Data centers are the backbone of the modern digital world, housing the crucial infrastructure that powers everything from social media platforms to cloud computing services. As the demand for data-driven technologies skyrockets, property owners have a unique opportunity to capitalize on this trend. This resource will delve into how data centers operate, their design, the roles of servers and storage, and the vital aspects of security and energy efficiency, all while highlighting how property owners can benefit from this growing market.


What is a Data Center?

Data centers are specialized facilities used to store and manage large volumes of data and applications for businesses and organizations. They consist of a network of computer servers, storage systems, and networking equipment, all designed to provide reliable access to information while ensuring optimal performance. A data center's primary function is to support data processing, storage, and distribution, enabling the hosting of websites, applications, and services. With the rise of cloud computing and big data, there has been a data center boom and data centers have become increasingly sophisticated, integrating advanced technologies to enhance scalability, security, and energy efficiency.


How do Data Centers Work?

Data centers host physical or virtual servers interconnected through networking and communication equipment, enabling the storage, transfer, and access of digital information. Each server, akin to a personal computer but with greater power, features a processor, storage capacity, and memory. To optimize performance, data centers utilize software to cluster servers and distribute workloads effectively.


Operations within data centers involve establishing and managing network resources, ensuring security, and monitoring power and cooling systems. The variety of data centers—differing in size, reliability, and redundancy—reflects the IT requirements of the enterprises that utilize them. The rise of cloud computing is driving the modernization of data centers, emphasizing automation and virtualization to enhance efficiency and adaptability.


Why are Data Centers Important?

Data centers play a crucial role in storing and managing the vast amounts of data that organizations depend on for their daily operations. The electronic exchange of information has become essential for almost every business and personal interaction. Even conventional activities like making a phone call, reading a book, or watching television have largely transitioned to digital formats. This increasing demand for new digital content necessitates extensive computing and networking infrastructure, all housed within data centers.


Without a data center, an organization has nowhere to house its hardware-based technology and, effectively, run its business. Specifically, data centers host the necessary hardware for businesses to run and support their IT environments, such as: 


  • Networks: This integrates physical and virtual servers, data center services, storage solutions, and external connectivity to deliver seamless access for end-users.

  • Application Delivery: To maintain application performance, data center mechanisms provide application resiliency and availability via automatic failover and load balancing.

  • Security: These include firewall and intrusion protection to safeguard the data center.

  • Computing Resources: These servers provide the processing, memory, local storage, and network connectivity that drive applications.


What are the Types of Data Centers?

There are various types of data centers that businesses can build or store their data within. These include: Colocation facilities, Enterprise, and Hyperscale. 


1) Colocation Data Centers

In colocation (or "colo") data centers, companies rent space within facilities owned by third parties, situated away from their own premises. The colocation provider manages essential infrastructure, including the building, cooling systems, bandwidth, and security. Meanwhile, the company is responsible for supplying and managing its own components, such as servers, storage, and firewalls.


2) Enterprise Data Centers

Enterprise data centers are constructed, owned, and operated by companies, specifically designed to meet the needs of their end users. Typically, these facilities are located on the corporate campus.


3) Hyperscale Data Centers

A hyperscale data center is a massive data center that provides extreme scalability capabilities and is engineered for large-scale workloads with an optimized network infrastructure, streamlined network connectivity and minimized latency. Hyperscale data centers are used by companies with vast data processing and storage needs, such as Amazon and Google.


4) Cloud Data Centers

Cloud data centers are an off-premises model of data centers where data and applications are hosted by a cloud services provider, such as Amazon Web Services (AWS), Microsoft Azure, IBM Cloud, or other public cloud providers.


5) Managed Services Data Centers

Managed services data centers are overseen by a third party, often referred to as a managed services provider, on behalf of a company. Rather than purchasing the equipment and infrastructure, the company opts to lease them.


The Future of Data Centers

The role of data centers has undergone significant transformation. With the rise of remote work and increased mobility, organizations are now accessing and utilizing data in new ways, presenting challenges for traditional data centers. As remote and hybrid work models become the norm, the demand for secure and reliable data access has surged. Consequently, organizations must ensure that their data centers consistently provide secure remote access for employees. This requires a robust and adaptable infrastructure capable of addressing the challenges of remote work, including bandwidth limitations, connectivity issues, and cybersecurity threats.


Rapid technological advancements, including AI, Internet of Things devices, and 5G, are driving modern data centers to consume unprecedented amounts of energy. McKinsey forecasts that data center demand will soar to 35 gigawatts by 2030, a significant increase from 17 gigawatts in 2022. Unfortunately, today’s energy grid is ill-equipped to meet the future needs of these data centers, particularly in rural areas and many international locations. Consequently, we can expect to see a concerted effort toward grid modernization in 2025 to address this growing demand.


This modernization will necessitate the construction of additional transmission lines, new substations, and improved coordination of diverse energy sources. For instance, combining renewable energy sources like solar with reliable fossil fuels can enhance energy efficiency and dependability around the clock. In fact, many data center developers are partnering with renewable energy companies to capitalize on the need for large amounts of energy for data center operations.


Suitable Properties for Data Centers

Location is crucial for data centers because it impacts operational efficiency, cost, and even the lifespan of the facility. A well-chosen site can lead to better energy consumption, lower latency, and increased security. However, there are only a finite number of properties that qualify for data center development, which drives up the price for data center developers to purchase or lease suitable properties.


This high level of competition presents a great opportunity for property owners to make money on their land by selling or leasing their property for data centers. In fact, the value of data center real estate has surpasses all other sources of taxable commercial property in the country combined, according to the Office of the Commissioner o If you're curious if your property could be suitable for a data center, check out LandGate's free property report, which will score your property's suitability for a data center on a scale of 0-100:
