Data transfer into Amazon's cloud is completely free.  Data out is what costs money.  See http://aws.amazon.com/pricing_effective_july_2011/

What you're trying to do here would be loading data *into* amazon from our main server at usegalaxy.org.  I'm not sure what you're asking with the second question there -- in a cloud instance the master and worker nodes are all inside the cloud, and communication between them is both free, and very fast.

Good Morning Dannon

this may not be a cost effective way of sharing data, cloud amazon charges $0.120 per GB data transfer, is there a work around ?

also does that mean a worker node cannot communicate with master instance directly and use same below protocol to share history ?

Thanks

Hi,

That sort of sharing only works within a single galaxy instance; users are not shared between different galaxies.  To copy an entire history from one instance to another you will want to use the history export/import functionality.  History context menu -> Export to file on the source instance, and Import from file on the destination.

Hello Team Galaxy 

trying to share/ forward dataset history from user 1 ( running on a local instance,Scrn.1) to user 2 (running on cloud amazon ec2 instance,Scrn.2) and vice-versa, error:- user is not a valid galaxy user. getting this error while both the users are logged into system and both the instance's are running normal.


insights of team will be very helpful.
