What deployment method is recommended for improving VRM reliability in Huawei FusionCompute?

The recommended deployment method for improving Virtual Resource Management (VRM) reliability in Huawei FusionCompute is active/standby deployment. This approach enhances reliability by ensuring that there is a backup system ready to take over in case the primary system fails. In an active/standby setup, one node is actively processing requests while the other is in a standby mode, ready to kick in without interruption, providing a level of fault tolerance that is crucial for maintaining service availability.

The active/standby method reduces the risk of downtime and can also simplify the processes of both maintenance and recovery. When one node goes down or needs maintenance, the standby node can seamlessly take over, ensuring continuous operation of the services. This is especially important in environments where consistent uptime is critical to business operations.

Other deployment options, such as single node deployment, hybrid deployment, or active-active deployment, may not provide the same level of fault tolerance or reliability. Single node deployments lack redundancy altogether, while hybrid and active-active deployments can introduce complexity and might not ensure that there is always a reliable backup ready to take over as effectively as an active/standby model does.
