In an embodiment, a computer-implemented method for dynamically exchanging runtime state data between datacenters using a controller bridge is disclosed. In an embodiment, the method comprises: requesting, and receiving, one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts; requesting, and receiving, one or more second runtime state data from one or more physical sharding CCPs controlling one or more physical sharding hosts; aggregating, to aggregated runtime state data, the one or more first runtime state data and the one or more second runtime state data; determining updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data; and transmitting the updated runtime state data to the logical sharding CCPs and physical sharding CCPs.
