To ensure the smooth operation and security of your hybrid and Infrastructure as a Service (IaaS) deployment in Microsoft Azure SQL Solutions, it is vital to apply patches and updates regularly. The process of applying patches involves installing the latest fixes, enhancements, and security updates provided by Microsoft. This article will guide you on how to apply patches and updates effectively in different Azure SQL deployment scenarios.
Azure SQL Managed Instance handles all patching and updating processes, significantly reducing your administrative efforts. It automatically installs the latest security updates during the maintenance window. However, you need to update minor and major version upgrades manually. To do so, follow these steps:
sql
SELECT * FROM sys.dm_db_patching_status
sql
ALTER DATABASE CURRENT SET EMERGENCY
ALTER DATABASE CURRENT SET SINGLE_USER WITH ROLLBACK IMMEDIATE
sql
SELECT * FROM sys.dm_db_patching_status
Azure SQL Database has an automatic patching feature enabled by default. It automatically installs security updates during the maintenance window, reducing the risk of vulnerabilities. However, you can manually upgrade the minor version to benefit from the latest performance improvements and bug fixes. Follow these steps to apply the patch:
When running SQL Server on Azure VMs, you have complete control over patching and updating processes. However, it is essential to follow best practices to avoid interruptions and maintain security. Use the following steps as a guideline:
Note: Always make a backup before applying patches/upgrades to a SQL Server VM.
For hybrid deployments involving on-premises SQL Servers integrated with Azure, you must follow standard SQL Server patching procedures. Here is a general outline of the process:
In conclusion, applying patches and updates is crucial to maintaining a secure and efficient hybrid and IaaS deployment in Microsoft Azure SQL Solutions. Whether you are using Azure SQL Managed Instance, Azure SQL Database, SQL Server on Azure VMs, or a hybrid deployment, regularly installing updates and patches ensures you benefit from the latest features, security enhancements, and bug fixes provided by Microsoft. Remember to always follow best practices, review release notes, perform backups, and plan maintenance windows for a smooth patching experience.
