Azure VM 存储是Azure云平台上的一种服务,它提供了可靠、高性能、可扩展的云端存储服务,可以用来存储Azure虚拟机(VM)的磁盘卷、数据文件和操作系统。
Azure VM 存储基于高度可扩展的Blob和存储盘技术构建,使用多种存储类型,包括标准和高级磁盘、文件和存储帐户等,实现了数据的高可用、持久性和可靠性等功能。
Azure VM 存储具有以下主要功能:
支持多种存储类型:Azure VM 存储包括标准存储、高级存储和文件存储等多种类型,可根据应用场景和性能需求选择合适的存储类型,实现最佳性能和成本效益的平衡。
提供高级功能:Azure VM 存储提供多种高级功能,如快照、自动副本和冷存储等,可帮助用户轻松地保护和管理其数据。
确保高度可用和可靠性:Azure VM 存储能够灵活地扩展和管理数据,支持跨多个区域的复制和备份,确保数据的高度可用和可靠性。
提高性能和吞吐量:Azure VM 存储拥有出色的性能和吞吐量,可以为高负载工作负载提供快速的响应,并提供了多种选项来优化性能。
在使用 Azure VM 存储时,可以遵循以下步骤:
创建存储帐户:在Azure门户中创建存储帐户,选择合适的存储类型和性能层,为Azure VM 存储分配所需的容量和可用区域。
创建虚拟机:在Azure门户中创建虚拟机,选择合适的映像和配置,为虚拟机分配所需的磁盘大小和类型。
将存储帐户附加到虚拟机:在虚拟机设置中选择存储帐户,将其附加到虚拟机中,以便虚拟机可以使用 Azure VM 存储来存储其磁盘和数据文件。
管理存储数据:使用Azure VM 存储的管理工具和API,对存储的数据进行管理,包括上传、下载、备份、恢复、删除等操作。
以下是使用Azure VM存储的Python代码示例,包括创建存储帐户、创建虚拟机、附加存储帐户和管理存储数据等操作:
# 导入Azure SDK
from azure.mgmt.compute import ComputeManagementClient
from azure.mgmt.storage import StorageManagementClient
from azure.identity import DefaultAzureCredential
# 创建 Azure 存储帐户
def create_storage_account(storage_client, resource_group_name, storage_account_name, location):
storage_async_operation = storage_client.storage_accounts.create(
resource_group_name=resource_group_name,
account_name=storage_account_name,
sku={'name': 'Standard_LRS'},
kind='StorageV2',
location=location
)
storage_account = storage_async_operation.result()
print("Azure Storage account '{}' is created.".format(storage_account.name))
# 创建 Azure 虚拟机

# 创建虚拟机

)

# 将 Azure 存储帐户附加到虚拟机
def attach_storage_account_to_virtual_machine(compute_client, resource_group_name, vm_name, storage_account_name):

disk_uri = "/subscriptions/<subscription_id>/resourceGroups/<resource_group_name>/providers/Microsoft.Storage/storageAccounts/{}/dataDisks/{}-datadisk".format(storage_account_name, vm_name)
vm.storage_profile.data_disks.append({
"lun": 0,
"name": vm_name + "-datadisk",
"create_option": "Attach",
"managed_disk": {
"id": disk_uri
}
})
async_vm_update = compute_client.virtual_machines.create_or_update(
resource_group_name=resource_group_name,
vm_name=vm_name,
parameters=vm)
async_vm_update.wait()
print("Storage account '{}' attached to virtual machine '{}'.".format(storage_account_name, vm_name))
# 使用 Azure 存储帐户管理数据
def manage_storage_data(storage_client, resource_group_name, storage_account_name):
# 上传文件到 Blob 存储
blob_service = storage_client.blob_services.get(resource_group_name, storage_account_name)
container_name = "mycontainer"
blob_name = "myblob.txt"
content = "This is my blob content."
blob_service.create_container(container_name)
blob_service.create_block_blob_from_text(container_name, blob_name, content)
# 下载文件
download_blob = blob_service.get_blob_to_text(container_name, blob_name)
print("Blob content: '{}'".format(download_blob.content))
# 鉴权并创建 Azure 客户端
credential = DefaultAzureCredential()
compute_client = ComputeManagementClient(
credential=credential,
subscription_id="<subscription_id>",
base_url=None
)
storage_client = StorageManagementClient(
credential=credential,
subscription_id="<subscription_id>",
base_url=None
)
# 创建存储帐户、虚拟机,并将存储帐户附加到虚拟机
resource_group_name = "myresourcegroup"
location = "eastus"
vm_name = "myvm"
storage_account_name = "mystorageaccount"
create_storage_account(storage_client, resource_group_name, storage_account_name, location)
create_virtual_machine(compute_client, resource_group_name, location, vm_name, storage_account_name)
attach_storage_account_to_virtual_machine(compute_client, resource_group_name, vm_name, storage_account_name)
# 使用存储帐户管理数据
manage_storage_data(storage_client, resource_group_name, storage_account_name)
代码示例中使用到了Azure SDK中的Azure 存储帐户和计算服务管理客户端,通过代码进行虚拟机的创建、存储帐户的附加和数据的上传和下载等操作。具体代码实现可以根据实际需求进行修改和优化。
