AWS Secrets Manager: Overview and Configuration Example

AWS Secrets Manager is a service that helps you protect access to your applications, services, and IT resources without the upfront investment and on-going maintenance costs of operating your own infrastructure. It enables you to rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. Here's a detailed overview of AWS Secrets Manager along with a configuration example:
