Today, we are excited to announce the availability of Prompt Optimization on Amazon Bedrock. With this capability, you can now optimize your prompts for several use cases with a single API call or a click of a button on the Amazon Bedrock console. In this blog post, we discuss how Prompt Optimization improves the performance of large language models (LLMs) for intelligent text processing task in Yuewen Group.

AWS introduces new EC2 instance families (C8gd, M8gd, R8gd) powered by Graviton4 processors with NVMe SSD storage, offering up to 30% better performance, 3x more vCPUs and memory, and up to 11.4TB local storage compared to Graviton3-based predecessors.

Many organizations validate their generative AI–based workloads on their emotional reaction to a foundation model’s output instead of real testing criteria. In this post, we show you how you can move away from vibe testing and effectively evaluate your Amazon Bedrock workloads for production.

This post explores the importance of distributed tracing for operating serverless applications and announces an important update to tracing behavior for AWS Lambda, which streamlines how trace context is handled in PassThrough mode. This blog post will demonstrate how this change gives you better control over how your Lambda functions handle tracing with AWS X-Ray through practical examples. Whether you’re building new applications or operating existing ones, this update helps you achieve more predictable and efficient tracing across your serverless applications built using Lambda.

In this post, we present a practical approach to one of the most significant challenges organizations face when adopting Amazon RDS Custom for SQL Server: migrating large datasets from SQL Server on Amazon EC2 to Amazon RDS Custom for SQL Server efficiently and cost-effectively. By using SQL Server’s native detach and attach method combined with EBS snapshots, you can migrate your databases without requiring Amazon S3 or AWS DMS.

When getting started with DynamoDB, one of the first decisions you will make is choosing between two throughput modes: on-demand and provisioned. On-demand mode is the default and recommended throughput option because it simplifies building modern, serverless applications that can start small and scale to millions of requests per second. However, choosing the right throughput strategy requires evaluating your operational needs, development velocity, and application characteristics, with cost being a key consideration. In this post, we examine both throughput modes in detail, exploring their characteristics, strengths, and ideal use cases.

When you decide to upgrade your PostgreSQL database which is configured as source or target for an ongoing AWS DMS task, it’s important to factor this into your upgrade planning.
