Architecture Diagram: AWS architecture diagram showing RDS Multi-AZ DB Cluster connected to CloudWatch Alarm, which triggers a Lambda Function to scale storage. The alarm also sends notifications to Amazon SNS. The components are arranged in a workflow with connecting arrows, displayed within a blue-bordered region box.

Automatically scale storage for Amazon RDS Multi-AZ DB clusters using AWS Lambda

In this post, we walk you through building an automated storage scaling solution for Amazon RDS Multi-AZ clusters with two readable standbys. We use AWS Lambda to execute scaling logic, Amazon CloudWatch to detect and alarm on storage thresholds, and Amazon SNS to deliver timely notifications. This combination provides event-driven automation, native AWS integration, and operational visibility without requiring third-party tooling.

Synchronizing a Backup on-premises Db2 Server with Amazon RDS for Db2

In this post, we provide guidance on implementing a hybrid architecture where a self-managed Db2 instance remains synchronized with Amazon RDS for Db2 via continuous archive log application, ensuring organizations maintain strategic deployment options without compromising the advantages of cloud-native managed services.

Migrate Cloud SQL for MySQL to Amazon Aurora and Amazon RDS for MySQL Using AWS DMS

In this post, we demonstrate how to migrate from Cloud SQL for MySQL 8+ to Amazon RDS for MySQL 8+ or Amazon Aurora MySQL–Compatible using AWS DMS over an AWS Site-to-Site VPN. We cover preparing the source and target environments, exemplifying cross-cloud connectivity, and setting up DMS tasks.

From bottlenecks to breakthroughs: Dutchie’s database migration journey

Dutchie, a leading technology platform serving the cannabis industry, manages critical operations for thousands of dispensaries across multiple states, processing millions of transactions annually. In this post, we explore how Dutchie successfully navigated the challenges of migrating mission-critical workloads to Amazon RDS for SQL Server in preparation for 4/20 week in 2025.

Replicate spatial data using AWS DMS and Amazon RDS for PostgreSQL

In this post, we show you how to migrate spatial (geospatial) data from self-managed PostgreSQL, Amazon RDS for PostgreSQL, or Amazon Aurora PostgreSQL-Compatible Edition to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL using AWS DMS. Spatial data is useful for applications such as mapping, routing, asset tracking, and geographic visualization. We walk through setting up your environment, configuring AWS DMS, and validating the successful migration of spatial datasets.

Upgrade legacy Amazon RDS file systems to increase storage capacity and improve performance with minimal downtime

Amazon RDS instances running on legacy file systems face several limitations. Storage is capped at 16 TiB, and some engines, including MySQL, MariaDB, and PostgreSQL, may encounter per-file size limits of approximately 2 TiB due to file system constraints, even though the database engines themselves support larger objects. In this post, I show you how to upgrade an RDS instance to the current file system with minimal downtime using Amazon RDS blue/green deployments.

Streamline Amazon RDS management with consolidation techniques – Part 2

This post is the second in a series of two dedicated to Amazon RDS consolidation. In the first post, we discussed the challenges, opportunities, and solution patterns for Amazon RDS consolidation. In this post, we introduce RDS Consolidator, a practical tool designed to optimize Amazon RDS database consolidation.

Streamline Amazon RDS management with consolidation techniques – Part 1

In this first post of a two-part series, we share proven strategies for Amazon RDS database consolidation that can help you reduce operational overhead and optimize resource utilization. In the second post, we will introduce an open source tool that we developed called RDS Consolidator, which helps you visualize your current database landscape and plan consolidation scenarios.
