瞭解託管的用量等級、配額和定價
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
Firebase Hosting 的價格取決於專案的下列用量：
Hosting 配額是專案層級，而非網站或管道層級。只要將專案升級至 Blaze 計費方案，即可取得更多付費儲存空間和資料傳輸量。進一步瞭解 Firebase Hosting 的配額和價格。
建議您在 Google Cloud 控制台中為專案設定預算快訊。
在Hosting控制台Firebase中監控儲存空間層級和資料傳輸層級：
瞭解 Hosting 儲存空間
將新內容部署至網站時，您會建立「發布」版本，指向網站特定版本的內容和設定。Firebase 會儲存與每個版本相關聯的檔案 (包括新版本和保留的舊版本)。這些檔案會決定專案的 Hosting 儲存空間用量層級。
這個Hosting儲存空間是獨立的，與 Firebase 專案的其他儲存空間 (例如Cloud Storage for Firebase或資料庫儲存空間) 無關。
請注意，Hosting 的個別檔案大小上限為 2 GB。
Hosting 儲存空間配額
最多 10 GB 的Hosting內容儲存空間免付費。
控管「Hosting」儲存空間的使用情況
如要控管 Hosting 儲存空間用量，可以採取下列行動：
瞭解 Hosting 資料移轉
當 Hosting 提供您網站的其中一項資源時，資料會從我們的 CDN 傳輸給您的使用者。要求的資源可能已存在於我們的 CDN 快取中 (快取命中)，或需要來自 Hosting 後端 (快取失敗)。如果要求的內容可快取至 CDN，系統就會快取。快取命中和未命中都會計入專案的Hosting資料傳輸用量。
Hosting資料移轉配額
每個 Hosting 網站都會自動由全球 CDN 免費備份。
每月最多 10 GB 的資料可從 CDN 免費轉移給使用者。
控管 Hosting 資料移轉作業的使用情形
如要控管 Hosting 資料傳輸用量，可以採取下列措施：
微調內容的用戶端快取，讓瀏覽器不必向 CDN 要求資源。如要進一步瞭解快取，請參閱網頁開發人員說明文件。
避免載入實際不需要顯示的圖片和影片。
建立服務工作人員來處理特定要求。
如果透過預留的 Hosting 網址載入 Firebase SDK，請務必詳閱這些網址的預留命名空間相關重要資訊。

Every Hosting site is automatically\n backed by our global CDN at no charge.\n\nYour Hosting quota is project-level, not site-level or channel-level. You\ncan upgrade your project to the Blaze billing plan to unlock additional paid\nstorage and data transfer levels. Learn more about\n[quotas and pricing for Firebase Hosting](/pricing#hosting).\n\nWe recommend setting up\n[budget alerts](/docs/projects/billing/avoid-surprise-bills#set-up-budget-alert-emails)\nfor your project in the Google Cloud console.\n\nMonitor both your Hosting storage level and data transfer level in the\nFirebase console:\n\n- Visit the [*Usage*](//console.firebase.google.com/project/_/hosting/usage)\n dashboard in the *Hosting* section of the console. \n\n You can view the usage levels for different billing periods as well as for all\n your Hosting sites or for each site.\n\n- Visit your project's\n [*Usage and billing* dashboard](//console.firebase.google.com/project/_/usage)\n in the console.\n\n| When your project is on the Blaze pricing plan, [**set up budget alerts**](/docs/projects/billing/avoid-surprise-bills#set-up-budget-alert-emails) using the console. You can use the [Blaze plan calculator](/pricing#blaze-calculator) to estimate your monthly costs.\n|\n| Be aware that **budget alerts do *not* cap your usage or\n| charges** --- they are *alerts* about your costs so that you can\n| take action, if needed. For example, you might consider\n| [using\n| budget notifications to programmatically disable Cloud Billing on a\n| project](https://cloud.google.com/billing/docs/how-to/disable-billing-with-notifications).\n\nUnderstand Hosting storage\n\nWhen you deploy new content to your site, you create a \"release\" that points to\na specific version of content and configuration for your site. The files\nassociated with each release (both new releases and any retained previous\nreleases) are stored by Firebase. These files make up your project's Hosting\nstorage usage level.\n\nThis Hosting storage is independent and unrelated to any other storage for\nyour Firebase project (like Cloud Storage for Firebase or database storage).\n\nNote that Hosting has a maximum size limit of 2 GB for\nindividual files.\n\nQuota for Hosting storage\n\nStorage for your Hosting content is at no cost up to\n10 GB.\n\n- If you are *not* on the Blaze plan, and you reach the\n 10 GB limit of no-cost Hosting storage, you won't be\n able to deploy new content to your sites. You'll need to\n [delete older releases](/docs/hosting/manage-hosting-resources#delete-release)\n or\n [upgrade to the Blaze plan](//console.firebase.google.com/project/_/overview?purchaseBillingPlan=metered).\n\n- If you are on the Blaze plan, and you reach the 10 GB\n limit of no-cost Hosting storage, you'll be billed $0.026 for each additional\n GB of Hosting storage.\n\nControl usage of Hosting storage\n\nTo control your Hosting storage usage, here are some things you can do:\n\n- [Set a limit](/docs/hosting/manage-hosting-resources#release-storage-settings)\n for the number of releases to keep.\n\n- [Manually delete](/docs/hosting/manage-hosting-resources#delete-release)\n specific releases.\n\n- Store larger files using [Cloud Storage for Firebase](/docs/storage), which\n offers a maximum size limit in the terabyte range for individual objects.\n\nUnderstand Hosting data transfer\n\nWhen Hosting serves one of your site's resources, data transfers from our\nCDN to your end user. The requested resource might already be available in our\nCDN cache (a cache hit) or it might need to come from the Hosting backend (a\ncache miss). If the requested content can be cached in the CDN, it will be. Both\ncache hits and misses count toward your project's Hosting data transfer\nusage.\n\nQuota for Hosting data transfer\n\nEvery Hosting site is automatically backed by our global CDN at no charge.\nData transfer from the CDN to your end users is at no cost up to\n10 GB/month.\n\n- If you are *not* on the Blaze plan, and you reach the\n 10 GB/month limit of no-cost data transfer, we\n offer a short grace period but then your sites will be disabled. Your sites\n will remain disabled until the start of the next month because data transfer\n billing is based on *monthly* usage levels. You can reenable your sites\n immediately by [upgrading to the\n Blaze plan](//console.firebase.google.com/project/_/overview?purchaseBillingPlan=metered).\n\n- If you are on the Blaze plan, and you reach the\n 10 GB/month limit of no-cost data transfer, you'll be\n billed $0.15 for each additional GB of data transferred that month.\n\nControl usage of Hosting data transfer\n\nTo control your Hosting data transfer usage, here are some things you can\ndo:\n\n- Fine-tune the client-side caching of your content so that browsers don't need\n to request a resource from the CDN. Learn more about caching in the\n [web developer documentation](//web.dev/http-cache/#cache-control).\n\n- Avoid loading images and videos that you don't actually need to display.\n\n- Create service workers to handle certain requests. \n\n If you load Firebase SDKs via reserved Hosting URLs, make sure to read\n important information about the\n [reserved namespace for these URLs](/docs/hosting/reserved-urls#reserved_urls_and_service_workers).\n\n Here are some resources to help you set up service workers, especially with a\n PWA:\n - Codelab: [Caching files with the service worker](//codelabs.developers.google.com/codelabs/pwa-caching-service-worker/index.html)\n\n - Documentation: [Service Worker Mindset](//web.dev/service-worker-mindset/#powerful-but-limited)"]]
