The million dollar question has been «Can an organization move all its applications to a public cloud?». Instead of moving all applications to the public cloud, many organizations are choosing a hybrid approach where on-premise resources can be leveraged and can interact with external resources. A hybrid cloud is a combination of public, private and community clouds. Most private clouds are internal, however there can be situations where private clouds are hosted at a vendor site. For this discussion, I am focusing on the private clouds that are hosted internal to the organization. Utilizing hybrid clouds may require redesigning systems based on a determination of what data resides internally and what data can be moved externally. Generally organizations choose to have critical and sensitive data reside internally and move non-sensitive data outside the organization. Core business applications or services can be retained internally and can interact with the non core applications or services that can reside external to the organization. One of the programs I led in the past used the public cloud to gather non sensitive information and subsequently this data was funneled internally. This information was then manipulated and rendered for applications that performed customer reporting and related business intelligence.
