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.
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.
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.
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.
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.
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.
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.
Whether it's a mobile app, a website or an HTML5 page, COS provides SDKs written in various languages based on application types for seamless access. In case of business or user-generated content (UGC) peaks, COS scales automatically in accordance with the amounts of requests and traffic to cope with massive business access. As UGC typically has time-dimensional access characteristics, COS can stratify cold and hot data to use standard storage for hot data and low-frequency storage for cold data. Together with the lifecycle rule configuration and storage type conversion, COS reduces storage costs.
Web services generally separate frequently-changed resources from infrequently-changed resources in dynamic webpages according to a particular rule. Static resources refer to unstructured data resources that remain unchanged for a long time.
COS Standard allows static resources to be stored and distributed so as to relieve the pressure on resource servers. With infinite capacity and highly frequent read/write capabilities, the scalability and reliability of static resources are assured. Users can host the static content (including audio/video files and images) of a website in COS Standard and distribute content using Tencent Cloud CDN. Using the capacity of Tencent Cloud CDN global acceleration nodes, users can distribute hot files to edge nodes ahead of time to minimize access latency.
COS can be used as a data source for big data analysis regardless of the type of data (medical or financial data, or multimedia files such as images, audio and video).
COS supports the storage of exabytes of unconstructed data, providing high availability, high reliability, high security and high scalability. Analysis apps can be rapidly built and deployed using the Tencent Cloud Big Data Suite. After your high performance computing need is met, you can archive the data to reduce service costs and store the data long term.
Data uploaded to COS can be stored in multiple designated regions simultaneously by utilizing cross-regional duplication, ensuring that redundant data can be used to find and recover complete sets of data in a situation of accidental loss of partial data. In addition, by virtue of storing data across different regions, data loss caused by unavoidable disasters in one region can be circumvented, making multi-redundancy backup and cross-regional disaster recovery possible and ensuring data persistence and stability with yet another layer of security.
COS is billed on a postpaid basis according to actual usage. There is no minimum charge.
