  3. Specify required parameters for the FlexusL instance.

    Parameter

    Example

    Description

    Region

    CN-Hong Kong

    For low network latency and quick resource access, select the region nearest to your target users. After a FlexusL instance is created, the region cannot be changed. Exercise caution when selecting a region.

    Application Images

    Select the Portainer application image.

    Instance Specifications

    • Host security
    • Cloud backup vault: 90 GiB

    You can bundle any of the services to your FlexusL instances as needed: EVS, HSS (basic edition), and CBR and set specifications as needed.

    Required Duration

    1 month

    The minimum duration of a purchase is one month and the maximum duration is three years.

    Auto-renew is enabled by default, which means the purchased FlexusL instances will be automatically renewed before they expire. If you do not enable auto-renew during the purchase process, you can still enable it later after the instances are created. Monthly subscription allows you to renew the subscription for one month every time. The number of renewal times is not limited.
