This document introduces the use cases of COS.
Application Data Storage
Whether it's a mobile APP, website, or HTML5 webpage, COS provides language SDKs based on application type for seamless access. During business surges with sudden increases in user-generated content (UGC), COS automatically scales according to traffic needs, handling peak business pressures easily. Since UGC normally has time-dimensional access characteristics, COS enables hot and cold data tiering—hot data uses standard storage while cold data uses infrequent storage. In conjunction with lifecycle rule configuration, switching storage classes effectively reduces storage cost.
Data Processing
For user-submitted data in COS, COS can perform editing, processing, and review operations based on Cloud Infinite (CI): for image data, users can crop, scale, transcode, sharpen, or add watermarks; for video data, users can transcode, add watermarks, or extract frames; for document data, users can generate images or HTML for preview and add watermarks to preview images. It also supports content review for images, audio and video, and text, such as detecting pornography and illegal content. Content Delivery
Website services usually separate frequently changing and long-term unchanged resources in dynamic web pages based on certain rules. Static resources refer to long-term unchanged unstructured data resources. Standard storage provides storage and distribution capability for static resources, reducing the pressure on resource servers. It leverages the characteristics of unlimited capacity and high-frequency read/write to offer expandable and reliable storage for static resources. Users can host all static content in websites (including files such as audio, video, and images) in standard storage and use Tencent Cloud CDN to distribute content. Combined with the ability of Tencent Cloud CDN global acceleration nodes, hot spot files can be delivered to edge nodes in advance to reduce access latency.
Big Data Analysis
Regardless of whether users store medical or financial data or multimedia files such as photos and audio-video, COS can be used as a data source for big data analysis. COS supports storing EB-level unstructured data with high availability, reliability, security, and scalability. In conjunction with Tencent Cloud Big Data Suite, it enables quick creation and deployment of analytical applications. Once high-performance computing requirements are completed, data can be converted to archive storage to reduce service usage costs for long-term data retention.
Disaster Recovery and Backup
User data stored in COS can be replicated across multiple designated regions through the cross-region replication feature, ensuring against accidental data loss by locating and restoring complete data using redundant data. At the same time, because multiple data copies are stored in different regions, it avoids the loss caused by force majeure disasters in a single region, ultimately resulting in multi-redundancy backup and cross-regional disaster recovery effects. This ensures data durability and stability, adding multiple security mechanisms for important data.
