Achieve near-zero downtime database maintenance by using blue/green deployments with AWS JDBC Driver

In this post we introduce the blue/green deployment plugin for the AWS JDBC Driver, a built-in plugin that automatically handles connection routing, traffic management, and switchover detection during blue/green deployment switchovers. We show you how to configure and use the plugin to minimize downtime during database maintenance operations during blue/green deployment switchovers.

Essential tools for monitoring and optimizing Amazon RDS for SQL Server

In this post, we demonstrate how you can implement a comprehensive monitoring strategy for Amazon RDS for SQL Server by combining AWS native tools with SQL Server diagnostic utilities. We explore AWS services including AWS Trusted Advisor, Amazon CloudWatch Database Insights, Enhanced Monitoring, and Amazon RDS events, alongside native SQL Server tools such as Query Store, Dynamic Management Views (DMVs), and Extended Events. By implementing these monitoring capabilities, you can identify potential bottlenecks before they impact your applications, optimize resource utilization, and maintain consistent database performance as your business scales.

Trigger AWS Lambda functions from Amazon RDS for SQL Server database events

The ability to invoke Lambda functions in response to Amazon RDS for SQL Server database events enables powerful use cases such as triggering automated workflows, sending real-time notifications, calling external APIs, and orchestrating complex business processes. In this post, we demonstrate how to enable this integration by using Amazon CloudWatch subscription filters, Amazon SQS, and Amazon SNS to invoke Lambda functions from RDS for SQL Server stored procedures, helping you build responsive, data-driven applications.

Managing IP address exhaustion for Amazon RDS Proxy

In this post, you will learn how to address IP address exhaustion challenges when working with Amazon RDS Proxy. For customers experiencing IP exhaustion with RDS Proxy, migrating to IPv6 address space can be an effective solution if your workload supports IPv6. This post focuses on workloads that cannot support IPv6 address space and provides an alternative approach using IPv4 subnet expansion. The solution focuses on expanding your Amazon Virtual Private Cloud (Amazon VPC) CIDR range, establishing new subnets, and executing a carefully planned switching of your proxy to a new subnet configuration.
