This topic describes the traffic pricing of Simple Application Server and relevant precautions.


  • Simple Application Server subscription plans provide traffic quotas on a monthly basis. Traffic within the quota of a plan is free of charge. The overage pricing of a plan is based on the traffic that exceeds the quota.
  • You are charged for outbound traffic, whereas inbound traffic is free of charge.
  • Traffic among application servers within a virtual private cloud (VPC) is free of charge. You are charged an extra fee for the public outbound traffic between Simple Appliance Server and another Alibaba Cloud service.
  • For more information about the overage pricing of a plan, see Pricing.
  • You are not separately charged for bandwidth usage. For example, in a plan that offers 1 vCPU, 1 GB memory, 1 Mbit/s bandwidth, and 20 GB disk space, you are not separately charged for the amount of data transferred at a bandwidth of 1 Mbit/s.

Traffic quotas

Simple Application Server subscription plans provide traffic quotas for each calendar month. The traffic quota of an application server cannot be shared with other application servers. In most cases, the traffic quota can meet your requirements for data transmission. The traffic quota of a plan is reset on the first day of each month. After the traffic quota is reset, the remaining quota from the previous month does not roll over.

Note The system sends you notifications when 50%, 80%, or 95% of the traffic quota is used.

Overage pricing

After the traffic quota is exhausted for the current month, the billing method changes to pay-by-traffic, and overage fees are deducted from your account balance.

Notice To prevent service disruptions when your traffic quota is exhausted, make sure that you have sufficient balance in your account.

Overdue payment

If the traffic quota of a plan is exhausted and your account balance is insufficient to pay for overage bills, the payment becomes overdue and your application server becomes unavailable. To resume your application server, settle the unpaid bills.
