This article introduces the difference between the server built by virtual machine and the server bought by Aliyun and Tencent Cloud. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

In addition to certain technical requirements, other differences are quite large, mainly in the following aspects:

1. Easy to operate

The servers provided by cloud service providers have built-in mainstream operating systems, Windows genuine activation; online operating systems can be replaced; Web online management, simple and convenient; their own virtual host built in the cloud server, everything needs to be prepared, but also the lack of suitable online management tools

2. Disaster recovery backup

The underlying storage of the server provided by cloud service providers adopts distributed storage, three copies of data design, and single damage can be quickly recovered in a short time; user-defined snapshots can be configured; super cloud management platform can effectively avoid the impact of hardware failure; while self-built servers on virtual hosts often use ordinary single storage, which can not be recovered once data is lost

3. Flexible expansion

Cloud service providers not only provide servers, but also provide a variety of services, which can easily expand the server; activate CVM is very flexible and can upgrade configuration online; use load balancer online to easily expand applications; while self-built servers, it does not have the corresponding advantages, any expansion operation requires hardware expansion to meet the demand, and the cost is high.

4. Low cost

The threshold for the use of servers provided by cloud service providers is low, and there is no need for one-time large investment, purchase on demand, flexible payment, and flexible response to business changes, while self-built servers need to have more investment at one time and cannot be purchased on demand. It must be fully matched for the peak value of the business, and the one-time investment is huge, resulting in serious idle waste.

5. Security

In addition to providing multiple backup mechanisms at the data security level, cloud service providers also provide additional services such as port intrusion scanning, horse hanging scanning and vulnerability scanning; effectively protect against DDoS attacks, which can clean traffic and black holes; can effectively prevent MAC spoofing and ARP attacks; while self-built virtual servers have common vulnerabilities such as hanging horses and port scanning.

This is the difference between the server built with a virtual machine and the server bought by Aliyun Tencent Cloud. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
