A network topology subgraph associated with each computing device is generated. A placeholder for an unresolved connection is generated within the network topology subgraph associated with each computing device. Network mapping information associated with each computing device from the respective dependency agent is processed. The unresolved connection is resolved across the network topology subgraphs associated with each computing device in real-time by processing matching network mapping information from each computing device. An updated network topology subgraph associated with each computing device is generated by replacing the unresolved connection with a resolved connection. ## Claims ### Claim 1 A computer-implemented method, executed on a computing device, comprising: deploying a first dependency agent on a first computing device within a first site of cloud computing resources and a second dependency agent on a second computing device within a second site of cloud computing resources within a cloud computing environment;
