Traffic quota refers to the total of request and response traffic. Only traffic between clients and Points of Presence (POPs) is billed. Origin traffic is free of charge.
You can select a subscription duration of 1 Month, 3 Months, 6 Months, or 1 Year.
The validity period of a plan starts on the date when you purchase the plan and lasts for your subscription duration. For example, if you purchase a 3-month plan at 14:32:10 on June 25, 2024, the plan will expire at 00:00:00 on September 26, 2024.
ESA services calculate traffic using the following conversion factors: 1 GB = 1,000 MB, 1 TB = 1,000 GB, and so on.
Traffic quota rules
After you purchase a plan, the traffic quota is provided according to the following rules:
If the subscription does not cover a full calendar month, the traffic quota for that month is based on the proportion of the remaining time.
The calculated traffic quota is rounded up to the nearest integer.
Unused traffic quota cannot be carried over to the next month.
Example
User A purchased a 3-month Pro plan at 13:37:10 on June 26, 2024, and the plan is valid until 00:00:00 on September 27, 2024. The following table describes the traffic quota provided to User A each month in the validity period:
Month | Remaining hours in the month | Total hours in the month | Remaining time ratio | Traffic quota for the month |
June | 11 + 4 × 24 = 107 | 30 × 24 = 720 | 14.86111111% | 75 GB |
July | 31 × 24 = 744 | 31 × 24 = 744 | 100% | 500 GB |
August | 31 × 24 = 744 | 31 × 24 = 744 | 100% | 500 GB |
September | 26 × 24 = 624 | 30 × 24 = 720 | 86.666667% | 433 GB |
Pay-as-you-go billing for excess usage
If your traffic quota for the current month is exhausted, you can continue using ESA services. Traffic that exceeds the quota is billed according to your plan. Traffic bills are generated on an hourly basis. Each plan has its own billing standards.
Plan | Pricing for excess usage |
Pro | USD 0.03/GB |
Premium | USD 0.166/GB |
Billing examples
Example 1
A personal website of Customer B needs to integrate with ESA. Customer B estimates that the website will need about 2 TB of traffic per month and services including WAF protection, custom rules, whitelisting, rate limiting, and managed rules.
Customer B has specific requirements for WAF protection. They also do not wish to purchase additional DDoS mitigation, want to enable smart routing, and require real-time log delivery.
To meet these requirements, we recommend the Premium plan. If the actual usage for the month is 2.7 TB, the monthly cost is as follows:
Item | Usage | Plan content | Description |
Traffic | 2.7 TB | 1.5 TB | 1.5 TB of traffic is provided in the plan. The excess 1,200 GB of traffic is billed on a pay-as-you-go basis. Monthly cost: 249 + 1,200 × 0.166 = USD 448.2. |
WAF requests | 20 million | Unlimited | Included in the plan |
Static requests | 8 million | Unlimited | Included in the plan |
Dynamic requests | 20 million | Unlimited | Included in the plan |
Value-added services | No pay-as-you-go items enabled except for smart routing. Therefore, no additional cost. Note Smart routing is in trial period and free of charge until December, 1, 2024. | ||
The monthly cost for this customer is 249 + 1200 × 0.166 = USD 448.2.
Example 2
A personal website of Customer C contains both dynamic and static content, with some content requiring Layer 4 acceleration. The monthly traffic usage is about 10 TB, with needs for DDoS protection against volumetric attack and business risk prevention for promotion abuse and other threats. The website also needs protection against SQL injection, cross-site scripting (XSS), and WebShell upload.
To meet these requirements, we recommend the Enterprise plan. Feel free to contact us to customize your plan.
