ServiceNow model in ServiceNow

[PhilippeH]

Dear community,

I would like to create ServiceNow CIs in ServiceNow and I am wondering what was your experience about it.

Some companies create a business application per module (Incident Management, change Management, ...), which make a lot of business apps. Then some use the "Architecture type" field to differentiate the ServiceNow Platform from the modules. Could you please share your experience on that or maybe there is recommanded modelisation ?

Thanks in advance,

Philippe

Thanks Mathew for adding more details to Ravindranath's solution. I do appreciate. I understand this approach and would like to know your opinion about this one : create one business app for ServiceNow Platform and create the other modules (like incident management) as Application services linked to ServiceNow Platform business application.

Hi Philippe, 

Mark Castoe from ServiceNow recently published an article on 'What is a Business App'. Highly recommend you check that out https://www.servicenow.com/community/apm-articles/what-is-a-business-application/ta-p/3071106

For your specific question I can provide some insight. You would create the following:

1. Business App for the Platform with Architecture Type = Platform Host

2. Business App for each module/platform app (as long as they are distinct enough to be worth tracking - see Mark's article for help there) with Architecture Type = Platform Application & Platform = App from 1.

3. Assuming there is a DEV, QA, PROD environment for the application and no location-specific deployments, you would create DEV, QA, & PROD App Services for the Platform AND for each module. 

4. Create the appropriate relationships between the module app services and the platform app services to reflect that the platform deployment contains the module deployments. 

Using the easy example of ServiceNow as the platform, this is a screengrab for how it looks in CSDM 4.0
