This document lists the quotas and system limits that apply to Service Directory.
- Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Service Directory.
- System limits are fixed values that cannot be changed.
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 Service Directory resources. System limits can't be changed.
Quotas
Service Directory has the following quotas:
- Namespaces per project per region
- Services per namespace
- Endpoints per service
- Registration requests per minute per region
- Lookup requests per minute per region
You can see your existing quotas and usage on the Quotas page.
Limits
General Service Directory limitations:
- There is no health-status or health-checking for endpoints. There
are two alternatives:
- Use internal load balancers for integrated health checking, and register the load balancer with Service Directory.
- Store individual endpoint health status as endpoint annotations in Service Directory.
Cloud DNS integration limits:
- The Cloud DNS integration only serves endpoints that are a valid IPv4 or IPv6 address. Any endpoints that are registered that do not have a valid IP address are ignored by DNS requests.
- SRV records cannot be customized. The symbolic service, protocol, TTL, weight, and priority are managed by Service Directory.
- Service and endpoint annotations are not served in DNS requests. If your service needs to make use of custom annotations, it should use HTTP support in Service Directory.
- You cannot add resource records to the Service Directory zone. Only resource records generated internally from existing Service Directory endpoints are allowed.
Manage quotas
Service Directory 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:

Check your quota
Console
- In the Google Cloud console, go to the Quotas page.
- 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_IDTo 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
- 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 a given 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.
