Method for implementing active-active architecture on basis of distributed consistency state machine

The invention relates to a method for implementing an active-active architecture in different places of the same city. A method for implementing the active-active architecture on the basis of a distributed consistency state machine comprises the following steps that: (1) two data centers with the same data in different places in the same city establish network communication by a network switch andan optical fiber cable; and (2) clients of two data centers respectively access a distributed cluster system by a network, send data information to the distributed cluster system and receive confirmation information returned by the distributed cluster system, wherein the distributed cluster system consists of virtual machines applying by a public cloud platform, uses a deployment tool to deploy distributed cluster information and meanwhile, adopts a distributed consistency algorithm to make data information of a plurality of virtual machines at the same time point consistent. The method has the advantages of simplici
