Eventually-consistent message delivery system for edge applications

A system comprising:

• one or more processors;
• and
• one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause a site router agent at an edge site to:
• determine that a first application instance becomes running on the edge site, wherein the first application instance is associated with a first unique identifying information comprising a first globally unique identifying information and a first locally unique identifying information;
• send, to a control plane of an edge backend, a report indicating that the first application instance becomes available at the edge site, the report comprising the first locally unique identifying information;
• retrieve, from a message router at the edge backend, a first message;
• determine, based on a destination field of the first message, that the first message is destined to the first application instance;
• store the first message into a storage communicatively connected to the site router agent;
• establish a network connection with the first application instance;
• and
• send, upon establishing the network connection, the first message to the first application instance.

One or more computer-readable non-transitory storage media embodying software that is operable when executed to, by a site router agent at an edge site to:

• determine that a first application instance becomes running on the edge site, wherein the first application instance is associated with a first unique identifying information comprising a first globally unique identifying information and a first locally unique identifying information;
• send, to a control plane of an edge backend, a report indicating that the first application instance becomes available at the edge site, the report comprising the first locally unique identifying information;
• retrieve, from a message router at the edge backend, a first message;
• determine, based on a destination field of the first message, that the first message is destined to the first application instance;
• store the first message into a storage communicatively connected to the site router agent;
• establish a network connection with the first application instance;
• and
• send, upon establishing the network connection, the first message to the first application instance.
