In this post, we demonstrate how to configure a standby replica for your RDS for Db2 instance. We also discuss best practices for setting up, monitoring, and managing standby replicas.

AWS Backup supports the creation of on-demand backups of RDS Custom for SQL Server instances. However, the restoration of RDS Custom for SQL Server instances through AWS Backup is not natively supported at the time of writing this post. Nonetheless, this post presents a workaround solution that enables the successful restoration of RDS Custom for SQL Server instances using AWS Backup-created backups.

Generative AI solutions are transforming how businesses operate worldwide. It has now become paramount for businesses to integrate generative AI capabilities into their customer-facing services and applications. The challenge they often face is the need to use massive amounts of relational data hosted on SQL Server databases to contextualize these new generative AI solutions. In this post, we demonstrate how you can address this challenge by combining Amazon RDS for SQL Server and Amazon SageMaker Lakehouse.

In November 2024, AWS introduced the latest evolution of its custom-designed ARM-based processors with Graviton4, delivering significant performance and efficiency improvements for Amazon RDS for PostgreSQL, MySQL, and MariaDB and Amazon Aurora. In this post, we focus on Amazon RDS for PostgreSQL and compare the performance of the new Graviton4 instances to both Graviton3 and Graviton2. Using benchmarks, we evaluate throughput, latency, and price-performance, showcasing the advantages of Graviton4 for modern database workloads.

In today’s employment landscape, job search platforms play a crucial role in connecting employers with potential candidates. Behind these platforms lie complex search engines that must process and analyze vast amounts of structured and unstructured data to deliver relevant results. This post explores how to use PostgreSQL’s search features to build an effective job search engine. We examine each search capability in detail, discuss how they can be combined in PostgreSQL, and offer strategies for optimizing performance as your search engine scales.

As your business grows and your databases expand into the terabyte range, optimizing your backup strategy becomes increasingly important for maintaining operational excellence. Modern backup solutions that implement incremental backups where possible, offer an elegant way to protect your valuable data while minimizing maintenance windows and ensuring consistent application performance. In this post, we discuss the aspects of maximizing the use of incremental backups in Amazon RDS, leading to backup times remaining steady even while the database grows.

Amazon RDS provides two storage types: Provisioned IOPS SSD and General Purpose SSD. They differ in performance characteristics and price, which means that you can tailor your storage performance and cost to the needs of your database workload. In this post, we show how you can migrate from io1 to io2 Block Express Provisioned IOPS SSD storage.

For encrypting data at rest, Amazon RDS for Oracle offers two choices: AWS KMS and Oracle TDE. Although both AWS KMS and Oracle TDE provide encryption at rest capabilities, there are various factors to consider when choosing between them, such as licensing, edition dependency, encryption granularity, and feature restrictions. In this post, we provide guidance on choosing between the AWS KMS and Oracle TDE options for encrypting data at rest in RDS for Oracle, focusing on these key aspects.

In this post, we explore SQL Server replication implementation on Amazon RDS Custom. You’ll learn about different replication types supported on RDS Custom SQL Server, including snapshot, transactional, and merge replication, along with their specific use cases. Finally, we provide a step-by-step guide to setting up replication, from configuring the distributor to creating publications and managing subscriptions.

Row-level security (RLS) is a security mechanism that enhances data protection in scalable applications by controlling access at the individual row level. It enables organizations to implement fine-grained access controls based on user attributes, so users can only view and modify data they’re authorized to access. This post focuses on implementing a cost-effective custom RLS solution using native MySQL features, making it suitable for a wide range of use cases without requiring additional software dependencies. This solution is applicable for both Amazon Relational Database Service (Amazon RDS) for MySQL and Amazon Aurora MySQL-Compatible Edition, providing flexibility for users of either service.
