Overview
Cloud Object Storage (COS) is a distributed storage solution designed to accommodate limitless data storage from any location using HTTP/HTTPS protocols. With COS, there are no limitations on data structure or format, and it offers unlimited bucket size and partition management capabilities, making it adaptable for a wide range of applications including data delivery, processing, and creation of data lakes. COS offers a user-friendly web-based interface, multi-language SDKs and APIs, command line utilities, and graphical tools. Additionally, it seamlessly integrates with Amazon S3 APIs, facilitating swift access to community-developed tools and plugins.
Benefits
Stable and Durable
Facilitate redundant data storage across diverse architectures and devices, ensuring resilience to failures and supporting remote disaster recovery. With an exceptional data durability rate of 99.999999999% (11 nines) for each object, it surpasses the durability offered by alternative storage frameworks, ensuring enhanced data integrity and reliability.
Secure and Reliable
We provide hotlink protection to prevent unauthorized access, utilizing SSL-encrypted data transmission to manage the read/write permissions of individual files. Our system is equipped with defense mechanisms against DDoS and CC attacks, safeguarding the continuity of your business operations.
Low Costs
Utilize COS for cost-effective data storage, eliminating the need for initial investments or hardware refresh cycles. Leverage lifecycle management to identify and manage cold data, thereby optimizing costs even further.
Ease of Use
Facilitate rapid batch operations on storage objects via a variety of tools, including graphical interfaces, command-line utilities, and protocol-based applications. Additionally, enables the local mounting of COS buckets, allowing for the utilization of COS as a file storage system directly from local environments.
Convenient Access
We provide comprehensive RESTful API documentation and a diverse range of SDK connection tools to facilitate efficient data management. Additionally, we offer a seamless migration tool designed to expedite data migration to the cloud, reducing associated costs for migration and connections.
Service Integration
Facilitate seamless integration with additional Cloud services, including Content Delivery Network (CDN), Cloud Infinite (CI), audio/video transcoding, file preview, and various other components. This ensures a comprehensive solution for both data storage and processing needs. Moreover, it offers compatibility with Serverless Cloud Function (SCF) to automate event notifications and processing tasks.
Features
1. Resume uploads from the point of interruption
In cases where an upload is unexpectedly halted, it is possible to resume the upload from the point of interruption, thereby minimizing the need for redundant upload attempts.
2. Tailor object headers
The object header, transmitted by a server prior to delivering HTML data to a browser through the HTTP protocol, can be customized. By adjusting the header, one can modify the response mode of a webpage or convey configuration details. For instance, adjusting the cache expiration duration of a file can be achieved without altering the file itself.
3. Offer hosting services for static websites
Static websites exclusively consist of fixed content, such as HTML or client-side scripts. When dynamic web page display is unnecessary, COS can manage the entire process, from storage to presentation. Hosting a static website on COS involves configuring a bucket associated with a custom domain name.
1. Hotlink Protection via Referer
Enable hotlink protection by configuring blocklists and allowlists for each bucket. This mechanism evaluates the Referer field in the HTTP request header against the specified lists to determine whether external requests should be permitted or denied. This feature safeguards against resource theft and mitigates associated traffic costs.
2. Cross-Region Access Control
Implement Cross-Origin Resource Sharing (CORS) for COS buckets to authorize HTTP requests from one origin to access resources hosted on another origin. This functionality facilitates seamless resource sharing across regions.
3. Multi-Regional Storage Strategy
Opt for multi-regional storage solutions tailored to your business requirements to optimize latency by selecting the closest storage region. Additionally, multi-regional storage setups offer enhanced protection through remote disaster recovery capabilities.
1. Persistent audio/video processing:
COS delivers audio/video processing capabilities tailored for mobile video applications. Leveraging an integrated SDK for seamless integration with COS, users can efficiently execute video upload, transcoding, storage, validation, and playback operations directly within COS. This establishes a comprehensive solution loop for video data upload, processing, and distribution.
2. Expert image processing:
COS offers mobile developers a diverse array of adaptable image processing services alongside highly specialized image content recognition features, including pornography detection and facial recognition. Users can directly perform image cropping, watermarking, and rotation within COS, eliminating the necessity of invoking additional APIs.
3. FTP utility:
COS furnishes users with a dedicated client tool for managing files via the FTP protocol. This tool streamlines the process of uploading and downloading files stored within COS, enhancing user convenience.
4. Hadoop integration tool:
COS provides a purpose-built Hadoop integration tool, facilitating effortless data processing tasks on COS through popular Hadoop big data processing engines like MapReduce, Hive, Spark, and Tez.
5. Diverse data migration utilities:
COS offers a range of tools for migrating data from various platforms, including Amazon S3 and Alibaba Cloud, to COS, ensuring seamless data transfer and integration.
Scenarios
COS provides multi-language SDKs for accessing diverse application types, including mobile apps, mobile websites, and HTML5 pages. It dynamically adjusts storage resources to accommodate changing demands. Recognizing that user-generated content (UGC) access requests typically peak at specific intervals, COS segregates data into hot and cold categories, storing hot data in the STANDARD storage class and cold data in the STANDARD_IA storage class. Through automated conversion of storage classes based on configured lifecycle rules, COS significantly mitigates storage expenses.
COS offers standard storage for static resources used by websites, including audio/video and image files, alleviating strain on resource servers. This standard storage solution boasts unlimited capacity and high-frequency read/write capabilities, ensuring scalable and dependable storage for static resources. Additionally, with CDN integration, files stored on COS can be pre-distributed to edge nodes worldwide, facilitating swift access with minimal latency.
COS serves as a versatile data source for big data analysis across various data types, including medical, financial, image, audio, and video data. It accommodates exabytes of unstructured data while ensuring exceptional availability and scalability. Utilizing COS, you can swiftly develop analytical applications with the Big Data Suite. Once your high-performance computing requirements are fulfilled, you have the option to archive the data, thereby reducing service costs and preserving it for long-term utilization.
Data uploaded to COS can be replicated across multiple regions simultaneously, enabling the recovery of entire datasets in case of accidental loss or damage. This feature also enhances data resilience in the face of natural disasters, ensuring robust protection and adding an additional layer of security to your data assets.
