Power BI Premium - 這是什麼?Power BI Premium - what is it?

Power BI Premium 為您的組織或小組提供專門用來執行 Power BI 服務的資源,給您更可靠的效能和更大的資料磁碟區。Power BI Premium provides resources dedicated to running the Power BI service for your organization or team, giving you more dependable performance and larger data volumes. Premium 也可讓您廣泛發佈內容,不需要您為檢視者購買每個使用者授權。Premium also enables widespread distribution of content without requiring you to purchase per-user licenses for viewers.

您可以將工作區指派至進階容量來利用 Power BI Premium。You can take advantage of Power BI Premium by assigning workspaces to a Premium capacity. 「進階容量」是您的組織的專用資源。Premium capacity is a dedicated resource for your organization. 未指派至進階容量的工作區會放在共用容量中。For workspaces that are not assigned to a premium capacity, these will be in a shared capacity.

「共用容量」是您在 Power BI 中習慣於其他客戶共用的計算資源上執行工作負載的一種體驗。Shared capacity is the experience you are used to with Power BI, where your workloads run on computational resources shared by other customers. 在共用容量中,為了確保所有使用者的體驗品質,個別使用者會受到較多限制。In shared capacity, more limits are placed on individual users to ensure quality of the experience for all users.

  1. 進階容量內的項目Items within a Premium capacity

    • 需要有 Power BI Pro 授權才能 (以成員或管理員身分) 存取應用程式工作區並發佈應用程式。Accessing app workspaces (as members or admins) and publishing apps requires a Power BI Pro license.
    • 應用程式讀取者可以是 Power BI Pro 或免費使用者。App readers can be Power BI Pro or free users.
    • 需要有 Power BI Pro 授權才能共用,但收件者可以是 Power BI Pro 或免費使用者。Sharing requires a Power BI Pro license but recipients can be Power BI Pro or free users.
    • 不論是否有 Power BI Pro 或免費授權,儀表板收件者都可以設定資料警示。Whether they have a Power BI Pro or free license, dashboard recipients can set data alerts.
    • 內嵌用途的 REST API 會使用具有 Power BI Pro 授權的服務帳戶,而非使用者帳戶。REST APIs for embedding utilize a service account, with a Power BI Pro license, rather than a user.
  2. 共用容量中我的工作區My workspace in Shared capacity

    • 共用需要 Pro 授權。Sharing requires a Pro license. 收件者也需要 Pro 授權。Recipients also need Pro licenses.
  3. 共用容量中的應用程式工作區App workspaces in Shared capacity

    • 使用任何應用程式都需要有 Pro 授權。Any app usage requires Pro licenses.

容量層Capacity tiers

Power BI 中有兩種容量。There are two types of capacity within Power BI. 共用容量和 Power BI Premium 容量。Shared capacity and Power BI Premium capacity. 以下就來看看兩者的差異。Here is a look at what the differences are between them.

共用容量Shared capacity Power BI Premium 容量Power BI Premium capacity
重新整理的頻率Refresh rate 8/日8/day 不受限制Not restricted
使用專用的硬體隔離Isolation with dedicated hardware
企業散發至所有使用者Enterprise Distribution to all users
應用程式Apps 11
內嵌的 API 和控制項Embedded API and controls 22
在內部部署發佈 Power BI 報告Publish Power BI reports on-premises

1 應用程式中的免費使用者使用方式包括在 Web 和行動裝置中檢視內容、使用問與答、深入資訊摘要、Cortana、匯出至 CSV、Excel 和 PowerPoint。1 Free user consumption in apps includes viewing content in web and mobile, using Q&A, Quick Insights, Cortana, export to CSV, Excel and PowerPoint.

進階容量Premium capacity

若要開始使用 Power BI Premium 容量,您需要將工作區指派至容量。To start using a Power BI Premium capacity, you need to assign a workspace to a capacity. 如需有關如何將工作區指派至進階容量的詳細資訊,請參閱管理 Power BI PremiumFor more information on how to assign a workspace to a premium capacity, see Manage Power BI Premium.

當工作區有進階容量作為後盾時,您就能享用 Power BI Premium 的好處。When a workspace is backed by premium capacity, you enjoy the benefits of Power BI Premium.

  • 排程重新整理:以前,使用者在排程重新整理匯入的模型時,受限於每天 8x。Scheduled refreshes: users prior were limited to 8x a day when scheduling refreshes with imported models. Premium 工作區中的資料集已解除這項限制。This limitation is lifted for datasets in Premium workspaces. 這不適用於 DirectQuery 的排程快取重新整理設定。This does not apply to the scheduled cache refresh settings for DirectQuery. 這些在 Premium 容量和共用容量之間仍然相同。Those remain the same between Premium and Shared capacities.
  • 使用專用的硬體隔離 – 基於共用容量的本質,儘管我們已採取預防措施,容量中其他工作負載的資源需求還是可能影響報告和儀表板的效能。Isolation with dedicated hardware – by nature of shared capacity, the performance of your reports and dashboards may be impacted by the resource demands of other workloads in the capacity, despite our safeguards against it. 相反地,Premium 會隔離您的工作負載和不相關的工作負載,提供更一致又可靠的效能。Conversely, Premium provides more consistent, dependable performance for your workloads by isolating it from unrelated workloads.

如果應用程式有進階容量作為後盾 (也就是,從目前已指派至「進階」的應用程式工作區發佈),則組織中的任何使用者都可以使用已發佈的應用程式,而不論已指派給他們的授權。If an app is backed by premium capacity (i.e. it was published from an app workspace that is currently assigned to Premium), the published app can then be used by any user in your organization regardless of the license they are assigned. 這表示即使是 Power BI 免費使用者,也可以使用已發佈的應用程式。This means that even Power BI Free users can use those published apps.

共用容量Shared capacity

根據預設,您的工作區會在共用容量中。By default, your workspace will be in shared capacity. 這包括您的個人「我的工作區」,還有應用程式工作區。This includes your personal My workspace along with App workspaces. 「共用」容量是您在 Power BI 中習慣於其他客戶共用的計算資源上執行工作負載的一種體驗。A Shared capacity is the experience you are used to with Power BI, where your workloads run on computational resources shared by other customers.

進階容量節點Premium capacity nodes

Power BI Premium 適用於有不同 v 核心容量的節點設定。Power BI Premium is available in node configurations with different v-core capacities. 如需特定 SKU 供應項目和成本的詳細資訊,請參閱 Power BI 定價For more information about specific SKU offereings and cost, see Power BI pricing. 也提供成本計算機A cost calculator is also available. 如需內嵌的分析容量規劃的相關資訊,請參閱規劃 Power BI 企業部署白皮書For information regarding embedded analytics capacity planning, see Planning a Power BI Enterprise Deployment whitepaper.

  • P 節點可用於內嵌部署或服務部署P nodes can be used for embedded or service deployments
  • EM 節點只能用於內嵌部署EM nodes can be used for embedded deployments only
  • EM1 和 EM2EM1 and EM2
  • 只有 Office 365 全域系統管理員的使用者才能正常運作此資料表中的連結 - 其他人會收到 404 錯誤。Links in this table only operate properly for users who are Office 365 global admins - others receive a 404 error.

  • 前端核心負責 Web 服務、儀表板和報告文件管理、存取權限管理、排程、API、上傳和下載,大致上就是與使用者經驗有關的一切作業。The frontend cores are responsible for the web service, dashboard and report document management, access rights management, scheduling, APIs, uploads and downloads, and generally for everything that relates to the user experience.
  • 後端核心承擔重任:查詢處理、快取管理、執行 R 伺服器、資料重新整理、自然語言處理、即時摘要,以及在伺服器端轉譯報告和影像。The backend cores are responsible for the heavy lifting: query processing, cache management, running R servers, data refresh, natural language processing, real-time feeds, and server-side rendering of reports and images. 為了配合後端核心,也會保留一定數量的記憶體。With the backend cores, a certain amount of memory is reserved as well. 在處理大型資料模型,或大量的使用中資料集時,有足夠的記憶體就變得特別重要。Having sufficient memory becomes especially important when dealing with large data models or with a large number of active datasets.
