Our Way Out

  • fault tolerance
  • scalability
  • relatively low cost — the video surveillance service should pay off
  • reliability — provided that one hard drive starts to work slowly or fails, this should not affect the rest of the system
  • the ability to not only save, but also to distribute video
  • maximum simplicity of design: we have no desire, ability and need to get involved in writing our own file system
