Reliable CDN Services for Hundreds of Thousands of Enterprises Worldwide
Originating from Taobao CDN, Alibaba Cloud CDN has been providing acceleration services for high-traffic e-commerce websites since the Double 11 in 2009. It was first applied and practiced in multiple e-commerce scenarios. Nowadays, Alibaba Cloud has established hundreds of high-quality nodes around the world and possessed excellent bandwidth resources.
In 2011, CDN, as a tool to distribute Internet traffic, was gradually applied to the entire Alibaba Group ecosystem, rather than just the Taobao e-commerce. In 2014, Alibaba Cloud CDN officially announced its commercialization and opened its service capabilities to global enterprises and entrepreneurs. In 2015, Alibaba Cloud CDN joined hands with e-commerce to enter the HTTPS era, and continuously upgraded its in-house scheduling system to cope with the exponentially growing traffic impact.
With the development of mobile Internet, the popularity of video services, and the practice of Double 11 every year, CDN traffic is growing exponentially. In 2017, Alibaba Cloud CDN launched its globalization strategy and successively released products such as Software Defined Cloud Networking (SDCN) and Dynamic Route for Content Delivery Network (DCDN). The product matrix was comprehensively upgraded. At the beginning of 2018, in the Market Guide for CDN Services published by Gartner, Alibaba Cloud was identified as a global service provider for its global service capabilities and technical advantages.
In recent years, Alibaba Cloud CDN has been continuously working on its product technologies around “intelligence” and “computability”, and has continued to improve its Serverless, multi-dimensional load balancing features for workload, scientific decision-making in various edge application scenarios. As a result, Alibaba Cloud CDN has won customers’ trust for its high-efficiency service and high-quality user experience. As the application of Alibaba Cloud CDN increases, the peak traffic scale of CDN has kept breaking its record.

Alibaba Cloud CDN has also built an ecological network to connect end-users around the world. During late peak hours, the network processes hundreds of millions of connection queries per second (QPS) and delivers billions of configuration management directives to all nodes every day.
Comprehensive and Professional CDN Best Practices for Industry Applications
With hundreds of thousands of enterprise customers on the cloud, the rich ecosystem applications of Alibaba, and a global infrastructure network, Alibaba Cloud CDN has been widely used in multiple scenarios, such as entertainment, e-commerce, games, sports, finance, governments, and enterprises.
During the 2018 World Cup in Russia, CDN hosted 70% of the network-wide traffic and supported 24 million times online watching on Youku. During the Double 11 in 2019, Alibaba Cloud CDN provided an excellent viewing experience of 4K and a frame freezing rate of less than 2% to 51.44 million audience.
At the same time, CDN also ensured a good e-commerce interactive experience during the traffic peak of tens of millions of QPS. In the first half of 2020 when the outbreak of Covid-19 urged the explosive growth of Internet services, Alibaba Cloud CDN enabled online office and online education by promoting DingTalk video conferencing, a national cloud platform for primary and secondary education, and VIPKID (an online teaching platform) to ensure a smooth, real-time, interactive watching experience. As thus, Alibaba Cloud CDN ensured continuity in education and work for hundreds of millions of people, initiating the era of online real-time video interaction.
Under the background of accelerated digital transformation in the post-epidemic era, Alibaba Cloud CDN is aimed at helping customers in finance, media, government, and enterprise industries resist the risk of cyber attacks and ensuring highly available, secure, and qualified online services. To this end, Alibaba Cloud CDN combines its rich practical experience on government cloud and financial cloud to customize a secure acceleration solution for government and enterprise. For example, media companies, such as CCTV.com, apply multiple CDN encryption modes for transmission to protect content from hijacking and tampering over the comprehensive process. Also, the content security and encryption techniques help improve the security of copyrighted video programs during transmission and playback.
In addition, with its excellent performance, core video technology, and rich practical experience, Alibaba Cloud CDN has guaranteed the live streaming of multiple major events, such as the New Year’s Eve, the Spring Festival Gala, the Asian Games, the League of Legends World Championship, the CBA, the World Artificial Intelligence Conference 2020, and the Double 11 every year.
Years of experience and development have made Alibaba Cloud CDN the mainstay of its own field. Currently, with the emergence of 5G and IoT technology, as well as the digital transformation, the feature of CDN will evolve from content delivery to value delivery, making CDN a powerful driving force for enterprises to improve efficiency, optimize operations, and achieve intelligent applications. In this situation, the map of the best practices of CDN can be the best assistant for millions of enterprises to deliver content and value, promoting innovation and development in more emerging industry scenarios.
