System and method embodiments of centralized discovery controller (CDC) services on a switching network fabric are disclosed. Nodes on the switching network fabric are categorized into leader nodes, e.g., spine switches, and follower nodes, e.g., leaf switches. The CDC services may be divided into centralized CDC services and distributed CDC services, which have direct connections to endpoints for seamless horizontal scaling of endpoints. The centralized CDC services may be placed on a leader node, and the distributed CDC services may be placed among the follower nodes. Operations of the CDC services may be monitored. In case of a node failure, CDC services deployed on the failed node may be moved or transferred to one or more other nodes that have the same role as the failed node. Implementations of the CDC service placement embodiments enable seamless horizontal scaling for endpoints and provide capability for more visibility and monitoring of endpoint.
