The invention discloses a low-cost cloud host intelligent fault instantaneous switching method. It includes the following steps: (a) the user sends a service request to the cloud management platform; (b) the cloud management platform sends the service request to a cloud host, and then puts the virtual disk of the cloud host in the cloud storage system; (c) When the cloud host fails, the cloud management platform will pass the configuration information of the faulty cloud host to a new host; (d) the new host is connected to the cloud storage system, and is searched and connected to the cloud storage system according to the configuration information of the faulty cloud host. The virtual disk of the failed cloud host; (e) Create a new virtual machine on the new host; (f) The cloud management platform points the access routing information from the failed cloud host to the newly created virtual machine to complete the failover. The invention has high utilization rate of resources, fast fault recovery speed, automatic intelligent control, strong reliability, unlimited number of fault recovery without manual intervention, and strong disaster tolerance.

The invention discloses a background framework method, system, computer device and storage medium of aggregation payment, comprising: obtaining transaction information sent by a client, the transaction information includes the location information of the client; and distributing the transaction information to A trading node that has jurisdiction over location information, where the trading node is a trading center in a designated area in the distributed trading system; according to the matching channel gateway of the trading node in the channel docking layer that has established a connection relationship with the trading node in advance, through the selected The specified channel gateway sends the transaction request in the transaction information to the transaction object for processing; obtains the processing result of the transaction object, and transmits the processing result information to the client. The present invention uses distributed transaction nodes The transaction data is processed to make payment processing data faster, and the distributed transaction centers are independent of each other, with strong data isolation, low node coupling, and strong system scalability.
