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.
Non-Invasive Abstraction Layer
API and integration wrappers intercept and exchange data without altering core source code.
Overlay Application Microservices
Modular deployment of 5–10+ high-demand business capabilities on top of legacy platforms.
Cloud & Data Enablement Fabric
Bridging on-premise systems to multi-cloud environments for real-time telemetry and data.
Enterprise Digital Twin Architecture
A unified digital twin combining legacy core and modern microservices for parallel validation.
MODERNIZATION ROADMAP
Three phases from audit to full portfolio modernization
