Integrity of election process will determine the integrity of democracy itself. So the election system must be secure and robust against a variety of fraudulent behaviours, should be transparent and comprehensible that voter and candidates can accept the result of election. But in history, there are examples of election being manipulated in order to influence their outcome. Anonymity of ballot should be preserved both to guarantee that voter have no proof that proves which candidates receive their votes. Architecture to manage identity and access in Multi-tier cloud infrastructure, in which most services are supported by massive-scale data centre over the internet. Multi-tier cloud infrastructure uses tier-based model from software engineering to provide resources in different tiers. In this paper we focus on design and implementation of centralized identity and access management system for the multi-tier cloud infrastructure. First we discuss identity and access management requirement in such an environment and propose our solution to address these requirements. Next we discuss approaches to improve performance of the IAM system and make it scalable to billion of users.
