Hello All,

Thanks

Mahesh,

The biggest difference between the 2 is who is in charge of maintaining the hardware and software for providing ServiceNow.

On Prem you'd have to provide the servers, set them up, and maintain them.   All upgrades and normal maintenance would be performed by the company going the On Prem route.

ServiceNow hosted all this is taken care of.   They maintain the software and hardware which also means that they take care of any security issues as well as it's their job to do things like upgrade SSL and things like that.

The only real benefit of On Prem is that you have COMPLETE control over your data, but you have to seriously weigh that with the manpower necessary to maintain all the servers and software required to run ServiceNow on a day-to-day basis.

Also, getting support on Prem is a little more difficult than in the SAAS world.   Support techs don't have access to your system to investigate issues you raise with HI, so alternate support methods have to be scheduled (webex, etc.).

If you have to control all data that enters and leaves your instance, then on Prem is the way to go, but 99.9% of all customers can work in SAAS perfectly fine.

Hi Chris,

Using the REST API, is there a way to differentiate whether the instance you're interacting with is in cloud or on-prem?

Thanks,

Also, ServiceNow's cloud offering has a lot of automated management developed by their operations team... for instance, live replication between two geographically distinct data centers, that can be failed-over within minutes in an automated way, and automated management for moving, upgrading, growing, etc.

This can be a lot of work to re-engineer for yourselves internally, so you may lose that "high availability" architecture (more details here; https://www.servicenow.com/content/dam/servicenow/documents/whitepapers/wp-sn-advanced-high-availabi... ) and wind up doing a lot of operations processes manually.
