The statement is TRUE . Huawei Cloud makes an explicit architectural distinction between Elastic Cloud Servers and Bare Metal Servers regarding the underlying compute resources. An ECS is a virtualized compute instance. Multiple ECS instances can therefore consume resources provided by the same underlying physical host, with virtualization providing logical isolation between tenants and workloads.
A BMS, by contrast, provides exclusive access to physical compute resources. Huawei Cloud states directly that BMS users can exclusively access physical resources, whereas ECS users share those physical resources. This makes BMS particularly suitable for mission-critical systems, big-data clusters, enterprise middleware, high-performance workloads, and applications that require predictable performance or direct access to physical CPU and memory resources.
Huawei's BMS comparison also identifies Exclusive resources = Yes for BMS and traditional physical servers, but No for ECS. BMS additionally provides cloud characteristics such as automatic provisioning, VPC integration, image-based deployment, monitoring, and cloud storage while retaining physical-server performance.
Therefore, the differentiation presented in the question is technically accurate.
