Data centers are used by companies to organize, process and store the
large amounts of data.
There are many data center service providers. The top companies amoung them include Equinix, Digital Realty Trust, China Telecom, CenturyLink, Verizon, Amazon Web Services, DuPont Fabros Technology, Level 3 Communications, CyrusOne, Interxion, AT&T, NTT Communications, etc.
Following are the services provided by data center companies.
&#; Wholesale Colocation: In this type of service, customer can lease entire data
center or larger portion and will have high level of control over
the facility and equipments. The lease period will be in several years.

will be about a year or less than 1 year.
Following are the benefits or advantages of Data Center:
&#;It offers services to the customers based on affordable rates
in various plans as per lease period and requirements.
&#;It offers robust software and hardware ecosystem.
&#;It offers great system performance by distributing load across cluster nodes.
&#;The users or customers need not have to worry about
hiring people for maintenance in order to manage the data centers.
&#;The data centers offer instant scalability based on changes in
capacity requirements by customers.
&#;The services are available always and without any failover due to backup
of systems.
Following are the drawbacks or disadvantages of Data Center:
&#;Companies hiring the resources from the data center providers will not have
complete control locally. This is due to the fact that the human resources and hardware lies at the remote location.
&#;The usage and quality of data center services vary based on internet connectivity at the
customer premises.

Grouping of IT resources such as servers , databases ,networking and communication devices in close with each other rather than having them geographically dispersed. Advantages of data center :- 1. It allows for power sharing 2. Higher efficiency in usage shared IT resources 3. Improved accessibility for IT personnel(less management team is required) DIFFERNET TYPES OF INFRASTURUCTURE INSIDE DATA CENTER 1 .BUILDING INFRASTRUCTURE:- &#; BUILDING SYSTEM&#; electrical system, fire suppression, lightning ,security etc. 2 .DATA CENTER INFRASTRUCTURE :- power ,cooling racks ,management, physical security, fire suppression etc. 3.

The host operating system consumes CPU, memory and other hardware IT resources. Licenses are usually required for host OS, in addition to individual licenses for each of their guest OS.
RESOURCE POOLING
It is grouping of identical IT resources and maintained by system that kept synchronization of resources.
There could be four types of pools:-
1. Physical server pools:-It is composed of rack mounted servers with operating system.
2. Virtual server pools:-It is composed of virtual server with different OS and RAM.
3. Storage pools:-it is composed of different storage devices/containers.
4. Network pools:-It is composed of physical connectivity devices such as routers ,switches or firewall devices.
Workload distribution
It is the distribution/(scaling) of IT resources according to the workload. there could be two ways to scaling:-
1.Vertical scaling:-Replacement of existing IT resources with the resources which have higher capacity.
2.Horizontal scaling:-Addition of the same type of IT
