A Logical Group acts as a container for Configuration Items that logically groups them into whatever grouping you prefer. This can be by geographical location, business service, management group, discipline or any custom grouping. Logical groups are best used for CI’s that contribute to multiple services. For example, your core network switches and routers could be added to a Logical Group called Core Network. Then, all you have to do is link the appropriate Service Groups to the Core Network Logical Group, without the need to link each of it’s CI’s to each Service Group individually. In addition to organization, logical groups also have the following usage and impact on other aspects of your configuration.
- Permissions – User Groups linked to logical groups determine the access to assets that users within the groups are assigned.
Service Groups are similar to Logical groups, but act as a higher-level container for Logical Groups and CIs. Create your service groups to represent the devices and assets that supports a defined business service. For example: Exchange, CRM, website.
Service Groups are Logical Groups of networked assets that contribute to client-facing services such as email, CRM, or financial applications. When defining services, it is recommended that you start with what your users consider to be the most critical services provided by IT.
