Abstract
with the rapid improvement of computation facilities, healthcare still suffers limited storage space and lacks full utilization of computer infrastructure. That not only adds to the cost burden but also limits the possibility for expansion and integration with other healthcare services. Cloud computing which is based on virtualization, elastic allocation of resources, and pay as you go for used services, opened the way for the possibility to offer fully integrated and distributed healthcare systems that can expand globally. However, cloud computing with its ability to virtualize resources doesn't come cheap or safe from the healthcare perspective. The main objective of this paper is to introduce a new strategy of healthcare infrastructure implementation using private cloud based on OpenStack with the ability to expand over public cloud with hybrid cloud architecture. This research proposes the migration of legacy software and medical data to a secured private cloud with the possibility to integrate with arbitrary public clouds for services that might be needed in the future. The tools used are mainly OpenStack, DeltaCloud, and OpenShift which are open source adopted by major cloud computing companies. Their optimized integration can give an increased performance with a considerable reduction in cost without sacrificing the security aspect. Simulation was then performed using CloudSim to measure the design performance.
Highlights
Much research effort has been put into the design and development of novel e-Health services and applications, their interoperability and integration remain challenging issues
That was accompanied by setting a Platform as a Service (PaaS) on OpenShift for connecting the private cloud to other health care services, mobile and web applications for clinicians and patients, and resources provided by different cloud providers
The rest of this paper is organized as follow; section 2, introduces a brief note about private cloud implementation, section 3, explains the potentials of expanding the private cloud infrastructure by incorporating other public cloud providers, section 4, discusses a medical application that took advantage of the implemented hybrid cloud, section 5, provides a simulation analysis to assess the performance benefits behind the proposed implementation, and we concluded the paper by a discussion section
Summary
Much research effort has been put into the design and development of novel e-Health services and applications, their interoperability and integration remain challenging issues. Health services deal with large amount of private data which needs to be both fully protected and readily available to clinicians. The commercial model is to pay for the infrastructure that is used This means the designer doesn’t have expensive servers idling, and if there is a spike in the visitor numbers, the designer doesn’t have to worry if the hardware will cope. We provide a closer look into the implementation of healthcare infrastructure using a private cloud based on OpenStack. That was accompanied by setting a PaaS on OpenShift for connecting the private cloud to other health care services, mobile and web applications for clinicians and patients, and resources provided by different cloud providers. The rest of this paper is organized as follow; section 2, introduces a brief note about private cloud implementation, section 3, explains the potentials of expanding the private cloud infrastructure by incorporating other public cloud providers, section 4, discusses a medical application that took advantage of the implemented hybrid cloud, section 5, provides a simulation analysis to assess the performance benefits behind the proposed implementation, and we concluded the paper by a discussion section
