Amazon Strands Agents SDK: A technical deep dive into agent architectures and observability

The Amazon Strands Agents SDK is an open source framework for building AI agents that emphasizes a model-driven approach. Instead of hardcoding complex task flows, Strands uses the reasoning abilities of modern large language models (LLMs) to handle planning and tool usage autonomously. Developers can create an agent with a prompt (defining the agent’s role or behavior) and a list of tools, and the LLM-powered agent will figure out how to chain its reasoning and invoke tools as needed. This dramatically simplifies agent development compared to traditional workflow-based frameworks.

In this post, we first introduce the Strands Agents SDK and its core features. Then we explore how it integrates with AWS environments for secure, scalable deployments, and how it provides rich observability for production use. Finally, we discuss practical use cases, and present a step-by-step example to illustrate Strands in action.
