The purpose of a data center is to keep your data and applications available at all times, but it is not necessary for you to go and build a data center from scratch for doing so. There will be specific requirements which will make it necessary for you to have a data center built for you and there can be some needs which can be fulfilled by taking data hosting or server co-location services from a data center service provider.

 

Difference
Own
Data Center
Hosted Data Center
Security:
Common perception is that data held in your own data center is more
secure, well, this is not entirely wrong
Ensure that the service
provider has put all the necessary security checks and measures in place.
Also check if the data center is certified by a standards body
Manageability:
There is no escaping on this front, if you own a data center you have to
deal with its manageability chores
You don’t have to deal with
any data center manageability issues; however, application and data
manageability is still your responsibility
Speed:
If you need to access the data at very high speeds, such as
Gigabit/sec, then a local data center is inevitable
With improved bandwidth
conditions, dedicated bandwidth of a few megabits/sec to the data center
is common, but not beyond that
Availability:
Appropriate data and application protection mechanisms, including
disaster recovery center have to be put in place
Most data centers provide
stringent SLAs for application and data availability, even in case of a
major disaster
Cost:
This will include the upfront cost and operational expenditures, which
can go quite high in the longer term
With a service provider, you
only have to pay for the service, which again can be very high if you have
huge amount of data
