Data Centers and Daily Life
It happens quietly, without much thought. A resident checks the weather over morning coffee. A student streams a video for homework. A rancher pulls up a market report on a smartphone. A pilot files a flight plan. Throughout the day, thousands of these small digital interactions take place across Milam County. What many don’t see, however, is the vast network behind it all. The data centers, often located far away, working around the clock to store, process, and deliver information. While currently, largely invisible, this infrastructure is becoming just as essential as roads, water, and electricity. And even in a Milam County with a population of roughly 28,000 residents, the numbers are significant. As usage continues to grow, so will the demand for more data centers.
Experts estimate the average person uses 4 to 5 gigabytes of data per day, whether actively scrolling or simply carrying a phone that continues to sync in the background. That usage includes streaming video and music, social media and web browsing, email and cloud-based work, navigation, and automatic updates. Taken together, Milam County uses approximately 125 terabytes of data each day, totaling more than 45 petabytes annually. To put that in perspective, a single petabyte can store millions of high-quality photos or thousands of hours of high-definition video. The county’s growing digital footprint reflects just how connected even rural communities have become.
If the terabyte/petabytes thing confuses you, then you’re not alone – so, let’s simplify this. One of the clearest examples of this hidden infrastructure is found in everyday purchases. In a county of 28,000 residents, with each person making just one or two purchases per day, that results in 28,000 to 56,000 transactions daily. Each of those transactions triggers multiple data center interactions. With an average of 15 to 30 “touches” per purchase, that equates to roughly 420,000 to 1.6 million data center interactions per day, from purchases alone.
Let’s examine this a little closer.
Purchases made through Google Pay or Apple Pay are essentially digital versions of card transactions, but with added layers of security. Instead of sending actual card numbers, these systems use tokenized data, which is routed through payment processors, card networks, and issuing banks for approval. Along the way, multiple systems handle encryption, fraud detection, and authentication, often resulting in dozens of data center interactions in just a matter of seconds.
Traditional debit and credit card transactions follow a similar path, though without the same tokenization process. When a card is swiped, inserted, or tapped, the payment request travels from the point-of-sale system to a payment gateway, through the card network, and on to the customer’s bank. The bank verifies funds and sends approval back through the system. Even this familiar process typically involves 10 to 20 data center interactions, all happening almost instantly.
Even cash purchases, while simpler, are no longer entirely disconnected from the digital world. While the payment itself does not move through banks or card networks, the transaction is still recorded in modern point-of-sale systems. These systems update inventory, track sales, and feed accounting platforms, many of which are cloud-based. As a result, even a cash transaction typically generates 2 to 8 data center interactions, showing that even the most traditional form of payment still relies on digital infrastructure.
As demand for digital services grows, so does the need for the physical infrastructure to support it; and increasingly, that infrastructure is being built in rural counties. For local communities, this trend brings both opportunity and responsibility. Data centers can drive investment, expand the tax base, and improve infrastructure; however, they also require careful planning around power demand, water use for cooling, and long-term land use, particularly when working to avoid impacts on agricultural properties. As more of everyday life becomes tied to digital systems, counties will need to balance economic development with the preservation of their character and resources.
In Milam County, we have been approached by six data center developers. We chose to work with the two projects that had the financial capacity to move forward regardless of county participation. By engaging with them, we were able to ensure the projects are developed in a way that benefits our county, our schools, and our local businesses; rather than standing aside and allowing them to proceed without coordination or input. This approach also provides the county with a level of regulatory oversight we would not otherwise have. Conversely, we have declined to support several other proposals that required county incentives to be viable, effectively preventing those projects from moving forward in Milam County.
In the end, what feels like a simple daily routine; whether checking a phone, streaming a video, utilizing GPS, posting a podcast, or making a purchase; is supported by a vast and growing digital backbone. For Milam County, that means hundreds of terabytes of data and well over a million system interactions moving quietly each day. As technology continues to advance, the infrastructure of data centers will only become more critical and more visible, reinforcing the need to understand, plan for, and manage the systems that increasingly power everyday life.
