clanServices are modular building blocks that simplify the configuration and orchestration of multi-host services.

Each clanService:

• Is a module of class clan.service
• Can define roles (e.g., client, server)
• Uses inventory.instances to configure where and how it is deployed

!!! Note clanServices are part of Clan's next-generation service model and are intended to replace clanModules.

See [Migration Guide](../guides/migrations/migrate-inventory-services.md) for help on migrating.

Learn how to use clanServices in practice in the Using clanServices guide.
