可能不合常理，但事實上，「多租戶」表示相反的意思：多個租戶在一個實例中共享資源。對用戶來說，應用程式中的身份就像駕駛執照。例如，一張駕駛執照可以在不同的州駕駛（多個組織使用一個身份），而不是為每個州重新申請駕駛執照。
在設計初期，我們注意到這種混亂，並努力為你的應用程式和用戶改正過來。這是我們的設計：

這種模式為管理身份提供了靈活性和重用性，尤其對於 SaaS 應用程式而言。如果我們看看一些流行的 SaaS 應用程式，我們可以發現它們都可以適應這種模式。不同應用程式中「組織」這個詞可能不同，比如「工作區」、「團隊」等。但概念是相同的。
例如，在 Notion（流行的協作工具）中：
因此，用戶可以輕鬆在不同的工作區間切換，而不需切換賬戶或重新登錄，並且保持工作區間的隔離。轉化成 Logto 的模型，這意味著：
根據不同的角色，用戶在不同的工作區（組織）中可以擁有不同的權限。

對於用戶來說，他們可以享受真正的單點登入體驗。在組織之間切換就像在標籤之間切換一樣簡單。
SaaS 應用程式的一個優勢是它們標準化且可擴展。例如，你可以在 Notion 中快速創建一個新的工作區，並且即可使用。
當你的應用程式在增長時，你可能想要為每個組織添加更多角色和權限。例如，一個新的角色「訪客」和一個新的權限「invite:guest」。如果需要逐一更新所有現有組織，這可能是一場噩夢。
使用 Logto，你可以更新組織模版，所有現有組織都會自動更新。
在 Logto，我們對組織和 API 資源都使用相同的訪問控制模型（RBAC）。這意味著如果你熟悉 RBAC，不需要學習新的訪問控制模型。同時，它們彼此隔離，所以你可以用於不同的用例。
最令人興奮的部分是你可以同時使用它們。讓我們延伸一下 Notion 的例子：
大多數 Logto SDK 都支持這兩種類型的 RBAC。
差異
組織 RBAC 和 API 資源 RBAC 在以下方面不同：
構建一個 SaaS 應用程式是困難的，我們希望 Logto 可以幫助你專注於核心業務。如果你有任何問題或建議，不要猶豫給我們反饋。
