Cloud Object Storage

Secure, stable, massive, convenient, low-delay, low-cost cloud storage services

Tencent Cloud Object Storage (COS) is a distributed storage service offered by Tencent Cloud for unstructured data and accessible via HTTP/HTTPS protocols. It can store massive amounts of data and features imperceptible bandwidth and capacity expansion, making it a perfect data pool for big data computation and analytics. COS provides a web-based management interface, multilingual SDK as well as command-line and graphical tools and is fully compatible with S3's API, allowing direct access to community tools and plugins with ease. It can also be used alongside other cloud products such as global CDN nodes for acceleration services and Cloud Image for one-stop image solutions.

Benefits

Stable and Durable

COS enables redundant storage of data across multiple architectures and devices and supports remote disaster recovery and resource isolation to provide up to 99.999999999% data persistence for each object, providing better data persistence than other storage architectures.

Secure and Reliable

Hotlink protection is supported to block malicious access. Data transmission can be encrypted with SSL technology to control the read/write permission of each file. Defense systems can effectively defend against DDoS and CC attacks to ensure your business operates normally.

Low Costs

There is no need for the traditional purchase, deployment and OPS, or to pay to reserve storage space in advance. The service is used as needed, and billed based on use. Lifecycle management can be used to identify cold data to further reduce costs.

Ease of Use

COS supports a variety of methods for conducting batch operations on storage objects such as graphical programs, command-line tools and protocol tools, further enhancing its ease of use. It also offers tools capable of mounting buckets to your local storage, enabling you to use COS just like a local file storage system.

Convenient Access

COS has a detailed RESTful API manual and a wide variety of SDK connection tools. There is also a seamless migration tool to quickly migrate your business into the cloud, helping you avoid high migration and connection costs.

Service Integration

COS can be integrated with other Tencent Cloud products, including CDN acceleration, Cloud Image processing, audio/video transcoding, file preview and other components, to provide an integrated solution for storage and processing. In addition, COS can be used as a data pool for big data computing and provide the data source for big data analysis and computing.

Features

Object Management
Security
Big Data and Open Capability

Resume uploads from the breakpoint
If an upload is unexpectedly terminated, you can resume the upload from the breakpoint to reduce the time spent on repeated uploads.

Customize object headers
The object header is a string sent by a server before it sends HTML data to a browser via the HTTP protocol. You can change the response mode of a page or send configuration information by modifying the header. For example, the cache expiration time can be changed, but the file itself will not be changed.

Static websites
Static websites only contain static content (such as HTML) or client-side scripts. Users who don't need to display dynamic webpages can use COS to complete the whole process from storage to display. Users can host a static website by configuring a bucket (linked with a custom domain name) for the website on COS.
