Configuration Item
Overview
A configuration item is a point-in-time snapshot of the attributes of a supported AWS resource in your account. It contains key components such as metadata, attributes, relationships, current configuration, and related events.
AWS Config automatically creates a configuration item whenever it detects a change in a recorded resource.
Example: If AWS Config is tracking Amazon S3 buckets, it generates a configuration item whenever a bucket is created, updated, or deleted.
Additionally, you can set a custom recording frequency to create configuration items at regular intervals, even if no changes occur.
A configuration item consists of the following components.
