An Extensible Framework for Observatory System Based on Docker Cloud

Remote observatory is playing more and more important role in scientific research, astronomy education and citizen science. With many years' development, remote observatory whether hardware or software has made great progress. It supports single telescope well and has been very mature. For high utility rate of an observatory, more and more observatories has began to run multiple telescopes to provide more observation services. But it also takes some challenges, for example how to manage telescopes, how to manage lots of observers, how to update driver or application quickly and how to realize coordination and cooperation between different telescopes. After taking into full consideration of the problems, we propose an extensible framework for observatory system based on Docker cloud. It not only could solve that challenges from multi telescopes, but also could make software application to support more hardware platform easily.
