Scientific research is at the heart of every European University. Nowadays, such research is no longer an isolated activity, but has evolved into extensive collaboration between networks of researchers in multiple countries. With the capabilities of the internet to connect not only people but also resources, sciences have evolved into e-Science. Virtual Organisations (VOs) have emerged as the organisational form of these networks of people and resources. Broadly defined, Virtual Organisations enable groups of people to share a set of resources. Activities aiming to support VOs to use AAI (Authentication and Authorization Infrastructure) facilities in order to share their resources were already initiated during previous GÉANT projects. Providing ready-to-use AAI infrastructure will be the next step in order to enable more VOs to share resources with the R&E end-user community by using eduGAIN [eduGAIN]. In the last quarter of 2014, GÉANT project has started investigating a possibility to provide services to support AAI requirements of Virtual and Collaborative Organisations. The activity is ongoing and currently is in a stage of building the platform for service offering and preparing the business case with the aim to deliver a Virtual Organisation Platform as a Service - VOPaaS offering.
