What Are Restrictions on Using AS?
Only applications that are stateless and can be horizontally scaled can run on instances in an AS group. AS automatically releases ECS instances. Therefore, the instances in AS groups cannot be used to save application status information (such as session statuses) and related data (such as database data and logs).
If the application status or related data must be saved, you can store the information on separate servers.
Table 1 lists the AS service resource quotas.

| AS group | Maximum number of AS groups that you can create | 10 |

| AS policy | Maximum number of AS policies that can be added to an AS group | 10 |
| Instance | Maximum number of instances that can be added to an AS group | 300 |
| Bandwidth scaling policy | Maximum number of bandwidth scaling policies that you can create | 10 |
