# Inferred Services

This table contains backend services in your environment that APM has inferred as upstream/downstream dependencies (e.g. peer services) without a fully resolved definition. Populated by [APM](https://docs.datadoghq.com/tracing.md), [USM](https://docs.datadoghq.com/tracing/universal_service_monitoring.md), or the [Software Catalog](https://docs.datadoghq.com/internal_developer_portal/software_catalog.md).
