Federation technology has become a very important connective technology that enables efficient distributed identity management (IdM) and enhanced convenience for users. The trend toward outsourced applications and more collaboration between business partners strains the capabilities of traditional IdM technologies. The industry is responding to growing demands by offering federation in a range of delivery models that includes open source, identity federation as a hosted service, as well as on-premises software form factors. While federation implementations grow at a healthy rate, the industry continues to address barriers to further adoption.
