O que é o servidor MID?
O Management, Instrumentation, and Discovery Server é um aplicativo Java que é executado como um serviço do Windows ou daemon UNIX em um servidor na sua rede local. O MID Server permite a comunicação e a movimentação de dados entre uma instância do ServiceNow e aplicativos externos, fontes de dados e serviços. Ele é essencial para muitas implementações bem-sucedidas, pois é usado com vários produtos ServiceNow, como Discovery, Service Mapping, Integration Hub, Orchestration, Cloud Provisioning and Governance, Event Management e Operational Intelligence, e pode fornecer suporte para integrações com LDAP, Active Directory e integrações de terceiros usando SOAP ou REST, veja também o video oficial no youtube.
