Though non-hosted solutions are not the primary focus of ServiceNow due to product and strategy considerations, non-hosted solutions are supported and there are several customers using on-premise installations rather than the "usual" SaaS approach of ServiceNow.This thread is for questions (and answers, of course) regarding these non-hosted solutions.Topics in this thread may include depending on interest of the group:

• reasons why you should want on-premise rather than SaaS
• things to consider when designing an on-premise solution (legal, requirements, risks etc.)
• topics regarding sizing, implementation and operation of an on-premise solution
• issues or things to consider when migration to or from an on-premise installation (coming from or going to SaaS)
