APP MICROSERVICES & DIGITAL TWINS
Unlocking legacy portfolios through
overlay intelligence
For global enterprises relying on core platforms maintained by traditional IT service providers, the application portfolio
is often locked in "lights-on" support mode. Tholons builds an intelligent microservices layer directly on top of
legacy core systems — injecting modern features, AI capability, and cloud connectivity without uprooting the core.
