Quotas and limits

This document lists the quotas and system limits that apply to Cloud Next Generation Firewall.

  • Quotas have default values, but you can typically request adjustments.
  • System limits are fixed values that can't be changed.

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:

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.

For more information, see the Cloud Quotas overview.

There are also system limits on Cloud NGFW resources. System limits can't be changed.

Quotas

This section lists the quotas that apply to Cloud Next Generation Firewall.

To monitor per-project quotas that use Cloud Monitoring, set up monitoring for the metric serviceruntime.googleapis.com/quota/allocation/usage on the Consumer Quota resource type. Set additional label filters (service, quota_metric) to get to the quota type. For information about monitoring quota metrics, see Chart and monitor quota metrics. Each quota has a limit and a usage value.

Unless noted otherwise, to change a quota, see Request a quota adjustment.

Per firewall policy

The following table highlights Cloud NGFW quotas that are per firewall policy resource:

Quota Description
Hierarchical firewall policies
Rule attributes per hierarchical firewall policy This quota is the sum of rule attributes from all rules in a hierarchical firewall policy.

For more information, see Rule attribute count for a firewall policy and Computation of rule attribute count.
Domain names (FQDNs) per hierarchical firewall policy The number of domain names that you can include in all rules of a hierarchical firewall policy. This quota is the sum of all source domain names from all ingress rules in the policy plus the sum of all destination domain names from all egress rules in the policy.
Global network firewall policies
Rule attributes per global network firewall policy The sum of rule attributes from all rules in a global network firewall policy.

For more information, see Rule attribute count for a firewall policy and Computation of rule attribute count.
Domain names (FQDNs) per global network firewall policy The number of domain names that you can include in all rules of a global network firewall policy. This quota is the sum of all source domain names from all ingress rules in the policy plus the sum of all destination domain names from all egress rules in the policy.
Regional network firewall policies
Rule attributes per regional network firewall policy The sum of rule attributes from all rules in a regional network firewall policy.

For more information, see Rule attribute count for a firewall policy and Computation of rule attribute count.
Domain names (FQDNs) per regional network firewall policy The number of domain names (FQDNs) that you can include in all rules of a regional network firewall policy: This quota is the sum of all source domain names from all ingress rules in the policy plus the sum of all destination domain names from all egress rules in the policy.

Rule attribute count for a firewall policy

Each firewall policy supports a maximum total number of attributes from all rules in the policy. To determine the rule attribute count for a given firewall policy, describe the policy. For directions, see the following:

For details about computation of rule attributes, see Computation of rule attribute count.
