论文摘要
由于提供给视频流提供商提供的出色功能,例如使用虚拟机和存储服务器以较低的速度使用,因此采用了云技术来处理视频流。视频流提供商准备了几种相同视频的格式,以满足所有用户的设备规格。云中的视频流是转码或存储的。但是,存储所有视频格式仍然昂贵。在这项研究中,我们开发了一种优化云存储的方法。特别是,我们提出了一种方法,该方法可以决定在哪些视频中存储哪些视频,以最大程度地减少云服务的整体成本。提出的方法的结果是有希望的,当在存储库中经常访问的视频数量以及视频观看量增加时,它显示出有效性。提出的方法将使用云服务的成本降低了22%。
Cloud Technology is adopted to process video streams because of the great features provided to video stream providers such as the high flexibility of using virtual machines and storage servers at low rates. Video stream providers prepare several formats of the same video to satisfy all users' devices' specifications. Video streams in the cloud are either transcoded or stored. However, storing all formats of videos is still costly. In this research, we develop an approach that optimizes cloud storage. Particularly, we propose a method that decides which video in which cloud storage should be stored to minimize the overall cost of cloud services. The results of the proposed approach are promising, it shows effectiveness when the number of frequently accessed video grow in a repository, and when the views of videos increases. The proposed method decreases the cost of using cloud services by up to 22%.
