Thank you very much for the information.
For the last part of using ec2 instances at aws, is there an option that I can control galaxy's operation at aws site? This way I can start/stop the instance when I need. I am not willing to terminate the instance since everything will be lost.
We'd recommend you not ever stop/start through the aws console -- this is basically guaranteed to cause problems with your instance. Always use the cloudman interface (on your ec2 instance -- http://<ec2_instance>/cloud) to terminate, and then use usegalaxy.org/cloudlaunch to restart it.
Meantime, I am wondering the data structure on ec2 galaxy instance. Where is the location for the data uploaded from the galaxy gui? If I ssh the Ubuntu, where is the data directory for holding the work?
Everything will be in /mnt/galaxyData/files (which is symlinked to /mnt/galaxyTools/galaxy-central/database/files). Note that the filenames will be by id (like files/000/dataset_001.dat is dataset id 1, etc), and not particularly accessible in this format without a little extra legwork.
