Techniques are disclosed for facilitating inter-container communications, via a cloud exchange, for containers executing at logically isolated networks. In one example, the techniques of the disclosure provide a method including sending, by a container to a cloud exchange via an application programming interface exposed by an interconnection platform of the cloud exchange, container registration data for the container, the container registration data including a network address for a host that executes the container and a container identifier for the container. Further techniques are disclosed for applications of inter-container communications via a cloud exchange, including hot swapping and hot scaling containers between cloud services, and automated disaster recovery across containers from a failed cloud service to a backup cloud service.
