Disaster Recovery Infrastructures, which have become a common aspect of all major IT infrastructures, could transform to Fault Tolerant Infrastructures in order to increase productivity, effectiveness and availability. This paper suggests a methodology for the transformation of High Availability Systems on which Disaster Recovery Infrastructures are based, to Fault Tolerant Production Infrastructures and establishes some Key Performance Indicators (KPIs) as a means to measure the effectiveness of the approach, adopting the principles of the Information Technology Infrastructure Library (ITIL) framework to a cost cutting, ecological and security-aware environment.
