 ** CloudFormation **   <a name="DevOpsGuru-Type-UpdateResourceCollectionFilter-CloudFormation"></a>
 A collection of AWS CloudFormation stacks. You can specify up to 1000 AWS CloudFormation stacks.   
Type: [UpdateCloudFormationCollectionFilter](API_UpdateCloudFormationCollectionFilter.md) object  
Required: No

 ** Tags **   <a name="DevOpsGuru-Type-UpdateResourceCollectionFilter-Tags"></a>
The updated AWS tags used to filter the resources in the resource collection.  
Tags help you identify and organize your AWS resources. Many AWS services support tagging, so you can assign the same tag to resources from different services to indicate that the resources are related. For example, you can assign the same tag to an Amazon DynamoDB table resource that you assign to an AWS Lambda function. For more information about using tags, see the [Tagging best practices](https://docs.aws.amazon.com/whitepapers/latest/tagging-best-practices/tagging-best-practices.html) whitepaper.   
Each AWS tag has two parts.   
+ A tag *key* (for example, `CostCenter`, `Environment`, `Project`, or `Secret`). Tag *keys* are case-sensitive.
+ An optional field known as a tag *value* (for example, `111122223333`, `Production`, or a team name). Omitting the tag *value* is the same as using an empty string. Like tag *keys*, tag *values* are case-sensitive.
Together these are known as *key*-*value* pairs.  
When you create a *key*, the case of characters in the *key* can be whatever you choose. After you create a *key*, it is case-sensitive. For example, DevOps Guru works with a *key* named `devops-guru-rds` and a *key* named `DevOps-Guru-RDS`, and these act as two different *keys*. Possible *key*/*value* pairs in your application might be `Devops-Guru-production-application/RDS` or `Devops-Guru-production-application/containers`.
Type: Array of [UpdateTagCollectionFilter](API_UpdateTagCollectionFilter.md) objects
