The positive value proposition relates to the speed of innovation. If some process prototyping or technology prototyping needs to occur, and the possibility of doing so is constrained by environment/hardware availability, Cloud Computing can be of immense assistance. While procuring Virtual Machines, Messaging Frameworks and Storage is particularly convenient, it is possible to do the same for Platforms from the vendors of those platforms. Of if one is involved with something associated with significant intellectual property, there is an inherent risk. Even then if there may be circumstances where the sheer convenience in innovation can sway towards the acceptance of that risk. Where the Cloud value proposition requires much more closer examination is when the latter involves off-loading of Core Business-Operational streams. I should state here that these remarks DO NOT apply to Private Cloud environments, that may well offer the flexibility of the public or community cloud with the absence of the monitory impost. That said, if any organisation requires significant expansion of their On-premise Data-Centre footprint in order to accommodate a new or enhancing Business-Operation, the negative value proposition should be considered from the view points of Monetary, Security and Data-Sovereignty, if that applies.
