Architecting for AI excellence: AWS launches three Well-Architected Lenses at re:Invent 2025
At re:Invent 2025, we introduce one new lens and two significant updates to the AWS Well-Architected Lenses specifically focused on AI workloads: the Responsible AI Lens, the Machine Learning (ML) Lens, and the Generative AI Lens. Together, these lenses provide comprehensive guidance for organizations at different stages of their AI journey, whether you’re just starting to experiment with machine learning or already deploying complex AI applications at scale.
Announcing the updated AWS Well-Architected Generative AI Lens
We are delighted to announce an update to the AWS Well-Architected Generative AI Lens. This update features several new sections of the Well-Architected Generative AI Lens, including new best practices, advanced scenario guidance, and improved preambles on responsible AI, data architecture, and agentic workflows.
Announcing the updated AWS Well-Architected Machine Learning Lens
We are excited to announce the updated AWS Well-Architected Machine Learning Lens, now enhanced with the latest capabilities and best practices for building machine learning (ML) workloads on AWS.
Know before you go – AWS re:Invent 2025 guide to Well-Architected and Cloud Optimization sessions
Are you ready to maximize your Well-Architected and Cloud Optimization learning and networking time at re:Invent 2025? We have put together this comprehensive guide to help you plan your schedule and make the most of the Well-Architected and cloud optimization sessions available this year. These sessions will deliver the practical guidance your teams need to lead strategic cloud initiatives, design next-generation architectures, optimize costs, or secure AI-powered systems.
Build resilient generative AI agents
Generative AI agents in production environments demand resilience strategies that go beyond traditional software patterns. AI agents make autonomous decisions, consume substantial computational resources, and interact with external systems in unpredictable ways. These characteristics create failure modes that conventional resilience approaches might not address. This post presents a framework for AI agent resilience risk analysis […]
Maximizing Business Value Through Strategic Cloud Optimization
As cloud spending continues to surge, organizations must focus on strategic cloud optimization to maximize business value. This blog post explores key insights from MIT Technology Review’s publication on cloud optimization, highlighting the importance of viewing optimization as a continuous process that encompasses all six AWS Well-Architected pillars.
Empower your teams with modern architecture governance
Modern cloud architectures demand a new governance approach. In this post, we show how collaborative architecture oversight can transform team performance through automation, self-service platforms, and distributed decision-making.
Announcing the AWS Well-Architected Generative AI Lens
We are delighted to introduce the new AWS Well-Architected Generative AI Lens. Use the lens to make sure that your generative AI workloads are architected with operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability in mind.
Build and operate an effective architecture review board
In this post, we identify the components of an efficient architecture review process, define what an ARB is, and describe how to build and operate an effective enterprise ARB.
Announcing the Well-Architected Data Residency with Hybrid Cloud Services Lens
The new Well-Architected Data Residency with Hybrid Cloud Services Lens is available now. Use the lens whitepaper to adopt your hybrid cloud workloads according to the tenants of the Well-Architected Framework while maintaining data sovereignty requirements.
