AWS AI Agents Modernize Code for Enterprises
In a world where artificial intelligence is rapidly reshaping every aspect of technology, few developments are as urgently needed—or as potentially transformative—as the modernization of legacy enterprise systems. Enter AWS, whose newly launched AI-driven application modernization service, AWS Transform, is making waves by dramatically accelerating the migration and refactoring of aging, on-premises workloads to the cloud. As of May 28, 2025, this service is now generally available, and it’s poised to redefine how businesses approach some of their most stubborn IT challenges[1][2][5].
Why Modernization Matters: The Legacy Problem
Let’s face it: most enterprises are sitting on a ticking time bomb of legacy code. According to AWS, a staggering 75% of enterprise workloads remain on-premises, with 70% of Fortune 500 companies still relying on software written over two decades ago[2][5]. These aren’t just outdated—they’re often mission-critical, sprawling across hundreds of thousands of lines of code and deeply embedded in business processes. Traditional migration projects are notorious for their complexity and duration, often dragging on for 18 months or more, and costing organizations dearly in terms of both time and talent[2].
AWS Transform: The AI-Powered Answer
AWS Transform, which initially debuted as Amazon Q Developer transformation capabilities at AWS re:Invent 2024, is designed to tackle this legacy quagmire head-on. The service leverages what AWS calls “agentic AI”—specialized artificial intelligence agents that orchestrate, analyze, and automate the migration and modernization of infrastructure, applications, and code[2][5]. These AI agents don’t just move code; they guide users through every step of the process, from analysis and planning to automated code transformation, unit test execution, and even Linux-readiness validation[5].
Sriram Devanathan, General Manager of Amazon Q Apps and AWS App Studio, put it succinctly: “The biggest challenge customers have is often understanding their code bases—not just moving them, but reimagining them.” AWS Transform is built to address this challenge by combining nearly two decades of AWS migration expertise with cutting-edge AI, effectively eliminating bottlenecks and accelerating transformation projects from years to mere months or even weeks[5].
Speed, Simplicity, and Real-World Impact
The numbers speak for themselves. AWS claims that Transform can reduce project timelines an average of fourfold compared to manual transformation. In the case of VMware migrations, the speedup can be as much as 80-fold[5]. That’s not just a marginal improvement—it’s a game-changer for enterprises desperate to modernize without disrupting their operations.
AWS Transform currently supports three primary workload types:
- Windows-based .NET applications: Facilitating migration from Windows to Linux, potentially slashing operating costs by up to 40% by eliminating Windows Server licensing fees.
- Mainframe applications: Enabling organizations to move mission-critical mainframe workloads to the cloud with unprecedented speed and simplicity.
- VMware environments: Automating the migration of complex VMware virtualized workloads, reducing both risk and manual effort[5].
Under the Hood: How Agentic AI Works
Agentic AI is more than just a buzzword here. It refers to a system where multiple specialized AI agents collaborate to perform complex tasks. In the context of AWS Transform, these agents:
- Analyze codebases: Identifying dependencies, potential issues, and optimization opportunities.
- Plan migrations: Creating detailed, step-by-step roadmaps for modernization.
- Automate refactoring: Transforming code to be cloud-native, including test execution and validation.
- Guide users: Providing real-time feedback, recommendations, and troubleshooting assistance[2][5].
This orchestrated approach not only speeds up migration but also reduces the risk of errors and ensures that modernized applications are robust, secure, and ready for the cloud.
Real-World Applications and Industry Impact
The implications for industries are profound. Take, for example, a financial institution with legacy mainframe systems that process millions of transactions daily. Migrating such systems manually would be a Herculean task, fraught with risk. With AWS Transform, the same institution can modernize its infrastructure in a fraction of the time, enabling it to leverage cloud-native features like scalability, resilience, and advanced analytics[2][5].
Similarly, enterprises running large .NET applications on Windows can migrate to Linux, not only cutting costs but also gaining access to a broader ecosystem of open-source tools and cloud services. For VMware customers, the ability to automate migration means faster time-to-value and reduced operational overhead[5].
Context and Broader Trends
AWS Transform arrives at a pivotal moment. Recent research shows that 64% of enterprises are investing in AI in 2025, and 63% are accelerating their cloud migration plans[2]. The synergy between AI and cloud migration is clear: moving mission-critical applications and data to the cloud creates a trusted foundation for AI innovation. Without modernization, enterprises risk falling behind in the race to harness AI’s full potential.
The broader tech landscape is also shifting. Synergy Research Group estimates that 37% of data center capacity remains on-premises, underscoring the scale of the modernization challenge[5]. AWS is not alone in recognizing this opportunity—competitors like Microsoft and Google are also investing heavily in AI-driven modernization tools. But AWS Transform stands out for its focus on agentic AI and its ability to handle some of the most complex, legacy-heavy workloads.
Expert Perspectives and Quotes
Sriram Devanathan’s insights are echoed by other industry leaders. “Some of these applications are really big, spanning hundreds of thousands of lines of code,” he notes. “The biggest challenge customers have is often understanding their code bases—not just moving them, but reimagining them.”[5]
AWS’s approach is also informed by its long history of enterprise migration. “We’ve spent nearly two decades leading enterprise migration and modernization, helping tens of thousands of customers transform their businesses,” the company states[2]. This experience, combined with the latest AI advancements, positions AWS Transform as a uniquely powerful solution.
