The past year has had a profound impact on the pace and direction of digital transformation of the global economy. As we approach the anniversary of life in the age of COVID-19, the ongoing effects on the data centre industry have only become more pronounced. “Thanks to an exponential increase in demand for content delivery in entertainment, education and commerce, 2020 saw a huge spike in demand for data,” says Brian Johnson, global data centre leader at ABB. With lockdowns continuing to require millions of people to work from home, as well as increasing our collective reliance on digital services, data centres have become increasingly essential pieces of infrastructure. “They’ve been crucial to keeping businesses going and people connected,” Johnson adds. 

The effects of the pandemic - twinned with the ongoing transformative influence of Industry 4.0 - have accelerated a global shift away from enterprise data centres towards the cloud. Over the past year, the data centre industry has split in two, as hyperscale and cloud platform providers have grown, and enterprise spending has fallen. With hyperscalers already scrambling to keep pace with growing demand, Johnson warns that the trend shouldn’t be expected to slow down this year. “It’s difficult to see this decreasing as we look ahead to 2021, as changes to the way we live, work and socialise are set to continue,” he predicts. “Greater connectivity brought about by advances in 5G, including the launch of new 5G compatible devices like the iPhone 12, and greater use of AI and machine learning, is also set to have a huge impact on data centres.”

As we enter 2021, Data Centre Magazine speaks with some of the leading figures in the data centre industry about emerging trends, challenges to be overcome, and the future of the cloud. 

Insatiable Demand

In a recent report, Gartner predicted that, after experiencing a 10.3% drop in 2020, data centre spending will rebound in 2021. This year, total investment in new and ongoing projects is expected to grow by 6% to reach more than $200bn. The majority of the decline in 2020, noted Gartner senior research director Naveen Mishra, is due to larger enterprise data centre sites “hitting pause temporarily,” before resuming in 2021. “However,” he added, “hyperscalers will continue with their global expansion plans due to continued investments in public cloud.” 

Sid Nag, research vice president at Gartner, noted in another industry report that, “The ability to use on-demand, scalable cloud models to achieve cost efficiency and business continuity is providing the impetus for organizations to rapidly accelerate their digital business transformation plans. The increased use of public cloud services has reinforced cloud adoption to be the ‘new normal,’ now more than ever.”

Keith Stafford, head of cloud architecture at Continent 8 Technologies, agrees with the assessment. With more than 60 data centres across Europe, APAC and North and South America, Continent 8 has experienced the global surge in cloud demand over the past 12 months, particularly driven by a spike in media consumption. “The use of public cloud services continues to grow,” says Stafford, noting that customers increasingly seek out the comprehensive services that the public cloud provides in order to increase agility and reduce OpEx, as well as gaining access to quick burst capacity in order to handle spikes in demand. 

The ability to help customers respond to these spikes in demand for data services has been a hallmark of 2020. Johnson notes that, “this demand for data has resulted in a real shift in several areas – data centres have had to become increasingly agile to respond to different demand peaks, while maintaining high levels of security and sustainability.” Across the board, however, increased digital transformation and technological innovation are continuing to mount pressure upon data centre operators; by 2026, 5G is expected to account for 54% of all mobile data traffic, reaching a total of 226 exabytes per month; the growth of the internet of things (IoT) is predicted to include 37bn connected connected devices by 2025; and the increased use of data centres for big data, artificial intelligence (AI) and machine learning based high performance computing (HPC) and quantum computing workloads. “And, as with all sectors, they have had to do this while its workforce adapts to new ways of working,” adds Johnson. 

Handling AI, IoT, 5G and HPC

In tandem with the ongoing search for a “new normal” amid the COVID-19 pandemic, the influence of 5G rollouts, IoT expansion, and increasing adoption of AI and HPC solutions across the digital economy have the potential to put immense strain on cloud service providers and data centre operators. 

“Content delivery networks are going to require more and more storage with the roll-out of 5G, and more network speed to avoid latency,” says Johnson. “We’ve seen TVs go to 4G, and YouTube is accepting 8G and 12G video already. Normal video is about 1G, so for every second that’s 12,000 times more information. It’s a tremendous amount of throughput, so the strain on the network will increase, and data centres will need to respond.” 

Data centre operators in 2021 and beyond won’t merely have to contend with the growing network load caused by 5G. According to Kevin Deierling, senior vice president of NVIDIA Networking, the effects of adopting the next generation of communications technology have the potential to be even more transformative. “Just like 4G spawned transformational change in transportation with Lyft and Uber, 5G will bring transformational new capabilities and business opportunities,” he explains. “It won’t happen all at once, but you’ll start to see the beginnings of companies seeking to take advantage of the confluence of AI, 5G and new computing platforms.”  

AI and HPC are also increasing the demands placed upon data centre operators, as increasingly complex IT loads are being moved to the cloud. Stafford notes that, so far, “the HPC Industry has been slow to embrace cloud,” adding that because “HPC Infrastructure is expensive, complex to setup and maintain, right sizing that environment is a difficult process.” However, he notes that cloud service providers have responded well to demand, and are starting to offer more solutions tailored to the HPC industry’s needs, like “investment in specialised hardware and solutions, which can be consumed in multiple options such as spot instances, reserved instances and hosts to better control costs.” 

Reaching Maturity

The pressures of the past year have thrown unprecedented challenges at consumers, enterprises alike. As data centre operators continue to respond and adapt to increased demand for data and cloud services in response to industry trends and the continuing pandemic, Johnson believes that the sector is reaching a new era of maturity. “As a result of our ever-increasing thirst for data, 2020 has seen a real maturing of the data centre landscape. It has grown from an ‘IT support system’ to an on-demand scalable service, a truly mission critical industry that enables economies to keep working and families to stay connected,” he says, noting that, while this is creating new opportunities for data centre and cloud platform operators, these exciting new developments will also generate their share of challenges, “particularly in protecting against cyber threats and managing the impact of digital infrastructure on our planet.” 

Stafford notes that, for all data centre customers, “moving to the cloud is a journey, not the destination.” Much like its customer base, the data centre industry is on a journey from the enterprise to the cloud. Bill Fenick, vice president of enterprise at Interxion: A Digital Realty Company, reflects that, “There is a firm understanding that cloud is the future for almost all enterprises,” adding that “There is no “one-size-fits-all” methodology – and indeed, a lot of trial and error.”

Tim Loake, Vice President, Infrastructure Solutions Group, UK at Dell Technologies highlights the importance of often-overlooked digital infrastructure

As the world retreated to a hybrid world in 2020, our reliance on technology took the spotlight. But it was the jazzy new social and video calling platforms that took the encore. Behind the scenes, our servers worked overtime, keeping us connected and maintaining the drumbeat of always-on newly digital services.  Let’s take a moment to pay our respect to the unsung technology heroes of the pandemic – the often-forgotten IT infrastructure keeping us connected come what may. After all, as we look ahead to more resilient futures, they will be playing a central role.

Servers could be likened to our plumbing – vital to well-functioning homes but rarely top of mind so long as it is functioning. Never seen, rarely heard – our servers do all the graft with little praise. But it is essential to reflect on the incremental advances in GPU and CPU power, which have paved the way for new workloads that previously were not possible. Chatbots and native language processing that provide essential customer touchpoints for businesses across the retail and banking sectors rely on powerful servers. They also keep businesses competitive and customers happy in an always-on world.

Serving workplace transformation

But, as businesses grappled with pandemic disruptions, the focus was largely on adopting connected devices – and awe at the rapid increase in the datasphere.  As they reined in their budgets and attempted to do more with less, one aspect was perhaps overlooked—those hard working servers.

When it came to building resilience into a newly remote workforce, the initial concern was focused on the device endpoints – keeping employees productive.  Many companies did not initially consider whether they had the server infrastructure to enable the entire workforce to log in remotely at the same time. As a result, many experienced a plethora of teething problems: virtual office crashes, long waits to get on servers, and sluggish internet connectivity and application performance, often rendering the shiny new PC frustrating and useless.

Most businesses only had a few outward-facing servers that could authenticate remote workers – a vital gateway as the vector for cyber hacks and attacks increased exponentially. That’s not to mention the fact that many business applications simply weren’t designed to work with the latency required for people working from home. What businesses discovered at that moment was that their plumbing was out of date.  

Business and IT leaders quickly realised that to stay ahead of the curve in the hybrid working world, a renewed focus on building agile, adaptable, and flexible IT infrastructures was critical. More importantly, it accelerated the inevitable digital transformation that would keep them competitive in a data-driven economy. It is now abundantly clear to businesses that they need IT infrastructure to meet the demands of diverse workloads – derive intelligent insights from data, deploy applications effectively, and enhance data management and security.  

Ripe for a digital revolution

Unsurprisingly, IDC noted that there was an increase in purchases of server infrastructure to support changing workloads. However, it also forecasts this uptick will be sustainable and last beyond the pandemic. As the economy begins to reopen, business leaders are looking ahead. IT will continue to play a crucial role in 2021 and beyond – and we have already set the foundations for the digital revolution with next-generation servers. 

As we enter the zettabyte era, new innovative technologies are coming on stream, with 5G turbocharging IoT and putting edge computing to work.  Exciting new services improved day-to-day efficiencies, and the transformation of our digital society will be underpinned by resilient IT infrastructures.  By embracing the technological innovations of our next-generation servers, businesses keep pace with the coming data deluge.

The next generation of server architecture promises more power with less heat, thanks to improved, directed airflow, and direct liquid cooling, resulting in reduced operational costs and environmental impact. As we rebuild post-pandemic, manufacturers and customers alike strive to achieve ever more challenging sustainability goals. With this in mind, a focus on environmentally responsible design is imperative for the servers of tomorrow -  uniquely designed chassis for adaptive cooling and more efficient power consumption will be critical, improving energy efficiency generation over generation.

The most notable evolution is the configuration of these next-gen servers around more specific organisational needs. Unlike clunky and often unstable legacy infrastructure, the infrastructure of tomorrow will be sturdier and more modular. The next iteration is streamlined, and in this modular form, can be more easily tailored to business needs. This equates to essential cost savings as businesses only pay for what they use.  

Resolving the problem of the future, today

Tomorrow's IT challenges will focus on response times and latency as Edge and 5G technologies go mainstream. As businesses develop new and innovative services that utilise supercharged connectivity and real-time analytics, staying on top of these challenges will give them a competitive edge. For example, in the world of retail, automation will power new virtual security guards and even the slightest delay in the data relay could result in financial loss. 

Similarly, in the smart cities of tomorrow, the network must be responsive. With city-centre traffic lights controlled by an AI-powered camera that monitors pedestrians, delays in data transfers could cost the life of an elderly pedestrian who has fallen in the road. The stakes are far higher in a 5G-enabled world. As our reliance on technology deepens, the margins for error narrow, placing greater emphasis on the efficiency of those critical underpinning technologies.

Fully enabling the hybrid work model today is just a stepping-stone towards more fluid, tech-enabled lives. A work Zoom call from an automated vehicle on-route to an intelligent transport hub is a highly probable vision of our future. But it requires incredible amounts of compute and seamless data transfers to make it possible. These glossy snapshots need super servers to come to life, making that IT plumbing glisten with next-gen innovation essential. Without exemplary server architecture, we risk future tech advances and the human progression that it enables.
