How Cloud Computing Is Turning Cities into Data‑Driven Smart Hubs

The most distant distance in the world is the traffic light and the traffic monitoring camera.

The distance from Yunxi Town to Silicon Valley is far shorter than the distance from Yunxi Town to Zhongguancun.

The gap between Haier and Lenovo is just one YunOS.

At the Yunxi Conference, Wang Jian, Chairman of Alibaba Group's Technical Committee, delivered two keynote speeches, repeatedly using the concept of "distance" to illustrate technology, data, and innovation.

Wang opened with a Hubble telescope image, emphasizing that all technological innovation is an exploration; the evolution of "Feitian" (Alibaba Cloud's core operating system) represents this spirit. He said, "We added a single innovation variable that enables us to do things we previously dared not attempt."

Discussing AlphaGo and Deep Blue, he noted that twenty years ago Deep Blue's computing power equaled a modern smartphone and was monopolized by a few companies, whereas today AlphaGo's vastly higher computing demand can be met by public cloud platforms like Alibaba Cloud, freeing computing power for everyone.

He claimed that Yunxi Town is geographically closer to Silicon Valley than to Zhongguancun because companies like HP and Intel have partnered with YunOS, while Lenovo in Zhongguancun lacks innovative drive. After announcing strategic collaborations with Sharp, Haier, and others, he said, "The distance between Haier and Lenovo is just one YunOS."

Full transcript of Wang Jian's speech:

Welcome all innovators to the Yunxi Conference. I laughed at a translation mistake earlier, realizing that what seemed like an error is actually true machine intelligence—machines can also surprise us.

After 2008, I returned to Hangzhou and joined Alibaba, focusing on turning data into socially meaningful value. My first attempt at a "data Olympics" during the Beijing Olympics failed, but it sparked my belief that technology innovation is an exploration.

Seeing a Hubble image reminded me of our ignorance; the light we receive started billions of years ago, before Earth existed. This vast unknown drives our need to explore, and technology innovation mirrors that journey.

I once hesitated to share a story, but a line from a book inspired me: "This is a cover design from the last century, pointing to the next century's future," which I attribute to Jack Ma. It reminded me that engineers at Alibaba often wear plaid shirts, symbolizing their focus on experience.

Hangzhou, with its historic roots and innovative spirit, exemplifies how old economies (like oil) evolve into new ones. Without the sediment of the past, there would be no future.

Our cloud platform "Feitian" began with the first line of code written after the 2009 Spring Festival. It now underpins modern cloud computing, providing the essential technology layer for innovation.

In Chinese mythology, Feitian is a deity of happiness and auspiciousness, representing our reverence for technology and the environment needed for its growth—Hangzhou's West Lake and rivers provide that setting.

Innovation is an ongoing evolution, not a single event. Over the past decade and the next, we added one innovation variable that liberates computing power, allowing anyone to use it for creative purposes, even in remote regions like Xinjiang and Tibet.

Today, anyone can leverage Alibaba Cloud's resources to achieve what once required a handful of companies. This democratization of computing power fuels further innovation.

Twenty years ago Deep Blue defeated a chess champion with computing power comparable to a modern smartphone; today AlphaGo defeats a Go champion with tens of thousands of times more power, yet that power is accessible to anyone via the cloud.

The key shift is that data now teaches machines, rather than humans programming them directly. This massive increase in computational capability, now affordable to individuals, has liberated creativity.

Artificial intelligence, robotics, and other trendy technologies are all enabled by this freed computing power. The real challenge is to nurture creativity, not be constrained by past monopolies.

Consider the most distant distance: before the internet, it was the poles; now it's people sitting together at a table, each glued to their phone. Companies like Uber emerged because the distance between drivers and passengers was too great.

The ultimate distant distance is between a traffic monitoring camera and a traffic light—both on the same pole but never connected by data. Bridging this gap requires a city‑wide data brain.

Modern cities need a massive data brain to coordinate infrastructure, beyond roads and utilities. Data must guide smart traffic lights, turning a simple idea into a monumental transformation.

To turn a camera's feed into actionable traffic‑light control, countless networks, departments, and enterprises must cooperate—much like passing levels in a video game.

China has nearly 600,000 traffic cameras, yet their data remains unused. If humans manually monitored them, over 1.2 million people would be needed to review a day's footage.

This realization drives us to rethink urban management, using data and AI to create smarter, more efficient cities.

Alibaba's technology has already helped a minority‑ethnic music website from Xinjiang and Fortune‑500 companies alike, acting as a crucial variable that enables innovation for everyone.

In summary, the past two decades have shifted from a few companies monopolizing computing power to anyone accessing massive resources via the cloud, empowering creativity and driving the next wave of AI and smart‑city development.
