Today we are excited to announce version 1.0 of the Strands Agents SDK, marking a significant milestone in our journey to make building AI agents simple, reliable, and production-ready. Strands Agents is an open source SDK that takes a model-driven approach to building and running AI agents in just a few lines of code. Strands […]

Developers are architecting and building systems of AI agents that work together to autonomously accomplish users’ tasks. In Part 1 of our blog series on Open Protocols for Agent Interoperability we covered how Model Context Protocol (MCP) can be used to facilitate inter-agent communication and the MCP specification enhancements AWS is working on to enable […]

In Part 1 of our blog series on Open Protocols for Agent Interoperability we covered how the Model Context Protocol (MCP) can be used to facilitate inter-agent communication and the MCP specification enhancements AWS is working on to enable that. In Part 2 of this blog series we dive deep into authentication in the latest […]

We are excited to announce our new community meetings series for the AWS Cloud Development Kit (CDK) project. These meetings are designed to give everyone from seasoned contributors to new users a recurring opportunity to learn, ask questions, and share feedback directly with the AWS CDK team. We also see this as a great opportunity […]

Today, the open source Cedar project announced the release of authorization-for-expressjs, an open source package that simplifies using the Cedar policy language and authorization engine to verify application permissions. This release allows developers to add policy-based authorization to their Express web framework APIs within minutes, and without any remote service calls. Express is a minimal […]

Today, we’re excited to announce Cedar Analysis, a new open source toolkit for developers that makes it easier for everyone to verify the behavior of their Cedar policies. Cedar is an open source authorization system that enables developers to implement fine-grained access controls in their applications. With ~1.17 million downloads and growing adoption, Cedar is […]

When we introduced the Strands Agents SDK, our goal was to make agentic development simple and flexible by embracing a model-driven approach. Today, we’re excited to highlight how you can use Claude 4’s interleaved thinking beta feature with Strands to further simplify how you write AI agents to solve complex tasks with tools. With a […]

This post was contributed by Andrea Veri from the GNOME Foundation. It has been cross-posted from gnome.org with permission. GNOME has historically hosted its infrastructure on premises. That changed with an AWS Open Source Credits program sponsorship which has allowed our team of two SREs to migrate the majority of the workloads to the cloud […]

Microservices and containers are revolutionizing how modern applications are built, deployed, and managed in the cloud. However, developing and operating microservices can introduce significant complexity, often requiring developers to spend valuable time on cross-cutting concerns like service discovery, state management, and observability. Dapr (Distributed Application Runtime) is an open source runtime for building microservices on […]

At AWS, open standards run deep in our DNA, driving all that we do. That’s why we decided to build Amazon Elastic Cloud Compute (EC2) as a protocol-agnostic cloud computing service and Amazon SageMaker as a framework-agnostic deep learning service. Our commitment to openness continues as we enter the agentic AI era, extending to inter-agent […]
