A deployed service is called a service application in SharePoint

Services that are deployed are named service applications. A service application provides a resource that can be shared across sites throughout a farm, and can be accessed by users through a hosting web application. Service applications are associated to web applications by service application connections. Some services can be shared across farms.

Service Applications are managed in Central Administration, Application Management page - and through using several different PowerShell cmdlets.
