Nikita gave Scalar presentation at Jazoon last June and the video for it has just been published. Although Scalar and GridGain 3.0 have significantly evolved since then, this is still a very nice and educational video to watch. It has a nice cloud computing discussion in the beginning and Live Coding Session towards the last 30 minutes. If you are not interested in discussion and would like to watch only the coding session - start watching from the middle.
