As websites, applications, APIs, videos, software downloads, and other online services continue to grow, CDN has become an important infrastructure for improving access speed and stability.
Although traditional CDN services are easy to integrate, long-term usage also comes with some challenges:
- Traffic costs continue to increase as business grows;
- Nodes, routing strategies, and data paths cannot be fully controlled;
- Some businesses have requirements related to compliance, data security, or customization;
- Building your own CDN usually requires significant research and development investment.
Therefore, more and more enterprises, IDC providers, and technical teams are exploring self-built CDN solutions.
99CDN is a platform designed to help users quickly build their own CDN networks. It is not a traditional CDN traffic provider. Instead, it is a CDN infrastructure management system that allows users to deploy edge nodes using their own servers and build a private content delivery network.

What Is 99CDN?
Simply put, 99CDN provides a set of tools for building your own CDN infrastructure.
Traditional CDN model:
User purchases CDN service → CDN provider supplies nodes → Charges based on traffic usage or subscription plans
99CDN model:
User prepares server resources → Deploys CDN nodes → Manages routing and caching independently → Builds a private CDN network
For example:
If you have multiple servers located in the United States, Japan, Hong Kong, Singapore, and other regions, you can use 99CDN to centrally manage these nodes and distribute traffic based on user location, network quality, and other factors.
The final architecture becomes:
User request → Nearest node → Cached content → Faster access speed
For IDC providers, cloud service providers, or enterprises with large amounts of server resources, self-built CDN can provide greater control and improve resource utilization.
Main Features of 99CDN
1. CDN Node Management
99CDN allows users to add and manage their own edge nodes.
Node servers can be deployed in different regions, such as:
- Hong Kong, China
- Tokyo, Japan
- Los Angeles, United States
- Singapore
- Europe and other regions
Users can expand the number of nodes according to their business requirements.
After adding nodes in the management panel, the system generates installation commands. Running these commands on the node servers completes the deployment process.
2. Intelligent Traffic Scheduling
99CDN provides DNS and GTM (Global Traffic Management) capabilities.
Based on node health status, geographic location, and other information, user requests can be distributed to different nodes.
For example:
- Asian users access Asian nodes;
- European and American users access nodes in their respective regions;
- If one node fails, traffic can automatically switch to other available nodes.
Compared with simple DNS round-robin, self-built CDN provides more flexible traffic management capabilities.
3. Cache Acceleration Capability
99CDN supports caching features including:
- Slice Cache
- Multi-level cache back-to-origin
For large files, software downloads, videos, and other scenarios, caching mechanisms can reduce pressure on the origin server.
Typical architecture:
User ↓ Edge Node Cache ↓ Regional Node ↓ Origin Server
Through multi-level caching, the load on the origin server can be reduced while improving service stability.
4. Security Protection Features
CDN is not only responsible for acceleration but also provides certain security protection capabilities.
99CDN provides:
- WAF Web Application Firewall
- CC attack protection
- DDoS protection
- Hotlink protection
- Access authentication configuration
- Cross-origin resource sharing configuration
Different license versions may support different features. The free version is mainly suitable for testing and basic usage.
5. Commercial Operation Capabilities
For IDC providers and cloud service providers, 99CDN also provides features related to commercial operations, including:
- Multi-tenant management
- Package and plan configuration
- Billing system
These features allow providers to quickly build their own CDN service platform based on their existing server resources.
Who Is 99CDN Suitable For?
1. Enterprises with Large Websites and High Traffic Applications
Examples include:
- Video platforms
- Download websites
- Gaming services
- Image hosting platforms
- API services
For businesses with large traffic volumes, traditional CDN services may result in high costs. A self-built CDN can improve resource utilization and reduce long-term expenses.
2. IDC and Cloud Service Providers
If you own a large number of servers, you can use 99CDN to build your own CDN product.
For example:
Instead of only renting out server resources, you can add:
- CDN acceleration services
- Security protection services
- Enterprise network optimization services
This helps create additional business opportunities and revenue streams.
3. Enterprises That Require Control Over Data and Network Paths
Some enterprises need:
- Control over data transmission paths;
- Independent node management;
- Custom traffic scheduling strategies.
A self-built CDN provides greater control and flexibility.
