What are the metrics used to measure the technology of CVM? 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.

Different websites have different requirements for the performance of CVM. The configuration of CVM, such as CPU, number of cores, memory capacity, disk read and write speed, network bandwidth, operating system, etc., is the measure of performance metrics. Generally speaking, the higher the configuration, the stronger the performance of the CVM.

CPU and memory

When executing instructions such as serving web pages, running database queries, or processing computing commands, the number of CPU kernels affects how many concurrent instructions can be executed, and CPU architecture and functions also affect the speed of instruction execution. The amount of memory leased by the server affects the speed at which the server processes commands. More memory is required when dealing with more complex and multiple commands.

For example, dynamic e-commerce sites, database servers, etc., need to run a variety of queries and retrieval against the database, larger memory will give you a higher performance advantage. In the aspect of disk reading and writing, using solid state disk (SSD) and configuring RAID disk array can effectively increase data reliability and read / write performance.

Bandwidth and system

Bandwidth determines the level of network communication: the greater the bandwidth and the faster the speed, the faster the customer will open the website. In terms of cloud host operating systems, the most popular systems are Windows, Linux and UNIX systems, each of which has its own advantages. The differences in processing mechanisms of different operating systems may lead to differences in server system performance.

If you want to rent a CVM to achieve high availability, the prerequisite is to maintain good network resources and circuit supply support, which puts forward high requirements for the computer room construction and operation and maintenance management of cloud service providers. In order to ensure the continuous and normal operation of the equipment and lines in the computer room, the temperature and humidity of the environment and the management of disaster preparedness must be strictly controlled to ensure 24-hour safety monitoring.

In addition, in the increasingly severe network security situation, ddos, virus software, phishing attacks are rampant, and the network security capability and technical level of service providers will also directly affect the performance of CVM.

After reading the above, have you mastered the method of measuring the technology of the cloud server? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
