配额用于指定您可以使用的可计数共享资源的数量。配额由 Cloud Workstations 等 Google Cloud 服务定义。
系统限制是无法更改的固定值。
Google Cloud 使用配额来帮助确保公平性并减少资源使用和可用性的激增。配额用于限制您的 Google Cloud 项目可使用的Google Cloud 资源的数量。配额适用于一系列资源类型，包括硬件、软件和网络组件。例如，配额可以限制对某项服务的 API 调用次数、您的项目并发使用的负载均衡器数量或者您可以创建的项目数量。配额可以防止服务过载，从而保护Google Cloud 用户社区。配额还可以帮助您管理自己的 Google Cloud 资源。

Quotas are defined by Google Cloud services such as Cloud Workstations.\n- *System limits* are fixed values that cannot be changed.\n\nGoogle Cloud uses quotas to help ensure fairness and reduce\nspikes in resource use and availability. A quota restricts how much of a\nGoogle Cloud resource your Google Cloud project can use. Quotas\napply to a range of resource types, including hardware, software, and network\ncomponents. For example, quotas can restrict the number of API calls to a\nservice, the number of load balancers used concurrently by your project, or the\nnumber of projects that you can create. Quotas protect the community of\nGoogle Cloud users by preventing the overloading of services. Quotas also\nhelp you to manage your own Google Cloud resources.\n\nThe Cloud Quotas system does the following:\n\n- Monitors your consumption of Google Cloud products and services\n- Restricts your consumption of those resources\n- Provides a way to [request changes to the quota value](/docs/quotas/help/request_increase) and [automate quota adjustments](/docs/quotas/quota-adjuster)\n\nIn most cases, when you attempt to consume more of a resource than its quota\nallows, the system blocks access to the resource, and the task that\nyou're trying to perform fails.\n\nQuotas generally apply at the Google Cloud project\nlevel. Your use of a resource in one project doesn't affect\nyour available quota in another project. Within a Google Cloud project, quotas\nare shared across all applications and IP addresses.\n\n\nThere are also *system limits* on Cloud Workstations resources.\nSystem limits can't be changed.\n\nAllocation quotas\n-----------------\n\nThese allocation quotas are per region per project and are released when you\nrelease the resource. These quotas don't reset over time.\n\nThe default Cloud Workstations resource limits per region per project are as\nfollows:\n\nRate quotas for API requests\n----------------------------\n\nThe following quotas specify the per project rate quota for Cloud Workstations API\nread and write requests:\n\nSystem limits\n-------------\n\nCloud Workstations enforces the following system limits,\nwhich can't be changed:\n\nTo restrict the number of workstations per configuration, see\n[Limit the number of workstations per developer](/workstations/docs/limit-workstations-per-developer).\n\nQuotas needed for workstation VMs\n---------------------------------\n\nFor the virtual machines (VMs) that workstations run on, you must allocate the\nfollowing resources:\n\n- CPU quotas\n- Persistent Disk quotas\n- If the VMs have external IP addresses, you need IP address quotas\n- Sufficient space in your Virtual Private Cloud (VPC) for the\n internal IP address for the VM\n\n To use a workstation configuration, make sure that there are sufficient IP\n addresses available in your VPC. To calculate how many IP\n addresses need to be available, add these values:\n - Start by adding `1` for each concurrently running workstation that you expect to create using this configuration.\n - If you enabled [**Quick start workstations**](/workstations/docs/create-configuration#configure_basics), also add the value that you specified for the **Quick start pool size**.\n - Lastly, add `1` for the IP address used to establish a connection between the Cloud Workstations controller and your VPC.\n\nRequest a quota adjustment\n--------------------------\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase)."]]
