I am running two or more Ubuntu Servers on Amazon EC2. They are all connected to an Elastic Load Balancer so all of the files on each server must be the same. Is there a way that I can just SFTP files to one Ubuntu server and have the files automatically sync across all servers?
There are many synchronization methods or distributed file system solutions out there. Take a look at rsync and its friends for some of the most common sync methods. GlusterFS is a common distributed NAS/filestore solution.
