Specifies the types of AWS resource for which AWS Config records configuration changes.
In the recording group, you specify whether all supported types or specific types of resources are recorded.
By default, AWS Config records configuration changes for all supported types of regional resources that AWS Config discovers in the region in which it is running. Regional resources are tied to a region and can be used only in that region. Examples of regional resources are EC2 instances and EBS volumes.
You can also have AWS Config record configuration changes for supported types of global resources (for example, IAM resources). Global resources are not tied to an individual region and can be used in all regions.
The configuration details for any global resource are the same in all regions. If you customize AWS Config in multiple regions to record global resources, it will create multiple configuration items each time a global resource changes: one configuration item for each region. These configuration items will contain identical data. To prevent duplicate configuration items, you should consider customizing AWS Config in only one region to record global resources, unless you want the configuration items to be available in multiple regions.
If you don't want AWS Config to record all resources, you can specify which types of resources it will record with the resourceTypes parameter.
For a list of supported resource types, see Supported resource types.
