Unlocking enterprise agility with AI-Powered Mainframe Modernization
Mainframes have long been central to enterprise operations, yet they can quickly become a barrier to growth and agility. The conversation has now shifted from whether to modernize to how to modernize effectively while elevating experiences, driving innovation and resilience.
HCLTech is transforming mainframes from rigid, siloed systems into adaptive platforms that power business innovation. The result? Faster programs, smarter operations and future-ready applications keep enterprises ahead of the curve.
Transforming the Core: A Blueprint for AI-powered Mainframe Modernization
The strong momentum in modernization investments shows that organizations are no longer content with incremental optimization—they see modernization as essential to staying competitive, resilient and agile in a digital-first world. By using GenAI to decode legacy code and agentic AI to orchestrate modernization at scale, enterprises can transform these systems into engines of innovation.
To capture these dynamics, HCLTech, in collaboration with Everest Group, has released a research-based whitepaper on the evolving role of mainframes in an AI-enabled era.
