Implementation of Video and Medical Image Services in Cloud The main subject of this paper is how to construct virtualization in the cloud for implementing video and medical image services. The framework of cloud service contains the infrastructure, OS, virtual machines, platform, cloud web application services, and cloud devices. We build medical image and video services on cloud IaaS environment, which integrates KVM and OpenNebula open sources to provide a cloud virtual environment for end users. Also, Hadoop open source, as cloud PaaS, is used for these two cloud services. This paper realizes medical image and video services that are easy for users to understand, access, and operate with them in the cloud. The proposed system can improve medical imaging storage, transmission stability, and reliability while providing an easy-to-operate management interface.
