Today, I will talk to you about the parameters of the CVM, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Cloud server (ECS) is a basic cloud computing service. There is no need to purchase hardware equipment in advance to use the CVM. In the process of use, you can expand the disk capacity and increase the bandwidth at any time as the business expands. Resources can also be released at any time to save money.

Let's first understand the basic concepts in CVM.

Example: refers to the virtual computing environment. Instance specification: refers to the different configurations of the instance, including vCPU cores, memory, network performance, etc. Instance specifications determine the computing and storage capacity of ECS instances.

Image: refers to the template for the running environment of an ECS instance, which generally includes the operating system and pre-installed software. The operating system supports multiple Linux distributions and different Windows versions.

Block storage: includes elastic block storage based on distributed storage architecture and local storage based on physical machine local hard disk. Snapshot: refers to a backup of data stored in a block at a certain point in time.

Security group: composed of instances with the same protection needs and mutual trust in the same region, it is a virtual firewall that is used to set network access control for different instances.

SSH key pair: remote login verification method for Linux CVM instance. You can also choose to log in to Linux instance using username and password authentication.

IP address: includes private network IP or private IP for private network communication, and public network IP for accessing Internet. Elastic public network IP: a static public network IP address that can be repeatedly bound or unbound with an instance.

The main reference factors for selecting the configuration of CVM are: CPU, memory, hard disk, bandwidth, line, operating system and region, etc.

CPU represents the computing power of CVM. If the website traffic is large and there are more dynamic pages, it is recommended to choose CPU with more than 2 cores. The configuration of CVM provided by current cloud service providers can be increased at any time. When you feel that your business volume has increased and you need more computing power, you can directly expand your resources on the official website.

Memory is not only a transit station for data, but also an important factor that determines the speed of opening a website. the larger the memory, the larger the available cache, the faster the opening speed. According to the scale of the website to choose the appropriate configuration of the space, if it is a general personal blog or enterprise display website, you can choose a smaller one, if the mall category, news category will be relatively larger space.

The hard disk is the place to store data, the size of the hard disk should be determined according to the data size of the website, and the remaining space should be taken into account when building the station. In addition, the reading speed of the hard disk directly determines the reading speed of the file. The reading speed of the hard disk of the cloud server is much faster than that of other websites, which is generally sufficient.

After reading the above, do you have any further understanding of the parameters of the CVM? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
