How Autodesk migrated 2.3 billion documents to Amazon OpenSearch Service using Migration Assistant and intelligent routing

This post walks through how Autodesk re-architected a single-index Elasticsearch 7.1.1 domain on Amazon OpenSearch Service into four multi-index OpenSearch Service domains, using Migration Assistant for Amazon OpenSearch Service and a routing layer that directs each query to the shards that hold the data for that query.

Build a contract compliance search system with Amazon OpenSearch

In this post, you build a contract compliance search system that combines semantic search with semantic highlighting in Amazon OpenSearch Service. You deploy the solution using two AWS CloudFormation stacks, test it with synthetic contract documents, and see how a single query surfaces both the right contracts and the right clauses within them.

Alight OpenSearch Service architecture showing cross-account log ingestion from Amazon ECS and Amazon EC2 workloads through OpenSearch Ingestion to Amazon OpenSearch Service

How Alight Solutions achieved 55% cost savings with Amazon OpenSearch Service

In this post, we share how Alight Solutions migrated from self-managed Elasticsearch to Amazon OpenSearch Service. The migration achieved a 55% cost reduction, alleviated approximately 2,000 hours per year of operational overhead, and gave Alight access to advanced observability features they could not prioritize before.

Patch perfect: Automating Amazon Redshift patch testing

In this post, we demonstrate an automated test suite that validates your Amazon Redshift cluster automatically after any patch, reboot, or modification. It uses standard drivers against real workload patterns to provide a verified gate between a patch landing and that patch reaching production.

Deploy modern data platforms in minutes with MDAA

In this post, we explore how MDAA transforms data architecture development from months of manual coding to production-ready deployment through configuration-driven infrastructure and embedded governance, examine a real customer transformation, and provide a clear implementation pathway for your own data modernization journey.

Why tombola chose Graviton-powered RG instances for Amazon Redshift

In this post, you learn how tombola followed a strict engineering principle: no changes to production without evidence. That meant a head-to-head comparison of RA3 versus RG on their actual workload. You also see benchmark results on Amazon S3 Tables and the migration from RA3 to RG instances.

Real-time CDC from Aurora PostgreSQL to Amazon S3 Tables using Debezium and Firehose

In this post, we show you how to build a CDC pipeline that delivers query-ready Iceberg tables directly. The pipeline captures inserts, updates, and deletes from Aurora PostgreSQL and applies them as row-level operations in Amazon S3 Tables, a capability of Amazon Simple Storage Service (Amazon S3).

Meet Amazon Redshift RG – AWS Graviton-based instances with an integrated data lake query engine delivering up to 2.4x better performance at 30% lower price than RA3

On May 12, 2026, we announced the general availability of Amazon Redshift RG instances, powered by AWS Graviton processors. RG instances are up to 2.2x as fast for data warehouse workloads and up to 2.4x as fast for data lake workloads, all at 30% lower price per vCPU compared to RA3 instances. RG instances support all data lake formats supported by RA3 and eliminate Amazon Redshift Spectrum’s per-TB scanning charges. RG instances feature a custom-built integrated vectorized query engine, making them a more performant and cost-effective foundation for unified analytics. We are launching with two instance sizes: rg.xlarge and rg.4xlarge, with additional sizes coming later this year.

How to set up a network-isolated VPC for Amazon SageMaker Unified Studio

In this post, we explore scenarios where customers need more control over their network infrastructure when building their unified data and analytics strategic layer. We’ll show how you can bring your own Amazon Virtual Private Cloud (Amazon VPC) and set up Amazon SageMaker Unified Studio for strict network control.
