A highly scalable primary server is provided to serve an increasing number of users and remote devices. Instead of communicating with a primary server using an expensive communication protocol, a remote device communicates with a secondary server using a less expensive protocol to determine whether the primary server desires to communicate control instructions to the remote device. When the primary server has a request to control the remote device, the primary server creates a table entry to the secondary server to notify the remote device of a request to communicate. Upon polling the secondary server and learning of the created table entry, the remote device establishes a communication connection with the primary server to receive the instructions for controlling the remote device. In this manner, the demand for resources needed for communication with the primary server is significantly reduced. |
