Cloud-native architecture emphasizesapplication-level design and management, focusing on agility, scalability, and resilience.

Microservices,containers, andservice meshesare core cloud-native technologies.

Virtualizationis a foundational cloud technology but belongs totraditional cloud infrastructure, not cloud-native application architecture.

Therefore, the correct answer isVirtualization.

According to the Huawei HCIA-Cloud Computing documentation, specifically within the "Planning and Deployment of FusionAccess" module, the network architecture of a cloud data center is divided into distinct planes to ensure security, isolation, and efficient management. In a FusionAccess deployment, infrastructure virtual machines (VMs)—which include critical components such as the ITA (IT Adapter), HDC (Huawei Desktop Controller), WI (Web Interface), and the GaussDB database—are considered the "management brain" of the desktop cloud solution.

TheManagement planeis specifically designed to facilitate communication between management systems and all nodes within the cloud environment. In the provided scenario, the network segment192.168.10.0/24(VLAN 10) is designated as the FusionCompute Management plane. Huawei's official best practices dictate that Linux infrastructure VMs must be deployed on this plane to allow them to communicate directly with theVirtual Resource Management (VRM)node and theComputing Node Agent (CNA)hosts. This placement ensures that management traffic for desktop provisioning and resource orchestration remains isolated from general user traffic and heavy storage data flows.

In contrast, theService plane(192.168.30.0/24) is intended for the traffic of standard user applications, while theService desktopsegment (192.168.108.0/22) is reserved for the end-user virtual desktops themselves. Placing infrastructure VMs on theStorage plane(192.168.20.0/24) would be technically incorrect, as it is strictly dedicated to disk I/O and would not provide the necessary logical path to the management portal. Therefore, selecting network segment B ensures that infrastructure components are securely positioned to manage the desktop lifecycle while maintaining high availability and administrative accessibility.

In the official Huawei HCIA–Cloud Computing documentation, the core definition of virtualization centers on the abstraction of physical resources. The essence of virtualization technology is precisely the transformation of physical, hardware-based resources—such as CPUs, memory, network interface cards, and storage disks—into virtualized, logical entities. This process is facilitated by a software layer known as the Hypervisor or Virtual Machine Monitor (VMM). By creating this abstraction layer, virtualization effectively achieves the "decoupling" of the software environment (the Operating System and applications) from the underlying physical hardware.

This decoupling is a revolutionary shift from traditional computing architectures where an Operating System was tied to specific hardware drivers and physical configurations. In a virtualized environment, a Virtual Machine (VM) perceives a set of standardized, logical hardware components provided by the Hypervisor. Because the software is no longer bound to the physical machine, it gains significant mobility and flexibility. For example, in Huawei’s FusionCompute platform, this decoupling allows for features such as Live Migration, where a running VM can be moved from one physical host to another without any service interruption. This is possible because the VM's "logical" hardware remains consistent even as the "physical" host changes.

Furthermore, this transformation from physical to logical enables better resource utilization through overcommitment and sharing. Multiple logical servers can run on a single physical server, each isolated from the others. This fundamental shift is what provides the agility, scalability, and efficiency required for Cloud Computing. Without the decoupling provided by virtualization, the rapid provisioning and elastic resource scaling that define cloud services would be impossible to achieve. Therefore, virtualization serves as the indispensable technical foundation upon which all other cloud services and management layers are built within the Huawei ICT ecosystem.
