# Tracking migration updates in AWS Migration Hub
<a name="updates-tracking-wt"></a>

To better understand how Migration Hub helps you monitor the progress of a migration, there are three concepts to understand in Migration Hub:
+ Applications
+ Resources (for example, servers)
+ Updates

Migration tools like AWS Application Migration Service (Application Migration Service), AWS Database Migration Service (AWS DMS), and integrated partners' tools send updates to AWS Migration Hub. These updates include information about how a particular resource migration (for example, server or database) is progressing. One or more resources are grouped together to make an application. Each application has a dedicated page in Migration Hub where you can see the updates for all the resources in the application.

When Migration Hub receives an update, it is displayed on the updates page. There can be a delay of up to five minutes for the initial update to appear in the updates page.
