The next phase of architectural modernization: Agents

In 2025, advancements in cloud technology and GenAI accelerated application modernization, but primarily benefitted greenfield projects. While AI tools boosted code generation, applying them to complex, existing (“brownfield”) applications proved challenging without sufficient architectural context, leading to technical debt and high costs. vFunction addressed this by focusing on architecture-driven modernization, delivering contextual insights directly to developers and laying the groundwork for a more autonomous, "agentic" approach in 2026 – where AI agents can confidently execute modernization tasks guided by a system's architectural intent.
