How SIXT Uses IBM Instana to Cut Problem Resolution Time by 70%

SIXT, a global mobility services company offering vehicle rental, car sharing, ride hailing, and car subscriptions across 110+ countries, operates an exceptionally complex cloud-native infrastructure. With 170+ AWS accounts supporting 10 platforms, over 2,000 services, 6,500+ containers, and 9,000+ deployments, the organization needed robust observability to maintain service reliability and accelerate incident response.

The company implemented IBM Instana Observability to gain end-to-end visibility across their entire infrastructure. Instana's automatic discovery capabilities map applications and their relationships, while end-to-end tracing analyzes requests across services. The platform correlates infrastructure-to-software performance, providing customizable dashboards that give engineering teams the insight needed to troubleshoot issues and achieve rapid recovery.

The results were significant — SIXT achieved a 70% decrease in problem detection and resolution time and 50% faster detection of availability anomalies. The platform enabled successful cloud migration completion within schedule despite performance challenges, while managing thousands of software deployments monthly. SIXT is now planning OpenTelemetry standard integration across their programming frameworks to further improve visibility and control over service interactions.
