Traditional identity approaches in a cloud environment that demands scale and openness, suffer from a number of limits, especially when the enterprise uses multiple cloud service providers (CSPs) and user credentials are not shared with other providers. Multiple attempts to solve this problem have been proposed like federated Identity that has a number of advantages, even though it suffers from many challenges that are common to new technologies. Keeping business systems data safe and protecting the identity has never been more difficult to achieve; therefore, in this paper we tackle federated identity, its components, advantages, disadvantages, then we propose a number of useful scenarios to manage identity in the cloud.
