Lab description

AWS Secrets Manager is a fully-managed service for managing sensitive digital credentials. Types of secrets that can be managed with AWS Secrets Manager include API keys, passwords, tokens, and certificates. AWS Secrets Manager also addresses the security and maintenance concerns that come with hardcoding sensitive pieces of data directly in your code.

With AWS Secrets Manager, you can replace hard-coded credentials in your code by retrieving the secret programmatically using an AWS Secrets API call.

In this lab, you will migrate a hard-coded API key in an AWS Lambda function to AWS Secrets Manager. You will also update the function code to follow a secure pattern that is easier to maintain.
