You get started with Service Mapping by configuring roles, credentials, and MID Server connections.

Setting up Service Mapping is the first
stage in the Service Mapping
workflow.
Figure 1. Service Mapping workflow   

Service Mapping is part of the ServiceNow AI Platform and deploys some of its
platform-wide mechanisms and features. At the same time, there are some configurations that
are specific to Service Mapping only.  
Warning:  
The Service Mapping setup for the Advance Release is different from the standard Service Mapping setup.  
Perform the following tasks in the exact order they are listed below:

1. [Request Service Mapping](https://servicenow-prod.fluidtopics.net/4wdymt6ZnC2Ns0MgK6ME2A "Service Mapping is available under the ITOM Visibility subscription and requires activation by ServiceNow personnel.").
2. [Install Service Mapping Plus](https://servicenow-prod.fluidtopics.net/T3Mmx4m4c5D6DXOMfgfNNg "You can install the Service Mapping Plus application (sn_sm_scoped_app) if you have the admin role. The application installs related ServiceNow Store applications and plugins if they are not already installed.").
3. Install and configure MID Server. MID Servers, which are located in the enterprise private network, facilitate communication between servers on the network and some ServiceNow applications, such as Service Mapping, and Discovery. For more information, see [MID Server configuration for Service Mapping](https://servicenow-prod.fluidtopics.net/zWlPCWfb7dE865TT7wtHHA "Configure Service Mapping and MID Servers to work together.").
4. Verify that [Discovery](https://servicenow-prod.fluidtopics.net/KsnfyrlyH_DC7m3FpY0cZg "ServiceNow Discovery is an automated process that continuously scans and identifies all the components within the IT infrastructure. It plays a crucial role in maintaining an accurate and up-to-date CMDB 360 with the information it finds.") is set up and runs horizontal discovery as expected.
5. Configure [credentials required for host discovery](https://servicenow-prod.fluidtopics.net/9wrINqajrHPIWmwJQejr1g "There are credentials and permissions that Service Mapping requires for discovering hosts.").
6. Configure credentials required for Service Mapping to access applications inside your organization private network. See [Prerequisites for performing top-down discovery using Service Mapping](https://servicenow-prod.fluidtopics.net/20BFFRIMDaojk1En5RNucg "Learn about credentials, users, and user permissions you must configure to let Service Mapping access and discover applications inside your organization private network.").
7. If your organization network contains load balancers running on a Linux host, [create a discovery behavior for load
   balancers](https://servicenow-prod.fluidtopics.net/h0wFcwr83fTy7TpSjcOUIg "If your network uses load balancers running on Linux hosts, create a discovery behavior to ensure that Service Mapping and Discovery discover them correctly.").
8. Grant the following Service Mapping roles to relevant users:

   service_mapping_admin

   :   Sets up the Service Mapping application. Maps, fixes, and maintains service instances. Also performs advanced configuration and customization of the product. Assign this role to application administrators.

   service_mapping_user

   :   Views maps for operational service instances to plan change or migration, as well as analyze the continuity and availability of services. Assign this role to application users.

   sm_app_owner

   :   Provides information necessary for successful mapping of a service instance. Once a service is mapped, this user reviews the results and either approves it or suggests changes. Assign the
       sm_app_owner role to users who own service instances and are familiar with the infrastructure and applications that make up the services.

9. [Verify that Service Mapping is set up properly](https://servicenow-prod.fluidtopics.net/9lEex6WJ4vU_VRL6xY04Tg "Before you start mapping application services, verify that you configured MID Servers to discover application services and provided all the necessary host and application credentials.").
10. If your organization has a ServiceNow deployment with customized Discovery or CMDB attributes, perform additional configuration described in [KB0647574: Preparing customized ServiceNow deployments
    to work with Service Mapping](https://support.servicenow.com/nav_to.do?uri=/kb_view.do?sys_kb_id=334cd265db4a4fc0d7e37aa31f9619f7&sysparm_stack=&sysparm_view=).
{#service-mapping-setup__ol_kmt_n4x_ss}

In addition to the obligatory setup configurations described here, you may need to perform
additional configurations after you complete the initial mapping process. For more
information, see [Advanced Service Mapping configuration](https://servicenow-prod.fluidtopics.net/wseC861AeyTvE10F0aIv8g "Fine-tune Service Mapping collaboration with other components and modules as well as customize data display in service instance maps.").
