Data centers are buildings that are used by companies to store their data, applications, and infrastructure components, such as servers, storage, and switches.
Demand for data centers is growing due to their heightened cybersecurity, storage capabilities, and continuous monitoring as well as managed and self-service options. The demand can also be attributed to the growth in cloud computing, the Internet of Things (IoT), and artificial intelligence (AI).
The data center market was estimated to be worth $206.2 billion in 2021 and is projected to grow to $404.9 billion by 2028, according to BlueWeave Consulting.

Yarra City Council
The Yarra City Council provides many different services for the City of Yarra in Australia, which caused a need for reducing costs and complexity in their IT infrastructure. A data center through Equinix seemed to be a good decision for the Yarra City Council.
“There are a lot of data centers out there that look great. But the crucial factor for us was establishing a solid, in-depth relationship. Equinix and its team demonstrated that from day one — really going the extra mile to address our needs and build a foundation that would last for the foreseeable future.
“We felt comfortable it was a genuine partnership on every level, not only on costs, but in terms of a long-term relationship,” says Rick Bottigileri, innovation manager, Yarra City Council.
With Equinix, moving legacy IT systems from in-house data centers has reduced complexity, improved reliability, and reduced costs with Yarra City Council saving, for instance, on their air conditioning costs.
The new hybrid cloud and data center strategy means that the council is agile and can roll out new services almost overnight rather than eight months.
Fender is an instrument manufacturer that needed help managing their IT services for financial planning and e-commerce systems. They wanted to decrease IT costs without affecting their relationships with customers.
Fender did not want a solution that could take away from their focus on product development, customer satisfaction, and revenue growth. Fender soon realized outsourcing to a provider that specializes in the design, build, and operation of data centers was the most beneficial option.
“We looked at a dozen data center providers on the East and West coasts, and none of them could match what Iron Mountain had. When we toured Iron Mountain, we were sold,” says Jason Bredimus, VP of IT infrastructure, Fender.
With Iron Mountain, Fender increased uptime to 100% and gained more freedom to focus on other IT business needs.
What to look for in a data center company
Many data center companies offer a range of essential IT infrastructure, improved cybersecurity, managed services, and on-site support.
However, comprehensive energy-efficiency practices built into data centers, artificial intelligence tools, and in-market and edge locations are not provided by every data center company. These are the types of features that some of the leading players are offering customers in the data center market.
