Keeping the IoT system up and running with almost zero downtime is extremely important. Critical applications such as medical equipment, traffic control signals, and power grids are implementing IoT. The high availability of IoT applications that include end devices, gateway devices, mobile and desktop applications and cloud services becomes of paramount importance.

The solution is to make sure we have our systems up and running all the time. The implementation of an IoT system should take advantage of multicluster architecture, where we have one primary and multiple secondary systems running, which are in sync. In case of the failure of the primary systems, the secondary system takes the lead and becomes the primary without any downtime and keeps the system running.
