This document discusses strategies for deploying an identity and access management system (IAM) using a software as a service (SaaS) provider. It identifies business and technical challenges that arise when an IAM system is moved outside of an organization's private network perimeter and offers solutions to address them.
Every medium to large organization can benefit from an IAM system. Many organizations are interested in moving some of their IT infrastructure from private data centers to "the cloud" -- which often is short-hand for software as a service (SaaS). It follows that many organizations will be interested in moving their existing IAM systems or deploying a new IAM system in a SaaS model.
