You can use System Extender Business Rules with Azure Server Sets for enhanced scalability at the Azure Database and Server Sets level. You can perform Server and eDTU scaling manually or using System Business Rules. If System Business Rules is selected as a Scaling Type, then a user-defined System Extender Business Rule determines if scaling is needed. You must implement the scaling function and return the proper scaling object by adding a System Extender Business Rule and assigning it appropriately.
Under each Case statement, use these rules and related Args and BRApis to check the current Server Set capacity, query metrics about a Server Set or Azure Database, and identify the impact of the Server Sets volume or level of Azure Database deployed. See "Azure Database Connection Setting and Server Sets" in the Installation and Configuration Guide.
