The Nordics are a hub for data centres, with Facebook and Apple setting up in Denmark and Amazon are joining the party in Sweden. Never far behind, Google have also bought a plot next door to Apple, so as not to feel left out.
But why here? And what even are data centres?
An Introduction to Data Centres
Data centres are basically the engines that power all the buzzwords you hear every day. The Internet of Things, AI, blockchain and lots of others all depend on data centres to work.
Data centres store all the data collected by, and necessary for, these futuristic-sounding processes and technologies. Think all of the data that companies and private individuals produce, through their processes, buying habits and a ton of other activities.
Whether it’s collected through your phone, tablet, computer or even refrigerator, every piece of data that is sent to the mysterious ‘cloud’ actually ends up in one of these places.
But it’s a lot of data.
Powerful Data Needs Lots of Power
Racks, servers, cables, cooling, UPS, switch gears – they’re all power-hungry components that are essential for building a large-scale data centre. So power hungry that their energy consumption calls environmental concerns into question.
Last year alone, data centres used more electricity than the UK’s total consumption, meaning a huge carbon footprint. Plus, this creates very expensive running costs per centre.
That’s what brings us, and data centres, to the Nordics.
The Great Green North
Scandinavia is admired all over the world for its adoption of renewable energy. 72% of the energy in Denmark comes from renewable sources and the remaining Nordic cousins are following suit. This means that, by powering your data centre in the Nordics, you’re not making quite as much of a dent in the ozone layer.
Data centres also kick out a lot of heat. Therefore, to cut down on cooling costs it makes sense to place them somewhere cold. Enter the Nordics again.
Taking it one step further and combining these two points, in Sweden, Interxion have even installed heat exchangers which take the excess heat from their centres and direct it into Fortum Värme (now Stockholm Exergi)’s district heating system. That represents a major win for both companies: Interxion keep their data centres cooler for a lower cost and Fortum get to use the recycled heat.
The Danes, and Facebook, are in on the action too. They’re also embracing heat recycling to heat a nearby neighbourhood to their Odense cloud campus.
This technology has enabled data centres and their respective companies to move from being seen as a drain on resources and environmentally damaging proposition to welcome neighbours.
It Just Makes Sense
With continued digitization across all industries and data centres’ energy use and proliferation forecasted to continue to grow, it’s imperative they’re in an accommodating place.
Throw in the fact that Scandinavia has some of the most reliable internet connections in the world and is the easiest place in Europe to secure construction permits and do business, it seems like it’s a no-brainer. Nordics it is everyone.
Smart tech has allowed the security and access control space to evolve greatly in recent years. I spoke with industry leader, Lee Odess, about what the future may hold for the space.
Smart cities are on the rise. But how do we keep them safe? How do we protect their cyber security? In this webinar, we’re joined by a panel of well-established cybersecurity leaders to answer these questions and more. Click to watch.
