Another major business benefit of Cloud is just-in-time Infrastructure:
In the past, if your systems or your infrastructure did not scale to your business requirement, then you became a victim of your own success. Conversely, if you invested heavily on your systems but the business does not progress well, you became a victim of your failure.
Cloud helps you in deploying applications with dynamic capacity management. With Cloud, software architects do not have to worry about pre-procuring capacity for large scale systems. The solutions are low risk because you scale only as you grow. Cloud Architectures can relinquish infrastructure as quickly as you got them in the first place (with in minutes).
