A data center is a facility composed of networked computers and storage that businesses or other organizations use to organize, process, store and disseminate large amounts of data..
Data centers have tier classifications which are established based on the topology of the site which drives the performance of the actual website. This classification is solely based on the combination of the type of designing topology and location of site. Such, tiered data centers have their own characteristics and advantages. However, in addition to the advantages with each tier class, operational sustainability of the data center is critical to ensure availability and reliability.
A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.
To put it in simpler words, a data center implies a central repository for servers, storage, management and distribution of valuable information. Data center is a physical structure of a building, a facility to provide computing capabilities, storage and networking.
The idea originally began of data center being a private server room in a company connecting user computers to the server and running applications on the server for granting access to users. In earlier days the organization was responsible for maintenance of servers, storage, and networking components and this required many IT personnel to manage the facility.
The services that are being offered by data centers are known as data storage, expendable data communications, and other security devices. Data centers provide the physical or virtual infrastructure services for companies to with hold computers, servers and other networking systems and components for the company’s IT requirements.
The data, and the business, keeps growing monotonously, in house data centers face the issue of constant hardware and infrastructure upgrades and updates. To overcome this issue third party data center service providers offer IT resources for clients for use in their business operations. Many business enterprise organizations are hiring services from third party data centers, such as cloud computing.
Therefore, we can understand that a data center requires huge storage or server areas and lands, storage arrays and networks and redundant telecommunications network and components to cater to the various needs of different types of organizations. Data centers are obliged to ensure reliability in services without any disruptions from the perspective of the user.
