Data center needs are always changing. Managers can align their data center capacity by either choosing to stay with their own onsite capacity or migrating all of their applications to a public, shared cloud. Some may choose to rent space in a multi-tenant data center (MTDC), moving away from their own facilities entirely. So how do managers decide when and how to evolve their data centers?
On-Site Data Centers
scenario, managers control their data center at their
own location. An on-site data center improves efficiencies for some business needs.
Of course, it also carries maintenance requirements. With no crystal ball as to
what will happen in the future, it is more difficult to scale this investment
up or down: guess wrong, and the cost of this alternative can be much higher
than other choices.
There are a
couple of different reasons why companies choose to own their own data centers.
For example, some companies have static requirements and perform a significant
amount of processing on an ongoing basis, and they have invested in the data
center capacity to do that. Over time, they might make changes to the data
center, but it ends up being more expensive to go into a leased facility or
into the cloud unless there’s a good reason to do it, such as changes in
operations or technology.

enterprise perspective, the trend definitely appears to be toward increasing
the use of cloud over time. Private
and public cloud environments differ in several ways. When a company chooses a
private cloud environment, the company has the benefit of absolute control.
Internal operating costs may be much less than the monthly charges from using a
public cloud depending on the way the data center services are used.
cloud is a rental environment that offers much of the same facilities we see in
private cloud. Public cloud moves companies completely out of the
infrastructure business, and it might offer better security than small or mid-sized
enterprises can manage on their own.

the ability to pay for infrastructure as a utility rather than running it in
your on-premise environment. Even complex enterprise resource planning environments
with millions of dollars tied up in customization might not justify building
and owning a private data center. In this case, it may make sense to move into
a hosted facility and buy space, power, cooling and connectivity from the MTDC. And, since
it is commonplace for major public cloud, service and content providers to also
have a presence in MTDCs, enterprises can connect directly to them. This can significantly reduce latency and improve
the user experience, and simplify their planning by having their public and
private clouds, and carrier connectivity, under a single roof.
In the end,
different companies have different needs, and they use different data center
models to meet them. There are several alternatives available today. You can
customize the investment strategy and migration path to implement a combination
of hardware/software approaches. So, what’s your choice? Tell us in the
