Dynamic changes in the environment with constant technological developments, influence the emergence of new forms of conducting business. One of the important forms of conducting a contemporary market activity, becomes a model of virtual organization. Generally, virtual organization is a collective of independent, specialized and often geographically dispersed business units (eg. enterprises, divisional parts of companies, institutions, individuals), combining their resources and forming the cooperation for the realization of a particular purpose.The main factor enabling the cooperation of subjects, grouped within the frame of virtual organization, are a variety of resources and ICT tools (Information and Communication Technology). High efficiency and effectiveness of ICT, requires the adoption of specific information strategies of virtual organization. Currently, the Cloud Computing is an increasingly popular service model, which provides and lets for ICT use. The aim of the article is to present information strategy of VO, based on the Cloud Computing model. To achieve that ambitious objective, at the beginning of the article, the VO outline and ICT’s role in its activity, is presented. Then, referring to the M.J. Earl’s frame, a information strategy of VO was discusses, together with the indication of the role and place of Cloud Computing in VO’s information strategy. Article tops the list of national and international Cloud Computing solutions, that can support information strategy for virtual organizations.

Information and communication technologies have become the essential part of societal life and practical activity. eHealth can be designated as a special form of information and communication technologies. It is obvious that eHealth has a great potentiality; however today there are unfortunately only a few examples of its large services. Efficient, effective, and reliable systems for remote consultations and distance education are the top requirements for eHealth. Cloud computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale sharing, innovative applications, and, in some cases, high-performance orientation. The authors define Cloud computing as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources – what can be described as “virtual organizations.” It is plausible that this technology has more potential and can improve health care services, benefit health care research, and change the face of health information technology. However, cloud computing should be rigorously evaluated before its widespread adoption. Over the past five years, research and development activities have produced protocols, services, and tools. The present article discusses the application of virtual organization technology for eHealth purposes.

Cloud-Computing gewinnt auch in Kliniken zunehmend an Bedeutung. Über das Internet bereitgestellte Lösungen verändern nicht nur Verwaltung und Logistik – im klinischen Bereich geht es zum Beispiel um die Nutzung elektronischer Patientenakten am Point-of-Care.
