After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all, you can test whether the CDN acceleration is successful. There are many elements involved in CDN acceleration. Today, I will introduce the solution of cdn video storage.

I. background of the programme

With the vigorous development of high-definition and ultra-high-definition video, users' desire for high-quality video experience puts forward higher requirements for the concurrent processing of the network and the storage capacity of the content platform. As an important part of the industrial chain, CDN (content Distribution Network) has entered the fast lane of standardized development. The rapid development of CDN will provide strong support for the construction and popularization of content distribution platform. With the continuous expansion of business, the storage platform with horizontal expansion, flexible self-adaptation and supporting massive client concurrent access conforms to the development trend of the ultra-high-definition video era.

II. Challenges

1. Traditional storage can not meet the new business requirements of the origin server.

Origin server is the core content library of video-on-demand platform. With the passage of time, more and more programs and content are purchased, and storage needs to support dozens or even hundreds of PB of content. However, due to the head or architecture, the traditional storage platform can not store all content, and can not achieve non-downtime expansion in the face of the need for expansion.

2. There are security problems in the traditional means of data protection.

Due to the limitations of capacity and architecture, traditional storage often uses multiple sets of storage for data storage, and each set of storage can only use mechanisms such as RAID to ensure data security. Due to the increasing amount of data, more and more storage nodes, single point of failure and other problems are prominent.

3. Traditional storage can not cope with the huge traffic pressure of massive users.

The growth of front-end users brings higher traffic output, but in traditional mode, the back-end storage is limited by the head, and the stable video stream output of storage cannot be improved through expansion. In order to improve the viewing experience of users, other links such as CDN and lines are needed to accelerate video stream processing.

4. Traditional storage can not support fast indexing and video post-processing requirements.

Traditional storage does not support indexing, and cannot directly publish or deliver content to the nearest service node through indexing, caching, stream splitting, multicast and other technology. it also can not support video intelligent processing engines such as video content analysis, content audit, intelligent production and so on.

III. Solutions

CDN video storage solution provides a unified storage platform for video data on the origin server. Through Shanyan massive object storage (SandStone MOS), local disks on multiple servers are integrated to form one or more large-scale storage resource pools to ensure data security and business continuity through the data security protection mechanism of multiple replicas and failure domains.

CDN is an application scenario with more reading and less writing. When writing data, storage distributes data slices evenly and redundantly to different hard disks of different servers; when reading data, it is read from the hard disks of multiple nodes at the same time, providing high-bandwidth and stable video stream. At the same time, in order to meet the needs of multi-concurrency at the frontend, the storage also comes with load balancing service to avoid network bottlenecks and stutters, thus ensuring a high-quality video experience.

IV. Income from the programme

L distributed data storage, flexible expansion and high reliability

Using decentralized distributed architecture, the storage capacity can reach above EB level.

Can be purchased on demand, capacity and performance increase linearly with the number of nodes

Multi-copy, multi-failure domain and other security mechanisms to ensure data security

When the hardware is abnormal, start the automatic and fast data reconstruction mechanism

L video optimization technology for faster video access experience

Large file data slice storage, providing multi-node, high-bandwidth and stable video stream

The storage node is expanded online, the performance output increases linearly, and the underlying data is distributed and balanced automatically.

Video traffic load balancing, supporting the concurrent reading of massive content at the front end

L video tag index, intelligent video processing

Built-in video intelligent processing engines such as video content analysis, content audit, intelligent production, etc.

Automatic video tag processing to retrieve videos more quickly and accurately

Support docking with big data analysis platforms such as Hadoop and Spark

High compatibility, perfect match with mainstream CDN platform

Using the standard S3 object storage protocol, it can be smoothly docked to the existing business system that supports S3 protocol.

Provides SDK toolkits for RESTFul API, console and multiple languages

Provide development support services to support the rapid transformation and launch of the VOD platform
