Cloud computing is generally accepted to consist of the following types of services:
Software-as-a-Service (SaaS): The provision of a hosted application for use as part of a business process. Hosting usually includes all supporting components for the application such as hardware, operating software, databases etc.
Platform-as-a-Service (PaaS): Hardware and supporting software such as operating system, database, development platform, web server etc. are provided but no business applications
Infrastructure-as-a-Service (IaaS): Only physical or virtual hardware components are provided
This policy applies to the use of all types of cloud computing services and is particularly relevant where personal data is stored.
