1. A computer network discovery system comprising: a database disposed within a remote network management platform; and a computing system disposed within the remote network management platform, wherein the remote network management platform manages a managed network, and wherein the computing system is configured to: transmit first instructions to a first server device, wherein transmitting the first instructions to the first server device comprises logging on to the first server device using account credentials related to the managed network, wherein reception of the first instructions cause the first server device to obtain first configuration and operational information for a first plurality of services leased to the managed network, wherein the first configuration and operational information for the first plurality of services are obtained by way of application programming interfaces, wherein the first server device is not in the managed network or the remote network management platform, receive, from the first server device, the first configuration and operational information for the first plurality of services, store the first configuration and operational information for the first plurality of services in a first set of tables of the database, transmit second instructions to a second server device, wherein reception of the second instructions cause the second server device to obtain second configuration and operational information for a second plurality of services leased to the managed network, wherein the second server device is not in the managed network or the remote network management platform, and wherein the first plurality of services and the second plurality of services are offered by different entities and have different configurations, receive, from the second server device, the second configuration and operational information for the second plurality of services, and store the second configuration and operational information for the second plurality of services in a second set of tables of the database, wherein the first set of tables and the second set of tables have tables in common that store parts of both the first configuration and operational information for the first plurality of services and the second configuration and operational information for the second plurality of services.
