CHOOSING the Right CLOUD
What to consider when using a cloud or managed service provider
orkloads are getting bigger. To manage all of this information and
application data, businesses have a few options: store workloads on
a company-owned server, tap the storage space of a managed service
provider (MSP) or go with a hybrid model that combines a private, on-premises
cloud with an MSP.

So, how does a business
decide? "There's no black or
white, nor an absolute right or
wrong answer," says Laura DiDio,
principal, Information Technology
Intelligence Consulting (ITIC), a
consultancy and research firm. As
an industry analyst, DiDio offers
insights on the considerations
and caveats organizations should
weigh when deciding how to manage their workloads.
Recent changes in IT and data
storage affect the ways nearly
all businesses operate their
The problem of sufficient storage space, for example, is fairly
new, DiDio notes. In the early dotcom days, the internet seemed to
easily accommodate all of the bits
and bytes generated online. But
in the past 10 to 20 years-the big
data era-more workloads have
been offloaded or outsourced
into the cloud. "I don't know
of any shrinking applications,"
DiDio says. And as workloads
increase, many organizations are
running out of physical space for
Some small and midsized
businesses (SMBs) also have
limited resources to devote to IT.
Why build an on-premises private
cloud when an outside vendor can
provide the same types of services
at a lower cost?
To decide whether to keep all
workloads in-house or move some
of them to an outside MSP, determine what your enterprise needs,
both now and in the future.
Make an Assessment
"Every organization, regardless
of vertical market, must perform
a thorough analysis and review
of what its workloads look like,"
DiDio says. Assess your IT environment by measuring how many
servers it has and how much
bandwidth it's consuming. She
