# DMS Event Subscription

DMS Event Subscription in AWS Database Migration Service allows you to receive notifications about important events related to your migration tasks and replication instances. By creating a subscription, you can specify which event categories to monitor and which Amazon SNS topic to use for delivering notifications. This helps you stay informed about status changes, errors, or other significant activities during database migrations.
