For more than 47 years, I have watched technology move from rooms full of mainframes to the pocket-sized devices we all carry. What has stayed constant, and become even more essential, is the quiet infrastructure that makes modern life work: reliable data centers. These facilities are not just the engine behind artificial intelligence. They are the foundation for thousands of applications that individuals, businesses, schools, and public agencies depend on every single day, including the voice and messaging platforms your customers use to reach you.
Local Business VoIP is the small-business site of Carolina Digital Phone, Inc., which I founded in Greensboro in 2000. We have hosted voice in data centers for more than 20 years, so this is a subject I think about every day, and one most business owners never have to think about at all. That is rather the point.
Quick answer: why do data centers matter to a business owner?
Because nearly every tool you and your customers use, from email and maps to banking and your business phone, runs in one. A data center provides the power, cooling, physical security, and connectivity that a server closet in an office cannot, and that is why organizations keep moving applications and communications out of their buildings. For voice specifically, a platform spread across several data centers keeps calls and messages flowing even when one site, or your own office, has a problem.
- Data center
- A purpose-built facility that houses servers and network equipment with redundant power, cooling, security, and high-speed connectivity.
- Colocation
- Renting secured space, power, and connectivity inside someone else's data center for your own equipment.
- Geo-redundancy
- Running the same service in several data centers in different places so a failure at one does not take the service down.
- Small modular reactor (SMR)
- A compact, factory-built nuclear plant being evaluated as dedicated, always-on power for large data centers.
Which everyday applications rely on data centers?
Think about the tools you reach for without a second thought. A long list of mobile and everyday applications relies on secure, always-available data center capacity:
- Email and calendar platforms such as Gmail, Outlook, and Apple Mail
- Messaging and collaboration tools including WhatsApp, iMessage, Signal, Slack, and Microsoft Teams
- Social and professional networks such as Facebook, Instagram, LinkedIn, TikTok, and X
- Navigation and mapping services like Google Maps, Apple Maps, and Waze
- Streaming platforms for video and music (Netflix, YouTube, Disney+, Spotify, Apple Music)
- Banking, payments, and financial apps (mobile banking, PayPal, Venmo, Square)
- Shopping and delivery services (Amazon, Walmart, Target, DoorDash, Uber Eats)
- Productivity and cloud office suites (Google Workspace, Microsoft 365, Dropbox, iCloud, Google Drive)
- Video conferencing and remote work tools (Zoom, Google Meet, Webex)
- Ride-sharing and transportation apps (Uber, Lyft)
- Health and wellness applications, including telemedicine portals and fitness trackers that sync data
- Weather, news, and local information apps
- Voice assistants such as Siri, Alexa, and Google Assistant
- Smart-home and IoT services that keep lights, thermostats, and security systems connected
- Online gaming platforms and multiplayer services
- Government, education, and public-safety portals, emergency notification systems, and school communication tools
Every one of these services lives in data centers. When you tap an app, send a message, place a call, or pull up a map, the request travels to a facility designed for power, cooling, security, and high-speed connectivity. The Uptime Institute and IDC have documented for years how cloud and colocation facilities underpin the majority of digital services consumers and businesses use daily. The same infrastructure hosts the hosted voice and messaging platforms that businesses, schools, and public-sector organizations rely on to stay in touch with customers, parents, employees, and citizens.
The server closet next to the water heater
A few years ago I visited a mid-sized accounting firm in the Triad that wanted to replace its phone system. The owner walked me to the back of the office and opened a closet door. Inside was the firm's phone switch, its file server, its backup drive, and the building's water heater, all sharing about 30 square feet with a mop bucket. The server had a consumer power strip. The backup drive was on a shelf above the water heater. The firm's entire client history, and every phone call that came in, depended on that closet staying dry, cool, and powered.
The owner was not careless. He had done what nearly every small business did for 30 years: bought equipment, found a spot for it, and hoped. What changed is that the hope is no longer necessary. We moved his voice to our hosted platform in a week. His IT provider moved the file server to a cloud service the following month. The closet now holds the mop bucket and the water heater, which is what it was built for. He told me later that the strangest part was realizing how much of his business had been sitting on that shelf, and how little he had thought about it until someone opened the door.
Why are organizations moving out of on-site server rooms?
Because the dependence on these services will only grow, and the office server room cannot keep up. More organizations no longer want to house servers in their own buildings. On-site equipment is harder to secure, more difficult to keep updated, and often requires substantial internet bandwidth just to serve employees who work remotely. Moving communications and applications into professionally managed data centers removes those burdens and improves reliability. Gartner and similar research firms have consistently shown the shift toward cloud-hosted communications and applications as organizations seek greater resilience and lower operational complexity.
Professional data centers address the security limitations of a typical office server room through layered physical and operational controls that go well beyond what most organizations can sustain in a back-office closet. The table below compares the two.
| Protection | Typical office server room | Professional data center |
|---|---|---|
| Physical access | A door, maybe a lock, often shared with storage | Multi-factor badge and biometric access, mantrap entries, escorted and logged visitors, perimeter fencing, 24/7 security staff, continuous video monitoring |
| Power | Wall outlet, a power strip, perhaps a small UPS | Redundant utility feeds, battery systems, and diesel generators with fuel contracts, tested on a schedule |
| Cooling and environment | Whatever the building HVAC provides | Redundant cooling, real-time temperature and humidity monitoring, advanced fire detection and suppression |
| Network | One internet connection, one firewall if any | Multiple carriers and fiber paths, firewalls, intrusion detection and prevention, network segmentation, encryption in transit and at rest |
| Oversight | Whoever remembers to check | Regular third-party audits against SOC 2, ISO 27001, or industry-specific standards |
| Who maintains it | Your staff or an outside IT contractor, when available | The facility operator and the service provider, around the clock |
These controls explain why businesses, schools, and public-sector agencies increasingly prefer purpose-built facilities over on-premises servers that are harder to secure, harder to update, and more exposed to physical and environmental risk. They also explain why a hosted phone system is more resilient than the premise PBX it replaces: the PBX has one building, one power supply, and one connection.
Where does Carolina Digital Phone host its voice platform?
In four locations, so that calls and messages remain available even when one site experiences an issue. We have hosted voice and communications services in data centers for more than 20 years, and the current design is the result of everything we learned along the way.
Downtown Greensboro, North Carolina
Our own facility with just under 2,000 square feet of data-center space, a 250 kW diesel generator, and multiple dedicated fiber connections to Tier 1 providers. Local customers are welcome to see it.
MCNC, Research Triangle Park
Colocation space at MCNC, the same environment where many North Carolina schools and government agencies host applications and obtain internet access.
Equinix, Dallas, Texas
An Equinix data center that provides geographic separation from the Carolinas, so a regional weather event or fiber cut does not affect both sides of the platform.
Amazon Web Services, Northern Virginia
Servers hosted in AWS facilities in the Ashburn area, one of the largest and most connected cloud regions in the world.
This geo-redundant design is what allows us to target 99.999 percent uptime and deliver calls in microseconds. If one location has a power event, fiber cut, or other disruption, the platform continues to route voice and messaging through the remaining sites. Customers do not have to manage generators, cooling, security, or software updates. Those responsibilities stay with the data-center operators and with us. I wrote about the carrier side of that design in geo-redundant VoIP service, and about what it means during a storm in telecom resilience. For a business weighing whether this is worth it, do cloud phones need internet answers the question I hear most.
How will data centers be powered in the future?
Looking at the broader energy picture, many large data centers are exploring dedicated power beyond the traditional grid that serves homes and businesses. Small modular reactors, sometimes described as micro-nuclear plants, are being evaluated as a cost-effective, reliable way to supply the continuous electricity and cooling that high-density computing requires. The U.S. Department of Energy describes them as factory-built units of up to about 300 megawatts each, designed to be added to a site in modules as demand grows.
In Virginia, Dominion Energy has entered a memorandum of understanding with Amazon to explore SMR development near the North Anna Power Station, with the goal of adding at least 300 MW of new capacity to support regional demand driven largely by data centers. Dominion's integrated resource plans also include multiple SMRs beginning in the mid-2030s as part of an all-of-the-above approach to meet rising load. These efforts are documented in public announcements from Dominion Energy and in coverage by Utility Dive, Virginia Business, and Data Center Dynamics. Commercial SMRs are still advancing through development and regulatory stages, but the interest from both utilities and large technology operators signals a practical path for dedicated, always-on power tailored to data-center needs. North Carolina is watching closely: the state's own utilities have filed plans that include advanced nuclear, and the Research Triangle is home to several of the companies designing these reactors.
Why do we accept new infrastructure, then forget it is there?
Because that is what good infrastructure does. As a technology society, we have become dependent on powerful computing in the same way earlier generations became dependent on electricity. In the early 1900s, when electric service reached more and more homes and businesses, people quickly realized that life without reliable power was no longer practical. Today it is hard to imagine a home or workplace without it. Data centers are following the same path, and so is the voice service that runs in them. I have lived through more of these transitions than most, so permit me a short tour.
Transportation. When the automobile arrived, many assumed the horse and buggy would remain the standard for moving people and goods from farms and factories to stores. Henry Ford's Model T and the moving assembly line proved otherwise. We are now fully dependent on motor vehicles, highways, and logistics networks.
Broadcasting. Early crystal radios and AM broadcasts brought news and music into living rooms. FM, car radios, and then television, from black-and-white sets to color, cable, and satellite, made the world feel smaller.
Food storage. Iceboxes gave way to electric refrigerators such as the early GE Monitor Top, then home freezers and combination units that transformed food storage and ended the daily trip to the market.
Aviation. Commercial flight moved from the first scheduled passenger routes of the 1910s and 1920s to the jet age and aircraft like the Boeing 707, turning multi-day train or ship journeys into a few hours.
Telephones. Candlestick phones and party lines evolved into rotary dials, touch-tone, cordless handsets, the first cellular phones such as the Motorola DynaTAC, and eventually smartphones that combine communication, photography, navigation, and computing. The copper lines that carried the first century of that story are being retired now.
Computing. Room-sized mainframes like ENIAC gave way to personal computers such as the Apple II and the IBM PC, then the internet, from ARPANET to the World Wide Web and graphical browsers, and finally the cloud services we use today. I was writing COBOL on mainframes when the first of those personal computers appeared, and I opened North Carolina's first Apple store in Charlotte because I could see which way it was going.
Health. Penicillin's mass production during World War II, followed by the polio vaccine and later modern imaging and pharmaceuticals, changed what a lifetime looks like.
Comfort and convenience. Window units and central air conditioning made large regions of the country livable and productive year-round. Paper maps and AAA TripTiks gave way to the first consumer GPS units and then to the mapping app in your pocket. Diners Club and BankAmericard, later Visa, evolved into magnetic-stripe cards, chip cards, contactless payments, and mobile wallets. Electric washing machines, microwave ovens, and dishwashers turned once-laborious chores into background tasks.
Each of these once-novel technologies is now woven so deeply into daily life that most of us notice them only when they are unavailable. We adapted to and accepted them because they improved daily life and economic activity. Data centers and the applications they host are the next chapter. Smart, well-run facilities, whether powered by the traditional grid, dedicated generation, or emerging options such as small modular reactors, will continue to make the connected services we rely on possible.
What does this mean for your business phone?
It means the question is no longer whether to run voice in a data center. Every national provider does, and so do we. The question is whose data centers, how many of them, who owns the accountability when something fails, and whether you can pick up the phone and talk to that person. For organizations that want reliable voice, messaging, and related services without the complexity of on-site servers, that infrastructure is already here. I would rather you got it from a company that built its own facility in the city where you do business, and that is the case I make in why Carolina Digital Phone, in doing business local in North Carolina, and in our history. It is the standard behind the way we work as a trusted communications partner, and you can see the plans it supports at carolinadigitalphone.com/pricing.
The future of everyday applications depends on the same principle that made electricity, transportation, aviation, computing, household appliances, and countless other innovations indispensable: reliable, professional infrastructure that simply works.

Frequently asked questions about data centers and hosted voice
What is a data center?
A data center is a purpose-built facility that houses the servers, storage, and network equipment behind digital services, with the power, cooling, physical security, and high-speed connectivity those systems need to run around the clock. When you send an email, open a map, or place a call through a cloud phone system, the request is handled in one or more data centers rather than on a computer in your building.
Which everyday apps depend on data centers?
Nearly all of them: email and calendars, messaging and collaboration tools, social networks, navigation, streaming, banking and payments, shopping and delivery, cloud office suites, video conferencing, ride sharing, telemedicine and fitness apps, weather and news, voice assistants, smart-home devices, online gaming, and the government, school, and public-safety portals that communities rely on. Business voice and messaging platforms run in the same facilities.
Why are businesses moving servers out of their offices and into data centers?
On-site equipment is harder to secure, harder to keep updated, more exposed to power and environmental problems, and often needs significant internet bandwidth just to serve remote employees. A professionally managed data center takes on generators, cooling, physical security, and software maintenance, which improves reliability and removes a burden most small organizations cannot sustain in a back-office closet.
How secure is a professional data center compared with an office server room?
Much more so. Typical controls include multi-factor badge and biometric access, mantrap entries that prevent tailgating, 24/7 on-site security, continuous video monitoring, perimeter fencing, escorted visitor logging, advanced fire suppression, temperature and humidity monitoring, redundant power and cooling, firewalls, intrusion detection, network segmentation, encryption in transit and at rest, and third-party audits against standards such as SOC 2 and ISO 27001.
Where does Carolina Digital Phone host its voice and messaging platform?
Across four locations: our own facility in downtown Greensboro, North Carolina; colocation space at MCNC in Research Triangle Park; an Equinix data center in Dallas, Texas; and Amazon Web Services in Northern Virginia. If one site has a power event, fiber cut, or other disruption, calls and messages continue to route through the remaining sites.
What does geo-redundant mean for a phone system?
It means the platform runs in several data centers in different places at the same time, so a problem at one location does not take the service down. Carolina Digital Phone's four-site design is what lets us target 99.999 percent uptime. Customers never have to manage the generators, cooling, security, or software updates that make that possible.
What is 99.999 percent uptime in practical terms?
About five minutes of unplanned downtime in a year. It is the standard carriers have used for voice service for decades, and it is the target a geo-redundant hosted platform is built to meet. No provider can promise that every desk phone in every building will work through every local outage; the target applies to the platform itself.
Does a cloud phone system still work if my office loses internet?
The platform keeps working because it does not live in your office. Incoming calls can be redirected to mobile apps, another location, or voicemail-to-email automatically. Desk phones in the affected building will not register until the connection returns, which is why a backup internet path or a mobile app on key staff phones is part of a good continuity plan.
What are small modular reactors, and what do they have to do with data centers?
Small modular reactors, or SMRs, are compact nuclear plants designed to be built in a factory and installed in units of tens to a few hundred megawatts. Large data center operators and utilities are evaluating them as a way to supply the continuous, carbon-free electricity that high-density computing requires. In Virginia, Dominion Energy and Amazon have agreed to explore SMR development near the North Anna Power Station. Commercial SMRs are still working through development and regulatory steps.
Is hosted voice as reliable as the old phone company?
When it is built on geo-redundant data centers with carrier-grade connectivity, yes, and in most respects more so. The copper network it replaces is being retired, and a single office PBX has one power supply, one building, and one internet connection. A hosted platform spread across several facilities has none of those single points of failure.
Why does it matter that a provider owns or controls its own data center space?
Because the provider, not a distant reseller, is accountable for the environment the service runs in. Carolina Digital Phone has hosted voice in data centers for more than 20 years, operates its own Greensboro facility with a 250 kW diesel generator and multiple dedicated fiber connections to Tier 1 providers, and chooses its colocation and cloud partners directly. That is the kind of thing a local customer can come and see.
