    API Gateway:Upgrade or downgrade the specification of a Cloud-native API Gateway instance

    Last Updated:Feb 20, 2025

    This topic describes how to upgrade or downgrade a Cloud-native API Gateway instance.

    Prerequisites

    A Cloud-native API Gateway instance is created. For more information, see Create a gateway instance.

    Background information

    You can upgrade or downgrade the specifications of Cloud-native API Gateway instances that use the subscription or pay-as-you-go billing method. For more information about the billing of upgraded or downgraded instance specifications, see Billing overview.

    Procedure

    Important

    • The time required to complete the upgrade or downgrade is approximately 4 to 5 minutes. During this period, you cannot perform operations on the instance in the console.

    • For an instance that contains two or more nodes, a rolling deployment is performed for the nodes and data is automatically synchronized on these nodes. Your business is not affected in this process. Instances that contain only one node cannot provide high availability, and service interruptions may occur when you upgrade or downgrade the instance specifications.

    • To ensure the continuity of your business, we recommend that you perform the upgrade or downgrade during off-peak hours.

    1. Log on to the Cloud-native API Gateway console.

    2. In the left-side navigation pane, click Instance. In the top navigation bar, select a region.

    3. On the Instance page, select the instance that you want to manage.
