Companies that do migrate their IAM infrastructure to the cloud will reap savings of at least 30%, says Eric Maass, CTO of Lighthouse Security Group, which sells a hosted IAM service based on IBM's platform.
"The savings come from hardware and data center space, but mostly people and time," Maass says. "You need people to build out a large IBM, Oracle or CA identity management system. That can easily be a half-million or million-dollar investment. There's a large cost avoidance with a hosted application in salaries, administration, patch management and upgrades."
