What Is a Data Center And Why Is It Important?

what is a data center and why is it important.

When the world's technology and social media giants switch to cloud technology, you will often hear the term "data center". From Google, Facebook, to Microsoft, probably every top technology company needs data center support. In the context of modern technology, it can be said that it is impossible for a technology company to function without them. So, what is a data center, and why is it so? important?

What is a Data Center?

A data center is basically a large computer that stores and processes information. Any company or organization that handles user data definitely needs a data center. In other words, if you have an account on any website, or if you have used the internet to search, Either way, you're bound to use up some space in data centers located in multiple locations around the world.

Data centers are usually referred to as a single entity but are actually made up of racks, cabinets, cables, batteries, and backup generators in the event of a power failure. Because they store up to billions of megawatts of information, they also have cooling systems to keep them from overheating.

So, think of a data center as a supercomputer that stores all the information online for you, and millions of people around the world.

How was Data Center History Discovered?

Even though data centers are buzzing right now, these physical facilities are not a new invention of the twenty-first century.

It is generally believed that the first facility that could be considered a “data center” was built in 1946 in the United States. It was called ENIAC (Electronic Numerical Integrator and Computer), and was used by the United States military to store defense codes and other critical information. The ENIAC was huge, covering 1,800 square feet, and weighing up to 30 tons.

In the 1960s and 70s when commercial computers began to gain popularity, large computers similar to the ENIAC began to appear on the market. The veteran IT company IBM was at the forefront of such infrastructure at the time. In 1964, IBM launched The world's first “supercomputer” called the CDC 6600. Come to think of it, this supercomputer has all the features of a data center.

But it wasn't until the 1990s that the term “data center” was coined. With the internet rapidly taking over the world, IT companies at the time saw the need to move their servers to dedicated computer rooms.

Where is the Data Center Located?

Data centers are ubiquitous around the world, but most, if not all of them, are located in areas free from natural disasters. Many are also near a stable and reliable power source, ensuring better internet connectivity. Â Proximity is also another important aspect: the closer the data center is to the business, the faster the overall business internet speed will be.

When starting to spread overseas, data center companies also consider a country's tax laws, water and electricity costs, and geopolitical risks as important factors.

As data centers become larger in storage capacity, many companies are also starting to consider security as one of their main concerns. Availability of on-site security, such as surveillance cameras and security personnel, and security software for each component is now mostly available 24/7.

There are more than 6,000 data centers in about 126 countries globally. Currently the largest data center in the world is located in the United States, covering an area of ​​7.2 million square feet called The Citadel. It is located in Tahoe Reno, Nevada, and houses data from some of the most important names in business, including eBay, Amazon, HP, Boeing, and Bloomberg.

Types of Data Centers

Data centers are divided into three main types. The first is an enterprise data center. These are facilities owned and operated by the technology company itself. For example, Google, Microsoft, and IBM have enterprise data centers in various locations around the world.

Next is data center colocation. This is when companies lease several racks of space from enterprise data centers. Big tech companies like Facebook also have colocation data centers in addition to their enterprise data centers.

With cloud technology becoming increasingly important in the tech world, cloud data centers are also becoming more popular. Technology companies that have businesses dedicated to cloud computing usually also operate cloud data centers. Amazon Web Services (AWS) and Microsoft Azure are examples.

Now that we know the different types of data centers, who are the world's major data center providers? Apart from the big tech names we all know, some you should know are NextDC, SpaceDC, Equinix, and Digital Realty. The first two are headquartered in Australia and Singapore, while the latter two were founded in the United States.

Why Are Data Centers Important?

Data centers are important because everyone uses data. From individual users like you and admins to multinational companies. Everyone may have used the services provided by the data center.

Whether it's emailing, shopping online, playing video games, or simply browsing social media, every byte of what you store online is stored in the data center.

For medium and large enterprises, cloud data centers are quickly becoming the preferred mode of data storage. This is because they are much more secure than storing information with regular hardware. Cloud data centers offer enhanced security protections such as firewalls, and backup components in case of a breach. security.


So what is a data center? A data center is a physical location that houses core IT and computing services and infrastructure. Simply put, a data center is a physical place to store and compute data. Data center is the lifeline that keeps our digital world going.
