CloudTier Transparent Storage Tiering SDK provides you a simple solution to develop the cloud archiving software, it allows you to integrate your existing on-premises applications with the remote cloud storage infrastructure in a seamless, secure, and transparent fashion. The cloud tiering is a data storage technique which automatically moves data between high-cost on-permise storage and low-cost remote cloud storage, it provides a native cloud storage tier, it allows you to free up on-premise storage capacity, by moving out cooler data to the cloud storage, thereby reducing capital and operational expenditures. Cloud archiving is the process of moving data to secondary storage in the cloud, the potential benefits of cloud archiving includes lower costs and easier access, no interruption and change to your existing applications and infrastructure.

Cloud storage tiering can be widely used in telecommunications, government, oil, medical and other industries. Tiered storage is the first choice of medical PACS (Picture Archiving and Communication System, medical imaging storage and transmission systems), a lot of data in such applications are rarely visit, these data are transferred to a less expensive network storage. When users and applications access the stub files in the local storage, it is completely transparent, the system will automatically restore the data back to the stub file from the remote storage server. The network attached storage is scalable, tiered storage products provide users with an infinite online data space.
