AWS seeks to automate cloud optimization with new AI agent

AWS is applying AI to the challenge of evaluating and improving cloud environments with a public preview of a new agentic service aimed at automating the discovery and optimization of architectural issues.

Despite its name, AWS makes no claims for the architectural qualities of its Well-Architected Agent, the name of which refers to a long line of frameworks and tools for cloud architecture management dating back over a decade. AWS launched the first, the Well-Architected Framework, in 2015, later introducing the Well-Architected Tool in 2018 to help customers review their own workloads against the framework’s best practices.

In contrast to the Tool’s reliance on enterprise teams to provide information about their workloads through a structured set of questions, the Agent analyzes the AWS environment itself and uses that information to generate recommendations, the company wrote in a blog post.

Enterprises can also give the agent business objectives and application context to enable it to rank its findings against those goals, AWS said.

The Agent surfaces recommendations at three levels: individual resources, applications, and overall architecture, suggesting remediation steps and identifying their potential cost impact.

Those remediation steps can include environment-specific implementation guidance such as console walkthroughs, AWS CLI commands, and updated infrastructure-as-code changes, AWS said, while the existing Tool merely proposes an improvement plan.

Optimizing cloud optimization

For enterprise users, particularly cloud architects, DevOps teams, and platform engineers, the new agent can speed up optimization and change the way they manage cloud environments, moving from periodic architecture reviews and reactive remediation toward more continuous, AI-assisted optimization, said Siddharth Mehta, research leader at consulting and services company Avasant.

That shift in how cloud environments are managed will become increasingly relevant as enterprises scale agentic applications, according to Nhat Bui, deputy director of engineering at Scopic Software. 

“First, AI applications change faster and have less predictable cost profiles than traditional workloads, so a review done last quarter goes stale quickly. Second, more infrastructure is now being written by AI coding tools, and human reviewers can’t keep pace with that volume,” Bui said.

There are limits to the agent’s ability to offer timely recommendations, though: “The Agent refreshes resource-and application-level recommendations weekly, while architecture-level recommendations are generated through on-demand reviews,” Bui said. That distinction could be particularly important for fast-changing workloads, including agentic applications, where infrastructure and resource usage can change between recommendation refreshes, he added.

That said, the new agent could help accelerate the pace of cloud-related decision-making, said Pareekh Jain, principal analyst at Pareekh Consulting. “Instead of giving CIOs hundreds of technical recommendations, the agent can help identify which improvements matter most to the business. That means CIOs can decide where to prioritize cloud investments and engineering resources, and where to accept trade-offs,” he said.

Limitations of the new Agent

However, the Well-Architected Agent has its own set of limitations, said Mehta. “The Agent only understands the context available to it. It may not know about regulatory obligations, third-party dependencies, business-process dependencies, contractual SLAs, internal risk appetite, multi-cloud dependencies, and organizational policies not represented in AWS,” he said. “Therefore, business-goal alignment improves prioritization but does not replace enterprise architecture or risk governance.”

For Jain, however, the bigger limitation is the Agent’s requirement for a high-tier AWS Support plan, which could limit its adoption among enterprises that do not already subscribe to those plans.

The Agent is available only to customers on AWS Business+, Enterprise On-Ramp, Enterprise Support, or Unified Operations plans, unlike the Well-Architected Tool, which does not require a paid Support plan, he said.

Moreover, Mehta said, the Agent is narrower in scope, currently covering cost, security, performance, and resilience, while the Well-Architected Tool continues to support all six pillars of the Well-Architected framework, including operational excellence and sustainability.

There is no specific additional fee for the Agent or the Tool, although enterprises are charged for some of the underlying AWS resources, services, and data that they consume, including those from Trusted Advisor, Compute Optimizer, Security Hub CSPM, Resilience Hub, Cost Optimization Hub, and Cost Explorer.
