What is the difference between a bare metal server and a physical machine? Selection of both servers

When we select servers, do we see bare metal servers and physical machines, including physical servers. The different names of these host products also determine the different types and functions of hosts under certain circumstances. For example, the bare metal server is called Bare Metal Server in English.

Compared with other servers, Bare metal server A physical server that is a virtual machine but does not require a virtualization layer. It runs applications and operating systems directly on the physical hardware without the virtualization layer, so it has stronger computing and storage capabilities. It can meet the requirements of high load and high concurrency applications. The bare metal server can be flexibly configured according to user needs, and users can choose different hardware configurations, operating systems and application software according to business needs. In addition, the security isolation level is relatively high.

 What is the difference between a bare metal server and a physical machine? Selection of both servers

The traditional physical server, sometimes called physical machine, is a previous generation server product. As a traditional server product, it has certain defects and deficiencies in storage and security compared with bare metal servers. In fact, we can see from the prices of the two products that the former is definitely higher than the latter.

How to choose?

As for the choice of bare metal servers and physical servers, Laozuo suggested that we should try to choose bare metal servers when they are available, because they have advantages in security, configuration stability, and subsequent flexible upgrades. If our budget is slightly insufficient, we can also choose a physical server as an alternative.

Of course, the choice of bare metal server or physical server mainly depends on our requirements and application scenarios.

1. Performance requirements

If our application needs high performance and hardware control, the bare metal server may be a better choice. The bare metal server has the characteristics of a physical server, but its performance is higher than that of a physical server.

2. Flexible adjustment

If our application needs greater flexibility and resource sharing, the physical server may be more suitable. Physical servers are usually configured in a fixed way, but they can manage and schedule resources through resource pools to meet application needs.

3. Safe and stable

Bare metal servers provide better isolation and security because they are physically more independent. Physical servers may be affected by other virtual machines or applications.

4. Cost control

In terms of cost, physical servers are usually cheaper than bare metal servers. Our applications need higher performance and security, so bare metal servers may be a better investment. If the budget is insufficient, choose a physical server.
