EBS
·
To create snapshot of the root EBS
volume ; should stop the instance first. However can take a snapshot while the
instance is running; snapshots are incremental , the delta is copied to S3
·
Can create AMI`s from both Volumes
and snapshots
·
Can modify EBS volumes on the fly;
including storage type and size.
·
Volumes will always be in the same AZ
as the ec2 instance
·
To move an EC2 instance from one AZ
to another; Take a snapshot of it; create an ami of
the snapshot and then use the AMI to launch the ec2 instance in a new AZ.
·
To move an EC2 instance from one
region to another; take a snapshot of it, create an ami
instance of the snapshot and copy the AMI to another region , Then use the
copied AMI to launch a new instance in another region
·
for encryption of root volume take a snaphot then copy it and select encrypt option, then create AMI and launch
EBS OPTIMIZED
SSD BURSTABLE
o GP2
has 3 IOPS per meg, volumes under 1000 meg can burst to 3k iops'
also can increase the size of the volume (> 5334 GB) to get a total ok 16k
IOPS before moving to io1

If you Terminate an Instance only the
root volume is deleted (by default) other EBS volumes persist
