Benefits

High Reliability

KS3 is an object storage service with high reliability. KS3 provides a redundant storage that supports data replication across regions, availability zones (AZs), and devices. KS3 ensures 99.999999999% of data durability, providing a stable and reliable data storage service.

High Security

KS3 supports verification of EB-level data, AES-256 server-side encryption, and signature verification using public and private keys. KS3 also provides features such as multiple replicas, permission management for individual files, and hotlinking protection. All these security features safeguard your important data stored in KS3.

High Performance

KS3 supports data access at high concurrency and large bandwidth, and can effectively handle traffic surges. With its optimal upload and download performance, KS3 ensures excellent user experience.

Convenient Management

KS3 provides a variety of management tools, including an easy-to-use console, SDKs for multiple languages, RESTful API, and command-line tools. In addition, KS3 supports flexible access policies, audit logs, and project management. You can upload, download, and manage data anywhere and anytime.

Features

Data Storage

KS3 provides a cost-effective storage solution that can store massive amounts of data. KS3 supports the Standard, Infrequent Access, and Archive storage classes. You can select a storage class based on your data access frequency to minimize costs.

Data Security

KS3 API supports HTTPS to ensure data security during transmission. KS3 supports client-side encryption, AES-256 server-side encryption using managed keys, and custom server-side encryption using customer-provided keys. KS3 also supports cost-effective disaster recovery and data backup through cross-region replication.

Permission Control

KS3 provides multiple methods that allow you to control permissions on files, such as ACLs for files and buckets, IAM, and role-based authorization. KS3 provides hotlinking protection that allows you to configure an IP address blacklist or whitelist for access control. KS3 also supports image protection to prevent others from using your image files without authorization.

Data Management

KS3 provides various data management features, such as lifecycle management, mirroring-based back-to-origin, hotlinking protection, cloud monitoring with Kingsoft Cloud Monitor Service, project management, and permission management.

Data Migration

KS3 allows you to migrate massive amounts of data from third-party data sources to KS3 by using KS3Up-tool. KS3 supports incremental, resumable, and concurrent upload of data. In addition, the mirroring-based back-to-origin feature allows you to migrate data to KS3 without interrupting your service.

Management Approach

KS3 allows you to manage data by using the console, RESTful API, and SDKs for multiple languages. To help you manage data, KS3 also provides the GUI tool KS3 Explorer, the command-line tool KS3Util, and the data migration tool KS3Up-tool.

Data Processing

KS3 can work with CDN by acting as the origin. CDN accelerates content delivery by allowing users to retrieve files from the CDN nodes that are closest to them. KS3 also provides features such as thumbnail, watermark, clipping, and rotation to offer high-quality image processing.

Cross-Origin Resource Sharing

KS3 supports Cross-Origin Resource Sharing (CORS) that allows web applications in one domain to interact with resources in another domain. With the CORS support, you can build rich web applications with KS3.

	KS3	Traditional File System
Interface	KS3 provides a RESTful API based on HTTP or HTTPS. KS3 allows you to upload and download data by using the PUT, POST, and GET methods, and delete data by using the DELETE method.	A traditional file system that is compatible with Portable Operating System Interface (POSIX) provides functions such as open, close, read, write, and lseek for file management.
Data organization	KS3 organizes files in a flat structure that consists of two layers: the bucket layer and the object layer. Each object represents a file and must be stored in a bucket. Buckets cannot be nested. The flat structure and key-value access mode can better address data management requirements.	A traditional file system organizes files in a tree structure called a directory tree. When the stored files reach the millions, both the frequency with which the file system is accessed and the concurrent traffic per unit time will be unmanageable. In this case, the tree structure can result in high overhead and affect the underlying storage system.
