However, if you are concerned about the security and privacy of sales and financial data, you can confine that data to a private cloud infrastructure while project management, time management and expense reporting applications move to the public cloud. That way, the vital data is created and managed internally but becomes part of the hybrid cloud, not the private cloud. Doing so may free up a lot of servers in the private cloud for production use or for mission-critical applications.
Large companies for years have been using cloud-based email archival services to store old email messages in accordance with Sarbanes Oxley or Basel II regulations. Consumers have used cloud-based email services for several years as well. It's only a matter of time, then, that everyday enterprise email takes a step in the same direction, especially for organizations that use either internally managed Microsoft Exchange servers or the Office365 cloud offering.
9. Human resources
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.
