配額會指定您可使用的可計數共用資源數量。配額是由 Google Cloud 服務 (例如 Secure Web Proxy) 定義。
系統限制為固定值，無法變更。
Google Cloud 會使用配額來確保公平性，並減少資源使用量和可用性的尖峰情形。配額會限制 Google Cloud 專案可使用的Google Cloud 資源數量。配額適用於多種資源類型，包括硬體、軟體和網路元件。舉例來說，配額可以限制向服務發出的 API 呼叫數、專案並行使用的負載平衡器數量，或可建立的專案數量。限制配額可預防服務超載，進而保障Google Cloud 使用者社群的權益。配額也能協助您管理自己的 Google Cloud 資源。

Quotas are defined by Google Cloud services such as Secure Web Proxy.\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 Secure Web Proxy resources.\nSystem limits can't be changed.\n\nAllocation quotas\n\nThe following quotas don't reset over time and instead are released when you\nrelease the resource.\n\n| Usage limit | Value |\n|-----------------------------------------------------------|-------|\n| Secure Web Proxy instances defined per project per region | 5 |\n| URL lists defined per project per region | 10 |\n| Policies defined per project per region | 10 |\n\nTo display quotas for Secure Web Proxy instances for your project, in the Google Cloud console, go to the\n**Network Services API quotas** page.\n\n[Go to Network Services API quotas](https://console.cloud.google.com/apis/api/networkservices.googleapis.com/quotas)\n\nTo display quotas for policies for your project, in the Google Cloud console,\ngo to the **Network Security API quotas** page.\n\n[Go to Network Security API quotas](https://console.cloud.google.com/apis/api/networksecurity.googleapis.com/quotas)\n\nUsage limits\n\nSecure Web Proxy enforces the following usage limits:\n\n| Usage limit | Value |\n|--------------------------------------------|------------------|\n| Rules per policy | 500 |\n| CEL regular expression matchers per policy | 5 |\n| Maximum sub-expressions per rule | 5,000 |\n| Maximum entries per URL list | 2,500 |\n| Regular expression length | 100 characters |\n| Maximum matcher length | 2,048 characters |\n| Maximum characters per rule | 100,000 |\n| Maximum characters per policy | 1,000,000 |\n\nRequest a quota increase\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase)."]]
