What is Cloud?
Cloud Computing is the on-demand delivery of standardized IT services on shared resources, enabling IT to be more reliable through greater elasticity and scale, end-users to accelerate access to their IT needs through self-service, and the business to be more efficient through usage-based and SLA-driven services.
What Is a Private Cloud?
Private cloud is the implementation of cloud services on resources that are dedicated to your organization, whether they exist on-premises or off-premises. With a private cloud, you get many of the benefits of public cloud computing—including self-service, scalability, and elasticity—with the additional control and customization available from dedicated resources.
There are two models for cloud services that can be delivered in a private cloud: Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). With IaaS, you can use infrastructure resources (compute, network, and storage) as a service, while PaaS provides a complete application platform as a service.
