IoT servers & WEB Applications
IoT Servers are not your plain vanilla servers, as you know them in business software servers, or web-application servers (although they are perfectly usable for these purposes). IoT Servers are more like large telephone exchange servers if you think about it. They need to be able to handle large numbers of parallel communications, a problem in 1 conversation should never impact the whole system but the problem should always be contained to this 1 problematic conversation. They need to be very robust and can never go down, even for maintenance, and should be ready for explosions in number of connections and traffic.
