What are the differences between bare metal servers and physical machines? And how to choose between them

Bare metal server What's the difference with physical machine? Bare metal server It's traditional Physical server The upgraded version of, not only has the hardware properties of traditional physical servers, but also has the characteristics of convenient, efficient, flexible, stable, and high security of cloud services. With the help of powerful computing power that allows users to experience flexibility and flexibility, it can also bring stable performance to traditional managed servers and the advantages of highly elastic resources in the cloud. The bare metal server architecture belongs to the native architecture of the hypervisor virtual service. It mainly installs the hypervisor directly on the hardware and takes over all hardware resources. The bare metal server architecture can include multiple functions such as computing, storage, network, image installation, etc. It can be deployed in multiple regions. Even if a failure occurs in a region, it will not affect other zones in the same region. At the same time, private cloud can be used to establish a private network environment; Its image service can quickly complete business deployment.

Physical servers refer to independent servers, that is, physically independent servers. The composition of the physical server includes processor, hard disk, memory, system bus, etc. It is similar to the general computer architecture, but because it needs to provide highly reliable services, it has high requirements in processing capacity, stability, reliability, security, scalability, manageability, etc.

Difference and comparison:

1. Difference between bare metal server and physical server

The bare metal server has all the characteristics and advantages of the physical machine, high performance computing power, secure physical isolation, etc. But the bare metal server is not a traditional physical machine. It is a new computing server product based on virtualization technology, which retains the elastic experience of ordinary cloud servers and the performance and characteristics of physical machines. The bare metal server enables the traditional physical machine to have automatic distribution, automatic operation and maintenance VPC's ability to interconnect and support shared storage and other clouds.

2. Difference between bare metal server and ECS

Although bare metal servers and ECS have the same advantages in automated management, flexibility, and one click installation, the biggest difference between bare metal servers and ECS is their independence and high security physical isolation. After purchasing the bare metal, you will have an exclusive physical server that is physically isolated from other tenants. This is very important for users who have requirements for the security of the core database, isolation of users with hard indicators, and high performance requirements. The bare metal server combines the independence and high physical isolation of the physical server, and has the flexibility and flexibility of the cloud server, self-service management, and more advantages, which is also the reason why most users choose the bare metal server.
