Once cataloged, your data is immediately searchable, queryable, and available for ETL. AWS Glue generates the code to execute your data transformations and data loading processes. AWS Glue generates Python code that is entirely customizable, reusable, and portable. Once your ETL job is ready, you can schedule it to run on AWS Glue's fully managed, scale-out Spark environment. AWS Glue provides a flexible scheduler with dependency resolution, job monitoring, and alerting. AWS Glue is serverless, so there is no infrastructure to buy, set up, or manage. It automatically provisions the environment needed to complete the job, and customers pay only for the compute resources consumed while running ETL jobs. With AWS Glue, data can be available for analytics in minutes.

For example, you might use AWS Database Migration Service, AWS Server Migration Service, and partner migration tools to migrate an application comprised of a database, virtualized web servers, and a bare metal server. Using Migration Hub will provide you with a single screen that shows the migration progress of all the resources in the application. This allows you to quickly get progress updates across all of your migrations, easily identify and troubleshoot any issues, and reduce the overall time and effort spent on your migration projects. Migration Hub is available to all AWS customers at no additional charge. You only pay for the cost of the migration tools you use, and any resources being consumed on AWS.
