Application Migration Service sends events to Amazon EventBridge whenever a Source server launch has completed, a Source server reaches the READY_FOR_TEST lifecycle state for the first time, and when the data replication state becomes Stalled or when the data replication state is no longer Stalled . You can use EventBridge and these events to write rules that take actions, such as notifying you, when a relevant event occurs. For more information, see What is Amazon EventBridge?
AWS Application Migration Service sends events on a best-effort basis to EventBridge. Event delivery is not guaranteed.
