Quotas and limits

This document lists the quotas and limits that apply to Network Connectivity Center and Router appliance.

To change a quota, see requesting additional quota.

Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.

The Cloud Quotas system does the following:

  • Monitors your consumption of Google Cloud products and services
  • Restricts your consumption of those resources
  • Provides a way to request changes to the quota value

In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.

Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.

There are also system limits on Network Connectivity Center resources. System limits can't be changed.

Quotas

This section lists quotas that apply to Network Connectivity Center and Router appliance.

Network Connectivity Center quotas

Quotas that apply to network routes for Cloud Router also apply to routes for Network Connectivity Center hubs and spokes. For more information, see Cloud Router Quotas and limits.

Item Quota Notes
Number of hubs per project Quota Per project, global
Number of Cloud VPN tunnel spokes per project per region Quota Per project in each region; only HA VPN tunnels are supported
Number of Cloud Interconnect VLAN attachment spokes per project per region Quota Per project in each region
Number of Router appliance spokes per project per region Quota Per project in each region
Number of VPC spokes per project Quota Includes VPC spokes (edge and center spokes combined) even if they are not connected to any hub.

Number of active VPC spokes per hub

 Quota

Only applicable to VPC spokes that have been accepted into a hub; not applicable to VPC spokes that are pending review or that have been rejected.

Number of subnet routes per hub route table

 Quota Only applicable to hubs with VPC spokes

Router appliance quotas

Quotas that apply to network routes for Cloud Router also apply to routes for Router appliance spokes attached to Network Connectivity Center hubs.

For more information, see Cloud Router quotas.

Limits

This section lists limits that apply to Network Connectivity Center and Router appliance.

Network Connectivity Center limits

Network Connectivity Center enforces the following usage limits.

Item Value
Number of VPN tunnels that can be linked to a spoke 8
Number of VLAN attachments that can be linked to a spoke 6
Number of router appliance instances that can be linked to a spoke 8
Number of active VPC spokes per hub 250
Maximum number of VPC spokes (active and inactive) per hub 1,000
Number of export filters per spoke 16
Maximum number of routing VPCs supported per Network Connectivity Center hub 40
Number of dynamic routes per hub route table 500

Router appliance limits

The following limits for Cloud Router also apply to Router appliance:

  • The maximum number of Cloud Routers per combination of VPC network and region
  • The maximum number of BGP peers for each Cloud Router in a given VPC network and region

For more information, see Cloud Router limits.

Manage quotas

Network Connectivity Center enforces quotas on resource usage for various reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Quotas also help users who are exploring Google Cloud with the free tier to stay within their trial.

All projects start with the same quotas, which you can change by requesting additional quota. Some quotas might increase automatically based on your use of a product.

Permissions

To view quotas or request quota increases, Identity and Access Management (IAM) principals need one of the following roles.

Task Required role
Check quotas for a project One of the following:
Modify quotas, request additional quota One of the following:
  • Project Owner (roles/owner)
  • Project Editor (roles/editor)
  • Quota Administrator (roles/servicemanagement.quotaAdmin)
  • A custom role with the serviceusage.quotas.update permission

Check your quota

Console

  1. In the Google Cloud console, go to the Quotas page.

    Go to Quotas

  2. To search for the quota that you want to update, use the Filter table. If you don't know the name of the quota, use the links on this page instead.

gcloud

Using the Google Cloud CLI, run the following command to check your quotas. Replace PROJECT_ID with your own project ID.

    gcloud compute project-info describe --project PROJECT_ID

To check your used quota in a region, run the following command:

    gcloud compute regions describe example-region

Errors when exceeding your quota

If you exceed a quota with a gcloud command, gcloud outputs a quota exceeded error message and returns with the exit code 1.

If you exceed a quota with an API request, Google Cloud returns the following HTTP status code: 413 Request Entity Too Large.

Request additional quota

To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.

Console

  1. In the Google Cloud console, go to the Quotas page.

    Go to Quotas

  2. On the Quotas page, select the quotas that you want to change.
  3. At the top of the page, click Edit quotas.
  4. For Name, enter your name.
  5. Optional: For Phone, enter a phone number.
  6. Submit your request. Quota requests take 24 to 48 hours to process.

Resource availability

Each quota represents a maximum number for a particular type of resource that you can create, if that resource is available. It's important to note that quotas don't guarantee resource availability. Even if you have available quota, you can't create a new resource if it is not available.

For example, you might have sufficient quota to create a new regional, external IP address in the us-central1 region. However, that is not possible if there are no available external IP addresses in that region. Zonal resource availability can also affect your ability to create a new resource.

Situations where resources are unavailable in an entire region are rare. However, resources within a zone can be depleted from time to time, typically without impact to the service level agreement (SLA) for the type of resource. For more information, review the relevant SLA for the resource.
