# About OBS

Object Storage Service (OBS) is a cloud storage service optimized for storing massive amounts of data. It provides unlimited, secure, and highly reliable storage capabilities at a relatively low cost. On OBS, you can easily perform storage management operations, such as bucket creation, modification, and deletion, as well as object upload, download, and deletion.

OBS provides users with unlimited storage capacity, stores files in any format, and caters to the needs of common users, websites, enterprises, and developers. Neither the entire OBS system nor any single bucket has limitations on storage capacity or the number of objects/files that can be stored. As a web service, OBS supports APIs over Hypertext Transfer Protocol (HTTP) and Hypertext Transfer Protocol Secure (HTTPS). You can use OBS Console or OBS clients to access and manage data stored in OBS anytime, anywhere. OBS is compatible with the REST APIs of Amazon S3, and supports SDKs. You can easily manage data stored in OBS and develop upper-layer service applications. OBS Console and OBS Browser are only compatible with the Amazon S3 APIs.

Cloud service infrastructures can be deployed in multiple regions, delivering flexible expansion and enhanced reliability. You can deploy OBS in specific regions for faster access at an affordable price.
