Data centre is the gathering of information technology operations of enterprises in one centre. The data centre enables the collection, archiving, storage, and distribution of large amounts of data. Data centres, which have existed in various ways since the invention of computers, offer various solutions to businesses with their advanced infrastructure. These centres usually have hardware such as computer and network technologies. The technical specifications of mechanical, electrical and security systems may vary depending on the importance level of the data stored or processed in the data centre. Router, power supply, communication connections, switch, storage system, server, security device used to minimize the risk of danger from the external environment and controllers that provide the distribution of the application are the elements in the data centre. These are solutions to meet all the requirements of a business for its IT department. These centres, which provide uninterrupted service 24 hours a day, 7 days a week, have thousands of servers with strong infrastructure support. In this way, businesses can protect the security of their data.

Special cabinets, computers, network technologies and special air-conditioning methods designed for the efficient operation of the system are special areas within the white areas called the heart of data centres. The most important function of these areas for institutions is to ensure that the servers in their centres can operate smoothly and regularly at all times. While some data centres offer non-shared data centre space specially prepared for businesses, others are only used for hosting services. Shared data centres are organized for a single service only and do not contain any other servers.

Any business in any industry that exists today produces and uses a wide variety of data over time. Businesses need a data centre for the privacy, security, storage, and operation of this data on the server. Government institutions, educational institutions, hospitals, banks, telecommunications companies, retail stores and financial institutions are examples of areas where the most precautions are taken in terms of data security. Situations such as loss of data, slow data transmission process or lack of access to data are critical for businesses. Data centres, which are important for many sectors and businesses at all levels, not only provide the protection they provide, but also increase the trust and loyalty of customers and ensure the profit of the business. In this way, businesses can secure both their own and their customers' data by protecting their data with the data centre. This situation contributes to the increase of user satisfaction and financial gain.

Organizing, storing, and backing up the data of an institution at certain intervals is important for the security of the institution. Data centres designed for applications in the information technology department of institutions meet many needs of an institution. It ensures the regular execution of activities in many areas such as e-mail and file sharing, management of customer relations, planning of corporate resources, management of database, installation of firewall and configuration management, provision of corporate communication and cooperation. Thus, it allows the creation of storage space for data transfers made inside and outside the institution. Data centres that offer the best performance in terms of network hardware and components save data even if there is an interruption on the network, preventing it from being lost. Thanks to the data centre areas that are directed in a controlled way, the data of any application created on the network is automatically synchronized and saved over the system. In this way, institutions can safely protect their data without worrying about insufficient storage space and deletion of data.
