Huawei CloudFabric is designed with an open and extensible ecosystem , enabling seamless integration with multiple platforms and services across modern data center environments. This openness is a key principle in Huawei’s architecture, ensuring interoperability and flexibility for diverse workloads.

Third-party VAS interconnection (A) is supported to allow integration with value-added services such as firewalls, load balancers, and security appliances, enabling service chaining and enhanced network functionality.

Container platform interconnection (B) is critical in cloud-native environments. CloudFabric integrates with platforms like Kubernetes, allowing automated network provisioning for containerized applications through APIs and SDN control.

Cloud platform interconnection (C) includes integration with cloud management platforms such as OpenStack and Huawei ManageOne, enabling unified orchestration of compute, storage, and network resources.

Virtualization platform interconnection (D) supports platforms like VMware and FusionSphere, allowing dynamic VM-based networking and automated service deployment.

Huawei documentation emphasizes that CloudFabric supports all these interconnection scenarios to deliver full-stack, multi-platform integration , making all options correct.
