Why Is It Important For Businesses?
For any business, adapting to new technology is crucial for survival. Even though a business is able to manage tasks with traditional methods, to compete in the industry it will have to update. Data centres would ease the workload because they would be carrying it. Here is how your business will benefit with data centres:

You can easily share files across via your email. For Gmail users, everything is saved in the cloud and you can choose who gets access to your documents.
Not just documents, all your presentations, graphs, worksheets, videos, etc can be stored and accessed from anywhere.
A database helps an organisation in multiple ways- Customer Relationship Management, resource planning and more.
It powers the deployment and development of artificial intelligence and machine learning algorithms
Communication and collaboration are easy when all parties have access to the same data and it is easy to use.

Conclusion
There are many types of data centres depending on their purpose- Enterprise data centres, cloud data centres, managed services data centres and colocation data centres. Most enterprises have their own data centres for their operations, for example, Amazon uses its data centre for storing and accessing data on its private cloud for its warehousing, orders, delivery, management, and other services. The modern data centre is the centre around which the world is advancing.
