Stable, persistent, and trust-worthy data
Stores data across multiple infrastructures and devices in a redundant manner; supports remote disaster recovery and user resource isolation, implementing 99.999999% durability for objects.
It is difficult to implement data storage in multiple copies in multiple regions. System stability completely relies on hardware.
Comprehensive protection, authority-based management
Provides anti-leeching function to block malicious accesses; provides DDoS and CC protection to filter attacking data packets; provides a multi-level permission management system to ensure that data is under
Building up security takes a long time, and investments are costly; plus, vulnerabilities and risks will still exist.
Smart scheduling, reliable access
Supports incremental uploading to optimize efficiency. While uploading, COS chooses the best path from out of over 70 nodes, with a connection success rate of 99.9%. While downloading, with CDN enabled,
Inadequate bandwidth creation. Access quality cannot be guaranteed during data upload/download.
Pay-by-usage, auto expansion
No costs for purchase, deployment and ops; pay according to your actual usage without minimum cost; expand any time as required
Deployment in early phase, capacity expansion, and maintenance in later phases are costly.
Easy to use
Convenient access, one-click migration
Provides a detailed RESTful API access description, rich SDK access tools, and seamless migration tool to help you migrate services to the cloud quickly
Successful access can be achieved only under guidance of professional personnel.
Variety of functions, diversified handling methods
COS provides rich plug-ins to implement CDN acceleration, photo processing, audio/video processing, file preview and format changing.
Professional enterprise software needs to be purchased.
Multiple access modesCOS provides standard RESTful APIs, helping you to implement features like uploading, downloading, query and deleting. In addition, SDK in multiple coding languages are provided, allowing for easy re-development without complicated access. You can also manage and monitor data easily with the Web console
High-speed uploading and stable downloadingCOS provides you with over 70 uploading nodes. While you’re uploading data, COS will select the best path with a connection rate of 99.9%. While you’re downloading data, together with CDN, COS can send source site content to the nodes nearest to the edge of the terminal, so as to increase connection success rate and decrease access delay
Powerful data management capabilityCOS provides many uploading and downloading features, including batch uploading (to shorten queue time), resumable data transfer/downloading (to solve the issue of uploading/downloading large files under unstable networks); fragment uploading (to separate large files into fragments and upload, so as to increase transfer success rate). COS supports a single upload of 50G and storage of 50T
Flawless permission systemCOS provides a cooperator mechanism and a resource permission system, allowing you to assign detailed permissions to each role of the team
Anti-leeching mechanismCOS provides anti-leeching configuration functions for buckets, and supports blacklist/whitelist. It uses the Referer field in the HTTP header to effectively restrict access sources and mask malicious access, in an effort to ensure normal service operations.
Multiple attack prevention methodsCOS is used in collaboration with CDN to effectively defend against DDoS and CC attacks; and to filter out malicious attack data packets, returning traffic to normal.
Simultaneous backup to multiple data centers in different regionsEvery piece of data has 3 copies made to ensure security; 99.95% service availability, and 99.999999% data reliability. Multiple regions are available to provide remote disaster recovery and resource isolation, thereby ensuring high availability and automatic disaster recovery of services.
Pay-by-trafficTraffic uploading is free of charge and the minimum fee is RMB 0. 50GB storage space, 10G IDC traffic, and 10G CDN retrieval traffic are offered free of charge, and the storage space out of the preceding is charged at a price as low as RMB 0.154/GB/month.
Flexible expansionThe capacity of COS storage CVM is as high as 500PB+ and the mass distributed architecture supports automatic expansion indefinitely. Users can focus on their services and business, without having to worry about increases in usage.
Smooth CDN accelerationCOS distributes content of source sites to the nodes nearest to users so that users can obtain required content nearby; thereby improving user access response speed and success rate. More than 400 nodes are distributed globally, with 20T+ bandwidth to achieve top-notch acceleration capabilities, surpassing similar products by 30%.
Persistent audio and video processingCOS supports customization of mobile applications using UGC small and short videos. Only the SDK needs to be integrated to rapidly access and control video uploading, transcoding, storage, review, and play.
PS-level picture processingCOS provides mobile developers with highly reliable picture storage services, picture uploading and downloading at high speeds with high success rates, diversified and flexible picture processing and processing of customized images.
File preview and format conversionCOS supports file preview and compressed package list preview, and provides preview of multiple types of files, including .doc(x), .ppt, .xls, .rtf, .pdf, .txt files, and preview of file lists in compressed packages such as .7z, .rar, and .zip packages. It also provides pre-transcoding and real-time transcoding.
