Today, the Internet has become a large part of people's daily lives. We watch videos, play games, read the news, and shop on the Internet almost every day. In recent years, online education, teleworking, and online healthcare (or eHealth) have also been gaining popularity. Behind all these, Content Delivery Network, or CDN, is the technology that ensures fast delivery of diverse content to you over the Internet, even though you may be unaware of its existence or never paid much attention to it.

The core purpose of CDN is acceleration. Without CDN, any requested content must be fetched from the source site, typically leading to excessive latency. With CDN, that content, the audio files, video content, images, and applications; is cached on servers located in different geographical regions and is always fetched from the nodes closest to the users who are requesting it. By ensuring a minimum physical distance between you and the content caching server, CDN ensures your content loads faster. Your web pages load faster, and streaming video is less likely to hang.

The advantages of HUAWEI CLOUD CDN can best be described in three words: fast, accurate, and reliable.

Acceleration with HUAWEI CLOUD CDN: Fast

What makes HUAWEI CLOUD CDN so special? The answer lies in its huge number of edge nodes. HUAWEI CLOUD CDN has over 2,500+ edge nodes all around the world, in more than 70 countries and regions on six continents. HUAWEI CLOUD also has cross-continent Direct Connect resources and central CDN nodes in different regions. HUAWEI CLOUD was named one of the best CDN service providers during the APAC CDN Summit for its vast CDN bandwidths.

HUAWEI CLOUD CDN uses intelligent cache technology to cache customers' content on massive edge nodes. Users can access content from the nearest nodes. This significantly improves user experience by reducing latency.

Acceleration with HUAWEI CLOUD CDN: The Accurate Part

Internet users may access content from anywhere in the world, so it is hard for content providers to always be able to deliver content to their users from a node in their proximity. To make that possible, a dispatch system is required.

Global Server Load Balance (GSLB), Huawei's in-house CDN dispatch system, is able to select the most appropriate CDN nodes at an accuracy of up to 99%. This is made possible by a global IP library & big data platform, which receives real-time information about the load of each node in terms of traffic volume and number of connections, distance to users, response time, and more.

Based on such information, GSLB is able to redirect user requests to the nodes closest to users. This can significantly accelerate content delivery and also reduce network congestion, making Internet service providers' websites or streaming services more responsive to users.

Deployment of HUAWEI CLOUD CDN for website acceleration

Acceleration with HUAWEI CLOUD CDN: Reliable

Under extreme conditions, when its servers are under excessive pressure, for example, sudden spikes in traffic, an Internet service platform may become unavailable to users.

With CDN, the chance that happens can be reduced significantly. HUAWEI CLOUD CDN can provide sufficient bandwidth to help customers cope with unexpected spikes in traffic. The availability of HUAWEI CLOUD CDN is as high as 99.9%. When some nodes fail, other nodes automatically take over to continue servicing users.

One unique advantage of HUAWEI CLOUD CDN is its intelligent monitoring system. This system monitors the end-to-end performance of the network in real time, including details such as latency, packet loss rate, availability, and first packet time. This is to ensure that the network stays up and running in the face of demanding situations, such as high concurrency and frequent traffic bursts.

Fast, accurate, and reliable acceleration with HUAWEI CLOUD CDN is key to delivering a superior user experience. Security is another important consideration when it comes to your choice of a CDN service. A business-neutral CDN acceleration platform, HUAWEI CLOUD CDN includes advanced security features such as secure transmission over HTTPS and anti-leeching, safeguarding the continuity of web services.

HUAWEI CLOUD CDN is used by customers from a wide range of sectors, such as video streaming, cloud games, e-commerce, finance, healthcare, and government. Looking forward, we will continue to invest heavily in CDN services to serve global customers, so that together we can deliver content to Internet users around world, both speedily and safely.
