# Tagging in AMS Accelerate
<a name="acc-tagging"></a>

Most Accelerate features (patching, backup, monitoring) use *tags* and *configuration profiles* to decide which of your resources to manage, what actions to apply, and when to apply them. Tags are labels that you apply to resources. Configuration profiles contain rules based on those tags.

Each Accelerate feature has its own tagging requirements. Some features require you to use specific tags, while others allow you to use any of your own.

For information about required tags, see [Customer-managed tags in Accelerate](acc-tag-req.md).

For information about tags that can be defined customers, see [Customer-provided tags in Accelerate](acc-tag-cust-provided.md)
