These object are moving in space, and for some reasons, connections are dynamical and can be severely impaired or lost. They have incoming local streams of data (eg HD videos, accelerometer, GPS, other wifi and gsm signals, etc). I would like to abstract the CPU layer, storage layer, and internet connection so that in realtime results of one of my objects are saved if this object dies, so that if one of the object giving internet access to the group loose its connection, the redundancy allows the group of object not to lose internet connection. Can I consider these as different load balancing layers ? Do you recommend to implement this at the kernel layer or at an API layer ? Can I see that as a lightweight cluster ? I think the API is more flexible, especially if I have an heterogeneous (by CPU, OS) set of connected object. However, working at the kernel level allows existing programs not to be rewritten. What are your thoughts ? Do you recommend another list ? Thanks
