CDN, or Content Delivery Network, supports several types of services to enhance the delivery of web content and applications. These include:
Static Content Delivery: This involves distributing static files like images, CSS, JavaScript, and videos across multiple servers globally. This reduces latency and improves load times for users.
Example: A website with a global audience uses a CDN to serve its static assets from servers closest to the user, ensuring faster access.
Dynamic Content Optimization: Some CDNs can optimize dynamic content by reducing the response time from the origin server. This is achieved through various techniques like caching at the edge, TCP optimization, and smart routing.
Example: An e-commerce site uses a CDN to dynamically serve product pages faster to users worldwide, even if the content is generated in real-time.
Security Services: CDNs offer security features such as DDoS protection, SSL/TLS encryption, and web application firewalls (WAF) to protect websites from cyber threats.
Example: A financial services website uses a CDN’s DDoS protection to mitigate the impact of distributed denial-of-service attacks.
Video Streaming: High-quality video streaming is a core service of many CDNs, supporting adaptive bitrate streaming technologies like HLS and DASH to ensure smooth playback across different devices and network conditions.
Example: A streaming service uses a CDN to deliver live sports events with high-quality video and minimal buffering.
API Acceleration: CDNs can accelerate API calls by caching responses at edge locations, reducing the load on backend servers and improving response times for developers and end-users.
Example: A mobile app uses a CDN to cache API responses, speeding up data retrieval and enhancing user experience.
Global Load Balancing: Some advanced CDNs offer global load balancing services to distribute traffic across multiple data centers, ensuring high availability and reliability.
Example: An enterprise with a global presence uses a CDN’s load balancing to evenly distribute traffic across its international offices and data centers.
For businesses looking to leverage these services, Tencent Cloud offers a comprehensive suite of CDN solutions tailored to various needs, ensuring efficient content delivery and enhanced security.
