Conclusion: Driving value from Infrastructure as a Service (IaaS) requires more than just a technical evaluation. IT Organisations must get clear understanding of the features and benefits of the billing model and how these are aligned to, and can be used to drive, the business’ objectives (e.g. faster time to solution, rapid scale-up and down, infrastructure costs to usage and revenues).
Achieving this understanding will require IT organisations to elevate the evaluation of the IaaS billing model to the same level of consideration as other key non-functional requirements such as availability, recoverability, and security. Organisations that fail to do this may find themselves locked into costly, inflexible IaaS contracts that are not aligned to the business objective and which fail to deliver the full potential of the Cloud.
