Once again, the boardroom is in a bitter battle over what edict its
members will now levy on their hapless IT organization. On one hand,
hybrid cloud
is all the rage. Adopting this option promises all the cost savings of
public cloud with the security and comfort of private cloud. This
environment would not only check the box for meeting the cloud computing
mandate, but also position the organization as innovative and
industry-leading. Why wouldn’t a forward-leaning management team go all
in with cloud?
On the other hand, hybrid IT appears to be the sensible choice for
leveraging traditional data center investments. Data center investment
business models always promise significant ROI within a fairly short
time frame; if not, they wouldn’t have been approved. Shutting down such
an expensive initiative early would be an untenable decision. Is this a
better option than the hybrid cloud?
Hybrid Cloud Versus Hybrid IT
The difference between hybrid cloud and
hybrid IT
is more than just semantics. The hybrid cloud model is embraced by
those entities and startups that don’t need to worry about past capital
investments. These newer companies have more flexibility in exploring
newer operational options.
Mature businesses, on the other hand, need to manage the transition
to cloud without throwing away their valuable current infrastructure.
They also deal more with organizational change management issues and
possible employee skill set challenges. The new, bimodal IT model is
also a concern for these enterprises,
Forbes reported.
This is a tricky dilemma because both hybrid cloud and hybrid IT have
been known to deliver some pretty significant advantages. Some of the
biggest benefits of moving to an updated cloud or IT environment
include:
- Architectural flexibility that allows you to place business workloads where they make the most sense.
- Retention of technical control by keeping the final decision on if, when and where a multitenant IT environment is acceptable.
- Staff have the choice on the use of dedicated servers and network devices that can isolate or restrict access.
- Tighter management control, which often translates into a better ability to satisfy auditors and meet compliance requirements.
- Enhanced financial management because the company owns and funds the
base configuration with a capex budget while simultaneously gaining the
option to consume pay-as-you-go resources with opex funds for
unanticipated spikes.
- More technical stability through the use of dedicated servers for
baseline performance and supplemental multitenant cloud servers when
needed.
- Enhanced operating system flexibility for testing and evaluation or
providing technical customers the option to choose their preferred
environment.
- Promotion and support of innovation with an ability to spin up and tear down cloud servers quickly and easily for proof of concepts, pilots or software trials.
These hybrid advantages do need to be balanced with the operational
challenges of moving to such a nontraditional environment. Things like
automated resource provisioning/deprovisioning, cloud ecosystem
management, dynamic service pricing and other IT service brokerage
skills are new requirements for most organizations. This type of
technology shift may also require many personal and organizational
changes as well.
How to Manage the Shift
Shifting to a hybrid anything comes down to evaluating and managing
both traditional and cloud IT, balancing various on-premises and
off-premises suppliers and making dynamic choices about technology on
the fly as the business requires new capabilities. All these tasks must
be done simultaneously to achieve:
- User and customer empowerment;
- Application delivery optimization; and
- Service-centric IT that accelerates business responsiveness.
So in the end, the hybrid hype is really about
delivering business value.
Within these models, technology becomes an ecosystem of providers,
resources and tools. Interactions between old and new IT need to be
devised, modeled, tested, implemented and improved.
Functionally, IT organizations need to manage the end-to-end IT
service delivery model. They must be empowered to broker a set of IT
services, some of which are on-premises and some of which are
off-premises. The task of the IT organization is to offer internal and
external customers the price, capacity and speed of provisioning of the
external cloud while reducing IT service costs maintaining the security
and governance the company requires.
