Issues and Concerns
When considering adoption of a
cloud architecture, it’s important
to understand what the technology
can offer you and the main issues
you’ll have to deal with in each of
these new infrastructures. Only by
clearly understanding each of the approaches’
business and technical opportunities
and limitations will you
be able to select the best option on
the basis of your needs.
Besides the economic advantages
from a cost perspective, the main
competitive advantages are the exibility
and speed the cloud architecture
can add to your IT environment.
In particular, this kind of architecture
can provide faster deployment
of and access to IT resources, and
ne-grain scalability.
A recent survey indicated the issues
that beginner and experienced
enterprise cloud users face.4 For
beginners, the main issues are security,
managing multiple clouds,
integration with current systems,
governance, and lack of expertise.
Experienced companies face issues
of compliance, cost, performance,
managing multiple clouds, and
security.
The differences are understandable.
Different problems arise on the
basis of the degree of advancement of
cloud architecture adoption. Early on,
the main issues are resource expertise
and control because the company
hasn’t acquired enough knowledge of
and experience with the architecture.
For more experienced companies,
performance and cost are important
because the architecture’s limitations
might have started emerging.
Both groups must deal with security,
compliance, and managing multiple
clouds. Regarding security and
compliance, some problems might
arise from the multitenant architecture.
Some of these problems might
not be solved, which might tip the
balance toward a private or hybrid
cloud. Such a decision is plausible, in
keeping with the issue of managing
multiple clouds.
