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.

Organizations running SQL Server workloads on Amazon RDS sometimes need to migrate their databases to different AWS accounts. This migration becomes more complex when mission-critical data requires column-level encryption to meet compliance requirements. In this post, we demonstrate how you can migrate your symmetric key-encrypted database on Amazon RDS for SQL Server to another AWS account without compromising security. The solution we present can also help you implement symmetric key encryption on a new database in Amazon RDS for SQL Server.

In this post, we provide the steps to migrate a PostgreSQL database from Google Cloud SQL to RDS for PostgreSQL and Aurora PostgreSQL using the pglogical extension. We also demonstrate the necessary connection attributes required to support the database migration. The pglogical extension works for the community PostgreSQL version 9.4 and higher, and is supported on RDS for PostgreSQL and Aurora PostgreSQL as of version 12+.

Organizations are increasingly seeking to modernize their database infrastructure by migrating from legacy database engines such as Microsoft SQL Server and Oracle to more cost-effective and scalable open source alternatives such as PostgreSQL. This transition not only reduces licensing costs but also unlocks the flexibility and innovation offered by PostgreSQL’s rich feature set. In this post, we demonstrate how to convert and test database code from Microsoft SQL Server and Oracle to PostgreSQL using the generative AI capabilities of Amazon Bedrock.

In this post, we guide you through setting up automation for pre-upgrade checks and upgrading a fleet of Amazon RDS for PostgreSQL instances. In this solution, we use AWS Systems Manager to automate the Amazon RDS upgrade job.

In this post, we demonstrate how to configure a linked server between Amazon RDS for SQL Server and a Teradata database instance. We guide you through the step-by-step process to establish this connection and show you how to verify its functionality.

Text-to-SQL can automatically transform analytical questions into executable SQL code for enhanced data accessibility and streamlined data exploration, from analyzing sales data and monitoring performance metrics to assessing customer feedback. In this post, we explore how to use Amazon Relational Database Service (Amazon RDS) for PostgreSQL and Amazon Bedrock to build a generative AI text-to-SQL chatbot application using Retrieval Augmented Generation (RAG). We’ll also see how we can use Amazon MemoryDB with vector search to provide semantic caching to further accelerate this solution.

pgTAP (PostgreSQL Test Anything Protocol) is a unit testing framework that empowers developers to write and run tests directly within the database. In this post, we explore how to leverage the pgTAP extension for unit testing on Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition database, helping you build robust and reliable database applications.

Careem powers rides, deliveries, and payments across the Middle East, North Africa and South Asia. As Careem grew, so did its data infrastructure challenges. Their monolithic 270 TB Amazon RDS for MySQL database consisting of one writer and five read replicas— experienced performance issues due to increased storage utilization, slow queries, high replica lag, and increased Amazon RDS cost. In this post, we provide a step-by-step breakdown of how Careem successfully implemented a phased data purging strategy, improving DB performance while addressing key technical challenges.

In this post, we show how you can use Amazon CloudWatch Database Insights for troubleshooting your Amazon RDS and Amazon Aurora resources. CloudWatch Database Insights serves as a database observability solution offering a tailored experience for DevOps engineers, application developers, and database administrators. This tool is designed to accelerate database troubleshooting processes and address issues across entire database fleets, enhancing overall operational efficiency.
