From acquiring land to securing power supply, building data centres globally is a detailed operation.

“I seems like it’s effortless and it’s not,” Amazon Web Services vice-president of global data centres Kevin Miller told Markets with Madison in Las Vegas.

“There’s a lot of effort every day, adding network capacity, adding data centre capacity, bringing in more servers.”

Amazon was one of three hyperscalers, alongside Microsoft and Google, who together held most of the data centre market share globally.

They had been building hundreds around the world for almost 20 years, with  opening last week and Amazon’s due to open next year.

It builds them out in regions – which could be a city or a country. For example, New Zealand is a single region for Microsoft and Amazon.

Each region has availability zones within it, which house one or more data centre.

The regions were all connected by thousands of miles of fibre optic cable touching more than 20 countries.

Data centres could use between two and 60 megawatts of energy annually, and that was always taken from the grid, Miller explained.

However, Amazon and other hyperscalers were investing significant amounts into the development of nuclear energy to power their centres internationally.

“We see a lot of opportunity with that new nuclear and the next generation of nuclear reactors.”
