AWS has opened a public preview of Well-Architected Agent. The eligibility rule to use is in the user guide, not the looser line in the announcement.
Who can open it
The guide limits the agent to an AWS Support plan at the Business+ tier or higher: Business+, Enterprise On-Ramp, Enterprise Support, or Unified Operations. Customers on Developer or Business tier plans do not have access. The AWS News Blog says the agent is delivered by AWS Support and available to customers with an AWS Support plan. That sentence does not name the cutoff. The guide does.
Profiles are hosted in US East (N. Virginia), US East (Ohio), or US West (Oregon). From those hosting Regions the agent scans resources in all commercial AWS Regions, and the blog says you can onboard workloads from any AWS commercial Region. A single profile can analyze up to 100 AWS accounts.
What the preview returns
Well-Architected Agent is an AI-powered optimization service, in preview and subject to change. It analyzes an AWS environment and delivers prioritized recommendations across cost, security, performance, and resilience. The guide says it is intended for both business leadership and technical teams. By tying recommendations to stated business goals, it helps leadership and engineering teams align on technical remediation priorities derived from business objectives.
Unlike a point-in-time architecture review, the agent analyzes on an ongoing schedule. Scheduled recommendations refresh weekly. You create a profile that defines accounts, Regions, optimization pillars, and goals. The agent scans the configured accounts and generates recommendations at three levels: resource, application, and architecture. Application-level recommendations are a new format and are currently in beta. The guide says to review each one thoroughly before acting, and says AWS is seeking feedback on their quality and relevance.
The news blog describes the analysis underneath those levels. The agent correlates utilization metrics, resource configurations, and application topology, and checks them against Well-Architected best practices across 65+ AWS services. You declare business objectives and application context. It prioritizes recommendations by impact and effort against those goals, and it surfaces cross-pillar trade-offs. Resource findings can include a specific dollar impact where applicable, with step-by-step remediation. Application findings consolidate issues across resources in that scope. Architecture findings can include the Infrastructure as Code changes needed to align with best practices. The guide adds that every recommendation shows positive impact on the other pillars, plus a trade-off that names the pillar, risk level, and a mitigation strategy. The agent also ingests findings from services such as AWS Trusted Advisor, then adds personalization, goal ranking, and automation-ready remediation.
You pick the remediation path. The blog lists console walk-throughs, updated IaC for architecture-level recommendations, and AWS CLI commands. For a pre-deployment review, you can upload a zip of a Terraform, CloudFormation, or CDK project and select a Well-Architected lens. When you choose an updated IaC template, the agent provides code changes you can copy into an existing template. Recommendations are also available through the console and the wellarchitected API. The blog points to the AWS MCP Server and plugins if you want to pull that into an AI coding tool. Generative output may contain errors or incomplete information. You are responsible for evaluating each recommendation and for oversight and safeguards.
In the Well-Architected console, you create an agent profile and provision customer-managed IAM roles the agent uses to read resource configurations, utilization metrics, and application topology. The blog says resource and application recommendations are generated within 24 hours after profile creation. Scheduled recommendations then refresh weekly.
You can still use the AWS Well-Architected Tool to manually evaluate your cloud architecture with user-defined lenses that measure your workload using your own best practices.
If your plan is Business+ or higher, open the Well-Architected console, create one agent profile, and review recommendations before you apply a change. Application-level recommendations are in beta and should be reviewed thoroughly. Generative output more broadly may be wrong or incomplete. If you are on Developer or Business support, stop at the user guide's availability section. Those tiers do not have access.
