The zero-ETL integrations for Amazon Redshift are designed to automate data movement into Amazon Redshift, eliminating the need for traditional ETL pipelines. With zero-ETL integrations, you can reduce operational overhead, lower costs, and accelerate your data-driven initiatives. This enables organizations to focus more on deriving actionable insights and less on managing the complexities of data integration. In this post, we discuss the best practices for migrating your ETL pipeline from AWS DMS to zero-ETL integrations for Amazon Redshift.

Amazon DynamoDB Accelerator (DAX) is a fully managed, in-memory cache for DynamoDB. By using DAX with DynamoDB, you can improve the latency for read requests in your application. In this post, we discuss how to improve latency and reduce cost when using DynamoDB for your read-heavy applications.

In this post we demonstrate, how you can extend your existing AD infrastructure and Kerberos authentication to Amazon RDS for Db2.

With Amazon RDS for Db2, you can seamlessly authenticate your users and groups with or without Kerberos authentication using a single AWS Microsoft AD directory that can serve multiple accounts. In this post, we use AWS Managed Microsoft AD from an AWS account to provide Microsoft AD authentication to Amazon RDS for Db2 in a different account.

This is the first post of a series dedicated to table restores and data integrity. In this post, we present a solution that automates the PITR restoration process and handles data changes that occur during the restoration, providing a fluid transition back to the restored DynamoDB table with near-zero downtime. This solution enables you to restore a DynamoDB table efficiently with minimum impact your application.

In this post, we look at two capabilities in Amazon Bedrock Knowledge Bases that make it easier to build RAG workflows with Amazon Aurora Serverless v2 as the vector store. The first capability helps you easily create an Aurora Serverless v2 knowledge base to use with Amazon Bedrock and the second capability enables you to automate deploying your RAG workflow across environments.

In this post, we introduce postgres_get_av_diag(), a new function available in RDS for PostgreSQL to monitor aggressive autovacuum blockers. By using this function, you can identify and address performance and availability risks through actionable insights provided by postgres_get_av_diag().
