Recently I started to use Microsoft Azure Free Trial and I have gone through the link 最近，我开始使用Microsoft Azure免费试用版，并且已经通过了链接

I created a VM with the help of references. 我在参考的帮助下创建了一个VM。 Also I read about Resource Group , Storage Account and Availability Set but I couldn't understand the requirement and differences among all. 我还阅读了有关资源组 ， 存储帐户和可用性集的信息，但我不了解其中的要求和区别。

Please be kind to explain the requirement and differences among Resource Group , Storage Account and Availability Set . 请友好解释资源组 ， 存储帐户和可用性集之间的要求和差异。

1 个解决方案

In my opinion, these three resources are the logic resources, solutions for some requirement. 我认为，这三种资源是逻辑资源，是某些需求的解决方案。

The Resource Group is the basic solution for you to manage other resources in the ARM module. 资源组是用于管理ARM模块中其他资源的基本解决方案。 As the definition shows: 如定义所示：

A container that holds related resources for an Azure solution. 一个容器，用于存放Azure解决方案的相关资源。 The resource group includes those resources that you want to manage as a group. 资源组包括您要作为组管理的那些资源。 You decide how to allocate resources to resource groups based on what makes the most sense for your organization 您可以根据对您的组织最有意义的决定来决定如何向资源组分配资源

The Storage Account , you can also think it as a logic group for storage, a storage solution. 存储帐户，您也可以将其视为存储的逻辑组，即存储解决方案。 It defines some types for different data requirement. 它为不同的数据需求定义了一些类型。 And finally, the data still will be stored in the physical disk. 最后，数据仍将存储在物理磁盘中。

Azure Storage offers a massively scalable object store for data objects, a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store. Azure存储提供用于数据对象的可大规模扩展的对象存储，用于云的文件系统服务，用于可靠消息传递的消息传递存储以及NoSQL存储。

The Availability Set , it's a solution for the high availability. 可用性集，它是高可用性的解决方案。 Create resources in the Availability Set. 在可用性集中创建资源。 It will help you avoid some accidents without downtime. 这将帮助您避免意外事故而不会造成停机。 Also, it can Prevent some erroneous operations from expanding with the update domain and fault domain. 此外，它还可以防止某些错误操作随更新域和故障域而扩展。 In one word, it provides redundancy to your application. 一言以蔽之，它为您的应用程序提供了冗余。

As you ask in the comment, first, when you create the VM, the resource group is necessary. 如您在注释中所要求的，首先，在创建VM时，资源组是必需的。 But the Availability Set is not necessary, it just created for the high availability. 但是可用性集不是必需的，它只是为高可用性而创建的。 You can create it or not, all dependant on your requirement. 您是否可以创建它，都取决于您的要求。

For the storage account, there are two points I think you should pay attention to. 对于存储帐户，我认为您应注意两点。

One is that the storage account is just for the unmanaged VM, to store the OS disk as a VHD file that you can manage it yourself. 一种是存储帐户仅用于非托管VM，用于将OS磁盘存储为VHD文件，您可以自己对其进行管理。 If you create a managed VM, the storage account is not needed to you. 如果创建托管VM，则不需要存储帐户。

Another is that the storage account also can store the logs, such as the diagnostic log. 另一个是存储帐户还可以存储日志，例如诊断日志。 If you do not want to store the logs, the storage account is also not needed to you. 如果您不想存储日志，则也不需要该存储帐户。

Note: If needed, you could just create one storage account to store the unmanaged VM OS disk and the logs as you want. 注意：如果需要，您可以只创建一个存储帐户来存储非托管VM OS磁盘和所需的日志。
