Abstract
Dynamic on-demand service has become the crucial part in cloud computing according to the user’s requirements. Cloud storage is clearly the top choice for archiving media assets, by choosing the public cloud for active, deep archive needs. Video on demand, media distribution system in cloud allowing users to access video, facilitating immediate download and view of data without traditional video playback devices. On demand service of video requires infrastructure resources to handle large load fluctuations. Major challenges of video demand services are delays in simultaneous video uploading, processing, accessing and traffic caused by exhaust services. Also, there are concerns over the security of assets stored in a public cloud remains. In this paper, an ample analysis is presented on file storage encompassing fragmentation, compression, encryption security concerns in cloud storage and access. The limitations in the existing is also provided and hence outlined the research direction towards an efficient storage mechanism with a secured access providing a reliable media data transmission between data owner and users in public cloud environment.
Highlights
Cloud computing is the on demand availability of computer system resources to the users without their direct management
The survey aims to graph the research on storage services provided by public cloud environment for multimedia file, an unstructured data having high dimensionalities
Geospatial images are stored in Meta Raster Format (MRF) format, a high performance web tile service storage format which splits the rater dataset into three files such as metadata file, data file and index file
Summary
Cloud computing is the on demand availability of computer system resources to the users without their direct management. It provides network access, resource pooling, elasticity, on demand self-service and measured service (pay per usage cost). Resource pooling, elasticity, on demand self-service and measured service (pay per usage cost) All these services are provided by cloud service platform through the internet to the users. Cloud offers platform as a service facility through web servers and software as a service via application interfaces. Customers gain access to hardware and software with the subscription based fee in the public cloud. Integration of security policies and identity access management between customers and public cloud providers are the major concern. Benefits of cloud storage are less storage cost, enlarged operational flexibility and optimized backup infrastructure
