In Alibaba Cloud's Elastic Scaling Service, the states for a scaling activity represent the various stages that a scaling operation can go through as it is initiated, processed, or completed.

The states "In-Progress," "Success," and "Cancelled" all describe valid scenarios for scaling activities.

- "In-Progress" indicates that the scaling operation is currently being executed.

- "Success" signifies that the scaling action has been completed successfully.

- "Cancelled" shows that the scaling operation was aborted before it could reach a final state.

In contrast, "Timeout" is not recognized as a valid state within the context of scaling activities in this service. While a scaling action could fail to complete within a certain time frame due to various factors (which might be informally referred to as timing out), this is not officially documented as a state. Thus, it does not represent a distinct phase of a scaling operation like the others do.

Understanding these states is important for monitoring and managing scaling operations effectively, ensuring that any issues can be identified and addressed promptly.
