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 hardcoded 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.

YAML— they both create the same resources).
Navigate to EC2 and create a key pair called
drkeypair. Then, navigate to CloudFormation and create a stack using the URL you copied.
Create a Cross-Stack Reference
Create two CloudFormation stacks:
- Create a stack using the revised version of the original template.
- Create a stack using the
