Maintaining reachability of apps moving between fog and cloud using duplicate endpoint identifiers

摘要

Techniques are disclosed for maintaining reachability of an application moving between a central cloud network and a fog network using duplicate endpoint identifiers. Network characteristics of a cloud environment are monitored. The cloud environment includes a central cloud network and a fog network. A server in the central cloud network hosts an application that serves a client device. The application is assigned an endpoint identifier that is mapped to a locator identifier associated with the central cloud network. It is determined that a condition for moving the application to the fog network is satisfied based on the monitored network characteristics. An instance of the application is installed on a server in the fog network. The endpoint identifier is assigned to the application instance and mapped to a locator identifier associated with the fog network.
