Data processing method, apparatus, device, and storage medium are provided, so as to improve the efficiency of data processing. The method includes: receiving a function call request; creating a function instance and a virtual network card thereof according to the function call request, to enable the virtual network card to establish communication with at least one gateway node, wherein a gateway service instance of the gateway node is attached with a virtual network card; and sending a data packet corresponding to the function instance after being encapsulated to the gateway node through the virtual network card of the function instance, to enable the gateway node to forward thereof to a virtual private cloud. Based on the virtual network card, data interactions between two instances can be realized, so as to realize the separation of function computing and gateway, and ensure the speed of cold start of function computing.
