Billing details

ENS instances can access the internet through a static public IP address of a network interface card, an Elastic IP Address (EIP), or an edge NAT Gateway. The bandwidth generated by each access method is measured and billed separately.

Note

The Edge NAT Gateway feature is currently free of charge. Affected customers will be notified one month before billing starts.

Billing for static public IP bandwidth

When you create an ENS instance, you can choose to assign a public IP address to its network interface card. The system then automatically assigns a static public IP address to the instance for internet access. If you use a static public IP address, you are charged only for public bandwidth.

Note

In pay-as-you-go mode, the peak inbound and outbound bandwidth values are upper limits and not guaranteed service commitments. The peak bandwidth may be limited when resource contention occurs.

Outbound bandwidth refers to the public bandwidth traffic that flows out of an ENS instance. Inbound bandwidth refers to the public bandwidth traffic that flows into an ENS instance. ENS measures the inbound and outbound bandwidth of all instances on each edge node every 5 minutes. The higher of the two values is used as a valid peak bandwidth data point.

The daily peak bandwidth, monthly 4th peak bandwidth, and monthly 95th percentile bandwidth billing methods are supported. For more information about the billing rules, see Public bandwidth billing rules.

Billing for EIP bandwidth

If an ENS instance is attached to an EIP, the instance can access the internet through the EIP. You are charged for the EIP configuration and the public bandwidth that the EIP uses.

Note

Currently, EIPs under the same Alibaba Cloud account can use different billing methods. For example, if you purchase three EIPs, you can use the pay-by-traffic billing method for the first EIP and the monthly 95th percentile billing method for the other two. For billing purposes, ENS merges the bandwidth of EIPs that are under the same account, on the same edge node, and use the same billing method.

The inbound and outbound bandwidth of all EIPs on an edge node is measured. The higher of the two values is used as a valid peak bandwidth data point.

Starting from 00:00 on April 1, 2024, configuration fees apply to EIPs. The billing rules are as follows:

Category	Description
Billing method	Pay-as-you-go.
Billing cycle	Bills are generated on a calendar month basis.
Unit price	USD 14.3/month/instance.
Billing rules	The final fee is the sum of the configuration fees for all EIP instances in the current month. Configuration fee for an EIP instance = Unit price × Validity factor. Note Validity factor = Number of valid days / Total days in the month. For example, if June 2024 has 30 days and the number of valid days in the bill is 17, the validity factor is 17/30 = 0.56666667. Number of valid days: The number of days from when an EIP instance is created to when it is released within a calendar month. If the instance is not released in the current month, the period ends on the last day of the month. For example: Scenario 1: An instance is created on June 5, 2024, and released on June 25, 2024. The number of valid days in June 2024 is 21. Scenario 2: An instance is created on June 5, 2024, and is used until the end of the month. The number of valid days in June 2024 is 26.

Public bandwidth billing rules

A single billing cycle and billing method are used for all static public IP bandwidth under the same Alibaba Cloud account. This billing cycle also applies to other pay-as-you-go resources, such as instances and disks, under the same account. For example, if you select the monthly 95th percentile bandwidth billing method when you create your first instance, all existing and new static public IPs under your account are billed using the monthly 95th percentile method. Consequently, the monthly billing cycle also applies to all existing and new pay-as-you-go instances and disks under your account. For more information about billing methods, see Pay-as-you-go (user-level, deprecated).

Daily peak bandwidth

Item	Description
Billing rules	The daily peak bandwidth is billed on a daily basis. The inbound and outbound bandwidth of all instances on each edge node is measured every 5 minutes. The higher of the two values is used as a valid peak bandwidth data point. This process generates 288 data points per day. The highest value among them is taken as the daily peak bandwidth for the node.
Billing method	Pay-as-you-go.
Billing cycle	Bills are generated on a daily basis. After 00:00 each day, a bill for the previous day is generated and the fee is deducted. The actual billing time is subject to the system.
Formula	The final fee is the sum of the bandwidth fees for all nodes on that day. Bandwidth fee for a single node on a given day = Daily peak bandwidth × Unit price of daily peak bandwidth.

Monthly 4th peak bandwidth

Category	Description
Billing rules	The monthly 4th peak bandwidth is billed on a calendar month basis. Within a calendar month, the daily peak bandwidth is calculated. The inbound and outbound bandwidth of all instances on each edge node is measured every 5 minutes, and the higher value is used as a valid peak bandwidth data point. All daily peak bandwidth values are sorted in descending order. The fourth highest value is used as the billable bandwidth. If no bandwidth is used during certain periods, no data points are generated for those periods.
Billing method	Pay-as-you-go.
Billing cycle	Bills are generated on a calendar month basis. On the first day of the next calendar month, a bill for the previous month is generated and the fee is deducted. The actual billing time is subject to the system.
Formula	The final fee is the sum of the bandwidth fees for all nodes in that month. Bandwidth fee for a single node in a given month = Fourth highest daily peak bandwidth of the month × Unit price of monthly 4th peak bandwidth × Validity factor Note Validity factor: Validity factor = Number of valid days in the month / Total days in the month. For example, if June 2024 has 30 days and the number of valid days in the billing cycle is 17, the validity factor is 17/30 = 0.56666667. Number of valid days: The number of days in which public bandwidth was used. For example, if public bandwidth usage starts on June 5, 2024, and continues until June 21, 2024, with no further usage in the month, the number of valid days for June 2024 is 17.

Monthly 95th percentile bandwidth

Category	Description
Billing rules	The monthly 95th percentile bandwidth is billed on a calendar month basis. Within a calendar month, the inbound and outbound bandwidth of all instances on each edge node is measured every 5 minutes. The higher of the two values is used as a valid peak bandwidth data point. All data points (N) are sorted in descending order. The top M data points are discarded, where M is calculated as N × 0.05 and rounded down to the nearest integer. The (M+1)th data point is the 95th percentile billable bandwidth for the month. If no bandwidth is used during certain periods, no data points are generated for those periods.
Billing method	Pay-as-you-go.
Billing cycle	Bills are generated on a calendar month basis. On the first day of the next calendar month, a bill for the previous month is generated and the fee is deducted. The actual billing time is subject to the system.
Formula	The final fee is the sum of the bandwidth fees for all nodes in that month. Bandwidth fee for a single node in a given month = 95th percentile billable bandwidth of the month × Unit price of monthly 95th percentile bandwidth × Validity factor Note Validity factor: Validity factor = Number of valid days in the month / Total days in the month. For example, if June 2024 has 30 days and the number of valid days in the billing cycle is 17, the validity factor is 17/30 = 0.56666667. Number of valid days: The number of days in which public bandwidth was used. For example, if public bandwidth usage starts on June 5, 2024, and continues until June 21, 2024, with no further usage in the month, the number of valid days for June 2024 is 17.
