有了 Looker (Google Cloud Core)，您就能輕鬆在 Google Cloud 控制台佈建、設定及管理 Looker 執行個體，過程簡便又順暢。您也可以透過控制台執行部分執行個體管理工作。
Looker (Google Cloud Core) 執行個體是由 Google 託管在 Google Cloud。Looker (Google Cloud Core) 不適用於客戶代管或多雲端環境。
Looker (Google Cloud Core) 版本
Looker (Google Cloud Core) 提供多種版本。每個版本類型提供的功能不同，價格也不同。建立 Looker (Google Cloud Core) 執行個體時，請選擇符合需求的版本。執行個體建立後，就無法變更版本類型。您也可以為預備和測試環境，佈建、設定及管理相同版本類型的非正式環境執行個體。如要瞭解如何設定非正式環境執行個體，請參閱本頁的「模擬環境和測試」一節。
Standard 版
標準版專為小型團隊和中小型企業打造，最多可有 50 位內部平台使用者。除了現有的許多 Looker (Google Cloud Core) 功能外，「標準」版本還提供下列新功能：
- Google Cloud Identity 存取權管理和簡化的 BigQuery 連線。
- 每月最多可支援 1,000 項查詢相關的 Looker (Google Cloud Core) API 呼叫，以及 1,000 項管理相關的 Looker (Google Cloud Core) API 呼叫。如要進一步瞭解 API，請參閱「使用 Looker (Google Cloud Core) API」一節。
標準版可透過年度合約購買。

- 每月 100,000 項查詢相關 Looker (Google Cloud Core) API 呼叫，以及每月 10,000 項管理相關 Looker (Google Cloud Core) API 呼叫。如要進一步瞭解 API，請參閱本頁面的「使用 Looker (Google Cloud Core) API」一節。
Enterprise 版本可透過年約購買。
Embed 版本
嵌入版本除了具備企業版本的所有功能，還提供下列服務：
- 簽署的嵌入

Embed 版本可透過年度合約購買。
非正式環境執行個體
如要使用測試或測試執行個體，請按照建立 Looker (Google Cloud Core) 執行個體的標準程序，建立非正式環境執行個體，並選取適當的非正式環境版本。這個非正式版執行個體的帳單與其他 Looker (Google Cloud Core) 執行個體相同。詳情請參閱 Looker (Google Cloud Core) 定價頁面。
非正式環境執行個體版本與正式環境執行個體可用的版本相同，包括：
非正式版提供的功能與正式版相同。非正式環境 Looker (Google Cloud Core) 執行個體也可以與正式環境執行個體使用相同的網路連線類型。所有環境都具備相同功能，因此您可以將暫存環境設定為與實際工作環境相符，並在部署至實際工作執行個體前測試更新。
非正式環境執行個體的特性
以下是關於非正式版 Looker (Google Cloud Core) 執行個體的注意事項：
- 非正式環境執行個體不在任何 Google 服務水準協議的涵蓋範圍內。
- 水平擴展不屬於非正式環境用途。如要分散執行個體負載，並為實際工作環境用例在多個 Looker (Google Cloud Core) 執行個體中提供特定地理位置分配，您需要購買現有實際工作環境 Looker (Google Cloud Core) 版本的其他執行個體。
- 非正式環境 Looker (Google Cloud Core) 執行個體無法取代正式環境執行個體，也不得用於正式環境。
- 所有正式和非正式環境的 Looker (Google Cloud Core) 執行個體都遵循相同的發布週期。您可以設定非正式版執行個體的維護設定，與正式版執行個體的維護設定相符。
試用執行個體
如要試用 Looker (Google Cloud Core)，您可以建立試用版 Standard、Enterprise 或 Embed 執行個體，這些執行個體提供的功能支援與對應的正式版相同。試用版有下列限制：
- 試用版執行個體的效期為 90 天。90 天過後，您必須刪除或升級執行個體。
- 您無法直接將試用版執行個體升級為非試用版。如要升級，您必須建立新的執行個體，然後從試用執行個體匯入資料。
- 每個 Google Cloud 專案和 Google Cloud 區域的組合，每種版本類型只能有一個有效試用方案。
- 試用版不含 Looker Studio Pro 授權。
