Systems, methods, apparatuses, and computer program products for supporting remote hosting without using network address translation

An apparatus for supporting remote hosting without using network address translation, the apparatus comprising at least one processor, wherein the at least one processor is configured to cause the apparatus to at least:

• support, at a hub, a plurality of redundant tunnel end points for each of a plurality of spokes using a technology based at least in part on multipoint generic routing encapsulation protocol;
• use policy based routing to determine a destination spoke for outgoing data traffic;
• use service level agreement tracking to select a tunnel end point from the plurality of redundant tunnel end points for the determined destination spoke;
• and
• cause the outgoing data traffic to be routed to the determined destination spoke via the selected tunnel end point.

A computer program product for supporting remote hosting without using network address translation, the computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program instructions stored therein, the computer-readable program instructions comprising:

• program instructions configured to support, at a hub, a plurality of redundant tunnel end points for each of a plurality of spokes using a technology based at least in part on multipoint generic routing encapsulation protocol;
• program instructions configured to use policy based routing to determine a destination spoke for outgoing data traffic;
• program instructions configured to use service level agreement tracking to select a tunnel end point from the plurality of redundant tunnel end points to the determined destination spoke;
• and
• program instructions configured to cause the outgoing data traffic to be routed to the determined destination spoke via the selected tunnel end point.

A system for supporting remote hosting without using network address translation, the system comprising:

• a hub router located at a hub hosting one or more applications for a plurality of remote spokes;
• and
• a plurality of spoke routers, wherein one or more spoke routers are located at each of the plurality of spokes;
• wherein the hub router is configured to:
• support a plurality of redundant tunnel end points for each of the plurality of spokes using a technology based at least in part on multipoint generic routing encapsulation protocol;
• use policy based routing to determine a destination spoke for outgoing data traffic associated with a hosted application;
• use service level agreement tracking to select a tunnel end point from the plurality of redundant tunnel end points for the determined destination spoke;
• and cause the outgoing data traffic to be routed to the determined destination spoke via the selected tunnel end point.
