Allocation quotas


This document lists the allocation quotas that apply to Compute Engine.

Allocation quotas

Allocation quotas, also known as resource quotas, define the number of resources that your project has access to. Compute Engine enforces allocation quotas on resource usage for various reasons. For example, quotas help to protect the community of Google Cloud users by preventing unforeseen spikes in usage. Google Cloud also offers free trial quotas that provide limited access for projects to help you explore Google Cloud on a free trial basis.

Not all projects have the same quotas. As you increasingly use Google Cloud over time, your quotas might increase accordingly. If you expect a notable upcoming increase in usage, you can proactively request quota adjustments from the Quotas page in the Google Cloud console.

For information specific to quotas for rate limits for the Compute Engine API, see API quota.

Quotas and resource availability

Allocation quotas are the maximum number of resources you can create of that resource type, if those resources are available. Quotas don't guarantee that resources are always available. If a resource is not available, or if the region you choose is out of the resource, you can't create new resources of that type, even if you have remaining quota in your region or project. For example, you might still have quota to create external IP addresses in us-central1, but there might not be available IP addresses in that region.

Similarly, even if you have a regional quota, a resource might not be available in a specific zone. For example, you might have quota to create VM instances in region us-central1, but you might not be able to create VM instances in the zone us-central1-a if the zone is depleted. In such cases, try creating the same resource in another zone, such as us-central1-f. To learn more about your options if zonal resources are depleted, see the documentation for troubleshooting resource availability.

Allocation quotas

When planning your VM instance needs, you should consider several quotas that affect how many VM instances you can create.

Regional and global quotas

VM quotas are managed at the regional level. VM instance, instance group, disk quotas, and CPU can be consumed by any VM in the region, regardless of zone. For example, CPU quota is a regional quota, so there is a different limit and usage count for each region. To launch an n2-standard-16 instance in any zone in the us-central1 region, you need enough quota for at least 16 CPUs in us-central1.

Networking and load balancing quotas are required to create firewalls, load balancers, networks, and VPNs. These quotas are global quotas that don't depend on a region. Any region can use a global quota. For example, in-use and static external IP addresses assigned to load balancers and HTTP(S) proxies consume global quotas.

VM instances

The VM instances quota is a regional quota and limits the number of VM instances that can exist in a given region, regardless of whether the VM is running. This quota is visible in the Google Cloud console on the Quotas page. Compute Engine automatically sets this quota to be 10 times your regular CPU quota. You don't need to request this quota. If you need quota for more VM instances, request more CPUs because having more CPUs increases VM instance quota. The quota applies to both running and non-running VMs, and to normal and preemptible instances.

Instance groups

To use instance groups, you must have available quota for all the resources that the group uses (for example, CPU quota) and available quota for the group resource itself. Depending on the type of group that you create, the following group resource usage quotas apply:

Service type Service quota
Regional (multi-zone) managed instance group Regional instance group managers
Zonal (single-zone) managed instance group Both of:
  • Instance group managers
  • Instance groups
Unmanaged (single-zone) instance group Instance groups
Regional (multi-zone) autoscaler Regional autoscalers
Zonal (single-zone) autoscaler Autoscalers

Disk quotas

The following persistent disk and local SSD quotas apply on a per-region basis:

  • Local SSD per machine family (GB). This quota is the total combined size of local SSD disk partitions you can attach to VMs in a region based on the machine type of each VM. Local SSD is a fast, ephemeral disk that should be used for scratch, local cache, or processing jobs with high fault tolerance because the disk is not intended to survive VM instance reboots. Local SSD partitions are sold in increments of 375 GB and up to 24 local SSD partitions can be attached to a single VM. In the gcloud CLI and the API, this quota is referred to as LOCAL_SSD_TOTAL_GB_PER_VM_FAMILY.

  • Persistent disk standard (GB). This quota is the total size of standard persistent disks that can be created in a region. As described in Optimizing persistent disk and local SSD performance, standard persistent disks offer lower IOPS and throughput than SSD persistent disks or local SSD. It is cost effective when used as large durable disks for storage, as boot disks, and for serial write processes like logs. Standard persistent disks are durable and are available indefinitely to attach to a VM within the same zone. In the gcloud CLI and the API, this quota is referred to as DISKS_TOTAL_GB. This quota also applies to regional standard persistent disks, but regional disks consume twice the amount of quota per GB due to replication in two zones within a region.

  • Persistent disk SSD (GB). This quota is the total combined size of SSD-backed persistent disks partitions that can be created in a region. SSD-backed persistent disks have multiple replicas and, as described in Block storage performance, offer higher IOPS and throughput than standard persistent disks. SSD-backed persistent disks are available indefinitely to attach to a VM within the same zone. In the gcloud CLI and the API, this quota is referred to as SSD_TOTAL_GB. This quota is separate from local SSD. This quota applies to the following disk types:

    • Zonal and regional SSD persistent disk
    • Zonal and regional balanced persistent disk

    Regional persistent disks consume twice the amount of quota per GB due to replication in two zones within a region.

CPU quota limits

CPU quota is the total number of virtual CPUs across all of your VM instances in a region. CPU quotas apply to running VMs and VM reservations. Both predefined and preemptible VMs consume this quota.

To help protect Compute Engine systems and other users, some new accounts and projects also have a global CPUs (All Regions) quota. That quota applies to all regions and is measured as a sum of all your vCPUs in all regions.

For example, if you have 48 vCPUs remaining in a single region such as us-central1 but only 32 vCPUs remaining for the CPUs (All Regions) quota, you can launch only 32 vCPUs in the us-central1 region, even though there is remaining quota in the region. This is because you reach the CPU (All Regions) quota and need to delete existing instances before you can launch new instances.

E2 and N1 machine types share a CPU quota pool. Unless otherwise noted, all other machine types have unique, separate CPU quota pools.

If you are using committed use discounts for your VMs, you must have committed use discount quota before you purchase a committed use discount contract.

Machine type Quota pool CPU quota name Committed CPU quota name
N1 shared pool CPUS Committed_CPUS
E2 shared pool CPUS Committed_E2_CPUS
N2 separate pool N2_CPUS Committed_N2_CPUS
N2D separate pool N2D_CPUS Committed_N2D_CPUS
T2D separate pool T2D_CPUS Committed_T2D_CPUS
T2A separate pool T2A_CPUS Not available (N/A) for T2A
Z3 (Preview) separate pool CPUS_PER_VM_FAMILY Committed_Z3_CPUS
M1 separate pool M1_CPUS Committed_MEMORY-OPTIMIZED_CPUS
M2 separate pool M2_CPUS Committed_MEMORY-OPTIMIZED_CPUS
M3 separate pool M3_CPUS Committed_M3_CPUS
H3 separate pool CPUS_PER_VM_FAMILY Committed_H3_CPUS
C2 separate pool C2_CPUS Committed_C2_CPUS
C2D separate pool C2D_CPUS Committed_C2D_CPUS
C3 separate pool C3_CPUS Committed_C3_CPUS
C3D separate pool CPUS_PER_VM_FAMILY Committed_C3D_CPUS
Preemptible VMs shared pool PREEMPTIBLE_CPUS Not available (N/A) for preemptible VMs

GPU quota

Similar to virtual CPU quota, GPU quota refers to the total number of virtual GPUs in all VM instances in a region. GPU quotas apply to running VMs and VM reservations. Both predefined and preemptible VMs consume this quota.

Check the Quotas page to ensure that you have enough GPUs available in your project, and to request a quota increase. In addition, new accounts and projects have a global GPU quota that applies to all regions.

When you request a GPU quota, you must request a quota for the GPU models that you want to create in each region, and an additional global quota (GPUs (all regions)) for the total number of GPUs of all types in all regions. Request preemptible GPU quota to use those resources.

Allocation quotas for preemptible resources

To use preemptible CPUs or GPUs attached to preemptible VM instances, or to use local SSDs attached to preemptible VM instances, you must have available quota in your project for those respective resources.

You can request special preemptible quotas for Preemptible CPUs, Preemptible GPUs, or Preemptible Local SSDs (GB). However, if your project does not have preemptible quota, and you have never requested preemptible quota, you can consume standard quota to launch preemptible resources.

After Compute Engine grants you preemptible quota in a region, all preemptible instances automatically count against preemptible quota. As this quota is depleted, you must request preemptible quota for those resources.

External IP addresses

You must have enough external IP addresses for every VM that needs to be directly reachable from the public internet. Regional IP quota is for assigning IPv4 addresses to VMs in that region. Global IP quota is for assigning IPv4 addresses to global networking resources such as load balancers. Google Cloud offers different types of IP addresses, depending on your needs. For information about costs, refer to External IP address pricing. For information about quota specifics, see Quotas and limits.

  • In-use external IP addresses. Includes both ephemeral and static IP addresses that are being used by a resource.

  • Static External IP addresses: External IP addresses reserved for your resources that persist through machine restarts. You can register these addresses with DNS and domain provider services to provide a user-friendly address. For example, www.example-site.com.

  • Static Internal IP addresses: Static internal IP addresses let you reserve internal IP addresses from the internal IP range configured in the subnet. You can assign those reserved internal addresses to resources as needed.

Quota rollouts

Occasionally, Google Cloud changes the default quota for resources and APIs. These changes take place gradually. During the rollout of a new default quota, the maximum quota that appears in the Google Cloud console might not reflect the actual maximum quota that is available to you.

For example, suppose that Google Cloud changes the default maximum quota for firewall rules from 200 to 300, and you use the Google Cloud console to view your quota, you might see the new quota of 300, even though your actual quota is 200 until the rollout completes.

For information about ongoing quota rollouts, see known issues. If no issues are described, no quota rollouts are ongoing.

If a quota rollout is ongoing and you want to confirm the actual maximum quota that is available to you, use the Google Cloud CLI to check your quota. If you need more quota than you have access to, submit a quota increase request.
