 ### Automatic tuning for SQL Database
 
-Automatic tuning for Azure SQL Database uses the **CREATE INDEX**, **DROP INDEX**, and **FORCE LAST GOOD PLAN** database advisor recommendations to optimize your database performance. For more information, see [Database advisor recommendations in the Azure portal](database-advisor-find-recommendations-portal.md), in [PowerShell](/powershell/module/az.sql/get-azsqldatabaserecommendedaction), and in the [REST API](/rest/api/sql/serverautomatictuning).
+Automatic tuning for Azure SQL Database uses the **[CREATE INDEX](/sql/t-sql/statements/create-index-transact-sql?view=azuresqldb-current&preserve-view=true)**, **[DROP INDEX](/sql/t-sql/statements/drop-index-transact-sql?view=azuresqldb-current&preserve-view=true)**, and **FORCE_LAST_GOOD_PLAN** database advisor recommendations to optimize your database performance. For more information, see [Database advisor recommendations in the Azure portal](database-advisor-find-recommendations-portal.md), in [PowerShell](/powershell/module/az.sql/get-azsqldatabaserecommendedaction), and in the [REST API](/rest/api/sql/serverautomatictuning).
 
 You can either manually apply tuning recommendations using the Azure portal, or you can let automatic tuning autonomously apply tuning recommendations for you. The benefits of letting the system autonomously apply tuning recommendations for you is that it automatically validates there exists a positive gain to workload performance, and if there is no significant performance improvement detected or if performance regresses, the system automatically reverts the changes that were made. Depending on query execution frequency, the validation process can take from 30 minutes to 72 hours, taking longer for less frequently executing queries. If at any point during validation a regression is detected, changes are reverted immediately.

-To monitor the performance of a database in Azure SQL Database and Azure SQL Managed Instance, start by monitoring the CPU and IO resources used by your workload relative to the level of database performance you chose in selecting a particular service tier and performance level.
