Public and Private Cloud Computing
A public cloud is one in which the services and infrastructure are provided off-site over the Internet. These clouds offer the greatest level of efficiency in shared resources; however, they are also more vulnerable than private clouds. A public cloud is the obvious choice when
- Your standardized workload for applications is used by lots of people, such as e-mail.
- You need to test and develop application code.
- You have SaaS (Software as a Service) applications from a vendor who has a well-implemented security strategy.
- You need incremental capacity (the ability to add computer capacity for peak times).
- You’re doing collaboration projects.
- You’re doing an ad-hoc software development project using a Platform as a Service (PaaS) offering cloud.
