AWS Adds Update Controls for Amazon RDS Custom for SQL Server

Amazon Web Services has introduced operating system update controls for Amazon RDS Custom for SQL Server, allowing administrators to manage OS-level updates more directly. The feature enables customers to apply, schedule and control operating system patches within RDS Custom environments. Unlike standard managed database services, RDS Custom is designed for workloads that require deeper control over the underlying infrastructure, including OS configurations.

To view the updates, customers can use the describe-pending-maintenance actions API to apply updates immediately or schedule accordingly. The update allows organizations to align OS patching with internal policies and maintenance windows, which can be important for applications with strict compliance or uptime requirements. AWS said the feature is intended to provide flexibility while maintaining the benefits of a managed database service. Enterprises running regulated or legacy workloads often require greater control over patching and system configurations. The feature is available in all AWS regions where RDS Custom for SQL Server is available.
