"Finding a clean way to deal with that has been a little bit challenging, but that is really on the periphery," Lille says. "What we are working though is creating near real-time integration between ScienceLogic and the ServiceNow asset database."

Probst points to a final caveat: Failure to cultivate mature service management processes. Lack of progress on this front will hinder the effectiveness of IT service management tools, cloud-based or otherwise.
