Private Cloud Deployment Best Practice

• Think Big, Start Small (what is your objective? how to measure success?)

• Cloud is more for business, not simply technology. Beware of human issues

• Make sure all key stakeholders buy in (otherwise it may fail)

• Identify the functions & features required (service catalog, workflow, chargeback, lifecycle management)

• Pilot deploy to an environment which is fully controlled by IT

• Review, review, review
