# AWS::Glue::Workflow
<a name="aws-resource-glue-workflow"></a>

The `AWS::Glue::Workflow` is an AWS Glue resource type that manages AWS Glue workflows. A workflow is a container for a set of related jobs, crawlers, and triggers in AWS Glue. Using a workflow, you can design a complex multi-job extract, transform, and load (ETL) activity that AWS Glue can execute and track as single entity.

## Syntax
<a name="aws-resource-glue-workflow-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:
