The **Service Delivery Network** is a conceptual element within the [[Service Delivery (CSDM domain)|Service Delivery domain]] of the [[Common Service Data Model|Common Service Data Model]] (CSDM), a reference architecture developed by [[ServiceNow|ServiceNow]] that provides prescriptive guidance on service-related definitions and data modeling within the ServiceNow AI Platform. The Service Delivery Network is not a single entity but represents a set of interconnected services that enable service consumers—including end users and connected devices—to access services that providers have distributed or made available across internal, external, public, private, wired, and wireless delivery channels. In a [[Technology Workflows (ServiceNow)|Technology Workflows]] scenario, the Service Delivery Network comprises the elements that make up an [[Application Service (CSDM)|Application Service]], including [[API (CSDM)|APIs]], [[Application (CSDM)|Applications]], [[AI Function (CSDM)|AI Functions]], [[AI Application (CSDM)|AI Applications]], [[Operational Technology (CSDM)|Operational Technology]], infrastructure [[Configuration item|configuration items]] such as hosts and networking equipment, and [[Network Service Instance (CSDM)|Network Service Instances]]. Together with [[Connection Service Instance (CSDM)|Connection Service Instances]], which represent logical or physical network connections, the Network Service Instances form the core of the Service Delivery Network as part of the service dependency map. CSDM 5 expands this concept beyond traditional technology workflows to include utility, manufacturing, retail, and transportation services, where the mapping of interconnected services may focus on power provisioning, supply chain management, or other operational processes delivered to mobile, home, and office-based users with their connected devices. ![[service-delivery-network.png]]
