Dynamic Content Delivery Network (DCDN) accelerates dynamic and static content through 3,200+ global POPs, with integrated edge computing and security.
-
Acceleration
DCDN delivers content through 3,200+ global points of presence (POPs). Built onAlibaba Cloud CDN, DCDN integratesedge computing and security for end-to-end acceleration of both dynamic and static content.
-
Edge computing
Deploy code on DCDN POPs to process requests closer to users, reducing latency, offloading the origin server, reducing business fluctuations, and lowering bandwidth costs.
-
Security
Enable DDoS mitigation and Web Application Firewall (WAF) on POPs to block attacks before they reach yourdata centers, protecting websites,APIs, and edge applications. DCDN also provides SSL certificates and access control for data protection.

Architecture
DCDN architecture overview.
Intelligent content acceleration
When you add domain names to DCDN, it classifies requested content as static or dynamic and applies the appropriate acceleration policy.
-
For static files, requests are typicallyserved from the nearest POP. On a cache miss, DCDN fetches the content from the origin, caches it, and serves it to the user.
-
For dynamic content, DCDN uses smart routing to find the optimal path to the origin, retrieves the content, and delivers it to the user. Persistent connections are maintained between POPs and the origin server and between individual POPs, further reducing the time required to retrieve dynamic resources.
Intelligent and elastic edge computing services
Deploy services or lightweight applications (routines) on POPs for edge processing. Client requests are routed to the nearest POP, where routines handle them with minimal latency.
Edge security
Edge WAF and DDoS mitigation on POPs filter malicious requests and forward only legitimate traffic to the origin server. WAF protects web servers against intrusions, secures important business data, and prevents server anomalies caused by attacks.
Scenarios
Gaming
DCDN suits web-based games and multiplayer online battle arenas. In addition toroute optimization and caching, DCDN provides security services.
E-commerce
DCDN accelerates the images and text on e-commerce pages. Its edge computing capabilities render pages on POPs instead of on the origin server or client, improving response time and page load speed.
With global POP coverage, DCDN reduces response times by over 50%.
Finance
Financial services require high availability and strong security. Transactions are dynamic and interactive processes, and are vulnerable to attacks if performed over unsecured cross-network connections. DCDN edge WAF and DDoS mitigation safeguard every transaction.
