Is there any difference between an ordinary server and a cloud server? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

As a new generation of Internet service hosting platform, cloud servers are very different from traditional ordinary servers in terms of essence, origin and external performance.

Virtualization technology

Virtualization is one of the main supporting technologies in cloud computing. CVM is composed of scale-level underlying servers through intensification and virtualization to build a cloud resource pool, and then allocate computing resources from the resource pool. Ordinary servers are physical devices that actually exist, and we can also use virtualization technology to divide a large number of virtual dedicated servers, that is, the vps that we used to use before.

Distributed storage

The difference between a CVM and an ordinary server lies in the storage method. The CVM uses distributed storage, which is characterized by good scalability, high performance and high reliability. It can achieve real-time multi-copy disaster recovery without a single point of failure, can effectively avoid a variety of failures, and supports the elastic scaling of storage resources, and enables the CVM to have functions such as hot migration.

However, ordinary servers can not achieve distributed storage, and in the event of hardware failure, data security will face serious risks such as loss, damage, or even unable to find it. Therefore, enterprises usually deploy RAID10 array security strategy, but this requires high costs and costs such as hardware purchase, which increases the financial burden of the company.

Compared with ordinary servers, CVM has the following characteristics:

1. Price advantage: through the advantage of scale and cluster, we can pay for it on demand to further reduce the customer cost.

2. High reliability: integrate the unified management of high-performance servers and high-quality network resources, and introduce advanced technologies such as CVM HA.

3. Convenient management: operations such as activating the CVM and redoing the system can be operated in the background without too much operation by the customer.

4. High stability and convenient expansion: the security and stability of CVM can be ensured through distributed management, and it can be upgraded quickly and flexibly online.
