Why choose DCDN
As online services expand globally, they face increasingly complex challenges to user experience and data security. DCDN provides an integrated platform that combines acceleration, computing, and security to protect and grow your business.
Accelerate dynamic and static content delivery
As your user base grows globally, long-distance data transfer, inconsistent network quality across regions, and network congestion can slow your website or application, causing timeouts that degrade the user experience.
DCDN provides faster, lower-latency access, creating a more immersive experience that drives user engagement and conversion.
Bring content closer to users
DCDN caches static content, such as images and videos, on over 3,200 globally distributed POPs. This allows users worldwide to access your services from the nearest POP, reducing content delivery time.
Use intelligent data routing
For dynamic content such as API calls, IoT device data transfers, and real-time gaming data, DCDN provides intelligent routing. This feature continuously monitors network quality across its 3,200+ POPs and calculates the optimal path for each request, improving the user experience.
For more information about dynamic and static resources, see What are static content and dynamic content?
Support a wide range of transmission protocols
DCDN supports Layer 7 acceleration for HTTP, HTTPS, and WebSocket, as well as IP Application Accelerator (IPA) for TCP and UDP. Its adaptive acceleration policies ensure efficient transmission routes.
Accelerate virtually any workload
DCDN integrates rapidly with almost any online service, delivering faster transmission speeds and lower latency than accessing the origin server directly. For more information about the acceleration performance of DCDN, see DCDN synthetic monitoring data.
Drive innovation with edge computing
As Internet services become more complex and diverse, dynamic requests such as search results and personalized recommendations account for a growing share of traffic. This diverse content requires computation before it can be returned to users.
DCDN lets you run computations at POPs, preventing origin server overload. This reduces concurrent connections and requests to your origin, smooths out traffic patterns, and lowers bandwidth costs. DCDN deploys edge computing services on its POPs, providing the following capabilities for customizing request handling worldwide.
Global Deployment and Ultra-Low Latency
DCDN moves computation from the origin server to its POPs, reducing physical link latency by more than 50%. By processing client requests close to their source, DCDN significantly reduces response times and delivers a low-latency computing experience.
Use the efficient and easy-to-use Serverless model
The Serverless platform automatically allocates sufficient computing and storage resources, freeing you from managing the underlying server infrastructure.
Focus on developing your business logic and deploy your application by publishing code to edge programs worldwide, reducing development costs.
Benefit from elastic scaling
When client requests surge in a region, DCDN quickly spins up nearby computing resources and automatically handles scaling and scheduling.
Secure your application with end-to-end protection
As businesses digitize, they face an increased risk of attacks. Data breaches and other security incidents can lead to compliance violations and business losses.
DCDN provides integrated security services at its POPs to filter and block malicious traffic close to its source. You can enable edge security features with a single click in the console to protect your websites, APIs, and applications.
Ensure end-to-end data security
DCDN provides comprehensive and reliable security for your data. You can configure features such as SSL certificates, referer-based hotlink protection, URL signing, and bot management to protect your data from network attacks. For more information, see Enable edge security.
Use edge WAF protection
Deploy a Web Application Firewall (WAF) on POPs to identify and mitigate malicious traffic, ensuring that only scrubbed traffic is routed back to your origin server. The edge WAF supports features such as an IP whitelist, a blacklist, a region blacklist, and bot management, as well as custom policies for fine-grained access control and rate limiting. For more information, see Overview of WAF.
Leverage edge DDoS mitigation
DCDN integrates DDoS mitigation into its POPs. Upon detecting a DDoS attack, DCDN automatically reroutes traffic from the acceleration service to the DDoS mitigation service. After the attack subsides, it automatically switches clean traffic back to the acceleration service. DCDN intelligently identifies Layer 3, 4, and 7 DDoS attacks, leveraging a global defense network with terabits-per-second (Tbps) capacity. For more information, see Mitigation settings.
