TCI REFERENCE ARCHITECTURE WHITEPAPER Foreword

Foreword

Welcome to the Cloud Security Alliance’s “Trusted Cloud Initiative Quick Guide,” Version 1.0. This is one of many research deliverables CSA will release in 2011. Trusted Cloud Initiative is a comprehensive approach for the architecture of a secure, identity-aware cloud infrastructure. TCI leverages four industry standard architecture models: TOGAF, ITIL, SABSA, and Jericho. This approach combines the best of breed architecture paradigms into a comprehensive approach to cloud security. By combining business drivers with security infrastructure, TCI increases the value proposition of cloud services within an enterprise business model.
