The cloud will not kill the data center, but it will transform it. That’s one of the takeaways from the 2020 State of the Data Center report from AFCOM, the industry association for data center professionals.
In the near term, construction will slow way down, which aligns with what IDC analyst Rick Villars told me about data center construction slowing after a big buildout. More than 60% of respondents to the AFCOM report said they have no plans to build a new facility in the next 12 months, although 53% said they’ll have at least one data center in the works over the next 36 months.
Only 16% of respondents expect to build two or three data centers over the next three years. On the topic of renovating or expanding data centers over the coming 12 to 36 months, respondents said an average of one or two data centers would be renovated, down from about four in last year’s report.
But that does not mean the end of the enterprise data center. Bill Kleyman, executive vice president of digital solutions at Switch and author of the report, wrote: “Although cloud will continue to play a key role in how we deliver core applications and services, it will not replace data center solutions. This is evident by the types of investments that major cloud providers are making in having their solutions run within your data center.”
Three of the big four U.S. cloud providers have software solutions to deploy in your data center and replicate the same experience as their cloud services – Google Anthos, Azure Stack, and AWS Outposts. IBM doesn’t quite have an offering, although with Red Hat under the IBM umbrella, I can’t see it not happening. For now there’s the IBM Cloud Integration Platform to help operate cloud services across cloud and on-premises environments under one secure operating model and toolset.
“Moving forward, we’ll only see a tighter integration between cloud and on premises solutions. Here’s another key point: the way we define hybrid and private clouds will change as well. If you’ve deployed AWS Outposts, technically, you’re running native AWS services in AWS managed gear onsite at your data center,” Kleyman wrote.
These privatized hybrid clouds will allow organizations that were once concerned or had reservations around cloud to continue to leverage their existing on-premises ecosystem, while coupling the power of a public cloud provider, Kleyman added.
Data center density increases, square footage shrinks
The report found that the average rack density increased significantly in just one year. Rack density hit 8.2 kW per rack in 2019, up from 7.3 kW in 2018 and 7.2 kW in 2017. About 68% of respondents reported that rack density has increased over the past three years, with 26% saying the increase was “significant.”
That’s not surprising as AI takes off across all industries. AI is very processor-intensive and uses specialized chips, along with FPGAs and GPUs, to crunch data.
However, Kleyman said by e-mail he didn’t know the exact cause. “We didn’t really ask ‘why’ this was happening, but we did notice the trend from last year,” he said.
The typical respondent to AFCOM’s survey said their operations currently cover an estimated median of 6,000 square feet, far less than reported numbers from last year and from previous reports. However, that footprint is expected to double within the next three years.
When speaking to a few of the respondents and members of the Data Center Institute board, AFCOM found a lot of leading data centers are working very hard to optimize space and density. “They’re trying to fill up the buckets they already have, instead of building out new space. Even at the edge, we saw rack density increase,” Kleyman said. “Our industry is seeing a bit of a consolidation effort. Again, trying to do more with less.”
