Regardless of price and usage threshold, cloud server CVM is better; from the perspective of cost performance and ease of use, lightweight application server is better. Lightweight servers are cost-effective, and the price of this configuration is beyond the reach of cloud server CVM. Tencent Cloud Encyclopedia will explain in detail the performance differences between Tencent Cloud's lightweight application servers and cloud server CVMs, CPU processor model differences, mirror system differences, public network bandwidth comparisons, price comparisons, server upgrade and upgrade differences, and applicable crowd application scenarios.
The difference between lightweight application server and cloud server CVM
There is a difference between Tencent Cloud's lightweight application server and cloud server CVM, otherwise Tencent Cloud would not need to launch two cloud servers. The cloud server CVM is a professional-grade cloud server of Tencent Cloud, which is suitable for any usage scenario, but not all application scenarios require a professional-grade cloud server. For light-weight applications such as corporate official websites, personal blogs, cloud development and testing, and WeChat applets, a light-weight application server can handle them. There is no need to choose cloud server CVM at all. The unique application image of the lightweight server can build WordPress, pagoda panel, LAMP, Node.js, Typecho, etc. with one click. It can be used out of the box, which not only saves time and cost, but also saves the price for users due to the high cost performance of the lightweight server cost. If it is a high-concurrency website, large-scale game, complex distributed cluster application, video codec, big data analysis, machine learning, deep learning and other usage scenarios, the cloud server CVM must be the first.

1. Performance difference between lightweight server and cloud server
The lightweight application server has a favorable price, but is it poor in performance? No, Tencent Cloud’s official documentation clearly states the performance difference between the cloud server CVM and the lightweight application server: Compared with the standard cloud server CVM of the same specification, the CPU and memory performance of the lightweight application server at the same level as it. As shown below:
Note: The lightweight server has similar performance to the standard cloud server CVM, and the cloud server CVM instance here refers to the standard cloud server. Cloud server CVM has a variety of specifications, such as standard type, computing type, GPU type, high IO type and big data type, etc. The CPU and memory performance of lightweight application servers and standard cloud servers are on the same level.
2. Differences in main frequency and turbo frequency of CPU processor models
The CPU processor models used by different specifications of cloud server CVM are specified, and are detailed in the comparison table of cloud server CVM instance specifications . However, when creating a lightweight application server, it is not supported to specify the CPU model of the underlying physical server. Tencent Cloud will randomly allocate a physical CPU model that meets the package specifications.
For example: the standard S5 cloud server CPU uses Intel Xeon Cascade Lake or Intel Xeon Cooper Lake processors, with a main frequency of 2.5GHz and a turbo frequency of 3.1GHz; the computing C6 instance processor uses an Intel Xeon Ice Lake processor, with a main frequency of 3.2GHz. Turbo frequency 3.5GHz. The lightweight application server does not specify the CPU processor model.
3. Differences in public network bandwidth
Tencent Cloud Server CVM public network bandwidth can choose to be billed by fixed bandwidth or traffic usage. Users can choose the public network bandwidth billing mode and bandwidth value at will. The lightweight application server is sold in the form of a package, the package is fixed, the user cannot specify the size of the public network bandwidth, and the public network bandwidth of the lightweight server is limited to monthly traffic.
As shown in the figure above, the CPU memory, public network bandwidth, and system disk of each package of the lightweight server are fixed. Users can only purchase the official package, and cannot customize and modify the package configuration. The public network bandwidth size is fixed for the package. And there is a monthly traffic limit. After exceeding the monthly free traffic package, the traffic fee will be paid at the price of 0.8 yuan per GB for the excess part. Note: The unit price of the traffic fee of 0.8 yuan/GB refers to the mainland China region. The traffic fee price of the lightweight application server is different in different regions. The traffic fee of the lightweight server in Hong Kong, China is 1 yuan/GB. The traffic price reference in different regions: Light The price list for excess traffic beyond the application server package .
4. Differences between system disks
The CVM system disk of Tencent Cloud Server can choose high-performance cloud hard disk, SSD cloud hard disk, enhanced SSD cloud hard disk and ultra-fast SSD cloud hard disk. Different types of hard disks have different performances and different prices. For details, please refer to: Tencent Cloud Server Cloud Hard Disk Performance and Accurate Quotation . All lightweight application servers are equipped with SSD system disks as standard, and users cannot customize cloud disks.
Generally speaking, in some preferential activities of Tencent cloud server, the special price cloud server CVM is configured with high-performance cloud hard disk by default, while the lightweight application server is configured with SSD system disk by default. Compared with the high-performance cloud hard disk of cloud server CVM and the SSD of lightweight server System disk performance is better.
5. Intranet connectivity and cluster application differences
The cloud server CVM is a professional-grade cloud server. CVM instances can be connected with load balancing and cloud database intranets to build high-availability and high-disaster recovery cluster applications. Lightweight application servers are generally used for stand-alone applications that only require one cloud server. The cloud server CVM can create a private network VPC, and plan and maintain the network on the private network by itself, such as specifying a private network IP address, planning an intranet, creating a switch, and other functions. use the server
In terms of intranet connectivity, lightweight application servers are worse than cloud server CVMs. The cloud server CVM has the concept of availability zone, but the lightweight application server cannot freely choose the availability zone.
Differences between mirrored operating systems
The advantage of the lightweight application server is that it provides an application image, through which users can build the required program and the configuration environment that the program depends on with one click.
The application images supported by the lightweight application server include: Pagoda Panel , WordPress, SRS, Room Service, Discuz, Typecho, Cloudreve, LAMP, Node.js, ASP.NET, Theia IDE, Docker, K3s, etc.
Tencent Cloud Encyclopedia takes the WordPress application image as an example. Assuming that the purpose of purchasing a cloud server is to build a WordPress website blog, you can choose a lightweight application server and choose a WordPress image in the application image. Tencent Cloud will install the required WP on the basis of the operating system. Web environments such as PHP, MySQL, and Nginx, and automatically install the WordPress program. Through application mirroring, you can deploy your desired program and the installation and configuration environment on which the program depends on the server in minutes. It is easy to use and saves time and cost. Developers don't need to waste time on building the basic environment. Especially for novices, there is no threshold to build the required programs.
The public image of the cloud server CVM does not support the application image. The official public image provided by Tencent Cloud is a pure version of the operating system. The program and program environment required by the user need to be manually built by the user.
Of course, in the cloud server CVM image market, you can also choose the integrated environment that has been deployed, but the images provided by the cloud market are provided by third parties, not official ones, and many images are charged. Tencent Cloud public image is a free operating system provided by the government.
Cloud server configuration upgrade differences
Tencent Cloud Server CVM supports custom adjustment and configuration functions, and the CPU memory, bandwidth, and system disk can be upgraded or downgraded. The lightweight application server only supports package upgrades, and cannot fine-tune CPU memory, bandwidth, and system disk configurations. It can only be upgraded to a certain package at one time, and cannot be downgraded.
