Restrictions on Using AS

AS has the following restrictions:

  • Only applications that are stateless and can be horizontally scaled can run on instances in an AS group. AS automatically releases instances. Therefore, the instances in AS groups cannot be used to save application status information (such as sessions) 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.

  • AS resources must comply with quota requirements listed in Table 1.
