Case Study: Deutsche Telekom achieves agile microservices transformation and massive RPA savings with Camunda

How Deutsche Telekom transformed from waterfall development on a monolithic application to an agile, microservices-based architecture

Deutsche Telekom IT GmbH (Deutsche Telekom) was burdened by a 10‑year‑old monolithic Oracle BPEL system and a waterfall development model that produced long time‑to‑market (over 12 months), vendor lock‑in, slow releases and costly regression testing. To modernize its stack and move to agile microservices, Deutsche Telekom adopted Camunda, migrating workflows to Java/Spring and embedding the Camunda BPM engines (with visibility via Camunda Cockpit) across services.

Camunda engines were deployed inside many microservices, paired with cloud/Kubernetes, a SAFe agile model and DevOps automation; Camunda enabled visualization of complex logic, alignment of human and automated tasks, and “compliance‑by‑default” across global teams. The new approach dramatically reduced runtimes and delivery cycle times, supported real‑time process monitoring (inspired by Camunda Cockpit) and helped orchestrate one of Europe’s largest RPA programs—scaling to 3,000 bots and saving millions of euros.
