Therefore, if a one-time big data project requires 10,000 servers and the job needs to be done in a few days, or even a few hours, then the public cloud may be the right choice. It may not make sense for any organization to buy that many physical servers, even if they are virtual.
Company information, product pictures, price information, brochures and other write-occasionally, read-often websites and portals are obviously natural for the public cloud. A public cloud provider's level of security and privacy may be more than enough for information that is intended for the public.
6. Customer Relationship Management
CRM software such as Salesforce.com is already on the cloud, so customer and prospect management should work well on the public cloud. Usually they are also not that tightly integrated with other internal systems-save for email or, perhaps, sales and order management- which makes CRM systems easier to move to the public cloud than many other applications. (Whether customer master data should be so loosely coupled with other enterprise data is another matter entirely.)
7. Project Management, Expense Reporting and Time Management
As with CRM, these three mission-support (as opposed to mission-critical) applications are a good fit for the public cloud.
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.
