Private PaaS

Private PaaS derives its business benefits from making databases that might
contain customer or product data, transactions, or statistics available for
reuse. By allowing access to a library of functionality on these databases,
large organizations can divide responsibility and deploy applications
quickly, thus improving time to market. The IT department has the

responsibility of ensuring this data is always available.

(private cloud). In some situations, it makes sense to transport data through
physical means (such as hard disks and CDs). This is also a cloud carrier
function.
The cloud provider is the person, organization, or entity responsible for

making a service available to interested parties: the consumers. This
involves owning or contracting all hardware and software assets necessary
for delivering the service.
Providers depend on a number of components for their service. The most
important ones are as follows:
