Windows Server AppFabric 是免费的，因此不涉及许可“成本” - 它被视为 Windows/.NET 框架的附加组件。 Azure AppFabric SDK 确实附带了一个许可证，其中说明了您可以重新分发的内容，但 Windows Server AppFabric 安装程序中的许可证屏幕会向您推荐 Windows 许可证。
但是，虽然 AppFabric 没有考虑到成本本身，如果您想要在 AppFabric 缓存中使用高可用性功能，所有缓存主机都必须运行 Windows Server Enterprise Edition。 此处（第 3 段）有更多详细信息，这也是请您参考安装指南（虽然刚刚再次通读安装指南，但我无法没有看到任何地方提到这个限制）。
Windows Server AppFabric is free, so there's no licensing 'cost' involved - it's treated as an add-on to Windows/the .NET framework. The Azure AppFabric SDK does come with a license which states what you can redistribute, but the licence screen in the Windows Server AppFabric installer refers you to the Windows licence.
However, while AppFabric has no cost implications in and of itself, if you want to use the high availability features in an AppFabric cache, all cache hosts must be running Windows Server Enterprise Edition. There are more details on this here (para. 3), this also refers you to the installation guide (although having just read through the installation guide again I couldn't see this restriction mentioned anywhere).
