What is the difference between Tencent Cloud lightweight server and cloud server? Why are lightweight application servers so cheap? Is it because the lightweight server CPU memory performance is worse than the cloud server CVM performance? The lightweight application server is suitable for small and medium-sized enterprises or individual developers to build corporate official websites, blog forums, WeChat applets or development and testing environments. The cloud server CVM is suitable for more complex application scenarios such as highly concurrent websites, big data computing, machine learning and other complex application scenarios. The difference between Tencent Cloud lightweight application server and cloud server CVM will be explained in detail in terms of performance testing, network bandwidth, billing price, application construction and user suitability:
The difference between Tencent Cloud lightweight application server and cloud server
Tencent Cloud lightweight application server is a new generation of cloud server that is fast to build, easy to manage, and cost-effective based on the cloud server CVM. Users like some small and medium-sized enterprises or individual developers do not need to choose a cloud server for simple application architecture. . The biggest advantage of cloud servers over lightweight application servers is that cloud servers can build high-availability and high-disaster-tolerant cluster applications with instances such as load balancing and cloud databases. However, not all application scenarios require professional-level cloud server CVM. As a basis, for most website web application scenarios, WeChat applet servers, cloud disks, APP client development, e-commerce applications, cloud disk image beds and other lightweight application scenarios, a lightweight application server is enough. The focus is on price. And discount.
In addition, lightweight application servers are a trend, and major cloud vendors are flocking to them. Not only Tencent Cloud, Alibaba Cloud was the first to launch lightweight application servers. Huawei Cloud's Yunyao Cloud Server HECS is also a similar lightweight cloud server. Baidu Intelligent Cloud's lightweight application server is in public beta.
1: Performance differences between lightweight application servers and cloud servers
Why are lightweight application servers so cheap? Is the performance of lightweight servers worse than cloud servers? No, compared with the standard cloud server CVM of the same specifications, the CPU and memory performance of the Tencent Cloud lightweight application server are at the same level as the standard cloud server CVM .
Note: The unified performance level is compared with standard cloud server CVM instances. If compared with high IO, heterogeneous GPU, and computing cloud server CVM instances, the performance is still different.
2: Comparison of main frequency differences between CPU models
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. CVM instances of different specifications of cloud servers have specified CPU models and clock speeds (refer to: Description of CPU processor models of different specifications of cloud server CVM ).
There are currently 2 lightweight application servers under the Tencent Cloud account of the lightweight server network. Check the CPU processor model and frequency.
The lightweight application server tested in this article is Tencent Cloud's 1-core 1G30M bandwidth Hong Kong lightweight server. The CPU model used is Intel(R) Xeon(R) CPU E5-26xx v4, clocked at 2.4G Hz. The popular lightweight server with 2 cores and 4G6M bandwidth is currently popular at events. The CPU processor generally uses Intel(R) Xeon(R) Gold 6133 CPU with a main frequency of 2.5GHz and a turbo frequency of 3.0GHz.
Three: Comparison of public network bandwidth
Tencent Cloud lightweight application server is sold in the form of packages, and the cloud server CVM can customize the public network bandwidth size. Lightweight Server Network believes that the public network bandwidth of cloud server CVM is better than that of lightweight servers. The bandwidth of lightweight application servers is the peak bandwidth. The peak bandwidth refers to the highest bandwidth value that can be achieved theoretically. In practice, it may not be reached at ordinary times, and it is lightweight. The bandwidth of the mass server has a monthly traffic package limit ; the public network bandwidth of the cloud server CVM is exclusive, and the bandwidth purchased will be exclusive to you. The public network bandwidth of the lightweight application server is limited by the monthly traffic package.
The lightweight application server is purchased according to the package. The CPU memory, bandwidth and system disk package officially provided by Tencent Cloud cannot be customized and purchased. It can only be purchased according to the package. And the public network bandwidth has a monthly traffic package limit. If it exceeds You need to pay additional traffic fees for the monthly traffic package in the package, and the price per GB of traffic is approximately 0.8 yuan. Reference: Tencent Cloud lightweight application server configuration quotation and traffic package excess fee .
Four: Monthly traffic comparison
The public network bandwidth of cloud server CVM does not limit monthly traffic. Lightweight applications are sold according to packages. Each lightweight application server has a monthly traffic limit. Tencent Cloud Encyclopedia takes a lightweight 2-core 4G5M configuration as an example, 168 times a year. Yuan, 198 Yuan for 15 months, 628 Yuan for three years, 500GB monthly traffic, the traffic generated in the monthly package is free, excess traffic requires an additional traffic fee, the price is 0.8 yuan per GB. The traffic prices of lightweight servers in different regions are also different. The traffic prices of lightweight servers in different regions are as follows:
| region | Price (yuan/GB) |
|---|---|
| Mainland China, Singapore, Tokyo, Frankfurt, Seoul | 0.8 |
| China Hong Kong | 1.0 |
| mumbai | 0.58 |
| silicon valley | 0.5 |
But don’t worry, generally speaking, the monthly traffic that comes with a lightweight server is enough. For example, for a lightweight server under a cloud server account, the monthly traffic is not only unused, but also leftover. Of course, if it is a video application, it is definitely not enough.
It should be noted that the billable traffic of the lightweight application server refers to the public network outbound traffic. Both private network traffic and public network inbound traffic are free, so you don’t have to worry about traffic. Lightweight server traffic charges and free instructions .
Five: Comparison of price differences between lightweight servers and CVM cloud servers
Tencent Cloud lightweight application server has high configuration and low price. The public network bandwidth starts at 4M. The quotation table is out: click to learn more. The lightweight application server also has greater discounts.
Please refer to the official page for the preferential price of Tencent Cloud Server CVM . Under the same CPU and memory configuration, the price of Cloud Server CVM is more expensive.
Six: Differences in billing models
Ateng Cloud has already said before that lightweight application servers are sold according to packages. The CPU, memory, bandwidth and system disk configurations are fixed, and only support the annual and monthly billing model. Users can choose the corresponding package according to actual needs. The cloud server CVM supports a variety of billing models, such as pay-as-you-go, annual and monthly subscriptions, and bidding instances.
Users can freely choose cloud server CVM instance specifications, CPU memory, bandwidth, system disk and other configurations. Reference: https://cloud.tencent.com/document/product/213/2180
Seven: Differences in system disks
All lightweight application servers are equipped with SSD cloud disks as standard, while cloud server CVM system disks or data disks can be selected as high-performance cloud disks, general-purpose SSD cloud disks or SSD cloud disks. In terms of hard disk storage, lightweight application servers have more advantages. It should also be noted that the cloud disk of the lightweight application server and the cloud disk of the cloud server are independent of each other and do not support mounting each other.
8: Differences between cluster applications and intranet connectivity
The intranet connectivity of lightweight application servers is worse than that of cloud servers. Cloud servers can connect to load balancing instances, cloud database instances, and intranets to build high-availability cluster applications. Lightweight application servers are generally used for stand-alone applications that only require one cloud server. The cloud server can create a private network VPC, and plan and maintain the network on its own on the private network, such as specifying private IP addresses, planning intranets, creating switches, and other functions.
Lightweight servers do not support secondary virtualization or installation of virtualization software. Blackstone physical servers support secondary virtualization. Tencent Cloud lightweight application servers have the concept of availability zones, while Alibaba Cloud lightweight servers currently do not have availability zones to choose from. In terms of intranet connectivity, lightweight application servers are worse than cloud servers CVM. Cloud server CVM has the concept of availability zones, while lightweight application servers cannot freely select availability zones. And after the lightweight application server instance is created, changing the intranet IP address is not supported. In the past, the lightweight server did not support changing the public IP address, but now it supports changing the public IP address. Lite does not support user-defined configuration of private network VPC, and the network is automatically created and allocated by the system.
9: Differences in cloud server system images
The lightweight application server provides application image templates. Users can use the application image to build the required program and the configuration environment that the program depends on with one click.
The lightweight application server has a lower threshold for use and provides application images. Using application images, you can install the required programs and operating environment 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. Cloud server CVM images support public images, custom images, shared images and the image market.
Application mirroring is very convenient. Take WordPress as an example. Select WordPress for the mirror. After the cloud server is created, the WordPress blog website can be online. There is no need for users to build the Web environment required for WordPress, and there is no need to manually install the WordPress program. Use the application mirror website Online in minutes.
10: Cloud server CVM and lightweight application server are suitable for people and application scenarios
Lightweight application servers are suitable for small and medium-sized enterprises and individual developers; while cloud server CVM is for all cloud users. The threshold for using cloud servers is higher and is more suitable for applications such as individuals and enterprises with certain open capabilities. Cloud servers are suitable for application scenarios with complex architectures, such as highly concurrent websites, large-scale games, complex distributed cluster applications, video encoding and decoding, big data analysis, machine learning, deep learning, etc.; while lightweight application servers are more suitable for simpler stand-alone applications. , such as corporate websites, blogs, product display websites, WeChat applets, general Web application scenarios, mobile APPs, applets, cloud disks, image beds, cloud development and testing environments and learning environments, etc.
