Manage VPC quotas - Virtual Private Cloud - Alibaba Cloud Documentation Center

Alibaba Cloud allows you to view and manage quotas of your Alibaba Cloud services. You can obtain usage information, apply for increases on quotas, and create alert rules for quotas. This topic describes the prerequisites and procedures for managing virtual private cloud (VPC) quotas.

Background information

Quota Center allows you to manage the quotas of various Alibaba Cloud services in a centralized manner. VPC and many other Alibaba Cloud services work with Quota Center. If you are using multiple Alibaba Cloud services and want to manage the quotas of all your cloud services in one console, you can use Quota Center.

Alternatively, you can individually manage VPC quotas by using the quota management feature provided in the VPC console.

Limits

By default, only the Alibaba Cloud account is authorized to manage quotas in Quota Center. If you want to allow RAM users to manage quotas, you must first grant the RAM users the AliyunQuotasFullAccess permission. For more information, see Authorize a RAM user.

View quotas

You can view the quotas of VPC by using one of the following methods:

To view the quota items and their default values, see Quotas.
Log on to the Quota Center console to view quotas. For more information, see Query the details of quotas supported by a cloud service.

Procedure (VPC console)

Log on to the VPC console.
In the left-side navigation pane, choose O&M and Monitoring > Quota Management.
On the Quota Management page, click the VPC tab in the Service section. In the Quota Type section, select the type of quota that you want to view.

Most of the quotas provided are adjustable. If the default quota is unable to meet your business requirements, you can apply for a quota increase by using one of the following methods:

Use the Quota Center console. For more information, see Request a quota increase.
Use the VPC console.

If the application is successful, the increased quota limit will be displayed in the Quota Center console and the service console.

Procedure (VPC console)

Log on to the VPC console.
In the left-side navigation pane, choose O&M and Monitoring > Quota Management.
On the Quota Management page, click the VPC tab in the Service section. In the Quota Type section, select the type of quota that you want to adjust.
- Adjust general quotas.

    Note
    Applications are approved by the technical support team of the corresponding cloud service. When you apply for a quota increase, specify a reasonable quota value and provide as much information as possible. The more justification provided, the more likely your application will be approved.
    Application results are sent to you by text message and email.
    Alibaba Cloud reviews your application based on the information provided in the application.
  4. To view the status of the application, click Application Records or choose > Application Records in the Actions column.
    If the application is in the Approved state, the quota is increased.

  3. In the Apply for Privileges dialog box, specify the Quota Value, Time, Reason, and Notify Result parameters. Then, click OK.
    Note
    If you do not specify a start time for the validity period, the default start time is the time when the quota increase application is submitted. If you do not specify an end time for the validity period, the default end time is 99 years after the start time. The end time must be later than the start time.
    Applications are reviewed and approved by the technical support team for each cloud service. To increase the success rate of your application, you must specify a reasonable quota value and a detailed reason when you submit an application.
    Application results are sent to you by using text messages and emails.
  4. To view the status of the application, click Application Records in the Actions column. If the application is in the Approved state, the privilege is acquired.

Create an alert rule for a quota item

You can create alert rules for some quota items by specifying a threshold for quota usage or available quota. If the usage of a quota reaches the specified threshold, the system sends an alert notification to the callback URL that you specified in the alert rule through an HTTP POST request. We recommend that you take the alerts into consideration and apply for a quota increase in advance to avoid unexpected business interruptions.

You can create alert rules by using one of the following methods:

Use the Quota Center console. For more information, see Create an alert rule for a quota item.
Use the VPC console.

You can create alert rules for the following quota items:

Name: vpc_quota_secondary_cidr_num. Description: Maximum number of secondary IPv4 CIDR blocks supported by each VPC.
Name: vpc_privilege_allow_buy_havip_instance. Description: The privilege to purchase HAVIPs.

Procedure (VPC console)

Log on to the VPC console.
In the left-side navigation pane, choose O&M and Monitoring > Quota Management.
On the Quota Management page, choose VPC > General Quota. Find the quota that you want to manage and click Create Alert Rule in the Actions column.

In the Create Quota Alert Rule panel, configure the parameters and click OK.

Parameter	Description
Alert Name	The name of the alert rule.
Alert Type	The type of the alert rule. Valid values: Alert for Used Quotas: The alert rule is created for quota usage. Alert for Available Quotas: The alert rule is created for the available quota.
Threshold Type	The type of the alert threshold. Valid values: Numeric Value: The alert threshold is a numeric value. Percentage: The alert threshold is a percentage.
Threshold Number	The alert threshold. You must set the threshold based on the settings of the Alert Type and Threshold Type parameters. If you set the Threshold Type parameter to Numeric Value, set the threshold based on the following requirements: If you set the Alert Type parameter to Alert for Used Quotas, and the quota usage reaches the specified threshold, an alert notification is sent. The alert threshold must be greater than the current usage of the quota. If you set the Alert Type parameter to Alert for Available Quotas, and the available quota is smaller than the specified threshold, an alert notification is sent. The alert threshold must be smaller than the current available quota. If you set the Threshold Type parameter to Percentage, set the threshold based on the following requirements: If you set the Alert Type parameter to Alert for Used Quotas, and the quota usage reaches the specified threshold, an alert notification is sent. Value range: (50%, 100%]. If you set the Alert Type parameter to Alert for Available Quotas, and the available quota is smaller than the specified threshold, an alert notification is sent. Value range: (0%, 50%].
Alert Callback	The webhook URL. Quota Center sends an alert notification to the specified URL by using an HTTP POST request. For more information about the examples and parameters of alert callback requests, see What is the request content of an alert callback? Note By default, Quota Center sends an alert notification about 15 minutes after the specified alert threshold is reached. If your alert callback is integrated with the webhook of a DingTalk chatbot, you must set the custom keyword of the DingTalk chatbot to Alert and then copy the webhook URL as the URL of the alert callback.

In the Actions column of the general quota that you want to manage, click Alert Settings.
In the Alerts dialog box, you can view the created alert rules. You can also click View, Modify, or Delete in the Actions column.

Create a quota template

In scenarios where a quota template is added and in the Enabled state, if new members are added to a resource directory, the system automatically applies the quota template to the new members. Existing members are not affected. You can use a quota template to apply for increases on multiple quotas at a time. This automated approach can improve the efficiency of quota management across your organization.

Prerequisites:

An enterprise administrator account is used.
A resource directory is enabled. For more information, see Enable a resource directory.
A quota template is enabled. For more information, see the "Enable a quota template" section in this topic.

You can add a quota to a quota template by using one of the following methods:

Use the Quota Center console. For more information, see Add a quota to a quota template.
Use the VPC console.

Procedure (VPC console)

Log on to the VPC console.
In the left-side navigation pane, choose O&M and Monitoring > Quota Management.
On the Quota Management page, click the VPC tab in the Service section. In the Quota Type section, select the type of quota that you want to manage.
