In recent weeks, Facebook, Google, and Apple have announced a slowing of construction of major new data centres in the U.S. and Europe.
The problem, as it turns out, is not because construction is being ordered halted, or even due to a lack of IT equipment, but because other components of the supply chain like fibre optics, batteries, and racks are scarce, according to Rick Villars, vice president of data centre and cloud research at IDC.
“We’ve been talking to people who haven’t made public statements yet, but the supply chain is the problem,” he says. “They are not stopping because they want to, but they don’t have materials to finish. That’s important but not the same as shutting down or not finishing buildings under way.”
The bulk of data centre construction in 2020 is hyperscale providers – Amazon Web Services and Microsoft, etc. – and colocation providers like Equinix and Digital Reality Trust. Enterprise-owned data centre construction is minimal, he says.
And building a data centre is not done on a whim. These facilities are huge and run in the billions of dollars. Most of the data centres under construction now have been under construction for six to 18 months, Villars says.
He adds people are more unwilling to break new ground but even that is not cause for alarm because there's an over-abundance of capacity, so issues won’t show up until 2021 or 2022.
“There has been more data centre space built for cloud and colocation operators in the last three years than in all history,” says Villars. “They built enough capacity and 2020 wasn’t going to be a big year for construction anyway. There is space available and no shortage of bandwidth and capacity. Now if nothing is built in the next two years, then yes, that might be a problem.”
Villars said that in addition to all the new capacity, the new hardware is so much better than older gear that data centre operators are getting much more out of each square foot.
“In a new data centre, they can get three to four times as much assets in the same space compared to even a five-year-old enterprise data centre. The new capacity is more efficient so there is more cushion,” he says.
The bottom line is right now there is a good amount of capacity and if it is managed effectively, operators can accommodate changes in loads right now and going forward.
Japan is the exception
Japan has a healthy IT industry and the third-largest economy behind the U.S. and China, but it has yet to produce its own cloud provider on par with AWS or Alibaba. So American companies are looking at the country as a greenfield opportunity.
Earlier this month Equinix announced a $10 billion joint venture with GIC, a Singapore financing firm, to build three hyperscale data centres in Tokyo and Osaka for the world’s largest hyperscale cloud platforms. Equinix didn’t say which, but the big four cloud providers (AWS, Microsoft, Google, IBM) all use Equinix for extra capacity.
And its chief rival, Digital Realty Trust, has been working with Mitsubishi to finance and construct new data centres in Tokyo and Osaka as well.
So life goes on, such as it is in these strange times.
