Hybrid cloud
Hybrid will be the most common usage of the cloud — but this
requires the public cloud to be part of the overall strategy.
The defensive stance that dominated the large software vendor
strategies toward the cloud has been replaced in recent years
with a cloud-first approach. Today, most vendor technology
innovation is cloud-centric, with the stated intent of retrofitting the
technology to on-premises.
Failure to put the people and processes in place to consistently
leverage the security

If executive leadership can’t all reach agreement on the
question of “why?” — then any detailed plans of “how?”
or “what?” automatically start off at a disadvantage.

“Using cloud computing”
is not
— in and of itself —
a strategy.
Define and document long-term organizational
objectives
Before undertaking a broad data center
transformation project, IT organizations should
spend time to determine (and document):
 Why are they pursuing such a strategy (see
“Designing a Cloud Strategy Document”)?
 What business results are expected?
 What would “success” look like?
 What objective measures will determine how
to track progress against success metrics
over time?

Cloud exit strategy
Most organizations are adopting various public-cloud-
based services. However, few are considering a cloud
exit strategy as part of their overall cloud design plan.
Designing a public cloud exit strategy for infrastructure
as a service (IaaS) is relatively attainable. However,
devising an exit strategy for platform as a service
(PaaS) and SaaS is a lot more complicated and
sometimes not viable.
Public cloud services have failed in the past and will
inevitably fail at some point in the future.
However, the decision to exit a cloud provider should
not be taken lightly. It is expensive, operationally and
technically challenging, and time sensitive.
A public cloud exit strategy does not avoid lock-in.
Rather, it highlights risk mitigation considerations that
are often ignored.
