本文介绍了AWS近期发布的一系列新服务和更新，重点关注了Strands Agents SDK，这是一个用于构建和运行AI Agent的开源工具。此外，文章还概述了.NET应用现代化、Mainframe和VMware工作负载现代化、Amazon Bedrock Guardrails、VPC CloudTrail日志记录、EC2实例ENA队列分配、EC2 P6-B200实例、AWS Control Tower报告以及AWS AppSync事件集成等方面的更新。

🚀Strands Agents SDK：这是一个开源的SDK，只需几行代码即可构建和运行AI Agent。它支持多种模型提供商，包括Amazon Bedrock、Ollama等，并允许使用Python函数作为工具。AWS的多个团队已经在生产中使用Strands Agents，例如Amazon Q Developer和AWS Glue。

🛠️AWS Transform for .NET：新增功能支持使用私有NuGet包的项目，将MVC Razor视图移植到ASP .NET Core Razor视图，并运行移植的单元测试，加速.NET应用程序的现代化。

☁️Mainframe和VMware工作负载现代化：AWS Transform 自动化评估、规划和转换Mainframe和VMware工作负载，简化了向云架构的迁移过程。

🛡️Amazon Bedrock Guardrails：现在支持跨区域推理，为调用任何模型（包括Amazon Bedrock、自托管模型和第三方模型）提供可配置的安全防护，帮助标准化安全和隐私控制。

⚡EC2 P6-B200实例：搭载NVIDIA Blackwell GPU，加速AI创新，特别适用于大规模分布式AI训练和推理，以及高性能计算应用。

<section class="blog-post-content lb-rtxt"><table><tbody><tr><td><p></p></td></tr></tbody></table><p>Many events are taking place in this period! Last week I was at the <a href="https://www.aiweek.it/en/&quot;&gt;AI Week</a> in Italy. This week I’ll be in Zurich for the <a href="https://www.awsug.ch/&quot;&gt;AWS Community Day – Switzerland</a>. On May 22, you can join us remotely for <a href="https://aws-experience.com/amer/smb/e/97e5d/aws-cloud-infrastructure-day?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;AWS Cloud Infrastructure Day</a> to learn about cutting-edge advances across compute, AI/ML, storage, networking, serverless technologies, and global infrastructure. Look for events near you for an opportunity to share your knowledge and learn from others.</p><p>What got me particularly excited last Friday was the introduction of <a href="https://strandsagents.com/&quot;&gt;Strands Agents</a>, an open source SDK that you can use to build and run AI agents in just a few lines of code. It can scale from simple to complex use cases, including local development and production deployment. By default, it uses <a href="https://aws.amazon.com/bedrock/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Amazon Bedrock</a> as model provider, but many others are supported, including Ollama (to run models locally), Anthropic, Llama API, and LiteLLM (to provide a unified interface for other providers such as Mistral). With Strands, you can use any Python function as a tool for your agent with the <code>@tool</code> decorator. Strands provides many example tools for manipulating files, making API requests, and interacting with AWS APIs. You can also choose from thousands of published <a href="https://modelcontextprotocol.io/examples&quot;&gt;Model Context Protocol (MCP)</a> servers, including <a href="https://github.com/awslabs/mcp&quot;&gt;this suite of specialized MCP servers that help you get the most out of AWS</a>. Multiple teams at AWS already use Strands for their AI agents in production, including <a href="https://aws.amazon.com/q/developer/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Amazon Q Developer</a>, <a href="https://aws.amazon.com/glue/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;AWS Glue</a>, and <a href="https://docs.aws.amazon.com/vpc/latest/reachability/what-is-reachability-analyzer.html?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;VPC Reachability Analyzer</a>. <a href="https://aws.amazon.com/blogs/opensource/introducing-strands-agents-an-open-source-ai-agents-sdk/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Read it all in Clare’s post</a>.</p><p><a href="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/05/19/agentic-loop-1.png&quot;&gt;&lt;img class="aligncenter size-full wp-image-96334" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/05/19/agentic-loop-1.png&quot; alt="Strands Agents SDK agentic loop" width="1118" height="555" /></a></p><p><strong>Last week’s launches</strong><br />Here are the other launches that got my attention:</p><ul><li><a href="https://aws.amazon.com/blogs/aws/aws-transform-for-net-the-first-agentic-ai-service-for-modernizing-net-applications-at-scale/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;AWS Transform for .NET, the first agentic AI service for modernizing .NET applications at scale</a> – Compared to the preview, we added new capabilities to support projects with private NuGet packages, porting model-view-controller (MVC) Razor views to ASP .NET Core Razor views, and running the ported unit tests.</li><li><a href="https://aws.amazon.com/blogs/aws/accelerate-the-modernization-of-mainframe-and-vmware-workloads-with-aws-transform/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Accelerate the modernization of Mainframe and VMware workloads with AWS Transform</a> – To automate assessment, planning, and transformation of both mainframe and VMware workloads into cloud-based architectures, streamlining the entire process.</li><li><a href="https://aws.amazon.com/about-aws/whats-new/2025/05/amazon-bedrock-guardrails-cross-region-inference/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Amazon Bedrock Guardrails now supports cross-Region inference</a> – <a href="https://aws.amazon.com/bedrock/guardrails/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Amazon Bedrock Guardrails</a> provides configurable safeguards when invoking any model including those hosted in <a href="https://aws.amazon.com/bedrock/?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;Amazon Bedrock</a>, self-hosted models, and third-party models outside Bedrock using the <a href="https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-use-independent-api.html?trk=e61dee65-4ce8-4738-84db-75305c9cd4fe&amp;amp;sc_channel=el&quot;&gt;ApplyGuardrail API</a>, providing a consistent experience to help standardize safety and privacy controls.
