IBM has released the second Software as a Service offering in its Tivoli Live portfolio: its IT service desk. Called “Tivoli Live-service manager,” this release follows last year’s Tivoli Live-monitoring service, a SaaS app that manages the health and performance of IT resources. The IT service desk SaaS is identical to its on-premise counterpart, in that it helps clients manage their internal or external help desks, said Arthur Chiang, VP of end user services.
