What is a Data center in web
hosting?
A service that is used to provide a huge amount of electrical equipment
that can be either computers or other communication equipment is known
as a data center. It is an association that is solely maintained for the
purpose of managing or organizing data that is essentially required to
be used for daily operations. For example, the data center of a bank
would store all detailed information of its customers. All companies
have a data center of their own large scale companies may even multiple
data centers. For the large cities, the data centers are provided with
their own individual data location to prevent theft of data and to
maintain security of the important data contained.
The organizations providing the data center service handle the data
contained by them with utmost security as it is the lifeline of the
company. Therefore the data center organization maintains high level or
integrity and provides optimum functionality of the computer environment
that it hosts for. This is usually shown by the general layout of the
data center.
The data center can cover the area of a room to an entire building
depending upon its size. Most of the data are stored in for of racks
with corridors provided between them for easy access. The servers that
are available vary from 1u servers to huge silos that occupy various
tiles stacked upon the floor. Some of the mainframe computers and
storage devices are often as big as the racks and are placed next to
them.
The communications are mostly based on the ip protocol service in most
data centers. They are equipped with routers and switches which comprise
of the critical components that act as transporters of traffic to the
outside world from the servers. Using two or more upstream service
providers provide redundancy to the available internet connection.
Some of the datacenters run the basic internet and intranet services
like email servers, proxy servers, DNS servers etc.
As mentioned earlier, the data that is available in the centers are
treated with utmost security. Many network security elements are
employed to keep the data safe. Such as firewalls, VpN gateway,
Intrusion detection systems to detect malicious activities etc. are
incorporated. Common monitoring systems and other such applications are
also available. For added security for emergency situations such as
failure of communication inside the data center, offsite monitoring
systems are also provided.
