Applying Disaster Recovery Techniques in AWS
In this lab, you will be presented with AWS disaster recovery techniques and go over the appropriate use cases, based on RTO/RPO, for each technique. You will then utilize a CloudFormation template to recover a large environment with many AWS resources. This exercise will show that CloudFormation is a viable option for all but the most aggressive recovery timeline. A risk in using CloudFormation in disaster recovery is that hard-coded AMI IDs can change. You will examine a CloudFormation template that has a Lambda function and can retrieve AMIs in real time. You will execute this template and verify that an EC2 instance was created.
