RDS Custom for SQL Server Deep Dive

Proposed session for SQLBits 2026

TL; DR

Unlock the full potential of RDS Custom for SQL Server: combining managed database benefits with OS/database customization. Learn architecture, advanced configurations, and real-world optimization strategies.

Session Details

Amazon RDS Custom for SQL Server represents a significant evolution in managed database services, bridging the gap between traditional RDS and self-managed instances. This deep dive session will take you beyond the basics, exploring how RDS Custom enables both the convenience of a managed service and the flexibility of customization that database administrators require for specialized workloads.

We'll start by examining the architectural foundations of RDS Custom for SQL Server, including its automation framework and the critical boundaries of the support perimeter. You'll learn how the service maintains its managed status while allowing unprecedented levels of access to both the operating system and database engine.

The session will then dive into advanced configurations, covering custom parameter groups, OS-level modifications, and database engine customizations that aren't possible with standard RDS. We'll explore practical scenarios for implementing SQL Server features that traditionally required self-managed EC2 instances, such as custom CLR integration, linked servers, specialized agents, and advanced security configurations.

Whether you're considering RDS Custom for new deployments or migrating existing workloads, this session will equip you with the knowledge to make informed decisions and maximize your investment in this powerful database platform.
