Data centers have become one of the most controversial topics in the technology sector with the massive boom in artificial intelligence usage. Services like ChatGPT and Google Gemini rely on them to run their models and process user requests, but data centers didn't emerge with AI; rather, they date back to the early decades of the computing era when mainframes occupied entire rooms. These facilities gradually evolved into large buildings and complexes that manage vast amounts of data and digital services.

What are data centers?

A data center is a physical facility that houses computer infrastructure that operates 24/7, including servers, storage systems, networks, cooling equipment, and power supplies. These facilities have robust backup power sources to keep devices running even in the event of a local power outage, as well as high-capacity internet connections that allow for the transfer of large amounts of data.
Data centers are used to store, process, and transmit various types of data, from email messages and credit card transactions to cloud storage services and cybersecurity software. They also handle user requests on AI robots.

The beginning... Mainframe computers in the 1950s and 60s

The first models of data centers emerged with early computers in the 1950s and 60s. The mainframe was almost the first image of a data center, a large computer capable of performing complex calculations that often required an entire room to accommodate it. At that time, modern computer networks had not yet appeared, so each mainframe operated almost independently, which could be considered a separate type of data center.
Over time, these systems grew in size during the 1970s and 80s, but the real shift in how data centers operate began with the emergence of microprocessors and the spread of the Internet in the 1990s.

The 1990s... The birth of virtualization

The 1990s saw the emergence of virtual simulation technology, which allowed a single physical device to create several virtual devices or servers. Instead of dedicating an actual device for each task, it became possible to run a cluster of virtual servers or networks on the same infrastructure. By the turn of the millennium, virtual servers were available for rent at more affordable prices, leading to a significant increase in demand for data centers.
Virtualization helped strengthen a more centralized model of computing, where vast numbers of devices and users relied on a relatively small number of data centers to provide various services.

From Microprocessor to Cloud and then AI

The evolution of data centers has always been linked to the technology that requires its computing power. At first, there was the microprocessor boom, then came the cloud computing surge, and now we are witnessing an artificial intelligence (AI) revolution. With each new technological wave, users’ expectations have risen and the amount of required computing has increased, forcing data centers to expand from small rooms to huge buildings and entire complexes that house a massive number of servers. As such, today's data centers are larger and more visible in their surrounding communities than they were decades ago.

Data Centers Are Not Just for AI

Although AI is one of the biggest sources of demand on data centers, it is not the only use for these facilities. To this day, there are different types of data centers, each with its own functions and needs. The Telecommunications Industry Association (TIA) divides data centers into 4 tiers that all provide essential services such as electricity and cooling around-the-clock. However, reliability, redundancy, and the ability to operate during outages increase with higher classification. At Tier 4, systems rely on independent power systems capable of continuing operation even in the event of major disruptions.

Telecommunications Data Centers

There are data centers dedicated to supporting telecommunications networks, including internet services and mobile phone networks. These facilities process the vast amounts of data that travel daily through communication networks, making them an essential part of modern internet and communications infrastructure.

Enterprise and Bank Data Centers

There are also enterprise data centers, owned and managed internally by specific entities such as banks, hospitals, and large corporations. This is because these entities handle highly sensitive data, requiring high levels of security and control over infrastructure and data.

Cryptocurrency Mining Centers

Another type of data center is focused on cryptocurrency mining. These centers rely on large amounts of computing power to perform the required operations in digital currency networks, making them energy and computing consumers within the data center sector.

مراكز بيانات الذكاء الاصطناعي.. أحدث أفراد العائلة

أما مراكز بيانات الذكاء الاصطناعي فهي أحدث نوع رئيسي ضمن هذه المنظومة، وتنقسم بدورها إلى نوعين أساسيين:
مراكز تدريب الذكاء الاصطناعي Training AI Data Centers، التي تركز على تدريب النماذج من خلال معالجة كميات هائلة من البيانات.
ومراكز استدلال الذكاء الاصطناعي Inference AI Data Centers، التي تتولى تشغيل النماذج بعد تدريبها والتعامل مع طلبات المستخدمين في الوقت الفعلي.
وهذا يوضح أن ظهور الذكاء الاصطناعي لم ينشئ مراكز البيانات من الصفر، بل أضاف طبقة جديدة من الطلب على بنية تحتية كانت موجودة أصلًا وتتطور منذ بدايات عصر الحوسبة.

لماذا أصبحت مراكز البيانات قضية كبيرة الآن؟

السبب الرئيسي هو أن حجم الحوسبة المطلوبة لخدمات الذكاء الاصطناعي أكبر بكثير من كثير من التطبيقات التقليدية، ومع توسع استخدام النماذج الذكية، أصبحت الشركات بحاجة إلى بناء منشآت أكبر واستهلاك كميات أكبر من الطاقة والتبريد والاتصالات، ولهذا أصبحت مراكز البيانات في السنوات الأخيرة جزءًا واضحًا من النقاشات المتعلقة بالطاقة والمياه والانبعاثات والضوضاء وتأثير البنية التحتية التكنولوجية على المجتمعات المحلية.
