Dedicated instances provide high performance and high service level agreement (SLA) guarantees. Compared with other types of instances, dedicated instances are more suitable for production environments. Fees of a dedicated instance consist of the fees charged for the instance specification and the fees charged for the outbound Internet traffic.

A pay-as-you-go instance starts charging fees the moment you create and start the instance. You can release a pay-as-you-go dedicated instance anytime based on your business requirements. Once an instance is released, it stops charging fees.
The minimum billing cycle of pay-as-you-go instances is one hour. Usage durations are rounded up to the next hour.
For more information about instance specifications, see the buy page.

Usage notes
Top-up notifications
The system estimates an amount based on the average amount payable over the previous seven days for API Gateway and checks whether you have sufficient balance for the next seven days. If the account balance is insufficient, the system notifies you by SMS or email.
If you have enabled balance alert, you will receive an SMS or email reminder when the account balance is less than the specified alert threshold.
Overdue payments
If the available balance in your account is less than the bill amount of the previous billing cycle, the payment for API Gateway becomes overdue. You will receive an SMS message or email that reminds you to make a payment to renew the service.
Service suspension
If you have overdue payments, your APIs fail to be called, and you will receive SMS or email reminders to pay your overdue bills. In this process, you can still manage your APIs.
Service recovery
If you top up your account within six months of the service suspension, the service will be automatically re-activated for use. If you do not top up your account within six months, Alibaba Cloud reserves the right to clear all your API configurations.
