In Huawei FusionCompute, which action occurs if a host in the cluster becomes unavailable?

When a host in the Huawei FusionCompute cluster becomes unavailable, the virtual machines running on that host are automatically migrated to another available host within the same cluster. This action is part of the high availability feature that Huawei FusionCompute provides, ensuring minimal downtime and continuous service availability.

The migration process allows virtual machines to seamlessly transition to a functioning host, thereby avoiding data loss and maintaining service continuity. This capability is crucial in a cloud environment, where the availability of applications and services is paramount for user satisfaction and operational efficiency.

High availability is an essential aspect of cloud computing infrastructure, enabling systems to automatically handle failures and ensure that workloads are always processed. In this context, the other options do not align with the standard functionality of Huawei FusionCompute regarding host unavailability scenarios. For instance, automatic deletion of virtual machines or migration to a completely different cluster are not standard responses to a host failure, as the system is designed to keep virtual machines operational by redistributing them within the existing cluster resources.
