Tencent Cloud 4-core 8G server lightweight and CVM
1. Tencent Cloud 4-core 8G server lightweight and CVM costs
In the Tencent Cloud official event: https://curl.qcloud.com/HmjGZiLu , 4-core 8G configuration can be selected as a lightweight application server or cloud server CVM standard S5 instance. The lightweight comes with 12M public network bandwidth and CVM S5 bandwidth. 1M, 3M, 5M and 10M are optional. The detailed configuration is as follows:
| Cloud Server | CPU memory | Public network bandwidth | system disk | Monthly traffic package | Regional node | Tencent Cloud Server Network |
|---|---|---|---|---|---|---|
| Lightweight application server (universal type-4 core 8G-180G-2000G) | 4 core 8G | 12M | 180GB SSD disk | 2000GB monthly traffic | Shanghai, Guangzhou, Beijing | 446 yuan for one year, 518 yuan for 15 months |
| Cloud server CVM (S5.LARGE8 4h8g.com) | 4 core 8G | 1M、3M、5M、10M | 180GB SSD disk | Unlimited traffic | Guangzhou/Shanghai/Beijing | Starting from 935 yuan per year |
As shown in the table above, the Tencent Cloud Server CVM standard S5 instance 4-core 8G configuration with 1M bandwidth is 935 yuan per year, the 3M bandwidth configuration is 1,049 yuan per year, the 5M bandwidth configuration is 1,176 yuan per year, and the 10M configuration is 2,317 yuan per year. The lightweight application server's 4-core 8G12M configuration comes with 12M public network bandwidth. The 4-core 8G12M lightweight configuration is 446 yuan for one year and 518 yuan for 15 months, so the lightweight application server is more cost-effective .
It is recommended to choose the lightweight application server Lighthouse for lightweight businesses such as small programs and website building. The cloud server CVM is preferred for scenarios with stable business volume, such as highly concurrent websites, large games, complex distributed cluster applications, video codecs, and big data. For usage scenarios such as analysis, machine learning, and deep learning, you must choose cloud server CVM.
2. CPU frequency processor model
Is there any difference between Tencent Cloud lightweight server and cloud server CVM processor? What CPUs are used? What is the main frequency? The cloud server CVM S5 cloud server CPU uses a 2.5GHz Intel® Xeon® Cascade Lake or Intel® Xeon® Cooper Lake processor. Lightweight does not support specifying the CPU. When creating a lightweight application server, it does not support specifying the CPU model of the underlying physical server. Tencent Cloud will randomly allocate physical CPU models that meet the package specifications, and usually give priority to newer generation CPU models. As shown below:
The lightweight application server does not support random allocation of processors for specified CPU models.
3. CPU memory computing performance comparison
Which one has better performance, lightweight or CVM S5? The cost of lightweight application servers is lower. Is it because the CPU performance of lightweight servers is not good? Compared with the standard cloud server CVM of the same specifications, the CPU and memory performance of the lightweight application server are at the same level. As shown below:
The CPU and memory performance of the lightweight server are at the same level as the standard CVM.
CPU memory performance, lightweight and CVM S5 cloud server performance are similar. If compared in terms of functions, intranet connectivity, cluster and public network bandwidth, the CVM S5 cloud server performance will be better.
Cloud server CVM S5 instances belong to cloud server CVM. The difference between S5 server and lightweight server in this article is actually the difference between lightweight application server and cloud server CVM.

4. Public network bandwidth description
Tencent Cloud's lightweight 4-core 8G12M server comes with 12M public network bandwidth, and the peak download speed of 12M bandwidth can reach 1536KB/s, equivalent to 1.5M/s; cloud server CVM can choose 1M, 3M, 5M and 10M in the official special offer . The CVM cloud server S5 instance 4-core 8G10M bandwidth is 2317 yuan per year. It seems that the CVM cloud server bandwidth will be more expensive, but this is already after the event. If you purchase the bandwidth separately, it will be more expensive. The cloud server uses CVM 12M bandwidth For example, let me show you the inactive bandwidth, as shown below:
Tencent Cloud Server CVM public network bandwidth 12M
As shown in the picture above, the 12M bandwidth of Tencent Cloud CVM cloud server is 745 yuan per month, so although the cloud server CVM at the event looks more expensive than the lightweight application server, it is already very cheap, and you can also get coupons: https: // curl.qcloud.com/HmjGZiLu Cloud server-specific discount coupons.
Cloud server CVM is an exclusive public network bandwidth. The peak bandwidth of a lightweight application server may not be as good as that of a cloud server CVM. The key point is that if a cloud server CVM is billed according to a fixed bandwidth, there is no traffic limit. Even if it is full every day, there is no need to pay for additional traffic. There is a fee, but the 4-core 8G12M lightweight server has a monthly traffic limit of 2000GB. Speaking of traffic, Ateng Cloud will explain in detail:
5. Description of traffic restrictions
It seems that the public network bandwidth of the lightweight application server is relatively high, but there is a monthly traffic limit. The 4-core 8G12M limit is 2000GB monthly traffic. However, the system will allocate how many M of exclusive bandwidth the cloud server CVM buys. , and CVM is billed based on fixed bandwidth and does not limit traffic. You can use it as you like. Even if it is full every day, you do not need to pay additional traffic fees.
It should be noted that not all traffic generated by the lightweight server is charged. Only the traffic generated by the lightweight server in the public network outbound direction is charged. Traffic in the intranet and public network inbound direction is not charged, as shown below:
Tencent Cloud lightweight application server free traffic and paid traffic
You don’t need to be too anxious about the traffic limit of lightweight application servers. For general applications, the traffic package that comes with lightweight servers is enough, and there may even be some leftover. Of course, if it is a video application, the traffic will definitely not be enough.
So the question is, what should I do if the traffic of the lightweight application server exceeds the quota for the month? The excess traffic requires additional traffic fees. If it is in mainland China such as Beijing, Shanghai, and Guangzhou, the traffic is 0.8 yuan per GB. For information on lightweight traffic fees, please refer to: How is Tencent Cloud lightweight application server traffic charged ?
6. Differences between cluster applications and intranet connectivity
If it is a cluster application, you must choose cloud server CVM. 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 clusters. application. 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.
In summary, it is a 4-core 8G Tencent cloud server. The lightweight 4-core 8G12M server is suitable for small and medium-sized enterprises and individual developers. It is more cost-effective and lightweight and can be used to build corporate websites, blogs, product display websites, WeChat applets, General web application scenarios, mobile APPs, small programs, cloud disks, image beds, cloud development and testing environments and learning environments, etc.; the 4-core 8G cloud server CVM is open to all cloud users, and the cloud server usage threshold is higher and more suitable for Applications for individuals and enterprises with certain open capabilities. Cloud server CVM is 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 and other usage scenarios.
