Private vs Public Cloud

Private vs Public Clouds



Public
A public cloud is one in which a service provider serves customers, with functionality like applications, infrastructure, and storage. These services are available to businesses and individuals over the Internet. Public cloud services may be free or offered on a pay-per-usage model; sometimes it’s referred to with the -aaS acronym, meaning “as a Service” as in IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service).

Private
The private cloud describes an internal computing model and architecture which provides hosted services similar to those of the public cloud, but reserved for corporate users and those that are approved; essentially, a private cloud is not open to the public and us usually setup behind a firewall. In a sense, this turns the IT department into the service provider or vendor for cloud resources. For those interested in reaping the benefits of virtualized cloud architecture, yet needing more control and security, this is a popular option.
Virtualization and data center automation allows for the scalability, maximizing hardware usage, and flexibility to support internal corporate clients. And, if your organization is so inclined, metering also allows you to charge departments based on their usage.
