如今，随着无线连接的不断发展，人们几乎在任何地方都能访问云端的所有资源。在这种情况下，就电子健康而言，各类机构可以利用这一事实，在电子健康服务方面部署基于云的解决方案。本文针对电子健康档案（EHRs）管理系统的不同场景提出了两种基于云的解决方案。我们研究了2005年至2011年间在医学文献数据库（Medline）中发表的有关基于云的电子健康服务实施的文章。为了分析云计算部署的最佳场景，我们对一家大型医院和一个初级医疗保健中心网络的两种解决方案进行了研究。通过亚马逊计算器工具对这两种场景的实施成本进行了经济估算。作为分析的结果，根据不同场景提出了两种解决方案：对于一家大型医院的云解决方案部署，假定采用一种典型的云解决方案，即只租用所需的服务。另一方面，对于多个初级医疗保健中心，建议建立一个网络，将这些中心与一个云环境相互连接。最后，考虑到部署混合解决方案的情况：即带有图像的电子健康档案将存储在医院或初级医疗保健中心，其余的则迁移到云端。
Nowadays with the growing of the wireless connections people can access all the resources hosted in the Cloud almost everywhere. In this context, organisms can take advantage of this fact, in terms of e-Health, deploying Cloud-based solutions on e-Health services. In this paper two Cloud-based solutions for different scenarios of Electronic Health Records (EHRs) management system are proposed. We have researched articles published between the years 2005 and 2011 about the implementation of e-Health services based on the Cloud in Medline. In order to analyze the best scenario for the deployment of Cloud Computing two solutions for a large Hospital and a network of Primary Care Health centers have been studied. Economic estimation of the cost of the implementation for both scenarios has been done via the Amazon calculator tool. As a result of this analysis two solutions are suggested depending on the scenario: To deploy a Cloud solution for a large Hospital a typical Cloud solution in which are hired just the needed services has been assumed. On the other hand to work with several Primary Care Centers it's suggested the implementation of a network, which interconnects these centers with just one Cloud environment. Finally it's considered the fact of deploying a hybrid solution: in which EHRs with images will be hosted in the Hospital or Primary Care Centers and the rest of them will be migrated to the Cloud.
