Essentially there are 4 levels of Cloud Hosting
- Infrastructure-as-a-Service – IaaS
- Platform-as-a-Service – PaaS (aka Private Cloud)
- Cloud Servers
- Software-as-a-Service – SaaS
IaaS is the lowest level Cloud offering. This is where preconfigured hardware and storage is provided via a virtual interface or Hypervisor. No operating system in provided. Amazon is an example of IaaS.
PaaS (Private Cloud) goes a stage further and incorporates the operating system and associated utilities for managing the environment.
Cloud Server Hosting is the provisioning of virtual servers in a high availability and scalable environment with no single point of failure.
SaaS provides the complete solution on demand including the software applications. For example
