Quotas and limits
This document lists the quotas and limits that apply to Virtual Private Cloud (VPC) networking.
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 means 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 limits on VPC resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.
Quotas
To change a quota, see requesting additional quota.
Per project
This table highlights important global quotas for VPC resources in each project. For other quotas, see the Quotas page in the Google Cloud console.
To monitor per-project quotas using 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, including finding limit names and metric names, see Use quota
metrics. Each quota has a limit and a
usage value.

The following limits apply to VPC networks. These limits are
enforced by using quotas internally. When per-network limits are exceeded, you
see QUOTA_EXCEEDED
errors with the internal quota names.
Item | Limit | Notes |

Effective limits for per-peering group quotas
Each per-peering group quota has the concept of an effective limit. This section describes how the quota's effective limit is calculated. The effective limit is always greater than or equal to the value of the per-peering group quota's limit.
Most per-peering group quotas have a corresponding network quota—for
example, SUBNET_RANGES_PER_PEERING_GROUP
and SUBNET_RANGES_PER_NETWORK
. The
effective limit calculation described in this section applies to all per-peering
group quotas, even those that do not have a corresponding per-network quota.
A per-peering group quota's effective limit is calculated in the following way:
Step 1. Select a VPC network. When VPC Network Peering is used, each network has its own peering group. A network's peering group consists of the VPC network itself and all other VPC networks that are directly connected to it through VPC Network Peering. Effective limit calculations are repeated for each per-peering group quota on a network by network basis.
Step 2. For the selected VPC network, find the greater of these limits:
- the limit for the per-peering group quota
- the limit for the corresponding per-network quota
If no corresponding per-network quota exists, use the per-peering group quota's limit.
Step 3. Create a list consisting of the greater of these two limits in each peer network:
- the limit for the per-peering group quota
- the limit for the corresponding per-network quota
If no corresponding per-network quota exists, use the per-peering group quota's limit.
Step 4. Find the smallest value from the list created by Step 3.
Step 5. Take the greater of the two values from Step 2 and Step 4. This number is the effective limit for the per-peering group quota from the perspective of the selected VPC network.
Effective limits example
Suppose that you have four VPC networks, network-a
,
network-b
, network-c
, and network-d
. Because there are four
VPC networks, there are also four peering groups, one from the
perspective of each network.
Suppose the network peering connections are as follows:
network-a
is peered withnetwork-b
, andnetwork-b
is peered withnetwork-a
network-a
is peered withnetwork-c
, andnetwork-c
is peered withnetwork-a
network-c
is peered withnetwork-d
, andnetwork-d
is peered withnetwork-c
Suppose the limits for two corresponding quotas are set as follows:
Network | Limit for INTERNAL_FORWARDING_RULES_PER_PEERING_GROUP |
Limit for INTERNAL_FORWARDING_RULES_PER_NETWORK |
---|---|---|
network-a |
500 | 600 |
network-b |
350 | 300 |
network-c |
300 | 300 |
network-d |
400 | 300 |
The effective limits for each INTERNAL_FORWARDING_RULES_PER_PEERING_GROUP
quota are as follows:

Manage quotas
Virtual Private Cloud 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.

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 increase or decrease most quotas, use the Google Cloud console. For more information, see Request a higher quota.
Console
- In the Google Cloud console, go to the Quotas page.
- On the Quotas page, select the quotas that you want to change.
- At the top of the page, click Edit quotas.
- For Name, enter your name.
- Optional: For Phone, enter a phone number.
- 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.
