How to choose appropriate server bandwidth based on website traffic?

To choose appropriate server bandwidth based on website traffic, you need to analyze your website's expected traffic volume, data transfer requirements, and performance goals. Here’s a step-by-step guide:

1. Estimate Daily Visitors and Page Views:
   Calculate the average number of daily visitors and page views. For example, if your site has 10,000 daily visitors and each visitor views 3 pages, you’ll have 30,000 page views per day.

2. Calculate Data Transfer per Page:
   Determine the average size of a page (including images, scripts, etc.). For instance, if each page is 2 MB, the daily data transfer would be:
   30,000 page views × 2 MB = 60,000 MB (or ~60 GB/day).

3. Factor in Peak Traffic:
   Account for traffic spikes (e.g., during promotions or news events). If peak traffic is 3x your average, adjust bandwidth accordingly.

4. Add Buffer for Growth:
   Reserve extra bandwidth (e.g., 20-30%) to accommodate future growth or unexpected surges.

5. Choose Bandwidth Tier:

   • Low Traffic (1-10 GB/month): Shared hosting or basic VPS with 1-5 Mbps bandwidth.
   • Medium Traffic (10-100 GB/month): VPS or cloud server with 5-20 Mbps bandwidth.
   • High Traffic (100+ GB/month): Dedicated server or scalable cloud solution with 50+ Mbps bandwidth.

Example:
A news website with 50,000 daily visitors, 5 MB pages, and peak traffic 2x normal would need:
50,000 × 5 MB × 2 = 500,000 MB (~500 GB/day).
This requires at least 1 Gbps bandwidth for smooth performance.

For scalable solutions, Tencent Cloud offers Elastic IP and Bandwidth Packages, allowing you to adjust bandwidth dynamically based on traffic. Their LightHouse and CVM services also provide cost-effective options for varying workloads.
