Abstract Issue Given the importance, of cloud environments for mobile telemedicine information systems, focus is given in this paper on the challenges rising. We discuss the pros of the access to computing services and resources on demand without having own infrastructures, and the need of advanced interoperability data formats and application program interfaces (APIs) to facilitate the usage of the infrastructure. Description of the problem Cloud-Oriented Architecture (COA) describes the architecture, where applications act as services and serve other applications in the cloud environment. The aim is IT infrastructure and software applications to be optimized for their use in cloud computing environments. But what happens in the specific field of health as data interoperability for mobile telemedicine information systems? Results Two architectures were presented using a patient's compliance and engagement solution. A simple Representational State Transfer (REST) based architectural style was implemented in a three-layered architecture first and then compared to a cloud federation model. In the second the interaction goes through the federation via a middleware layer. Internal operations of cloud providers in the federation are still transparent to the cloud users. The middleware layer aims to coordinate the interaction with cloud users and providers in the federation. But, to avoid delays in those interactions interoperability of data formats and APIs. Lessons A Fast Healthcare Interoperability Resources (FHIR) based application was developed. Mobile telemedicine information systems are a strong instrument in patients' compliance. Many systems have proved that the used resources combined can solve clinical and administrative problems in a secure environment. Key messages The use of cloud is wide spread in the health sector. The challenge is to combine this infrastructure into one federated platform and maximize the added value by using advanced interoperability data formats and APIs.

Computational Resources

The cloud paradigm, based on the idea of delegating to the network any kind of computational resources, is showing a considerable success. The estimated trend is that the number of different cloud-based solutions, approaches, and service providers (CSP) will continue growing. Despite the big number of different cloud solutions that currently exist, most of them are “walled gardens” unable to interoperate. On the other side, a large effort is taking place in the cloud community to develop and identify open solutions and standards. In such a context the concept of cloud federation, an architecture that combines the functionalities of different CSP, is a hot topic. This chapter presents an overview of the cloud federation topic, with special focus on its most important security challenges. Furthermore, it proposes a taxonomy of possible approaches to federation. Then it proposes a comparison of security problems in cloud and grid environment, and a detailed analysis of two relevant security problems, identity management and Cyber Attacks analysis, trying to outline how they can be applied in a federated context.
