AWS Storage Gateway for application DR

The AWS Storage Gateway along with EC2 instances is a method to start up your application in AWS in the event your data center is not functioning.

1. Data that is written to your  data center iSCSI volumes is recorded in the AWS Storage gateway in your data center and is asynchronously stored in Amazon S3 (Simple Storage Service) in the form of Amazon EBS (Elastic Block Store) snapshots. 
2.Create an Amazon EBS volume from a the EBS snapshot in S3
3. Start up or create an EC2 Instance from an AMI
4. Mount the EBS volume to an Amazon EC2 instance
5. Use Amazon Route 53 services so users are pointed to the instance running in the cloud.
6,. Restart the application completely from the cloud.
