Case Study: LzLabs accelerates software development and multiplies testing throughput with CloudBees

LzLabs Turns to DevOps to Accelerate Software Development and Testing

LzLabs, a Zürich-based company that modernizes legacy mainframe applications with its Software Defined Mainframe, faced slow, fragmented QA and testing as it grew. Developers worked with complex legacy containers and manual processes, causing code to take days to weeks to validate; time-zone delays, hardware limits and the constraints of open-source Jenkins left the DevOps team unable to scale or give teams the control they needed.

LzLabs implemented CloudBees CI with professional services to orchestrate pipelines, enable containerized parallel testing and pool hardware resources—migrating core jobs in a single weekend. The result: tens of thousands of tests per run and 10–15 runs a day, simultaneous testing across branches, much better hardware utilization and control, faster automated merges and improved reliability backed by expert support.
