扩展云模板
创建和测试示例应用程序的基本
Automation Assembler
模板后，可将其扩展到多层应用程序，之后该应用程序可部署到开发、测试环境，最终部署到生产环境。 要扩展云模板，请添加以下增强功能。
- 用于集群应用程序服务器以增加容量的选项
- 应用程序服务器前面的公用网络和负载均衡器
- 具有存档存储的备份服务器
- 单击云模板，然后打开 WordPress-BP 云模板。基本模板将显示在设计画布和代码编辑器中。
- 使用代码示例和图作为指导进行添加和更改。您可以使用 GUI 将新资源拖到画布（如负载均衡器），然后在代码编辑器中完成配置。
- 添加count输入提示，以使 WordPress 应用程序服务器加入集群。
- 添加云不可知负载均衡器。
- 将负载均衡器连接到 WordPress 应用程序服务器集群。
- 添加云不可知的备份计算机。
- 将备份计算机连接到专用/内部网络。
- 添加云不可知的公用/外部网络。
- 将负载均衡器连接到公共网络。
- 添加一个云不可知的存储卷，用作存档磁盘。
- 将存档磁盘连接到备份计算机。
- 为存档磁盘速度添加输入提示。
- 使用与基本云模板相同的方式进行部署、测试和更改。您可以更新现有部署，甚至部署新实例，以便可以比较部署。目标是实现可用于生产部署的可靠、可重用模板。
