Case Study: E.ON reduces MTTR and accelerates innovation with AppDynamics

Step Change in IT Performance at E.ON with AppDynamics

E.ON UK, a major energy provider, depends on its Integrated Customer Environment (ICE) — an Oracle/.NET WCF platform that manages customer records and core services — to keep millions of customers served. As the business and IT landscape grew more complex with frequent releases and third-party components, E.ON lacked real-time visibility into the application middle tier, leading to costly downtime, slow root-cause identification, and direct impact on revenue and customer service.

E.ON deployed AppDynamics, which installed quickly, auto-baselined performance, and revealed the web‑services middle tier so teams could pinpoint and fix issues fast. The platform cut mean time to resolution, enabled a faster cycle of innovation (resolving a blocking performance problem in 15 minutes), produced unified business/IT dashboards for better decisions, and helped prevent incidents while supporting daily production releases.
