# Application Scenarios

- OBS can be used to access and store massive objects of all formats. As a web service, storage and access operations can be performed on OBS anytime at any location over the Internet. For all Internet-based application programs such as websites, video applications, Software as a Service (SaaS) applications, web disks, and mobile apps, developers can use OBS as the ideal choice to store data of these applications. In addition, OBS reduces costs in the following scenarios: backup, big data storage, and archiving.
- OBS features unlimited scalability (large capacity and linear expansion), cost effectiveness (zero initial investment, more cost-effective as the used capacity increases), robust reliability, and enhanced security (end-to-end security for access, transfer, and storage). With OBS, developers can focus on business innovations instead of underlying storage technologies, because they do not need to plan storage capacity as their businesses grow. This way, data can be quickly accessed and capacity is highly scalable, and robust reliability and enhanced security are available. Most importantly, IT costs can be reduced significantly.

OBS can be used in video surveillance, video on demand (VOD), backup and archiving, high-performance computing (HPC), mobile Internet, and enterprise cloud box (web disk) scenarios.
