Gartner: 5 trends that will transform the data center

4

“The demand for IT as a service, combined with the

need to reduce costs, has pushed data centres to the

brink of a second transformation”

–

Hybrid IT:

Perhaps the greatest effect of public cloud computing on IT

concerns operations. IT organizations realize that not only do they need to

compete with public cloud service providers (CSPs), but also act as

intermediaries between internal customers and all IT services (internal or

external).

–

Internal clouds:

When businesses grow accustomed to consuming IT as

a service, IT organizations will be compelled to build internal clouds.

Unfortunately, building an internal cloud is hard work and few blueprints

exist.

–

Hybrid clouds:

Hybrid clouds are connections between two clouds,

usually an internal private cloud and an external public cloud

–

User-centric computing:

To compete in a global market and retain key

employees, organizations often have to accommodate staff who live in

remote locations and use personal devices for work.

–

Data center efficiency:

Competing with the external cloud requires IT

organizations to strive for hyper-efficiency in their data centers. If critical

data and applications are to be housed in an internal private cloud, IT

organizations must deliver internal IT services in an efficient, cost-effective

manner.

“

The new data centre:

In 2012, the data centre will

continue its transformation from a traditional, virtualised,

consolidated and centralised IT infrastructure into a
