I have an Amazon ec2 linux instance, with a separate EBS drive, 500Gb in size of which there is 80Gb of data. I want to share this data with a couple of other ec2 instances that I will be creating shortly, and just wondering what is the best way to do this.
Should I just rsync the data between them, or is there a way to mout the same EBS on two different instances at the same time?
I could also take a snapshot of the drive, and then when I provision the other instances I could specify to use that snapshot?
Which is the preferred way? The data is not going to change, it just needs read access.
