Abstract:In a previous study, we suggested an information system to store, manage and treat millions of gathered patient's information. The application is able to fulfill the most important criterions, mainly measurement, monitoring, guidance, Data management and their analysis. The developed e-Health system can be accessed via the Internet. Availability, confidentiality and security issues arise that have to be considered carefully. The highest level of availability of these services is required. The main objective of this paper is to improve and enhance the both aspects of an information system: availability and reliability. The information system should be reachable constantly to satisfy the professional requirements. Today, the new technologies could help to resolve some infrastructure and connection problems. Connected machines are increasingly being introduced into safety-critical health care systems. Concretely in this study, we introduced replication, backup and restoration procedures to obtain a safe and continuous data management system in order to guarantee a highly reliable concept. By integrating the new technologies, we profited from the innovative connection utility-Internet of things -, which offers several possibilities to ensure the continued and desirable service. By implementing a distributed information system, we were able to increase the percentage of uptime to 99.8% (down time less than 20 mins/week). The vulnerability and the penetration tests were also successful and demonstrate the efficiency of the implemented redundancy, replication and restoration procedures.
