While data centers have been the hottest topic in Texas over the past year, they’ve been around for much longer. Decades, in fact. The earliest “data centers” were those legendary giant room-sized computer mainframes, often built on military installations. As technology advanced and computers got smaller, data facilities started expanding outside of government property in the early 1980s, and the term “data center” became more common. A boom in personal computer use and the internet in the 1990s and the dot-com bubble around the turn of the century lead to the growth of network hubs, including the so-called “Data Center Alley” in Virginia. The industry’s shift to cloud computing and artificial intelligence has driven the most recent data center boom and the rapid expansion in Texas.
While the term “data center” can mean many different types of facilities, proposed developments most frequently will refer to one of four types of building.
Edge: Edge data centers are typically smaller, using between 1 – 10 megawatts of power. They are typically built near end users to increase internet speeds and support real-time applications. By design, they are widely distributed and built near urban or industrial areas to serve immediate needs. A subset of this type of facility is a micro data center, which are even smaller and designed to further reduce data processing latency.
Enterprise: Enterprise data centers are facilities built by one organization for their own internal IT needs, and do not host data for other entities. Enterprise centers were more common in the late 2010s and early teens, but have since drastically fallen in market share. Enterprise facilities tend to be less energy and cost efficient, so most companies are now seeking other types of facilities.
Colocation: Colocation facilities are the commercial leasing opportunities of the data center world, wherein multiple tenants will share space (and power, cooling, etc.) in one building. Colocation facilities allow organizations to reduce overhead costs and are the second most common type of data center facility currently being constructed.
Hyperscale: Hyperscale data center are the headline-makers. These are the biggest facilities, often using over 100 megawatts of power, designed to support massive computing needs like AI, cloud storage, and large-scale data processing. Amazon Web Services, Microsoft, and Google own/operate nearly 60 percent of hyperscale facilities as of late 2025.
A note on modularity and flexibility – data centers that are built in a way that can be reconfigured or modified can help extend the life of a data center facility. This could include modular structures like shipping containers, or even truly mobile facilities that can be moved to areas of need. This flexibility is also useful in disaster recovery.
