Preparation

In this section, we will perform the necessary resource preparation steps before building the anomaly detection system, including:

1. Create S3 bucket: Used to store the source code of the AWS Lambda function.
2. Create EBS volume: Create a target Amazon EBS volume for the system to perform backups on.
3. Create resources with CloudFormation: Automatically deploy other core resources (such as DynamoDB table, EventBridge rule, CloudWatch alarm, SNS topic, Lambda function…) using the provided template.
