The statement is FALSE . Although an ECS group does logically organize ECS instances, its placement behavior is the opposite of what the second sentence states. Huawei Cloud ECS groups support the anti-affinity policy , which is designed to place ECS instances belonging to the same group on different physical hosts .
Anti-affinity is an availability and fault-isolation mechanism. If multiple application instances were placed on one physical server, failure of that host could simultaneously disrupt every application instance. Distributing the ECSs across different hosts reduces this correlated-failure risk and improves service reliability, high availability, and disaster tolerance.
Huawei's ECS documentation explicitly states that ECS groups support the anti-affinity policy and that ECSs in an anti-affinity group are deployed on different hosts. When an existing ECS is added to such a group, Huawei Cloud may even reallocate its host so that the placement requirement can be maintained.
Therefore, the first proposition—an ECS group logically groups ECSs—is valid. However, the assertion that ECSs in that group are created on the same physical server by default contradicts the anti-affinity design. Since the overall statement contains this incorrect condition, the correct answer is FALSE .
