What the editor shares today is that there are several traps to pay attention to when renting a CVM. Maybe you are no stranger to renting a CVM, or you have never known about renting a CVM. But don't worry, today the editor will explain the trap of renting a CVM with the simplest description. Let's take a look.

CVM is a simple, efficient, secure and reliable computing service with flexible processing capacity. Its management is simpler and more efficient than physical servers. Users can quickly create or release any number of CVMs without purchasing hardware in advance. Reduce the difficulty of development, operation and maintenance and the overall IT cost, so that you can focus more on the innovation of your core business. With the continuous development of cloud computing, the demand for cloud computing servers is increasing. Higher security and more stable CVM become the first choice for everyone. The process of CVM leasing still needs to be carefully chosen. In order to make our CVM rental more secure, we should pay attention to several traps:

1. False test

When purchasing a CVM, many users will turn on the testing machine for testing. However, many users report that the indicators of the test host are good, but the real business as a production system is riddled with holes. Why is that? In fact, it's very simple. The problem is the test machine. Many CVM leases test machines are specially optimized by CVM providers. Therefore, the purchase of cloud servers can not fully trust the test data of the test machine. The evaluation of real users may be more valuable.

2. Confuse the fake with the real

Main performance: in the traditional virtual space, VPS pretends to be a cloud server; tampers with the information system, maliciously enhances configuration information, and deceives users.

Virtual space, VPS and cloud servers are similar, but they are completely different. Huge differences in performance, security, and reliability.

Virtual space, also known as "shared host", is that the server has many websites, and we share the hardware and bandwidth of the server. If it fails, all the websites are inaccessible.

VPS host, that is, virtual private server, virtual private server, the server is divided into multiple virtual private server services. Each VPS can assign independent public network IP address, independent operating system, independent super-large space, independent memory, independent CPU resource programs and independent system configuration independent implementation, and so on.

Cloud converts physical server resources into virtual resource pools, and customizes the corresponding host resources from the resource pool according to the actual needs of users. To put it simply, virtual space and VPS are host-based virtualization, and cloud servers are server clusters based on virtualization.

Use virtual spaces and VPS to impersonate cloud servers, not the worst. Some illegal service providers tamper with their system information in order to make huge profits. Just last week, we received a complaint. The Hong Kong CVM provider of CVM has hundreds of processors, but the test is found to be fake! Poor performance! After testing, the host's hard disk performance is also quite "normal"! No, it means it's easy to cheat, but it's hard to cheat professional users!

3. Inferior quality

Due to the background of the CVM, the user is opaque. Users have no idea what kind of physical equipment the supplier is and how to manage the architecture and computer room of the cloud resource pool. Many manufacturers only pull a few servers, create a simple virtual, dare to sell cloud servers. In fact, the domestic market is indeed full of low-quality clouds. A considerable number of Chinese customers, but also make such a cloud.

As described above, there are several traps to pay attention to when renting a CVM. You should pay more attention to it. When choosing a CVM, users should not only consider the above points, but also choose a secure and reliable cloud service provider. Then, according to the analysis and comparison of their own needs, considering the performance-to-price ratio and the actual situation, and combining with the characteristics of the cloud service, make the best choice.
