What is a bare metal server?
The English name of the bare metal server is Bare Metal Server, BMS. In fact, it is a physical server, which is right:
What is a bare metal server?
In fact, this name appears in public cloud services. If a virtual machine is provided in a public cloud, it is generally called a cloud server (or cloud virtual host), and if a physical machine is provided, it is generally called a bare metal server. Therefore, the name of the bare metal server is to distinguish it from the cloud server.
Bare Metal Server (BMS) is a computing service that combines the flexibility of virtual machines and the performance of physical machines. It provides you and your enterprise with dedicated physical servers on the cloud, providing core databases, key application systems, Services such as performance computing and big data provide excellent computing performance and data security. Tenants can apply flexibly and use them as needed.
The activation of the bare metal server is self-service. You only need to specify the specific server type, mirroring, and required network configuration, etc., and you can obtain the required bare metal server within 30 minutes. The server supply, operation and maintenance work is handed over to HUAWEI CLOUD, so you can focus on business innovation.
Product architecture
By combining with other services, bare metal servers can realize functions such as computing, storage, network, and mirroring installation:
- Bare metal servers are deployed in different availability zones (the zones are connected via an intranet), and the failure of some zones will not affect other zones in the same zone.
- You can establish a dedicated network environment through the virtual private cloud, set up subnets, security groups, and achieve external network links through the elastic public network IP (bandwidth support is required).
- Through the mirroring service, you can install mirrors on bare metal servers, or you can create bare metal servers in batches through private mirroring to achieve rapid service deployment.
- Realize data storage through cloud hard disk service, and realize data backup and recovery through cloud hard disk backup service.
- Cloud monitoring is an important part of maintaining the reliability, availability, and performance of bare metal servers. Through cloud monitoring, users can observe bare metal server resources.
- Cloud Backup provides backup protection services for cloud hard drives and bare metal servers, supports backup services based on snapshot technology, and supports the use of backup data to restore server and disk data.

Functional comparison of bare metal servers, physical machines, and virtual machines
Table 1 shows the comparison of bare metal servers with physical machines and virtual machines. Among them, Y means support, N means not support, and N/A means not involved.
Description:
No feature loss, no performance loss: The bare metal server has all the characteristics and advantages of a physical machine. Your application can directly access the processor and memory of the bare metal server without any virtualization overhead.

- For the network types of bare metal servers and their respective usage scenarios, please check the network .
- The internal and external service addresses of the instance, that is, the private IP address and the elastic public network IP address .
interview method
The public cloud provides a Web-based service management system (ie, management console) and an API (Application Programming Interface) management method based on HTTPS requests.
- API method
If users need to integrate the bare metal server on the cloud platform into a third-party system for secondary development, please use the API method to access the bare metal server. - Management console mode For
other related operations, please use the management console mode to access the bare metal server. If the user has registered for the public cloud, he can directly log in to the management console and select "Compute> Bare Metal Server" from the homepage.
Applicable to the scene
- Scenarios with high security and regulatory requirements The
financial, securities and other industries have compliance with business deployment, and some customers have stringent requirements for data security. The deployment of bare metal servers can ensure exclusive resource sharing, data isolation, supervision and traceability. - High-performance computing scenarios High-performance computing scenarios such as
supercomputing centers and gene sequencing require large amounts of data to process, and require high computing performance, stability, and real-time performance of servers. Bare metal servers can meet the needs of high-performance computing. - Core database scenarios
Some key database services cannot be deployed on virtual machines and must be carried by physical servers with dedicated resources, network isolation, and guaranteed performance. Bare metal servers provide users with exclusive high-performance physical servers that can meet business needs in this scenario. - Mobile application scenarios
Focusing on the development, testing, launch and operation of mobile applications, especially mobile games, with the help of Kunpeng series servers' compatibility advantages for terminal devices, a one-stop overall solution is created based on Kunpeng series bare metal servers.
