Parameter Store is a hierarchical storage to manage your credentials, configurations, and sensitive information. It allows you to create parameters to manage your passwords, configurations, database information, and AMI values. These parameters can be used in applications.
In this Cloud Lab, you’ll first provision an EC2 instance using the CloudFormation (CFN) template, then create parameters in the Parameter Store and use them in the CFN template. You’ll also use the public parameters given by the AWS services in the CFN template. You’ll add parameter policies, create an SNS topic and subscription, create an Amazon EventBridge rule, and trigger the events.
After completing this Cloud Lab, you’ll be able to use the Parameter Store to save configuration variables, custom settings, IDs, keys, and more.
The following is a high-level architecture diagram of the infrastructure that you’ll create in this Cloud Lab:
