The basics of data centers
What is the data center?
A data center is a dedicated space inside a building, which is used to house IT, or telecommunication related devices like servers, storage, air-conditioning, and various security equipment.
Components of data center
Following are the main components of a data center:
- Servers and racks
- Network connectivity
- Security system
- Monitoring system
- Cooling system
- Policies and procedures
1. Servers and racks
Servers are one of the critical components of a data center and the racks house those servers. The servers are used to serve clients and host websites.
Power is needed to keep every equipment up and running in a data center, therefore, an interruptible power is ensured by using UPS and backup generators.
3. Network connectivity
Network connectivity ensures that all the equipment in a data center is connected with outside work like the Internet. Routers and switches serve this purpose.

Various security equipment is used to keep the data center safe from any intruders and from physical damage in case of earthquake and fire.
5. Monitoring system
It is important from the business point of view to keep equipment in the data center up and running 24*7. Various monitoring applications are installed to monitor the whole infrastructure. In case of any incident, those applications alert the concerned teams.
6. Cooling system
In order to suppress the heat generated by various equipment in a data center, a sophisticated air conditioning system is used.
7. Policies and procedures
Data centers are properly operated by a set of policies and procedures and everyone must adhere to those policies.
