Applying Disaster Recovery Techniques in AWS
In this learning activity, the student will investigate different techniques in AWS for disaster recovery. The lesson will present AWS Disaster Recovery techniques and quantify the appropriate use cases, based RTO/RPO, for each technique. The student 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 hardcoded AMI IDs can change. The student will examine a CloudFormation template that has a Lambda function and can retrieve AMIs in real-time. The student will execute this template and verify that an EC2 instance was created.
