割り当ては、使用できるカウント可能な共有リソースの量を指定します。割り当ては、Cloud Tasks などの Google Cloud サービスによって定義されます。
システムの上限は固定値で、変更できません。
Google Cloud では、割り当てを使用して公平性を確保し、リソースの使用量と可用性の急増を抑えます。割り当ては、 Google Cloud プロジェクトで使用できるGoogle Cloud リソースの量を制限します。割り当ては、ハードウェア、ソフトウェア、ネットワーク コンポーネントなど、さまざまなリソースタイプに適用されます。たとえば、割り当てによって、サービスへの API 呼び出しの数、プロジェクトで同時に使用されるロードバランサの数、作成可能なプロジェクトの数を制限できます。割り当てを適用することで、サービスの過負荷を防ぎ、Google Cloud ユーザーのコミュニティを保護します。割り当ては、自組織で使用している Google Cloud リソースの管理にも役立ちます。

Quotas are defined by Google Cloud services such as Cloud Tasks.\n- *System limits* are fixed values that cannot be changed.\n\nQuotas\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\nThe following table describes the quotas for Cloud Tasks resources.\n\n| Resource | Console quota name | Default value | Description |\n|--------------------------|-----------------------------------------------|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Maximum number of queues | **Number of queues per region** | 1,000 per region | The total number of queues (for both HTTP and App Engine targets) that can exist in a project per region, including the default queue. Queues that process tasks for App Engine targets must be in the same region as the App Engine app. This is the quota for queues created using Cloud Tasks API methods. Any queues created using `queue.yaml`, however, are based on the older Task Queues method. These queues continue to have an initial quota of 100. |\n| API requests | **Requests per minute per region** | 6,000,000 per minute | The total number of API requests that can be made per minute. |\n| Force run task requests | **Run task requests per minute per region** | 60 per minute | The total number of [`run task`](/tasks/docs/reference/rest/v2/projects.locations.queues.tasks/run) requests per minute. This API is intended for manual debugging and is unrelated to normal task execution. |\n| List requests | **List group requests per minute per region** | 600 per minute | The total number of [`list tasks`](/tasks/docs/reference/rest/v2/projects.locations.queues.tasks/list), [`list queues`](/tasks/docs/reference/rest/v2/projects.locations.queues/list), and [`list locations`](/tasks/docs/reference/rest/v2/projects.locations/list) requests per minute. |\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase).\n\nSystem limits\n\n\nThere are also *system limits* on Cloud Tasks resources.\nSystem limits can't be changed.\n\nThe following table describes the system limits for Cloud Tasks.\n\n| Resource | Value | Description |\n|----------------------------------|------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Queue dispatch rate | 500 tasks per second per queue | The maximum rate at which tasks can be dispatched from a queue. To dispatch at higher rates, use multiple queues. |\n| Maximum task size | 1 MB | The maximum size of a task that can be added to a queue. |\n| Task deduplication window | Up to 24 hours | The time period during which adding a task with the same name as a recently deleted task will cause the service to reject it with an error. This is the length of time that task deduplication remains in effect after a task is deleted. |\n| Inactive queues | Inactive after 30 days | A queue is considered `INACTIVE` if no method calls are made to it from any API, and it has had no task dispatches for this period. |\n| Maximum task retention | 31 days | The time between when a task is added to a queue and when it is automatically deleted. |\n| Maximum schedule time for a task | 30 days from current date and time | The maximum amount of time in the future that a task can be scheduled. |\n| Queue re-creation | 7 days | The time you must wait after deleting a queue to re-create a queue with the same name. |"]]
