[ Cloud Computing ] Re: Cloud Computing ROI model

Geva,

All your points holds good.

However, for a knowledgeable customer, there are more selling points
or differentiators (in terms of your services) needed

* Reliability is seen as an issue on the cloud - How does one address
this?

* Protection/Security is seen as a major issue on the cloud :- How
does one address this?

* Cloud deployment for moderate to complex applications is not easy -
(Custom App-stack/Machine Images) - How does one address this?

* Monitoring ,Management and maintenance of deployed apps are not so
easy for every app- How is this addressed?

* There are various clouds / cost models , If one can make a
comparison, consult and be able to help a client to find the best
choice for their budget and service them
this would be add punch to the Value -Proposition?

In essence, it is granted that clouds come with their inherent
benefits and value , However to sell this model effectively with an
ROI model, from a solution provider or SaaS viewpoint, a number of
points (i have mentioned a few) have to be considered and factored in
the value proposition to a end user,dependening on one's capabilities.
