Overview
Cloud Content Delivery Network (CDN) is a service designed for accelerated delivery, ensuring nearby access for end users through the distribution of content to cache nodes deployed globally. This widespread network minimizes network jitters and latencies, ultimately enhancing download speeds, responsiveness, and the overall user experience.
Benefits
Massive Acceleration Resources
CDN boasts extensive acceleration resources spread across 70+ countries and regions, totaling over 160 Tbps in combined bandwidth. Supported by major players like China Mobile, China Unicom, China Telecom, and numerous smaller ISPs, it delivers stable and rapid acceleration services, enhancing service availability.
Intelligent Scheduling
Cloud utilizes its proprietary GSLB scheduling system, coupled with a distinctive network-wide real-time monitoring system, to precisely direct user requests to the most suitable access nodes, guaranteeing exceptional access quality.
Global Acceleration
Operates over 2,000 cache nodes throughout China in collaboration with major providers like China Mobile, China Unicom, China Telecom, and numerous smaller ISPs. These nodes collectively offer over 160 Tbps bandwidth, addressing issues related to high cross-regional access latency. Additionally, maintains over 800 nodes across 70 countries and regions outside Mainland China to further enhance its global accessibility.
Monitoring and Alarming
CDN offers extensive real-time monitoring solutions for access and origin-pull traffic, bandwidth, requests, hit rate, and specific status codes at a minute-level granularity. This provides a live overview of your CDN service status and aids in monitoring the status of origin servers. Customizable alarm policies can be set up in Cloud Monitor to ensure you are promptly informed about any business fluctuations.
Data Analysis
The Content Delivery Network (CDN) allows you to access a range of reports, including active IP statistics, distribution of user access regions, and ISP distribution via log streaming. Moreover, you can download access logs for tailored analysis purposes.
Ease of Use
Once the CDN is activated and your domain name is connected, you only need to include a corresponding CNAME record at your domain name service provider to enable acceleration. No further adjustments to your business are necessary.
Features
Access Control
You have the ability to establish access limits and create blocklists or allowlists for referrers, IP addresses, and user agents to prevent specific requests. A variety of timestamp-based hotlink protection rules are at your disposal to deter unauthorized usage of your resources and mitigate potential losses.
Cache Configuration
You have the ability to configure the cache expiration time for your content across various CDN nodes based on file type, directory, and path. This strategy effectively boosts the node hit rate and lowers the consumption of origin-pull bandwidth.
HTTPS Acceleration
Offers complimentary SSL certificates. You have the option to acquire a free certificate through us or opt for a preferred one from Symantec or GeoTrust, which can then be seamlessly deployed to CDN for HTTPS access. Once deployed, you can utilize functionalities like enforcing HTTPS redirection (301/302 redirection) and leveraging HTTP 2.0.
Monitoring and Alarming
Complete real-time monitoring is accessible for tracking traffic statistics, bandwidth usage, requests, hit rate, origin-pull failure rate, and specific status codes at the minute level. This capability assists in comprehending the CDN service status and enables instant monitoring of origin servers.
Purge and Prefetch
Once updates or deletions are made to the contents on the origin server, tasks to purge URLs/directories can be initiated either via the console or through open APIs. This action deletes cached resources across the entire network, ensuring users can access the most recent resources.
Log Download
By default, access logs for all domain names from the past 30 days are provided. These logs consist of 15 fields: request time, client IP, domain name, access path, bytes transferred, client location, client ISP, status code, Referer, response time, User-Agent, Range, HTTP Method, and HTTP protocol identification.
Scenarios
Static Content Acceleration
Download Acceleration
Audio and Video Demand Acceleration
Exclusive GSLB scheduling system accurately directs user requests to the most suitable cache node using high-QPS clusters. This ensures swift responses to large volumes of requests for static pages and images, minimizing access latency and enhancing user experience.
Exclusive GSLB scheduling system effectively directs user requests to the most suitable cache node, guaranteeing a swift and consistent download experience by preloading download resources onto all nodes ahead of time.
CDN’s robust global acceleration capabilities ensure the swift, precise, and dependable delivery of video content on websites to all users worldwide. When combined with Cloud Object Storage (COS) for storing extensive collections of image and video files, static CDN acceleration significantly reduces content loading times and enhances overall user experience.
