This year’s Olympics recorded several firsts, including the first to postpone its schedule and the first to limit the number of spectators, and is destined to leave a special mark in Olympic history. However, in addition to the many firsts, China’s technological power has also made a historic breakthrough on a key track of this global sports event.
Alibaba Cloud supported the global live broadcast of the Olympic Games this year for the first time, marking an important step in the Olympics going digital. Technology was of paramount importance for this year’s Olympics, which coincided with the global COVID-19. We believe that this historic event will open an era in which more sports enthusiasts choose to “watch games on the cloud” as the primary way of enjoying international sports events.
Cloud-native Power Helps International Sports Events Go Digital
This was a true “Sports Event on the Cloud”. Alibaba Cloud not only provided a wealth of cloud computing resources including storage, computing, and networking to support core events in the games, but its container service also played a critical part, embodying a key trend in which the container is becoming a new interface for accessing resources on the cloud and the preferred method for global application deliveries. For example, the Alibaba Cloud Container Service for Kubernetes (ACK), the best container execution environment on Alibaba Cloud, and the Alibaba Cloud Container Registry (ACR), the best containerized application distribution infrastructure, were both driving international sports to evolve digitally by outputting cloud-native capabilities that feature efficiency and stability, extreme elasticity, security and intelligence.
Echoing the progress and transcendence embodied in the Olympic motto of “Faster, Higher, Stronger — Together”, ACK strives to deliver the very best capabilities. During this year’s widely viewed Olympics, Alibaba Cloud’s enhanced container service ACK Pro and container image service for enterprises ACR EE delivered impressive performance, while ensuring a robust base for creating and running upper-level applications, and demonstrating to the world China’s “cloud-native power”.
1. Alibaba Cloud Ensures Stable Operations of the Olympic Website
Each and every move of this Olympic Games fell under the spotlight due to the particularity of the timing and the huge challenges faced by the organizers. The official website of the games is the most authoritative platform for publishing real-time event information. Thanks to the high-availability, dual-active architecture of ACK Pro in Frankfurt, Hong Kong and other regions, the website delivered high performance and provided stable, reliable, and safe access from across the world throughout the period. Alibaba Cloud’s container technology has played a key part in guaranteeing timely updates schedules, events, athletes, and Olympic stories to the world.
2. Alibaba Cloud Provides Real-time Games Data Efficiently and Securely
Given the huge scale of the Olympic Games, it is no exaggeration to describe its data needs as “massive”. A huge database is the only solution to process such information efficiently. The database received information from event result reporting applications, collected information such as the event start time and the athlete’s performance for centralized processing, and then sent data to other applications.
The event database used ACK Pro to create a high-availability architecture supporting remote disaster recovery in multiple regions including Tokyo and Frankfurt, helping to ensure data security, business continuity, and comprehensive data protection for applications. In addition, the system has stringent real-time requirements to ensure real-time data collection, processing, and output. The excellent performance of ACK Pro and ACR EE fully met these real-timeliness requirements. Alibaba Cloud allowed nodes to expand rapidly and pods to respond to traffic bursts, thanks to ACR EE’s large-scale distribution of container images and ACK Pro’s extreme elasticity.
In addition, the rapid DevOps deployment capabilities of the container technology was leveraged in automatic media labeling to integrate data from different sources, such as athletes’ entry time and scoring time. This allowed databases to be established and the metadata related to OBS video images to be enhanced via AI. This project benefitted from ACK Pro during deployment and establishment to improve the automation of media labeling.
3. Alibaba Cloud’s Extreme Elasticity “Brings Olympic Village into the Palm of Your Hand”
Technology has enhanced the public interaction with the games via a diversity of novel and interesting online approaches, despite the strict limitation imposed on watching the games on site. For example, an Olympic-themed adventure mobile game launched by PinQuest allowed users to embark on their own “Olympic Village Adventure” on mobile phones. The game is supported by Alibaba Cloud Serverless Kubernetes (ASK), which brings extreme elasticity into key modules. It was initiated and quickly released more than 10 days before the event, fully demonstrating the rapid deployment and extreme elasticity of containers.
Rome was not built in a day. What enabled the extensive application and satisfying performance of container services at this year’s Olympics Games was Alibaba’s core technical capabilities, accumulated and honed during the cloud-native transformation for more than 10 years.

· Well-structured support pre-plan system
ACK developed a full-process support solution targeting the Olympic Games based on its existing support solutions, including pre-plans, contingency plans, fault drills, and duty scheduling. ACK has rich experience in providing support and its capabilities are constantly honed during annual events like the Double 11 shopping carnival, the 618 shopping carnival, and the Spring Festival Gala. These large-scale events entail complex and comprehensive tasks and ACK has recorded nearly zero failures supporting them.
Apart from the above major events, ACK also organizes regular chaos-based fault drills and surprise attacks internally. In such drills, faults are injected to the chaotic system randomly and the ACK team members on duty receive an alarm and handle the issue immediately according to plans in the system. Such regular training has tempered the team’s emergency responses and allowed them to meet the 1–5–10 objective (namely, issue the alarm within 1 minute, locate the fault within 5 minutes, and resolve the fault within 10 minutes). These support systems, which have been repeatedly honed through real-life combat, were applied to the Olympics support program thereby guaranteeing stable and smooth progress of the games.
Trends in Containerization and Global Application Delivery
ACK was deeply engaged in the support to this year’s Olympic Games, and delivered steady performance of core tasks associated with the official website and event data processing with its industry-leading cloud-native technology, products, and services.
