Conduct an inventory of the number of mission-critical applications your organization uses compared to other apps and you may be surprised to find how many of the latter, which are only used once in a while, crowd out the production apps. Moving as many of these infrequently used apps to the public cloud frees up your private cloud resources for production use-and, since you only pay for the public cloud services that you use, this approach may reduce your overall costs. For this reason, recruitment management, relocation, benefits administration and other HR applications are natural candidates for the public cloud.
10. Cloud-Based Anti-Spam and Anti-Virus Services
Many organizations use cloud services that perform anti-spam filtering and provide anti-virus services. Even if these services are hosted by the organization internally, they can be comfortably placed in your organization's public cloud instances.
Ultimately, CEOs and CFOs would like CIOs and senior IT management to make more use of public cloud because it moves fixed costs (infrastructure) into the variable cost column (pay-as-you-go services). On the other hand, concerns about security and privacy, and a feeling of loss of control of internal data, prevent companies from moving too aggressively towards the public cloud.
Fortunately, a hard look at the nature of individual applications and what they are used for opens up a whole host of applications that skirt all of these issues. As a result, they can be moved comfortably to the public cloud, which opens up additional capacity within the private cloud for mission-critical applications and other systems that deal with sensitive data.
