The Esslingen Hospital is a central healthcare hospital with 662 beds funded by the local municipality. With the forward-looking approach of a modern health center and the patient-oriented organizational structures required to support this, the company can now look back on more than 150 years of history. Every year, the hospital provides care for around 28,000 inpatients and 105,000 outpatients. The qualified medical, nursing and therapy teams cover almost all fields of medicine and healthcare. As an academic teaching hospital at the University of Tübingen, the Esslingen Hospital has committed itself to providing its patients with interdisciplinary care according to the latest clinical and scientific knowledge. In addition to inpatient and outpatient diagnosis and therapy, health education, prevention and rehabilitation as well as further training and patient education are significant areas of focus.

"The migration of our SAP® systems to the virtual servers of the Telekom Healthcare Cloud was extremely fast, taking less than two days during ongoing hospital operations. Even after the changeover the ongoing operation is running reliably according to the agreed service levels, so that our doctors and caregivers can devote themselves to the care of the patients from a well-informed position. “ 

Rainer Döring, Head of IT Department at Klinikum Esslingen GmbH


As a medical service center, in addition to the quality of care the Esslingen Hospital places great importance on the actual people at the center of its activities. The constant availability of administrative information or patient data is therefore essential for the hospital's 1,760 employees. Especially in hospitals and medical care centers, it is important that infrastructure technology and IT systems work reliably in order to concentrate on the essential: the care and treatment of patients. Many companies therefore rely on standardized SAP® software. The Esslingen Hospital used to use an integrated SAP®-based ERP and HCM system, which was no longer operated in an SAP® AG data center. Due to the permanent patient care during ongoing hospital operations, the primary goal was to migrate the systems onto virtual servers in a Telekom data center within two days without any downtime.



The technical components of the Telekom Healthcare Cloud are predefined, standardized, coordinated and flexibly scalable to suit requirements. Modular service packages enable different usage models and scenarios: in the case of the Esslingen Hospital, the operation of an integrated SAP® system with development and productivity system for administration, human resources as well as medical and nursing care as standard software in the encapsulated health section of the T-Systems data center. This includes hosting the SAP® ERP applications IS-H and HCM as well as application management for the clinical information system i.s.h.med. Industry templates are maintained and continuously developed, so that no maintenance work is required by the hospital. After successful migration of the SAP® systems to virtual servers using VMware, the backup and monitoring is carried out via the data center in Frankfurt, which is subject to German law and data protection. The data communication between the connected IT systems of the company is implemented by Telekom's in-house solution Interface Manager for Healthcare (IM4HC), which functions as an integration server to receive data, convert it into the required target format and transfer it to the target system.



With SAP® applications from the Telekom Healthcare Cloud, the hospital obtains all its services from a single source: from migration to broadband integration to complete operation. The THC enables a cross-hospital, demand-oriented deployment of the SAP® applications as well as the harmonization and consolidation of the server landscape, including operational optimization. With the virtualized operation of individual servers, hospital load peaks can be flexibly absorbed without having to invest in new hardware. The operation of IT infrastructures by Telekom ensures that the hospital staff can concentrate on patient care and so improve the quality of their patient care. The hospital does not have to maintain its own hardware and uses the necessary server capacities in a scalable, flexible and cost-optimized way with high availability. The dedicated connection via the Multiprotocol Label Switching (MPLS) platform makes for secure and efficient communication.
