In this study we have surveyed the various sustainability models that could accompany a production deployment of the AARC CILogon-like TTS pilot system. This system and its close derivatives are being piloted in major RIs and e-Infrastructures, and can bridge the gap that currently exists between institutional user identities, R&E identity federations, and the non-web compute, cloud, and data services and brokering that use client certificates, such as those in EGI, PRACE, and cloud-based data transfer services.

This document is a draft for discussion, and should not be interpreted as a statement by AARC or any of its partners until is has been approved. We do invite comments to this document.
