For decades, data centers have played a crucial role in the digital world, providing technology companies with a secure and powerful means of storing digital information on large-scale servers. Since their inception as early as the 1940s, these facilities have undergone profound transformations, adapting to shifting needs, whether to ensure their operational resilience or to align with evolving purposes for their establishment.

With this in mind, we must look back on their history and see how they have evolved and continue to do as they continue to be an integral part of our digital society as we advance.

The Early Days of Data Centers

The idea of a data center was first introduced in the 1940s. The first data centers were built for the Electronic Numerical Integrator and Computer (or ENIAC) was the world's first programmable computer developed by J. Presper Eckert and John Mauchly.

It was designed to calculate artillery fire during the Second World War by the U.S. Army and was even used by scientists and mathematicians on the Manhattan Project.

By 1947, Harry Truman saw the potential of this new technological achievement and worked with the CIA to assign researchers and engineers to assist in developing ENIAC technology and data centers across the country by the dawn of the Cold War. Secrecy of data centers has always been important, even today, but especially in their early days when they were government-owned and geared towards military and intelligence functions.

Data centers were designed to only have one door and window to keep them as secret as possible, large fans and vents were needed to keep them as cool as possible, and there were hundreds of feet of wiring sealed by vacuum tubes to connect everything.

While impressive at the time, they were still very primitive. The wiring would often fail and overheat, which could even lead to the spread of fires.

Computer technology changed by the 1960s and 1970s. International Business Machines (IBM) released their first transistorized computer called TRADIC, developed by Jean H. Felker in 1954, which helped data centers expand from the military sphere to the commercial, removing the need for vacuum tubes, as transistors replaced them.

In the space of 30 years, data centers had gone from only being government-owned intelligence hubs, to reaching into the commercial bubble. However, they would take off significantly with the introduction of the internet.

The Birth of The PC and the Rise of The Internet

The late 1970s saw the introduction of the first Personal Computer (PC), a class of microcomputers sold by large computer companies, but they would skyrocket in popularity by the 1980s. While some large technology companies, such as IBM, continued to build data centers to house supercomputers, computing largely moved out of back rooms and onto desks.

The 1990s however gave way to the birth of the Internet, which led to a boom in the number of data centers produced. Now it wasn’t just the government and technology companies that relied on data centers, it was almost every company that required internet access, leading to them being more essential than ever.

Internet data centers have many servers and cables from various telephone companies and network operators running through them. In case of any technical problems with the website, the data center operator can change the server or switch the connection supporting it to ensure that it runs smoothly. This is a significant advantage and a major selling point for these data centers.

When organizations outsourced the management of their websites to outside parties, the next step for many of them was to move their other data operations to a data center.

This process, known as colocation, involved either placing their servers at a provider's data center or renting server space from the provider to access and run some applications remotely, such as email, data storage, or backup.

This continued through the 1990s and took center stage in the 2000s as the internet continued to mature. As IT investments surged and new facilities proliferated globally during the dotcom boom, the rush to capitalize on the burgeoning trend was palpable. However, with the eventual collapse of the bubble, the data center sector bore the brunt of the fallout: a staggering 17 out of the 27 pan-European entities folded, leaving a landscape of decimation in their wake.

Although it dealt a massive blow, the downturn kick-started a virtualization revolution. This reduced data center power consumption, space, and cooling requirements by 80%.

Cloud Computing and Modern Data Centers

Cloud services have seen tremendous growth over the last decade. Major players include:

  • Microsoft
  • Google
  • Amazon
  • IBM
  • Oracle
  • SAP
  • Salesforce
  • Alibaba (based in China)

Amazon blazed the trail in the cloud services market through its subsidiary, Amazon Web Services (AWS). Offering Infrastructure-as-a-Service (IaaS) solutions to businesses, AWS enables remote access to servers via the cloud, on-demand. This service caters to businesses' diverse data processing and management needs, providing a flexible and scalable solution.

The expansion of cloud data centers gained momentum when businesses began accessing their crucial software applications remotely through the cloud, rather than installing and maintaining them on servers at their premises (known as on-premises).

This transition was incentivized by the prospect of reduced software expenses, adaptable to fluctuating business requirements – a more cost-effective alternative compared to permanently installing feature-rich software on company servers onsite, where higher fixed costs are incurred.

Data centers have since grown to accommodate the increasing demand for cloud services. These large-scale facilities, known as hyperscale data centers, are owned by both cloud service providers and other companies that rent out the space to the well-known brands that offer these services.

Challenges and Looking to the Future

Amidst the ongoing advancements and technological innovations that have bolstered the data center industry, numerous areas for improvement exist to better align with the evolving needs of our changing world, particularly in the realm of sustainability where more eco-friendly solutions are increasingly imperative.
