetch the second address in the address space newly associated with the first name in the name space;
• and
• provide access to the function via the secondary tenant located at the second address.
