To select a suitable virtual machine, the most important thing is to choose Virtual machine , which requires us to understand the virtual machine configuration provided by our website and the selected virtual machine service provider. Taking the micro subnet virtual machine as an example, this paper briefly introduces the configuration selection of virtual machine.
According to website construction:
1. Website type: for example, whether the website is static or dynamic, what website program to use, what requirements for the operating environment, and whether a specific environment needs to be configured will affect the selection of operating system and storage mode.
2. Website visits: The average daily visits and the average number of people online at the same time will affect the choice of CPU, memory and bandwidth.
3. Website data size: how large the website's current data is and whether it will grow rapidly in the future will affect the choice of hard disk.
4. Target users of the website: whether the website is for national users or local users will affect the choice of computer room lines.
Combined with various configuration parameters of virtual machine:
1. CPU: CPU represents the computing power of the host. If the website traffic is large and there are many dynamic pages, it is recommended to choose a CPU with more than 2 cores.
2. Memory: Memory is also an important factor in determining the speed of website opening. The larger the memory, the larger the available cache, and the faster the opening speed. Windows operating system does not support 512MB memory selection.
3. Hard disk: The size of the hard disk should be determined according to the size of the website, and the remaining space should be considered when selecting. In addition, the I/O reading speed of the hard disk directly determines the file reading speed. The disk reading speed of the virtual machine is much faster than that of other websites, which is generally enough.
4. Bandwidth: The virtual machine has no traffic limit, so bandwidth is mainly considered. Bandwidth is a direct reflection of a website's opening speed. The larger the bandwidth, the faster the access speed. For websites with a large number of visitors, it is recommended to select large bandwidth.
5. Operating system: The choice of operating system is related to personal familiarity and specific conditions of the website. If you know which operating system better, you should choose which operating system. In addition, the windows system supports asp programs better, but takes up more memory, while the Linux system supports php programs better, saving more memory, and some programs may only support a certain operating system.
6. Machine room lines: There are three virtual machine rooms in Hong Kong, Beijing and Jiangsu, all of which are BGP multi line machine rooms with fast access speed and interconnection. If you do not need to file a case, you can choose Hong Kong virtual machine.
If you cannot determine the virtual machine configuration after reading the above introduction, you can choose Neutrino network Configure a lower virtual machine for testing. If you are using ECS , found that you can not meet the requirements, you can upgrade it at any time. The normal operation of the website will not be affected during the upgrade process. The upgrade is usually completed in 3 minutes.
