0090 Cloud Platforms and Services

The cloud platforms and services model show that cloud computing is not so different from what we have been doing before. Cloud infrastructure and services are classified as such to show that the organization is not completely in control of the technology supporting their data and processes.

The cloud provider is the organization that provides and runs the infrastructure for a cloud service. Typically the host it offers is actually a HostCluster.

The cloud provider may offer infrastructure as a service (IaaS), in which case, an organization can deploy VirtualContainers onto the cloud provider’s HostCluster.

If the cloud provider is offering platform as a service (PaaS), an application may deploy server capability onto the cloud platform.

If the cloud provider is offering Software as a Service (SaaS) then it has provided APIs backed by pre-deployed server capability that an organization can call as a cloud service.
