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.

Create a CloudFormation Stack
-
Navigate to S3, open the provided S3 bucket, and copy the URL of one of the provided templates (
JSONorYAML— 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.

Challenge
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
AMILookuptemplate.
