Edge Security Acceleration:Upgrade a plan

Last Updated:Apr 10, 2025

If your current Edge Security Acceleration (ESA) plan does not meet your needs, you can upgrade to a plan with more quotas and features.

Scenarios

Consider a plan upgrade in the following scenarios:

  • Exceeded traffic usage: The monthly traffic of your website often exceeds the plan limit, incurring additional charges for extra traffic usage.

  • Insufficient rule quota: You need to configure more rules such as caching and configuration rules to adapt to diverse scenarios. However, this demand cannot be fulfilled by your current plan.

  • Higher security requirements: Your origin frequently faces DDoS attacks or intrusion attempts, which indicates that the protection level or policies offered by the existing plan are inadequate.

  • Other feature requirements: You want to add subdomains to ESA, or require security analytics or expert services.

In the above cases, choose the plan that best fits your needs.

Upgrade rules

The following diagram shows the plans offered by ESA.

  • Plan upgrade: You can upgrade from a lower-tier plan to a higher-tier one. Plan downgrade is not supported.

  • Pay the price difference: The new plan inherits the remaining validity time of the original one. You only need to pay for the price difference between the two plans for the remaining duration. For more information, see Billing rules for a plan upgrade.

Before you begin

The plan that you want to upgrade is in the In Effect state. An expired plan cannot be upgraded until it has been renewed. For more information about plan status, see View plan information.

Renew or upgrade your plan

  1. Log on to the ESA console, and in the left-side navigation pane, choose Billing Management > Plans.

Billing rules for a plan upgrade

When you upgrade a plan, the upgrade fee is calculated based on the price difference of your new plan and your original one.

Billing formula

Payment = (New plan price - Original plan price) × Remaining validity period of the original plan × Discount for the remaining validity period

  • Payment: The value is accurate to USD 0.01.

  • Plan price: The plan price on the ESA official website or console.

  • Remaining validity period of the original plan: The new plan inherits the remaining validity period of your original plan. The period is calculated in hours and then converted into months based on a 30-day monthly cycle.

  • Discount for the remaining validity period: If you are eligible for a discount for your original plan, you can use the discount for the remaining validity period.

Traffic quota

After the purchase is complete, your plan quotas are automatically upgraded.

The following rules apply to your traffic quota:

  • Traffic is calculated by calendar month.

  • Traffic is measured in gigabytes (GB). The value is rounded up to the nearest integer.

  • Traffic is converted as follows: 1 GB = 1,000 MB, 1 TB = 1,000 GB, and so on.

The traffic quota after upgrade is calculated as followed:

Important

If you have used up the traffic in your original plan, ESA allocates to you the quota difference between the new and original plans.

Calculation rules for the current month after a plan upgrade

Formula:

Traffic quota this month after the upgrade = Remaining traffic quota this month in the original plan + (Monthly traffic quota in the new plan - Monthly traffic quota in the original plan) × Remaining hours this month / Total hours this month

  • Traffic quota this month after the upgrade: The value calculated based on the formula.

  • Remaining traffic quota this month in the original plan: Traffic quota unused = Monthly traffic quota in the original plan × Remaining hours this month/Total hours this month.

  • Monthly traffic quota in the new plan: The monthly traffic quota of your new plan displayed on the ESA official website or console.

  • Monthly traffic quota in the original plan: The monthly traffic quota of your original plan displayed on the ESA official website or console.

  • Remaining hours this month: The hours left in the current month.

  • Total hours this month: The total hours in the current month.

Example

User A subscribed to a 3-month Entrance plan (50 GB/month) at 15:15:49 on March 11, 2024. The plan is valid until 00:00:00 on June 12, 2024. User A then upgraded to a Pro plan (500 GB/month) at 18:25:42 on March 28, 2024.

The following table describes the traffic quota provided to User A each month in the validity period.

Month

Original monthly traffic quota

Monthly traffic quota after the upgrade

March

32 GB

32 GB + 48 GB

April

50 GB

500 GB

May

50 GB

500 GB

June

19 GB

184 GB

Let's break down the calculation:

  • March:

    • Traffic quota this month left in the original plan: 50 GB/month × [(March 31 - March 12) × 24 hours + (24:00:00 - 15:00:00)]/(31 days × 24 hours) = 31.25 GB. The value is then rounded up to 32 GB.

    • Monthly traffic quota in the new plan: 500 GB/month.

    • Monthly traffic quota in the original plan: 50 GB/month.

    • Remaining hours this month: (March 31 - March 28) × 24 hours + (24:00:00 - 18:00:00) = 78 hours.

    • Total hours this month: 31 days × 24 hours = 744 hours.

    • Traffic quota this month after the upgrade: 32 GB + (500 GB/month - 50 GB/month) × 78 hours/744 hours = 79.1774 GB. The value is then rounded up to 80 GB.

    Therefore, the traffic quota for User A in March is 80 GB.

  • April: The monthly traffic quota of the Pro plan, which is 500 GB.

  • May: The monthly traffic quota of the Pro plan, which is 500 GB.

  • June:

    • Monthly traffic quota in the new plan: 500 GB/month.

    • Remaining validity period this month: (June 12 - June 1) × 24 hours = 264 hours.

    • Total hours this month: 30 days × 24 hours = 720 hours.

    • Available traffic quota this month: 500 GB/month × 264 hours/720 hours = 183.3333 GB. The value is then rounded up to 184 GB.

      Therefore, the traffic quota for User A in June is 184 GB.

Other benefits

After the upgrade completes, you can seamlessly use the features and functionalities offered by the new plan.
