Network topology generation method and device, cloud platform and readable storage medium

The invention discloses a network topology generation method and device, a cloud platform and a readable storage medium, and belongs to the technical field of network topology management. The method comprises the following steps: receiving a leasing request initiated by a user side, and obtaining an elastic public network IP allocated to the user side; creating a VPN gateway in a virtual private cloud VPC connected with a user side, adding an elastic public network IP to an external port of the VPN gateway, and appointing the elastic public network IP as a tunnel source site address; determining a source endpoint group based on the network segment of the user side, determining a destination endpoint group based on the network segment corresponding to the destination side, and configuring the VPN gateway according to the tunnel source site address, the source endpoint group, the destination endpoint group and the destination site address corresponding to the destination side to obtain IPsec tunnel configuratio
