the use of snapshots when using immutable functions. It avoids taking a distributed snapshot and uses the local snapshot, resulting in improved performance for OLTP. The sorting speed of varchar, text durable so data is not lost when a virtual machine is stopped. EBS also provides infrastructure snapshot capabilities that can be used to create volume backups. These snapshots can be copied to different only is a little bit slower, but it also requires umount to take a snapshot. This greatly lengthens the time it takes to take a snapshot backup. Disks use the same network as the VMs so you start running
