I have a few questions, since the recent Amazon Cloudburst.
- Is it true, that attaching EBS as an external volume gives a better I/O performance than using EBS as a root device?
- How does IO take place between an instance and EBS volume mounted as
- Root Device.
- External volume. (Is it via the ethernet or on the same XEN server, or any other)
Since I am charged I/O on an external EBS, am I correct in guessing that the EBS volumes are in a different location than the instances?
