A bare metal server is a hardware device that has the characteristics of a traditional physical server and has the virtualization service function of cloud computing technology. It is a product of the combination of the advantages of hardware and software. Its essence is a cloud-based server. Compute service functions and servers that provide physical device performance. Bare metal servers can usually be seamlessly connected and compatible with other cloud services provided by cloud vendors, such as network services (such as VPC private networks), cloud database services, etc.

Bare Metal Server (Bare Metal Server) is a hardware device that not only has the characteristics of a traditional physical server, but also has the virtualization service function of cloud computing technology. It is a product that combines the advantages of hardware and software. It can provide enterprises with exclusive cloud physical servers, providing excellent computing performance and data security for core databases, key application systems, high-performance computing, big data and other businesses. This allows cloud service users to apply flexibly and use it as needed.

The essence of a bare metal server is a server that has both cloud computing service functions and physical device performance.

Bare metal servers can usually be seamlessly connected and compatible with other cloud services provided by cloud vendors, such as network services (such as VPC private networks), cloud database services, etc.

This makes it easier for bare metal servers to communicate and collaborate with users’ existing virtualized servers, and to effectively utilize cloud resources.

A certain cloud service provider has also developed an "elastic" bare metal server. The self-developed virtualization technology can solve the aforementioned virtualization performance overhead problem and can have a complete processor at the physical machine level. The characteristics feel quite powerful.

The following table can clearly see the difference between elastic bare metal servers, traditional physical servers, and virtualized servers:

What is a bare metal server

Which users are using bare metal servers?

Bare metal servers have exclusive resource characteristics. Therefore, it is very suitable for some scenarios that require high security isolation, such as banking, finance, securities and other industries. These industries have compliance requirements for business deployment, you are not allowed to share accommodation with others, and data must be physically isolated. Therefore, they are the primary customers for bare metal servers.

The second type of users are those who have extreme requirements for performance. For example, in scientific research scenarios such as supercomputing, aerospace, cosmic observation, and even high-energy physics, the amount of data they have to process is unprecedentedly huge, and the stability of the computing process is also very high. Therefore, bare metal servers are preferred.

The third type of user is game development. The online gaming business also has high system performance requirements and requires the service to be stable enough, so it also tends to use bare metal servers.

Bare metal servers began to appear in 2014, and their development time is not very long. Overall, its market size is growing, and more and more users are demanding it. Many cloud service providers, including major clouds, have stepped into the game and launched their own bare metal server products.

Main applications of bare metal servers

Bare metal servers are mainly used in situations with high sensitivity to system stability, security and high standards. First of all, because the bare metal server has exclusive resource characteristics, it is very suitable for some scenarios that require high security isolation, such as banking, finance, securities and other industries. These industries have high compliance requirements for business deployment. Cross-industry and cross-domain cloud service sharing is not allowed, and data must be physically isolated. Therefore, they are the primary customers for bare metal servers. Secondly, those users who have extreme performance requirements. For example, in scientific research scenarios such as supercomputing, aerospace, cosmic observation, and even high-energy physics, the amount of data they have to process is unprecedentedly huge, and the stability of the calculation process is also very high. Third, the game development environment. The online gaming business also has high system performance requirements and requires the service to be stable enough, so it also tends to use bare metal servers.

如何在 RHEL 9 上配置 DHCP 服务器如何在 RHEL 9 上配置 DHCP 服务器Jun 08, 2023 pm 07:02 PM

DHCP是“动态主机配置协议DynamicHostConfigurationProtocol”的首字母缩写词,它是一种网络协议,可自动为计算机网络中的客户端系统分配IP地址。它从DHCP池或在其配置中指定的IP地址范围分配客户端。虽然你可以手动为客户端系统分配静态IP,但DHCP服务器简化了这一过程,并为网络上的客户端系统动态分配IP地址。在本文中,我们将演示如何在RHEL9/RockyLinux9上安装和配置DHCP服务器。先决条件预装RHEL9或RockyLinux9具有sudo管理权限的普

Linux怎么在两个服务器直接传文件Linux怎么在两个服务器直接传文件May 14, 2023 am 09:46 AM

scp是securecopy的简写,是linux系统下基于ssh登陆进行安全的远程文件拷贝命令。scp是加密的,rcp是不加密的,scp是rcp的加强版。因为scp传输是加密的,可能会稍微影响一下速度。另外,scp还非常不占资源,不会提高多少系统负荷,在这一点上,rsync就远远不及它了。虽然rsync比scp会快一点,但当小文件众多的情况下,rsync会导致硬盘I/O非常高,而scp基本不影响系统正常使用。场景:假设我现在有两台服务器(这里的公网ip和内网ip相互传都可以,当然用内网ip相互传
