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.

  1. Challenge

    Create a CloudFormation Stack

    • Navigate to S3, open the provided S3 bucket, and copy the URL of one of the provided templates (JSON or 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.

  2. 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 AMILookup template.
