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.

Detecting fraud patterns across Snowflake and AWS using SageMaker Data Agent

Amazon SageMaker Data Agent launches three new capabilities in Amazon SageMaker Unified Studio notebooks: SQL analytics on Snowflake data sources, materialized view management, and interactive charting. Practitioners can use them together to query Snowflake alongside AWS data, pre-compute and schedule repeated aggregations, and create interactive visualizations from natural language prompts in a single notebook, without writing boilerplate code or switching tools. In this post, we describe the challenges these capabilities address, introduce each one, and walk through a fraud analytics scenario that demonstrates them working together in an end-to-end investigation workflow.

Introducing Private Networking for Amazon MQ for RabbitMQ

In this post, we explain how Private Networking for Amazon MQ for RabbitMQ works and walk through the setup process. Whether you’re securing a private identity provider, federating messages between brokers, or connecting to self-hosted RabbitMQ, your broker can now reach private destinations without exposing them publicly.

AI-assisted data development with Kiro and SageMaker Unified Studio

With the AWS Toolkit for Visual Studio Code, you can connect Kiro, VS Code, or Cursor directly to Amazon SageMaker Unified Studio. This post demonstrates the integration using Kiro. The same Remote Access connection works with VS Code and Cursor. The post starts by showing what you can do with this integration: using natural language to explore and analyze data in a governed environment. We then walk through the setup so you can try it yourself.

Modernize Amazon Redshift: RA3 to RG Migration best practices

In this post, you learn how to migrate Amazon Redshift RA3 clusters to Graviton-based RG instances. We compare the Elastic Resize, Classic Resize, and Snapshot/Restore migration strategies, with key considerations and best practices to support a smooth migration. We also provide mapping guidance from RA3 to RG to help you right-size your cluster.

Access Amazon S3 data files directly using AWS Lake Formation permissions

In this post, we demonstrate reading from and writing to Lake Formation-managed S3 locations using Apache Spark jobs from EMR. Lake Formation credential vending for S3 location access is available in EMR release label 7.13 and later, Boto3 1.42.29 and later, AWS Java SDK 2.41.32 and later, and AWS Command Line Interface (AWS CLI) version 2.33.1 and later.

Building AI shopping agent using Amazon Bedrock AgentCore Runtime and Amazon OpenSearch Service

In this post, we explore how to build an online shopping AI agent. We focus on its architecture and implementation with Amazon OpenSearch Service, Amazon Bedrock AgentCore, and Strands Agents. Amazon Bedrock AgentCore is an agentic platform for deploying and operating those agents and tools securely at scale without managing infrastructure.

Choosing the right workflow orchestration service for your use case: Amazon MWAA and AWS Step Functions

This post explores how to select the right workflow orchestration service based on your specific use case requirements. We’ll examine key workflow characteristics, present real-world scenarios, and provide practical guidance to help you make an informed decision for your particular needs.

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).
