正在設定以外掛程式為基礎的負載平衡器

雲端管理員可以利用 Google Cloud Platform (GCP) 外掛程式建立負載平衡器以支援自訂解決方案，包括高可用性。

您可以對負載平衡器組態的多個方面進行設定以支援特定需求。例如，這些功能可以支援為 SAP NetWeaver 和 SAP Hana 佈建基礎結構。透過此組態，可以在不同的可用性區域中部署不同的負載平衡器執行個體。

佈建負載平衡器之前，必須在 VMware Aria Automation 中設定適當的元件。

如果沒有 GCP 雲端帳戶，請建立一個。
設定類型模板和映像對應。
建立預設網路設定檔。
建立計算可用性區域並進行相應標記。透過這些標籤，您可以將執行個體和執行個體群組佈建到範本中的特定可用性區域。

完成這些步驟後，可以開啟 Automation Assembler 中的設計索引標籤，建立範本。建置範本時，請考慮以下因素：

範本應使用健全狀況檢查、執行個體、執行個體群組、後端服務、轉送規則和防火牆的規格對適當的負載平衡器組態進行建模。
範本應指定虛擬機器及其部署所在的可用性區域。

設定內部 TCP 負載平衡器

下列範本顯示如何為購置設定內部 TCP 負載平衡器。若要部署此範本，您需要滿足以下條件：

網路
子網路 IP CIDR 範圍
內部負載平衡器的虛擬 IP (VIP) 位址
這是您為轉送規則設定的位址。請參閱 Google Cloud 說明文件，瞭解如何為 NetWeaver和 SAP Hana 保留 IP 位址。

此範例範本使用配置協助程式為多個資源提供配置邏輯。該範本包含兩個執行個體、執行個體群組、一個健全狀況檢查資源、一個防火牆資源、一個後端服務資源和一個轉送規則資源。

部署此範本後，可以登入 Google Cloud 主控台，篩選並選擇要新增到執行個體群組的執行個體。只有與執行個體群組位於同一區域中的執行個體才會顯示為選項。請參閱 Google Cloud 主控台中的執行個體群組。
