Overview

Cloud Live is an easy-to-use livestreaming service that provides diverse live acceleration capabilities for entertainment, e-commerce, and education scenarios.

It includes the following subservices:

  • Cloud Stream Live improves the stability and efficiency of high-concurrency livestreaming and provides powerful real-time media processing capabilities.
  • Low Latency Live (LLL), which is built on cutting-edge technologies such as transmission protocol optimization, dynamic routing, and low-latency transcoding, slashes live latency to milliseconds in latency-sensitive scenarios and delivers an unrivaled experience even when there are a massive number of concurrent requests.

For details about how to enable Live, see Quick Start.

Service Architecture (for Cloud Stream Live)

Process of livestreaming:

  1. A streaming tool is used to push a live stream to the Live center with uplink acceleration enabled.
  2. The Live center transcodes the live stream in real time as required.
  3. The processed live stream is distributed to viewers with downlink acceleration enabled.
  4. Live records the live stream to Object Storage Service (OBS).

Service Architecture (for LLL)

Features

Global acceleration

2,800+ nodes are deployed worldwide and provide a bandwidth reserve of more than 100 Tbit/s.

Ultimate experience

Supports tens of millions of concurrent requests. Huawei-developed congestion control algorithm and intelligent scheduling policy secure ultra-HD and smooth livestreaming, with a frame freezing rate lower than 1%. Low-bitrate HD transcoding is more suitable to human eyes-based subjective rate-distortion decision model and reduces the bitrate by 30% to 40% whereas the video subjective quality does not deteriorate.

High stability & reliability

Provides multi-center and cross-region cluster disaster recovery and 24/7 service support. The livestreaming architecture is built on Huawei's 20 years of Cloud Native 2.0 experience. It is an agile and intelligent architecture that combines enhanced security and reliability with fast scaling to safeguard your livestreaming.

Statistical analysis

Provides statistics about livestreaming, value-added services, and stream playback profiles. All access logs can be downloaded, facilitating service analysis and service development.

Demo

A multi-terminal demo is provided for you to try out LLL.

To obtain the app demo and source code, contact Huawei Cloud technical engineers by submitting a service ticket.

Offering pricing

By default, the fee is charged by downlink playback traffic. Currently, you can pay by traffic, daily peak bandwidth, or 95th percentile bandwidth. For details, see Billing.
