 While EBS snapshots operate independently from the guest OS running on the EC2 instance, the similarity to VMware snapshots ends there. An EBS snapshot saves the data of the source EBS volume, but does not save the state or memory of the EC2 instance to which the volume is attached. Also unlike with VMware, EBS snapshots can be created for an OS volume only while leaving any separate application volumes as is.
 
-Automating EBS snapshot creation and rollback is fairly straightforward assuming your playbooks can access the required AWS APIs. The tricky bit of the automation is identifying the EC2 instance and attached EBS volume that corresponds to the target host in the Ansible inventory managed by AAP, but this can be solved by setting idenifying tags on your EC2 instances.
