Bare-metal cloud services provide direct access to dedicated physical hardware, significantly enhancing computational power, disk I/O, and network I/O performance. To effectively manage physical resources, bare-metal typically relies on specialized cloud management platforms. However, the existing management architecture still faces significant bottlenecks. These bottlenecks include slow and cumbersome deployment processes, inadequate security isolation that exposes the system to potential vulnerabilities, and limited scalability that fails to meet dynamic and evolving demand. Therefore, optimizing the management architecture to improve deployment efficiency, security, and flexibility has become a key challenge for bare-metal cloud services. This paper proposesNBBM(NebulaMatrix Bare Metal), an innovative bare-metal cloud management platform architecture designed to restructure the management of bare-metal servers in OpenStack. To simplify the complexity of bare-metal cloud management and significantly improve the overall system efficiency,NBBMadopts the following technologies: an architecture that thoroughly decouples compute and storage, a distributed management system based on SmartNIC technology, and a high-performance cloud storage interconnect solution relying on SmartNICs. These technological innovations enable theNBBMarchitecture to provide a more secure and efficient cloud service management solution. Extensive experimental results demonstrate that theNBBMplatform achieves minute-level deployment and delivers at least a 12× speedup (approximately 92% reduction) over widely used methods, while ensuring secure and flexible access to storage resources without compromising performance.
