Introduction to the
The full name of Ali Cloud CDN is Alibaba Cloud Content Delivery Network. It is a distributed Network composed of edge node server clusters distributed in different regions, which is established and covered on the bearer Network. Replace the traditional WEB Server – centered data transmission mode.
Publish source content to edge nodes, with precise scheduling system; Allocate the user’s request to the most suitable node for him, so that the user can get the content he needs at the fastest speed, effectively solve the Internet network congestion, improve the response speed of user access.
Function is introduced
Node cache
Intelligent object heat algorithm, layered Cache of HOT resources, precise acceleration of resources High-performance Cache Cache system design, balanced use of CPU multi-core processing capability, efficient and rational use and control of memory, and maximum SSD IOPS and throughput Each node provides high-speed READ/write SSD storage. Sharply reduce user access latency, and improve the usability of intelligent compression, effectively reduce user transmission content size, speed up page optimization distribution effect, remove the page Spaces, newlines, tabs, annotations, such as redundant content, reduce page size combination of multiple JavaScript/CSS file as a request, thus reducing the number of requests accurate scheduling
No matter your site belongs to portal information website, multimedia video and audio website, game website or mobile application APP and so on, CDN will intelligently allocate scheduling domain to provide business support for your needs, comprehensively improve the speed of your site
Independent research and development of the dispatching system, single support millions of level domain scheduling more excellent controllability, protocol scalability, further reduce the cost Support multi-level scheduler, node failure will not result in the user, not with multiple system linkage, and security defense system, refresh coordinating system, content management system, etc Digital real-time scheduling, supporting node level traffic prediction, Improved scheduling quality and accuracy Multi-scenario service support and multi-component service
Live streaming media service, storage media assets, sliced transcoding, access authentication, content distribution to accelerate the integration solution (soon) audio gradual on-demand service, low buffer time, high fluency experience, supports mp4, FLV video format Links to support resources, customizable authentication KEY, ensure the security of your media resources, Natural seamless cooperation with the use of object storage OSS, improve website access speed, effectively reduce the cost of OSS external network traffic. Combined with the use of cloud server ECS, improve website availability and protect server source information. To reduce the bandwidth usage cost, load balancing can be used as the source address return source to reduce the bandwidth pressure of the return source. At the same time, non-Ali cloud source sites are supported. There is no threshold for docking, and after resource review, rapid deployment can accelerate self-service service management
Self-service console with customized configuration Minute-level intelligent deployment of all nodes You can quickly enable the CDN service with simple operations. You can configure the domain name add, delete, change, search through the console self-service, set the accelerated node cache policy, anti-theft chain, HTTP header information, etc., can also selectively open a variety of accelerated optimization functions according to the needs of open atomic extensible API. Through CDN API, the accelerated domain name, resource distribution and monitoring data can be flexibly deployed, quickly operated, accurately used and monitored in time. It can also cooperate with apis of other Aliyun cloud products to achieve real-time monitoring of customized Portal on multiple platforms
Panoramic information monitoring, multi-dimensional escort resource distribution Comprehensive network monitoring, rich data analysis, convenient download of resource reports, provides panoramic monitoring information including bandwidth traffic, access quality, visitor data, popular analysis, and security protection

Ali Cloud CDN use tutorial
(CDN can distribute the content of the source station to the node closest to the user, so that the user can obtain the required content nearby and improve the response speed and success rate of user access. Solve the problem of access delay caused by distribution, bandwidth, server performance, suitable for site acceleration, on-demand, live and other scenarios.
