In an FJcloud-O environment, PRIMECLUSTER can be used on the virtual servers that are built within the same availability zone (hereinafter AZ). The mirroring among servers of Global Disk Services (hereinafter GDS) is used to take over the data between the virtual servers.
Compared to auto-scaling or automatic failover, PRIMECLUSTER provides the following advantages:
The time to switch the standby virtual server from the operational virtual server is reduced because the standby VM is switched from the startup status of OS when a failure occurs in the virtual server.
The standby virtual server can be switched with monitoring the operational application when a failure of the operational application occurs.
