CTOs have traditionally been key positions for research-driven software and technology companies. As colocation companies increasingly move beyond merely serving space and power, the role of the CTO becomes more important.   Holland Barry, Field CTO for Cyxtera, discusses the role of the CTO and Field CTO at the company, the key skills required, and some of the interesting projects the company is working on. We also discuss the wider skills market and the shift from ‘dumb colo’ to service provider, and get a boots on the ground view of Cyxtera’s journey to becoming a public company via a SPAC merger.

DCD's Sebastian Moss talks to Doug Madory, the director of Internet analysis at Kentik, about the developing situation in Ukraine and Russia. We discuss telco disruptions, misinformation, false BGP hijacks, Cogent and Lumen's disconnection claims, whether Russia could drop off from the Internet, and more.

Data center automation is one thing, but what about automatons walking in the data halls? Robots in the data center are often discussed but rarely make it beyond the pilot project stage. Those that are deployed are often closer to Short Circuit’s Johnny 5 than Neill Blomkamp's CHAPPiE. Utah-based Novva data centers has deployed Boston Dynamics' Spot robot dog – possibly the most advanced robot that is currently commercially available – at its flagship data center and is looking to create a replicable and scalable model for deploying robots in its other current and future facilities. DCD discusses the pains of deploying a robot that is still a way off enterprise-ready plug-and-play with CEO Wes Swenson along with the lack of a wider support ecosystem for robotic deployments, and the future role of humans in the data center.

Figures quoted in 2021 suggested that data centers and communications technology could use eight percent or even 20 percent of the world's electricity by 2030. That seemed too high to us, so we tracked down the original source of the quotes, only to find he feels the same way.  Anders Andrae is an academic, currently working at Huawei's Swedish R&D center. Since his original 2015 paper he has revised his predictions down, but the old figures still often show up out of context.  More importantly, he thinks we should be looking at the benefits of IT as well as the energy cost. He talks of a "handprint" that counter-balances the environmental "footprint".  Andrae says the Internet saves far more emissions, through offering a digital alternative to physical services, than it consumes.

Data centers are about as efficient as they ever can be, in terms of delivering power to servers and keeping them cool, so what's the next step to sustainable digital infrastructure?  There is a lot of talk about reusing the wasted heat that facilities produce, but this seems like a hard job when all too often they can't give it away for free. Max Schulze is the founder of the Sustainable Digital Infrastructure Alliance (SDIA), a group of stakeholders aiming to achieve a sustainable digital infrastructure by 2030. He thinks the answer to heat reuse is economics, not engineering. And when we've sorted that out, he foresees that the big cloud providers will be disaggregated, and the cloud will become the same kind of market as the electricity grid.

In the first episode of the Zero Downtime podcast, we sit down with Lex Coors, winner of DCD's 2021 Outstanding Contribution to the Industry award and Chief Data Center Technology & Engineering Officer for Interxion. We spoke to Lex about his two decades at the company, from the early days, to the rise of cloud, and the recent Digital Realty acquisition. We also discussed sustainability efforts, the European energy crisis, and how to ensure that local communities don't turn against data centers.
