Introduction to Amazon RDS Custom¶
Amazon Relational Database Service (RDS) Custom is an innovative service designed to provide a high degree of control over database configurations while benefitting from the scalability and management capabilities of Amazon RDS. With support for SQL Server now including the latest Cumulative Updates (CU) and General Distribution Release (GDR) updates for Microsoft SQL Server, this guide will delve into what these updates entail, their importance to your RDS Custom environment, and how to implement them effectively.
Using Amazon RDS Custom for SQL Server is a strategic choice for businesses that need to tailor their database services to specific requirements while ensuring the latest security measures and performance enhancements are in place.
What Are Cumulative Updates and GDRs?¶
Understanding Cumulative Updates (CUs)¶
Cumulative Updates are substantial packages from Microsoft that incorporate all previously released fixes, updates, and hotfixes for SQL Server. This approach eliminates the need to deploy individual patches, thus simplifying the upgrade process and ensuring comprehensive coverage of potential issues.
- Benefits of CUs:
- Simplified upgrade process
- Inclusion of critical bug fixes and enhancements
- Better system stability and performance
Understanding General Distribution Releases (GDRs)¶
GDRs, on the other hand, focus primarily on addressing specific high-severity issues and security vulnerabilities without adding new features or functionalities. GDRs are generally used for urgent patches that protect systems from known threats, thereby ensuring that your database environment remains secure.
- Benefits of GDRs:
- Rapid deployment of security patches
- Focus on stability and security over new features
- Reduction in potential vulnerabilities

Understanding SQL Server Versioning¶
To fully appreciate the significance of the latest updates (such as SQL Server 2019 CU32+GDR and SQL Server 2022 CU25), it’s essential to understand the versioning structure that Microsoft employs for SQL Server products.
The version numbers provide critical information regarding the SQL Server build, features, and the extent of any fixes provided through the updates. Each version culminates in a unique identifier that indicates the build number and the type of release, allowing administrators to quickly grasp the updates’ context and application.
- Example Versions:
- SQL Server 2019 Version: 15.00.4480.2.v1
- SQL Server 2022 Version: 16.00.4262.2.v1
