What is the difference between Tencent Cloud lightweight application server and CVM cloud server S5? Which one has better performance? The CVM S5 cloud server CPU uses 2.5GHz Intel® Xeon® Cascade Lake or Intel® If so, the performance of CVM S5 cloud server will be better. Cloud Server Bar will compare the performance differences between Tencent Cloud lightweight application server and CVM server S5 in detail:
Comparison of the differences between Tencent Cloud Lightweight and CVM Cloud Server S5
S5 cloud server belongs to cloud server CVM . The difference between lightweight and S5 is essentially the difference between lightweight application server and cloud server CVM. Lightweight server is a lightweight cloud server, suitable for small and medium-sized enterprises or individual developers. Build lightweight usage scenarios such as corporate official websites, personal blogs, and test environments; cloud server CVM is a professional-level cloud server. CVM is suitable for application scenarios with complex architectures, such as high-concurrency websites, large-scale games, complex distributed cluster applications, and video decoding. , big data and deep learning, etc.
Tencent Cloud Encyclopedia explains in detail the differences between Tencent Cloud Server CVM standard S5 instances and lightweight application servers in terms of cost, CPU processor, public network bandwidth, billing model, cluster application, intranet connectivity, upgrade and downgrade, etc. Performance comparison:
1. Cost price comparison
Compared with cloud server CVM, lightweight application servers are more cost-effective, and lightweight server memory has higher public network bandwidth. Taking the 4-core 8G server as an example, the lightweight 4-core 8G12M comes with 12M public network bandwidth, and the peak download speed of 12M bandwidth can Up to 1536KB/second, 764 yuan per year for 15 months, accurate quotation: Click here to find out. If it is the price of 12M public network bandwidth of CVM S5 cloud server, 12M bandwidth alone costs 745 yuan per month, as shown below:
However, if the public network bandwidth is billed as a fixed bandwidth, the cloud server CVM does not limit the monthly traffic. The Tencent Cloud system will allocate as many M of exclusive bandwidth value as you purchase. However, although the lightweight application server has a relatively high bandwidth value, it has Monthly traffic limit, for example, discounted 4-core 8G12M will limit free monthly traffic to 2000GB. Traffic exceeding the free limit requires additional traffic fees, but for general use, the built-in traffic package is enough. Therefore, if you pursue cost-effectiveness, give priority to lightweight application servers, which have higher CPU and memory bandwidth configurations and lower costs.
2. CPU frequency processor model description
The CPU of the standard S5 instance of Tencent Cloud CVM server uses 2.5GHz Intel® Xeon® Cascade Lake or Intel® Allocate physical CPU models that meet package specifications, usually giving priority to newer generation CPU models. As shown below:
3. CPU memory performance comparison
Is the performance of lightweight application servers poor? No, compared with the standard cloud server CVM of the same specification, the CPU and memory performance of the lightweight application server are at the same level. A Xiaoyun takes the 2-core 4G configuration as an example. The CPU memory performance of the lightweight 2-core 4G5M server and the 2-core 4G standard S5 instance (S5.MEDIUM4) are at the same level. As shown below:
4. Comparison of public network bandwidth and monthly traffic
If the CVM bandwidth of Tencent Cloud Server is billed according to fixed bandwidth, the bandwidth is exclusive. Tencent Cloud will allocate as many M of exclusive bandwidth as you buy. There is no traffic limit. You can use it as you like. Even if it is full every day, it will be fine. Tencent The cloud will not charge additional traffic fees. The lightweight application server has a monthly traffic package limit. Ateng Cloud takes the 8-core 16G18M lightweight server as an example. It comes with a 3500GB monthly traffic package. The traffic in the monthly traffic package is free, and the traffic requirements exceed the monthly traffic package. In addition, pay a traffic fee, which is generally 0.8 yuan/GB. The actual traffic unit price also varies in different regions. For details, please refer to: https://cloud.tencent.com/document/product/1207/73452
Many students will become anxious about traffic when they see that the lightweight application server has a monthly traffic package limit. In fact, not all traffic will be billed. Tencent Cloud only charges the traffic generated by the lightweight application server in the public network outbound direction. Both inbound and intranet traffic are free, as shown below:
5. 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.
How to choose between lightweight server and S5 cloud server?
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.
