What are Data Centers and Why Do We Need Them?

Two years ago, we were sitting in a sales meeting when my associate turned to me and asked, “Hey, have you tried this new AI thing called ChatGPT?” About half of the room had never tried it, so we pulled the site up and asked Chat about the solution to become wealthy.

Sadly, it provided the wrong answer. While the answer it gave included valid points such as working hard and being disciplined, of course we all knew what the right answer was: buying lots of real estate!

But, that was the spark for AI coming into our world in a much more tangible, accessible way than ever before. Many people believe that AI will shape the future.

Behind all of the incredible processing power of AI and the fascinating things it can do, there is the hard infrastructure necessary to make it happen – known as data centers. These are large warehouses that host the physical processors of all that computing. Data centers were a growing market prior to AI, but demand has now exploded and the need for more is still growing.

What are Data Centers?

Data centers are facilities that house the servers and network equipment that stores, processes, and distributes vast amounts of data for everything from streaming services and social media to cloud computing and financial transactions.

The Cost of Building Data Centers

Constructing a data center is a capital-intensive endeavor. The cost of building one varies widely based on several factors including location, size, design, and technological specifications. On average, the cost to build a data center can range from $500 to $2,000 per square foot. For a mid-sized facility, this can translate to total construction costs ranging from $10 million to $40 million or more.

Key cost components include:

• Land Acquisition and Site Preparation: The price of land varies significantly across different regions. The location for a data center must have access to high speed fiber and substantial power in order to handle the processing.
• Building Construction: This includes the cost of materials and labor for constructing the physical structure of the data center. Specialized requirements, such as reinforced flooring to support the heavy equipment and advanced cooling systems, add to the expenses.
• Infrastructure and Equipment: This is often the most significant portion of the budget, covering servers, storage devices, networking equipment, power distribution units, uninterruptible power supplies (UPS), and cooling systems.
• Security Systems: Data centers require advanced security measures, including biometric access controls, surveillance cameras, and fire suppression systems.
• Energy Efficiency and Redundancy: To ensure continuous operations, data centers invest in redundant systems for power and cooling, including generators, as well as energy-efficient technologies to minimize operational costs.

Sources of Electricity for Data Centers

Data centers are notorious for their substantial energy consumption. The electricity needed to power these facilities is a critical consideration in their development and operation. In the United States, data centers source their electricity from a variety of means:

• Grid Electricity: The majority of data centers are connected to the local electrical grid, drawing power from traditional sources such as coal, natural gas, and nuclear energy. The reliability of the grid and the cost of electricity are major factors in site selection.
• Renewable Energy: There is a growing trend among data center operators to utilize renewable energy sources such as solar, wind, and hydropower. Companies like Google, Amazon, and Microsoft have made significant investments in renewable energy to power their data centers, aligning with sustainability goals and reducing carbon footprints.
• Energy Purchasing Agreements: To ensure a steady supply of renewable energy, many data centers enter into power purchase agreements (PPAs) with renewable energy providers. These agreements secure long-term access to renewable energy at predictable prices.

Factors Driving Data Center Expansion

Several factors are propelling the rapid expansion of data centers in the United States:

1. Demand for Cloud Services: The proliferation of cloud computing services, offered by giants like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, is a primary driver of data center growth. As businesses and consumers increasingly rely on cloud-based applications, the need for data center capacity continues to rise.
2. Big Data and Artificial Intelligence: The rise of big data analytics and AI technologies requires significant computing power and storage, necessitating the development of more (and larger) data centers.
3. Internet of Things (IoT): The explosion of IoT devices, which generate vast amounts of data, further contributes to the need for expansive and sophisticated data centers which can securely process and store the information. For more on what the IoT is, check out our blog post on the topic.
4. Edge Computing: The trend towards edge computing, which involved processing data closer to where it is generated in order to reduce latency, is leading to the construction of smaller, widely distributed data centers across various locations.

Conclusion

Data center development in the United States is a dynamic and rapidly evolving sector, driven by technological advancements and increasing demand for digital services. As the digital economy continues to grow, data centers will remain crucial to supporting the infrastructure needs of businesses and consumers alike, ensuring the seamless flow of information in an increasingly connected world.
