When Microsoft introduced its plan to construct an underwater datacenter, Lathish Kumar Chaparala was excited.

“During the initial rollout of Project Natick, I used to log on to their website and watch the live feed of the underwater camera that was mounted on the datacenter,” says Chaparala, a senior program supervisor on the networking workforce in Core Companies Engineering and Operations (CSEO), the engineering group at Microsoft that builds and manages the merchandise, processes, and providers that Microsoft runs on.

Little did he know that he and his workforce would later be introduced in to increase the community connectivity of this underwater datacenter so it could possibly be safely fished out of the ocean.

However the story begins a lot sooner than that.

We noticed the potential profit [of developing an underwater datacenter] to the business and Microsoft. Individuals responded to our work as if we had been going to the moon. In our eyes, we had been simply fulfilling our constitution—taking over difficult issues and developing with options.

– Mike Shepperd, senior analysis and growth engineer on the Microsoft Analysis workforce

The thought of an underwater datacenter got here out of ThinkWeek, a Microsoft occasion the place workers shared out-of-the-box concepts that they thought the corporate ought to pursue. One inventive thought was put forth by workers Sean James and Todd Rawlings, who proposed constructing an underwater datacenter powered by renewable ocean vitality that would supply super-fast cloud providers to crowded coastal populations.

Their thought appealed to Norm Whitaker, who led particular initiatives for Microsoft Analysis on the time.

Out of this, Project Natick was born.

“Norm’s team was responsible for making the impossible possible, so he started exploring the viability of an underwater datacenter that could be powered by renewable energy,” says Mike Shepperd, a senior analysis and growth engineer on the Microsoft Analysis workforce who was introduced on to assist analysis on the feasibility of underwater datacenters.

It rapidly grew to become a Microsoft-wide effort that spanned engineering, analysis, and IT.

“We saw the potential benefit to the industry and Microsoft,” Shepperd says. “People responded to our work as if we were going to the moon. In our eyes, we were just fulfilling our charter—taking on challenging problems and coming up with solutions.”

Researchers on the challenge hypothesized that having a sealed container on the ocean flooring with a low-humidity nitrogen atmosphere and chilly, secure temperatures would higher shield the servers and enhance reliability.

“Once you’re down 20 to 30 meters into the water, you’re out of the weather,” Shepperd says. “You could have a hurricane raging above you, and an underwater datacenter will be none the wiser.”

Inside engineering workforce steps up

The Undertaking Natick workforce partnered with networking and safety groups in CSEO and Arista to create a safe wide-area community (WAN) connection from the underwater datacenter to the company community.

“We needed the connectivity that they provided to finish off our project in the right way,” Shepperd says. “We also needed that connectivity to support the actual decommissioning process, which was very challenging because we had deployed the datacenter in such a remote location.”

Within the spring of 2018, they deployed a completely linked and safe datacenter 117 toes under sea stage within the Orkney Islands, simply off the coast of Scotland. After it was designed, arrange, and gently lowered onto the seabed, the purpose was to go away it untouched for 2 years. Chakri Thammineni, a community engineer in CSEO, supported these efforts.

“Project Natick was my first engagement after I joined Microsoft, and it was a great opportunity to collaborate with many folks to come up with a network solution,” Thammineni says.

Earlier this 12 months, the experiment concluded with out interruption. And sure, the workforce discovered that inserting a datacenter underwater is certainly a extra sustainable and environment friendly method to carry the cloud to coastal areas, offering higher datacenter responsiveness.

With the experiment ending, the workforce wanted to get better the datacenter so it might analyze all the info collected throughout its time underwater.

That’s the place Microsoft’s inner engineering groups got here in.

“To make sure we didn’t lose any data, we needed to keep the datacenter connected to Microsoft’s corporate network during our extraction,” Shepperd says. “We accomplished this with a leased line dedicated to our use, one that we used to connect the datacenter with our Microsoft facility in London.”

The extraction additionally needed to be timed excellent for a similar causes.

“The seas in Orkney throw up waves that can be as much as 9 to 10 meters high for most of the year,” he says. “The team chose this location because of the extreme conditions, reasoning it was a good place to demonstrate the ability to deploy Natick datacenters just about anywhere.”

After which, prefer it has for thus many different initiatives, COVID-19 compelled the workforce to alter its plans. Within the technique of developing with a brand new datacenter restoration plan, the workforce realized that the company connectivity was being shut down on the finish of Could 2020 and couldn’t be prolonged.

“Ordering the gear would’ve taken two to three months, and we were on a much shorter timeline,” Chaparala says.

Shepperd referred to as on the workforce in Core Platform Engineering, a division of CSEO, to rapidly rework the company connectivity from the Microsoft London facility to the Natick shore space, all whereas guaranteeing that the connection was secured.

The mission?

Make sure that servers had been on-line till the datacenter could possibly be retrieved from the water, all with out extra {hardware}.

“My role was to make sure I understood the criticality of the request in terms of timeline, and to pull in the teams and expertise needed to keep the datacenter online until it was safely pulled out of the water,” Chaparala says.

The stakes had been excessive, particularly with the analysis that was on the road.

“If we lost connectivity and shut down the datacenter, it could have compromised the viability of the research we had done up until that point,” Shepperd says.

A seamless collaboration throughout Microsoft Analysis and IT

To unravel this downside, the groups in Core Platform Engineering and Microsoft Analysis needed to align their imaginative and prescient and workflows.

“Teams in IT might plan their work out for months or years in advance,” Shepperd says. “Our research is on a different timeline because we don’t know where technology will take us, so we needed to work together, and fast.”

As a result of they couldn’t carry any {hardware} to the datacenter website, Chaparala, Thammineni, and the Microsoft Analysis workforce wanted to provide you with a community redesign. This led to the implementation of software-based encryption utilizing a digital community working system on Home windows digital machines.

It’s thrilling to play a task in bringing the best engineers and program managers collectively for a standard purpose, particularly so rapidly. As soon as we had the best workforce, we knew there was nothing we couldn’t deal with.

With this answer in tow, the workforce might lengthen the community connectivity from the Microsoft Docklands facility in London to the Natick datacenter off the coast of Scotland.

“Chakri and Lathish have consistently engaged with us to fill the gaps between what our research team knew and what these networking experts at Microsoft needed in order to take action on the needs of this project,” Shepperd says. “Without help from their teams, we would not have been able to deliver on our research goals as quickly and efficiently as we did.”

Classes discovered from the world’s second underwater datacenter

The research on Project Natick pays dividends in Microsoft’s future work, notably round operating extra sustainable datacenters that might energy Microsoft Azure cloud providers.

“Whether a datacenter is on land or in water, the size and scale of Project Natick is a viable blueprint for datacenters of the future,” Shepperd says. “Instead of putting down acres of land for datacenters, our customers and competitors are all looking for ways to power their compute and to house storage in a more sustainable way.”

This expertise taught Chaparala to evaluate the wants of his companion groups.

“We work with customers to understand their requirements and come up with objectives and key results that align,” Chaparala says.

Finally, Undertaking Natick’s story is certainly one of cross-disciplinary collaboration – and simply within the nick of time.

“It’s exciting to play a role in bringing the right engineers and program managers together for a common goal, especially so quickly,” Chaparala says. “Once we had the right team, we knew there was nothing we couldn’t handle.”
