NAT Gateway: Pay-by-specification billing (discontinued)-NAT Gateway(NAT Gateway)-阿里云帮助中心

Subscription and pay-as-you-go for fixed specifications are no longer available for new purchases.

Subscription

Specification fee

The only billable item for a subscription Internet NAT Gateway is the specification fee:

Specification fee = Unit price of the size (/year) × Subscription duration (years)

Subscription Internet NAT Gateway instances come in Small, Medium, and Large sizes. Prices vary by size.

Region	Small price (/year)	Medium price (/year)	Large price (/year)
China (Qingdao), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Ulanqab), China (Hangzhou), China (Shanghai), China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu)	3,672	7,038	13,770
US (Virginia), China (Hong Kong)	4,896	9,180	18,054
Japan (Tokyo)	5,875.2	11,260.8	22,032
Singapore, Indonesia (Jakarta)	5,508	10,710	20,808
Malaysia (Kuala Lumpur)	5,202	10,404	19,890
US (Silicon Valley)	5,202	10,098	19,278
UAE (Dubai)	11,016	21,114	41,310
Germany (Frankfurt)	6,609.6	12,668.4	24,786
UK (London)	6,732	12,552	24,792

The instance size determines maximum connections and connections per second (CPS). Both SNAT and DNAT connections count toward these limits.
For higher bandwidth, convert from subscription to pay-as-you-go.
In production, factors such as packet size, connection type (long-lived or short-lived), and network architecture affect actual performance. Run a stress test before go-live and configure monitoring to ensure stability.

Size	New connection rate (CPS)	Concurrent connections	Throughput (inbound and outbound traffic)	Packet processing rate (PPS)
Small	1,000	10,000	5 Gbps	600,000
Medium	5,000	50,000
Large	10,000	200,000

Conversion to pay-as-you-go

Converting the billing method does not affect the normal use of your NAT gateway. After the conversion, existing SNAT rules, DNAT rules, EIP bindings, and route configurations remain unchanged. Only the billing mode changes.

Log on to the NAT Gateway console.
In the top navigation bar, select the region where you want to create the NAT gateway.
On the Internet NAT Gateway page, find the target NAT Gateway, and in the Actions column, choose Covert to Pay-As-You-Go.

The instance specification determines maximum connections and connections per second (CPS). Both SNAT and DNAT connections count toward these limits.
For higher bandwidth, convert pay-as-you-go (billed by fixed specification) to pay-as-you-go (billed by usage).
In production, factors such as average packet size, connection type (long-lived or short-lived), and network architecture affect actual performance. Run a stress test before go-live and configure monitoring to ensure stability.

Specification	Connections per second (CPS)	Concurrent connections	Throughput	Packets per second (PPS)
Small	1,000	10,000	5 Gbps	600,000
Medium	5,000	50,000
Large	10,000	200,000
