A method, system, and computer program product for Internet of Things (IoT) network-connected devices. Embodiments include methods and systems for registering one or more listener devices (e.g., mobile phones or tablets, etc.) to receive messages from one or more notification devices (e.g., web cameras, etc.). A notification server is selected from among multiple notification servers to receive notification messages from the notification devices and then to forward (e.g., through a push service, etc.) portions of or variations of the notification messages to the listener devices. In some embodiments, the selection of the notification server is based on load balancing between the multiple notification servers and/or push servers. In some embodiments, the selection of a notification server and/or push server is based on a provisioning file.
