Figure 1 Architecture of SOM
Self-Service provides the UI for CMDB, and CMDB provides the data resources to SOM. But when
operating in Service Desk, Service Desk is responsible for communication with Self-Service Management
to verify and exchange user data.
These components are described in the following sections.
Service Desk
Service Desk provides a web-based interface for SOM users to complete various process operations in
the SOM module. Service Desk users have a self-service account in IMC (a self-service account is used
to log in to the IMC components that have an independent login page, such as SOM and GAM).
The types of functions provided by Service Desk are as follows:
• Management and maintenance—These functions include user and account management,
operation log management, and process template and CMDB custom management.
• SOM—These functions provide the basic capabilities for process and task viewing and execution.
Self-Service management
The Self-Service Management component provides the data access interface for the IMC user resources.
The Self-Service Management component is deployed based on the IMC platform and adds account
management and account group management functions in addition to the user management functions
that were available in previous versions of IMC. The account information includes the account name,
password, permissions, and account group information in addition to basic user information.
The Self-Service Management component does not provide any configuration management interface.
After being deployed, the component acts as an independent background process.
The account group in IMC is a set of the permissions that users have for various functions. An account can
belong to multiple groups. The permissions of an account consist of the permissions of the account
together with the permissions of all the account groups that the account belongs to.
Figure 2 is an
example of the account group settings for a particular account.
