1. A method for object recognition performed by an augmented reality system, the method comprising: receiving, by a computing device and from a device of a user, an image; determining, by the computing device, channels of content to which the user is subscribed; determining, by the computing device, a list of servers in a cluster of servers that host the determined channels of content; selecting, by the computing device, at least one server from the determined list of servers to be used to query the channels of content to which the user is subscribed; querying, by the computing device, the selected servers for the channels of content to which the user is subscribed with the image to determine at least one object that matches the image from object databases for the channels to which the user is subscribed; retrieving, by the computing device, content associated with the determined at least one object; and sending, by the computing device, the retrieved content to the user.
