Infrastructure as a Service (IaaS) is one of the three fundamental service models of cloud computing alongside Platform as a Service (PaaS) and Software as a Service (SaaS). As with all cloud computing services it provides access to computing resource in a virtualised environment, “the Cloud”, across a public connection. In the case of IaaS the computing resource provided is specifically that of virtualised hardware, in other words, computing infrastructure. 

The services provided to several user communities are accessible through the eduGAIN, granting European users more streamlined access to its VMs. eduGAIN /link edugain.org/ facilitates the mutual use of services by users across national borders, ensuring the secure exchange of authentication and authorisation data.
