Noventiq modernizes a complex monolith into a scalable SaaS on AWS

“CAST reduced discovery time by 30%, revealing modernization risks along with mitigations upfront.”

Yogesh Sharma

Head – App Modernization

CAST Highlight and CAST Imaging enabled Noventiq to accelerate discovery, shape the cloud modernization roadmap, and de-risk modernization of a complex monolithic application.

Challenge

A leading Hospital Management Suite and EMR provider needed to move a monolithic platform to a SaaS-ready model. Visibility into the legacy codebase was limited, obscuring module boundaries, hidden dependencies, and component obsolescence. Selecting the candidates for extraction was risky and slow. Open-source vulnerabilities and compliance concerns compounded uncertainty. Manual analysis threatened delays, higher costs, and disruption for clinical users relying on workflows.

Solution

Noventiq leveraged CAST Highlight & CAST Imaging to uncover the application’s structure in a week.

Auto blueprinting made module interactions clear, while dependency maps exposed hidden links and good candidates for SaaS extraction. Complexity scores set priorities. Old and non-cloud parts were flagged, and open-source risk checked. The result was a risk-aware plan covering service extraction, multi-tenant data changes, replatforming, and security and governance.

Results

The customer accelerated modernization: 30–35% effort saved during discovery, 25% risk reduction by surfacing hidden dependencies early, and a 40% cut in roadmap design time. A component inventory improved decision-making speed.

The stepwise path enabled accelerated SaaSification on AWS with minimal disruption, culminating in a cloud-native platform delivering scalability, maintainability, and compliance while reducing modernization risk and aligning business and engineering.

A case study on how Noventiq used CAST Highlight and CAST Imaging to accelerate discovery and de-risk modernization of a large monolithic application.

Analyzed 2.2 million lines of code and uncovered structure in about one week

Used auto-blueprinting and dependency maps to identify module interactions and candidates for software-as-a-service extraction

Applied complexity scoring to prioritize work; flagged old and non-cloud parts; checked open-source risk

Reported results: 30–35% effort saved in discovery, 25% risk reduction from early dependency visibility, and 40% less time to design the cloud modernization roadmap
