10. The apparatus according to claim 7 , wherein the acts further comprise:

in response to determining that another operation type corresponding to another operation request is upgrading configuration information of the distributed consistency system, determining to permit an execution for an operation corresponding to the another operation request.

11. The apparatus according to claim 7 , wherein the acts further comprise:

acquiring a serial number of a newly added host in response to determining that another operation type corresponding to another operation request is replacing a host deployed by the distributed consistency system; and

establishing an association between the serial number of the newly added host and serial numbers of hosts not having been replaced in the distributed consistency system to form a new distributed consistency system.

12. The apparatus according to claim 7 , wherein the acts further comprise:

stopping an external service of the distributed consistency system in response to determining that another operation type corresponding to another operation request is replacing a disk used by a designated host in the distributed consistency system;

acquiring log information and snapshot data from another host in the distributed consistency system; and

resuming the external service after storing the log information and the snapshot data to a newly added disk.

13. One or more memories storing thereon computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

issuing an operation request to a distributed consistency system in a cluster and display an operating state of the distributed consistency system; and

determining deciding information for processing the operation request and sends the deciding information to an operation and maintenance control platform, wherein the deciding information for processing the operation request is determined based on data consistency and availability of the distributed consistency system, the determining the deciding information for processing the operation request including:

determining an operation type corresponding to the operation request; and

determining the deciding information for executing an operation corresponding to the operation type, wherein the deciding information for executing the operation corresponding to the operation type is determined based on an availability condition and a security condition of the distributed consistency system, the determining the deciding information for executing the operation corresponding to the operation type including:

before selecting a host from the cluster for upgrading, determining that a service of a previous host before the host is upgraded meets the availability condition,

selecting the host from the cluster for upgrading in response to determining that the operation type is an upgrading service in the distributed consistency system, and

determining to upgrade the selected host in response to determining that the service meets the availability condition.

14. The one or more memories according to claim 13 , wherein the acts further comprise:

acquiring monitoring data in a respective host of the cluster; and

collecting the monitoring data.
