Does Tencent Cloud Virtual Machine have traffic restrictions? Tencent Cloud Virtual Machine generally do not limit traffic, but may limit bandwidth. In fact, any service provider that does not limit space or traffic, etc., in fact, there will be restrictions, but through different means to achieve.

When the number of visits to the website suddenly increases, we can adopt some methods to solve the problem of large traffic to the server and avoid affecting user access due to restrictions.

1. Upgrade server hardware

That is to expand the Cloud Virtual Machine. Ordinary P4 servers can generally support up to 100,000 independent IPs per day. If the access volume is larger than this, then a dedicated server with higher performance must be configured first to solve the problem. Otherwise, no optimization can completely solve the performance problem.

2. Optimize database access

Cloud Virtual Machine load is too large, an important reason is the CPU load is too large, reduce the CPU load, can effectively break the bottleneck. Using static pages minimizes CPU load. Of course, it is best to achieve complete statics in the foreground, and you can completely avoid accessing the database, but for frequently updated websites, statics often cannot meet certain functions.

Caching technology is another solution, storing dynamic data in cached files that dynamic web pages call up directly without having to access the database. If you really can't avoid accessing the database, you can try to optimize the query SQL of the database. Avoid using statements like Select * from. Each query only returns the results you need. Avoid a large number of SQL queries in a short time.

3. Control large file downloads

Downloading large files takes up a lot of traffic, and for non-SCSI hard disks, large file downloads consume cloud host CPU, making the website less responsive. Therefore, try not to provide more than 2M large file downloads, if you need to provide, it is recommended to put large files on another server.

4. Use traffic analysis statistical software

Install a traffic analysis software on your website to know in time which places are consuming a lot of traffic and which pages need to be optimized. Solving the traffic problem also requires accurate statistical analysis.

Cloud Virtual Machine can freely select CPU, memory, data disk, bandwidth and other configurations. It can also upgrade bandwidth at any time without downtime, and upgrade CPU and memory within 1 minute, so as to support the continuous development of business.
