balance between. More discussion of system performance and architecture is also being carried out around consistency and availability.2) engineering practices for OpenStack, Swift and CapIn contrast to cap theory, OpenStack's distributed object storage System, swift, satisfies availability and partition tolerance, without guaranteeing consistency (optional), but achieving eventual consistency. Swift if the

The Virtual Machine high availability configuration allows the Virtual Machine System to provide 24x7 services. When a problem occurs on the host machine where the virtual machine is located, the Failover function automatically migrates the virtual machine to other nodes in the cluster, in this process, the virtual machine service continues, and two ping packets are dropped at most. The following describes
