We have discussed the three standard cloud service models. The service model defines the what. What is unique about each model? What are they trying to solve? What are their strengths and weaknesses? Each of the discussed service models adheres to the five characteristics mentioned, possibly adhering in different ways. Within each of the service models, there may also be multiple ways to enable and deploy the service. The service model is the what, the deployment model is the how.

Many cloud services are straightforward to comprehend. For example, network as mentioned earlier. Most do not realize that the network was one of the very first types of IaaS, therefore, one of the original types of cloud. True, there are many types of services, and with that, an even greater number of ways to refer to them. In this section, we introduce the deployment models and some of the jargon. The discussion also addresses how the different deployment types are referenced, marketing names, labels, and currently used buzz words.

This section also demystifies some of the marketing hype which makes it easier to quiet the noise when participating in the often jargon-filled conversations. How is this bare metal different to a dedicated cloud? What is a public cloud? What is a private cloud and how is private different to dedicated? Is it different? Is private on-premises still considered as the cloud? Is a private cloud from a service provider also the cloud? If it is called a cloud, it must be a cloud?
