The increasing complexity of today's connected devices creates a new set of requirements on remote management and fault tolerance. The problems of doing secure, reliable and efficient mobile communication paired with remote maintenance are often severely underestimated, thus ending up consuming a large portion of the development budget. Linux + Erlang is a powerful combination with built in fault tolerance, upgrade procedures, distributed programming and a strong affinity for mobile communication. The speech goes through the problem set and how Linux/Erlang can be used to solve it. The audience are embedded developers and manager interested in where the connected devices field is heading, and how Linux/Erlang can help them lower their development cost and risk exposure in this area. Attending people are expected to have basic knowledge about embedded systems and mobile communication.
