CI - Configuration Item - Which are Maintained using a Change Control Process Like Servers/DBs/JBOSS etc

Application Service-> Set of Logical and Physical CIs constitutes an App Service.An application service is a set of interconnected applications and hosts which are configured to offer a service to the organization. Application services can be internal, like an organization email system or customer-facing, like an organization website.The various CIs and the relationships between them, that comprise an application service, are stored in the CMDB.

A Sample Application Service Map-Various Logical and Physical(if Any) Constitutes Application Service and Service Now Makes Its MAP as below.

Hope This Helps.

the ci is a basic compound (table) of Configuration Item (cmdb_ci), which are built up CMDB.  each ci is also defined as a class. Application is one of CIs for CMDB.  Each ci is focus on its own scope like Application Service is focus on Business Service so it parent is Service/Business Service ci(class).  Please see its data model blow:

The following are the additional resources for you to understand

1) ServiceNow Data Model -please take a look on slide 29 for Business Service (cmdb_ci_Service), which is parent of Application Service
