Zusammenfassung

Die Zuverlässigkeit der IT-Services ist die Voraussetzung für die reibungslose Ausführung von Geschäftsprozessen und entscheidet so wesentlich über den wirtschaftlichen Erfolg von Unternehmen. Um den Ausfall von IT-Services zu vermeiden, ist es wichtig ihre Resilienz zu erhöhen also ihre Fähigkeit den Ausfall von untergeordneten IT-Services abzufangen und nach einem erfolgten Ausfall zum Normalbetrieb zurückzukehren. Bisher wurden resilienzsteigernde Maßnahmen nur manuell initiiert. Datenbasierte Ansätze ermöglichen dies zu automatisieren und die Resilienz von IT-Services zu steigern. Daher wird mittels einer methodisch durchgeführten Fallstudie Erfahrungen und Einblicke in die Umsetzung eines datenbasierten Systems zur IT-Service-Resilienzsteigerung ermittelt. Die Fallstudie zeigt, dass eine schnellere Erkennung von resilienzrelevanten Ereignissen erreicht wird und die Erfassungstiefe der relevanten Ereignisse deutlich gesteigert werden kann. Zusammen mit der automatischen Veranlassung resilienzsteigernder Maßnahmen kann eine deutliche Steigerung der Resilienz der IT-Services erreicht werden, die sich auf die Zuverlässigkeit der unterstützten Geschäftsprozesse deutlich positiv auswirken kann.

Abstract

The reliability of IT services is the prerequisite for the smooth execution of business processes and is thus a key factor in the economic success of companies. In order to avoid the failure of IT services, it is important to increase their resilience, i. e. their ability to intercept the failure of subordinate IT services and return to normal operation after a failure. So far resilience-increasing measures were initiated only manually. Data-based approaches make it possible to automate and to increase the resilience of IT-services. Therefore, experiences and are captured by means of a methodically accomplished case study on the conversion of a data-based system for the improvement of resiliency of IT-services. The case study shows that a faster recognition of events is reached and the collection depth of the relevant events is clearly increased. Together with the automatic a clear increase of the resiliency of the IT-services was achieved, improving the reliability of the supported business processes clearly.
