MEDHOST Streamlines Healthcare Software Modernization at Scale

The Challenge

MEDHOST, a leader in healthcare software solutions, supports more than 1,000 healthcare facilities across the U.S., including many in rural communities. Its platform plays a critical role in hospital operations, making ongoing modernization both essential and risky. With software deeply embedded in clinical workflows, every update must meet strict compliance standards and pass rigorous testing and certification processes.

“Our software is not just about functionality; it’s about adhering to legal compliance and government regulations, especially in the rural communities where we operate,” explains Pandian Velayutham, MEDHOST’s VP of Technology Strategy. These regulatory and certification demands introduced additional testing overhead and significantly raised the stakes for every infrastructure change.

Over time, MEDHOST’s infrastructure had grown large and increasingly complex. Their move toward more cloud-based systems added further intricacies, especially when managing upgrades, dependencies, and security fixes across legacy environments. Many of their applications, including legacy Java services and infrastructure-as-code components like Terraform, needed modernization but were too resource-intensive to address manually.

Code quality and consistency varied across teams and repositories. The team needed a better way to modernize its software portfolio: one that could accelerate transformation & reduce tech debt without compromising reliability, compliance, or developer productivity.

The Solution

"Your code quality is going to get much, much better, and you are going to have fun upgrading to the next version instead of fearing it."

To accelerate modernization without compromising quality or compliance, MEDHOST partnered with Moderne to overhaul legacy Java services and Spring Boot applications—key areas for improving maintainability and security. One of the first major milestones was migrating core systems to Java 17, unlocking immediate performance gains and long-term platform stability.

Rather than treating upgrades as ad hoc projects, the engineering team codified transformation logic into reusable recipes using Moderne’s Lossless Semantic Tree (LST) model.

They have also implemented a CI check for every commit to enforce security and quality standards in their development process, including:

  • Java security best practices
  • Secrets detection 
  • OWASP Top 10
  • Dependency upgrades
  • Common static analysis fixes
  • SLF4J logging best practices

This CI-driven approach turned previously manual, error-prone upgrades into a seamless part of daily development—ensuring modern Java adoption and secure, production-ready code without slowing delivery. Front-end frameworks and infrastructure tooling also benefitted from this unified modernization strategy, replacing brittle scripts with scalable, reliable automation.

Moderne has been a game-changer. It gave us the ability to modernize safely and at scale, without adding more burden to our developers

Results

By adopting Moderne, MEDHOST accelerated modernization across its ecosystem while improving code quality, consistency, and developer confidence. Manual remediation work that once took weeks was now handled automatically at scale—resulting in a 30–50% reduction in time spent on refactoring tasks. That time savings allowed teams to focus more energy on building new features, improving user experiences, and driving long-term innovation.

One of the biggest achievements was the seamless migration to Java 17. With recipe-based automation and built-in quality checks, MEDHOST completed the transition faster and with greater certainty than previous upgrades. Now, the team is preparing for their next leap to Java 21 or 22—an upgrade they’re approaching with confidence thanks to Moderne.

The impact extended beyond Java. With support for front-end frameworks and Terraform, MEDHOST has broadened its modernization scope, creating consistent upgrade paths across previously siloed parts of the codebase. Embedded recipes help junior developers contribute more effectively, reinforcing best practices and accelerating onboarding.

Today, MEDHOST thrives on a modernization approach that’s fast, scalable, and safe—enhancing the impact of its engineering org without compromising on the quality, compliance, or care its customers rely on.

Moderne has definitely improved our code quality and helped us standardize our code. It is an important tool that positions us to keep pace with the rapidly evolving technology landscape.
