In this era of rapid development of Internet information, it has become a trend for enterprises to go to the cloud. On this basis, Huawei Cloud Host has also quickly seized the market and become a leader in the cloud industry. Today, most enterprises and institutions are gradually transforming to the cloud, and traditional servers are no longer used on the basis of IT. According to the survey of the survey organization, only 5% of the organization's users rely on traditional servers, while 95% of the users' needs are turned to virtual machines. With regard to the rise of the virtual machine industry, especially the influx of Huawei virtual machines, traditional physical servers have lost their competitive advantages. What are the disadvantages of traditional physical servers compared with Huawei VM? Many people still don't understand it. Today, Micronet will take you to understand it.
1. Compared with Huawei VM, traditional physical servers are too expensive
For some large-scale enterprises, the purchase of servers involves inquiry and purchase, including subsequent parts damage, replacement, daily maintenance and many other links. Any link is time-consuming and laborious, and the purchase cost is very high, which requires a lot of manpower costs; Compared with Huawei VM, the price gap is too big. It is difficult for traditional physical servers to find low configuration servers. Even low configuration servers will cost tens of thousands of yuan more. However, their own resources are relatively limited, resulting in a huge waste of resources. Hosting physical servers also have to bear additional hosting fees, bandwidth fees, etc. The total cost is calculated based on the server life of up to five years, The annual cost is also tens of thousands of yuan.
2. It is more difficult to operate than Huawei VM
Conventional enterprise IT architecture requires a large number of professional and technical personnel for operation and maintenance, which is as expensive as purchasing maintenance. When the network is normal and the equipment is running normally, it is better. After all, it can be remote. Data upload and service configuration can be carried out through remote. But once the network or equipment fails, the server will be immediately paralyzed, which is a big difference from Huawei virtual machine; If the equipment needs to be restarted in case of failure, or contact IDC staff to assist in power-off and restart, or drive to the computer room at midnight to restart, it is unknown how painful it will be; Considering the cost, traditional IDC usually adopts dual line access. Any failure of a line will have a certain impact on the enterprise.
3. Configuration upgrade is much more difficult than Huawei VM
In the same service provider, it is difficult for traditional servers to find complete services. The biggest disadvantage of hardware servers may be that it is difficult to upgrade. The commonly used resources to upgrade are CPU, memory and disk. Disk and memory are relatively good. It is a big deal to go to the computer room to open the chassis and install memory modules and hard disks, but CPU expansion is basically impossible unless a new machine is purchased. In terms of bandwidth of traditional IDC, due to the limitation of total bandwidth, the number of bandwidth upgrades is often limited. Compared with the physical server, Huawei VM is much more convenient in this regard.
4. The security of traditional physical servers is not as high as that of Huawei virtual machines
In traditional IDC, it is difficult to prevent MAC spoofing and ARP attacks. Cleaning and black hole devices need to be purchased additionally, which is expensive; There are many problems, such as vulnerability hanging horse and port scanning; Additional purchase is required to deploy various security measures; Basically, it is impossible to control the access of multiple users to multiple servers, so Huawei VM is still stronger than traditional physical servers in this regard.
Now the traditional servers are gradually eliminated by the virtual machine, which is also the reason why more and more enterprises really feel the huge advantages of cloud computing. Perhaps the market choice is the best reason. The rapid transfer of enterprises to the cloud not only has practical benefits, but also lays the foundation for future development, which is also witnessed by the occurrence of the micro network.
