Migrating from SQL Server to Amazon Aurora can significantly reduce database licensing costs and modernize your data infrastructure. To accelerate your migration journey, we have developed a migration solution that offers ease and flexibility. You can use this migration accelerator to achieve fast data migration and minimum downtime while customizing it to meet your specific business requirements. In this post, we showcase the core features of the migration accelerator, demonstrated through a complex use case of consolidating 32 SQL Server databases into a single Amazon Aurora instance with near-zero downtime, while addressing technical debt through refactoring.

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.

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.

In this post, we provide a comprehensive, step-by-step guide for migrating an on-premises self-managed encrypted MySQL database to Amazon Aurora MySQL using AWS DMS homogeneous data migrations over a private network. We show a complete end-to-end example of setting up and executing an AWS DMS homogeneous migration, consolidating all necessary configuration steps and best practices.

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.

Amazon Aurora PostgreSQL-Compatible Edition supports managed blue/green deployments to help reduce downtime and minimize risk during updates. Even with thorough planning and testing in non-production environments, unexpected issues can emerge after a version upgrade. In these cases, having a rollback plan is essential to quickly restore service stability. While the managed Blue/Green deployment feature doesn’t currently include built-in rollback functionality, you can implement alternative solutions for version management. In this post, we show how you can manually set up a rollback cluster using self-managed logical replication to maintain synchronization with the newer version after an Amazon RDS Blue/Green deployment switchover.

In this post, we explore how a leading AWS customer in the learning services industry successfully modernized its legacy SAP ASE environment by migrating to Amazon Aurora PostgreSQL-Compatible Edition. Partnering with AWS, the customer engineered a comprehensive migration strategy to transition from a proprietary system to an open source database while providing high availability, performance optimization, and cost-efficiency.

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.

Connecting to an Amazon RDS for Db2 instance has traditionally required spinning up an Amazon EC2 bastion host or running Db2 clients locally. With the new AWS CloudShell VPC integrated environments, you can now securely connect—with no Amazon EC2 required, no local installs, and no cost beyond normal Amazon RDS and AWS networking. In this post, we show you how to connect to Amazon RDS for Db2 using CloudShell.
