Case Study: Fiserv Migrates to Java and Spring Boot with Zero Downtime Using Cloud Foundry

With Cloud Foundry, Fiserv Migrates to Java and Spring Boot With Zero Downtime

Fiserv, a global financial services technology company, needed to migrate its IT services from an existing platform and language to Java and Spring Boot without disrupting operations. Working with Cloud Foundry, Fiserv faced the challenge of maintaining zero impact and zero downtime while modernizing services, supporting compliance, and preserving scalability across its environment.

Cloud Foundry enabled Fiserv to complete the migration in six weeks using automated platform features, blue-green deployments, BOSH-managed infrastructure, and a pipeline-driven approach for build, test, and deploy. The result was a zero-downtime transition with improved recruitment, retention, training, compliance, automation, and shorter lead times, while giving the team better visibility through metrics and logging.
