Elevate Live Streaming with Alibaba Cloud's Real-Time Streaming (RTS)

This article introduces Alibaba Cloud's Real-Time Streaming (RTS) and highlights its features and capabilities in the world of livestreaming.

In the dynamic world of livestreaming, where user experience is paramount, Alibaba Cloud's Real-Time Streaming (RTS) emerges as a game-changer. Leveraging the power of Web Real-Time Communication (WebRTC) and the robust infrastructure of ApsaraVideo Live and Alibaba Cloud CDN, RTS offers low latency, high concurrency, and efficient deployment, setting new standards in the livestreaming landscape.

The Need for Real-Time Streaming

Livestreaming has become a cornerstone in various commercial sectors, demanding a robust technological solution to provide an unparalleled user experience. Alibaba Cloud recognized this need and developed RTS, a leading interactive streaming feature based on the User Datagram Protocol (UDP), specifically designed to meet the challenges of modern livestreaming.

Low Latency for Enhanced User Experience

One of the standout features of RTS is its remarkably low latency. In comparison to traditional Flash Video (FLV) streaming, which typically incurs a latency of around seven seconds, RTS slashes this to a mere two seconds—a remarkable 70% reduction. This reduction in latency ensures a seamless and real-time engagement for users, enhancing the overall livestreaming experience.

High Concurrency with Global Reach

RTS boasts support for tens of millions of concurrent streams, tapping into the extensive network of over 3,200 CDN nodes worldwide. This, combined with ample reserved bandwidth and intelligent scheduling capabilities provided by Alibaba Cloud CDN, ensures that RTS can handle high levels of traffic with ease. The global reach of RTS makes it an ideal solution for livestreaming events of any scale.

Efficient Deployment Without Architectural Changes

Deploying RTS is both seamless and efficient. Users can integrate RTS into their ApsaraVideo Live service without the need for significant architectural changes. The compatibility of RTS with stream ingest, transcoding, and snapshot features of ApsaraVideo Live ensures a smooth and hassle-free deployment process. Additionally, updating the player SDK allows users to leverage the benefits of RTS without disrupting their existing infrastructure.

Real-World Success: Double 11 Global Shopping Festival

The practical prowess of RTS was demonstrated during Taobao's livestreaming at the Double 11 Global Shopping Festival. Alibaba Cloud's RTS played a pivotal role in ensuring a smooth and engaging livestreaming experience during this high-profile event, showcasing its reliability and effectiveness on a global stage.


Alibaba Cloud's Real-Time Streaming is shaping the livestreaming landscape, offering a winning combination of low latency, high concurrency, and efficient deployment. As the demand for immersive livestreaming experiences continues to grow, RTS stands as a testament to Alibaba Cloud's commitment to providing cutting-edge solutions that elevate user engagement to new heights. Whether for large-scale events or everyday livestreaming, RTS is poised to redefine the standards of what is possible in the world of real-time streaming.
