In this paper the authors present a novel architecture to manage Identity Access Management (IAM) in a multi-tier cloud infrastructure, in which most services are supported by massive-scale data centers over the Internet. Multi-tier cloud infrastructure uses tier-based model from software engineering to provide resources in different tires. In this paper the authors focus on design and implementation of a centralized identity and access management system for the multi-tier cloud infrastructure. First, they discuss identity and access management requirements in such an environment and propose their solution to address these requirements. Next, they discuss approaches to improve performance of the IAM system and make it scalable to billions of users. Finally, they present experimental results based on the current deployment in the SAVI testbed.
