Based on the types of service model, we can classify cloud as

 infrastructure-as-a-service (IaaS),

 software-as-a-service (SaaS)

Private cloud

In a private cloud, the computing services are offered over a private

IT network for the dedicated use of a single organization.

Private clouds provide a higher level of security through company

virtual interface.

Platform as a service (PaaS)

Platform as a service or PaaS is a type of cloud computing that provides a

development and deployment environment in cloud that allows users to develop

and run applications without the complexity of building or maintaining the

infrastructure.

It provides users with resources to develop cloud-based applications. In this type of

service, a user purchases the resources from a vendor on a pay-as-you-go basis and

can access them over a secure connection.
