Under the Hood: Dismantling the Heavyweight Monolith

Written By David Dollar

True modernization isn't just a "lift-and-shift" into a cloud container. If you simply copy your old architecture patterns into the cloud, you're just paying steep cloud prices for legacy friction.

Here is exactly how Integri's engineering team modernized the core runtime infrastructure of a high-maintenance enterprise monolith:

  • Runtime Evolution: Swapped out heavyweight, high-license app servers for lightweight Spring Boot applications running on Kubernetes.

  • High Availability Scaling: Implemented active session replication within Kubernetes to ensure horizontal scalability and zero data loss during automated pod restarts—no enterprise server bloat required.

  • Open Security Standards: Replaced proprietary security silos by centralizing identity management through standard Keycloak OAuth2 and OpenID Connect protocols.

  • Automated Checkpoints: Transformed manual QA into an automated checkpoint within the CI/CD phase using a custom Selenium framework, stopping regressions before they ever smell production.

By fixing distributed transactions at the application level and ensuring stateful UI scaling, we turned a legacy liability into an agile, cloud-ready framework.
