What’s Next?
Cloud provides the perfect opportunity to change the way your organization runs IT.
With cloud, IT has a much more positive influence on the business and is better aligned
with strategic goals. IT will no longer be a drain on company resources, and many enter-
prises will find that the newfound efficiency and agility of cloud adds huge value to their
bottom line. After all, IT is there to serve the business, not the other way around.
While few will dispute the hard cost savings of cloud, there is always a need to create a
compelling business case that clearly defines the value of agility and other soft benefits.
While it is important to remember that there are rare scenarios where cloud does not
make economic sense, generally, you’ll find a strong ROI and reduced TCO. Ultimately,
you won’t know the full costs and benefits until you define your business case and run
the models.
