Azure 订阅和服务限制、配额和约束Azure subscription and service limits, quotas, and constraints

本文列出了一些最常见的 Microsoft Azure 限制,有时也称为配额。This document lists some of the most common Microsoft Azure limits, which are also sometimes called quotas. 本文当前并不涵盖所有 Azure 服务。This document doesn't currently cover all Azure services. 随着时间的推移,此列表将进行扩展和更新,以涵盖更多服务。Over time, the list will be expanded and updated to cover more services.

若要了解有关 Azure 定价的详细信息,请参阅azure 定价概述To learn more about Azure pricing, see Azure pricing overview. 在那里,可以使用定价计算器来估算成本。There, you can estimate your costs by using the pricing calculator. 你还可以转到特定服务的定价详细信息页,例如 Windows VMYou also can go to the pricing details page for a particular service, for example, Windows VMs. 有关帮助管理成本的提示,请参阅通过 Azure 计费和成本管理来防止意外成本For tips to help manage your costs, see Prevent unexpected costs with Azure billing and cost management.

备注

如果想要提高限制或配额,使其超出默认限制,可以免费建立联机客户支持请求If you want to raise the limit or quota above the default limit, open an online customer support request at no charge. 无法将限制提高到超过下表中显示的最大限制值。The limits can't be raised above the maximum limit value shown in the following tables. 如果没有最大限制列,则资源没有可调整的限制。If there's no maximum limit column, the resource doesn't have adjustable limits.

免费试用订阅不符合限制或配额增加的条件。Free Trial subscriptions aren't eligible for limit or quota increases. 如果有免费试用版订阅,可将其升级到即用即付订阅。If you have a Free Trial subscription, you can upgrade to a Pay-As-You-Go subscription. 有关详细信息,请参阅将Azure 免费试用版订阅升级到即用即付订阅免费试用订阅常见问题解答For more information, see Upgrade your Azure Free Trial subscription to a Pay-As-You-Go subscription and the Free Trial subscription FAQ.

限制和 Azure 资源管理器Limits and Azure Resource Manager

现在可以将多个 Azure 资源合并到单个 Azure 资源组中。It's now possible to combine multiple Azure resources into a single Azure resource group. 在使用资源组时,以前针对全局的限制会通过 Azure 资源管理器在区域级别进行管理。When you use resource groups, limits that once were global become managed at a regional level with Azure Resource Manager. 有关 Azure 资源组的详细信息,请参阅 Azure 资源管理器概述For more information about Azure resource groups, see Azure Resource Manager overview.

在下面的限制列表中,一个新表反映了在使用 Azure 资源管理器时的限制差异。In the following list of limits, a new table reflects any differences in limits when you use Azure Resource Manager. 例如,会存在一个“订阅限制”表和一个“订阅数限制 - Azure 资源管理器”表。For example, there's a Subscription limits table and a Subscription limits - Azure Resource Manager table. 如果某个限制同时适用于这两种方案,它会仅显示在第一个表中。When a limit applies to both scenarios, it's only shown in the first table. 除非另有说明,否则限制是跨所有区域的全局限制。Unless otherwise indicated, limits are global across all regions.

备注

Azure 资源组中的资源配额是用户的订阅可以访问的每个区域,而不像服务管理配额那样是可以访问的每个订阅。Quotas for resources in Azure resource groups are per-region accessible by your subscription, not per-subscription as the service management quotas are. 让我们以 vCPU 配额为例。Let's use vCPU quotas as an example. 若要请求提高 vCPU 支持数目的配额,必须确定要在哪些区域中使用多少 vCPU。To request a quota increase with support for vCPUs, you must decide how many vCPUs you want to use in which regions. 然后针对所需的 Azure 资源组 vCPU 配额的数量和区域发出特定请求。You then make a specific request for Azure resource group vCPU quotas for the amounts and regions that you want. 如果需要在西欧使用 30 个 vCPU 以在那里运行应用程序,则应专门在西欧请求 30 个 vCPU。If you need to use 30 vCPUs in West Europe to run your application there, you specifically request 30 vCPUs in West Europe. 这不会增加任何其他区域的 vCPU 配额 - 西欧的配额为 30 个 vCPU。Your vCPU quota isn't increased in any other region--only West Europe has the 30-vCPU quota.

因此,请考虑针对任意区域中的工作负荷来确定所需的 Azure 资源组配额,As a result, decide what your Azure resource group quotas must be for your workload in any one region. 然后在需将内容部署到其中的每个区域中请求相应的量。Then request that amount in each region into which you want to deploy. 若要了解如何确定特定区域的当前配额,请参阅排查部署问题For help in how to determine your current quotas for specific regions, see Troubleshoot deployment issues.

虚拟机磁盘限制Virtual machine disk limits

可以将多个数据磁盘附加到 Azure 虚拟机。You can attach a number of data disks to an Azure virtual machine. 根据 VM 数据磁盘的可伸缩性和性能目标, 可以确定需要满足性能和容量要求的磁盘数量和类型。Based on the scalability and performance targets for a VM's data disks, you can determine the number and type of disk that you need to meet your performance and capacity requirements.

重要

为了获得最佳性能,需要限制附加到虚拟机的、重度使用的磁盘数,以避免可能的性能限制。For optimal performance, limit the number of highly utilized disks attached to the virtual machine to avoid possible throttling. 如果所有附加的磁盘都没有同时使用, 则虚拟机可以支持更多的磁盘。If all attached disks aren't highly utilized at the same time, the virtual machine can support a larger number of disks.

  • 对于标准存储帐户: 标准存储帐户的总请求速率为 20000 IOPS。For Standard storage accounts: A Standard storage account has a maximum total request rate of 20,000 IOPS. 在标准存储帐户中, 所有虚拟机磁盘的 IOPS 总数不应超过此限制。The total IOPS across all of your virtual machine disks in a Standard storage account should not exceed this limit.

    根据请求速率限制, 你可以大致计算单个标准存储帐户支持的高利用率磁盘数。You can roughly calculate the number of highly utilized disks supported by a single Standard storage account based on the request rate limit. 例如, 对于基本层 VM, 利用率最高的磁盘数约为 66, 每个磁盘的 IOPS 为 20000/300。For example, for a Basic tier VM, the maximum number of highly utilized disks is about 66, which is 20,000/300 IOPS per disk. 标准层 VM 的利用率最高的磁盘数约为 40, 即每个磁盘 20000/500 IOPS。The maximum number of highly utilized disks for a Standard tier VM is about 40, which is 20,000/500 IOPS per disk.

  • 对于高级存储帐户: 高级存储帐户的总吞吐量速率为 50 Gbps。For Premium storage accounts: A Premium storage account has a maximum total throughput rate of 50 Gbps. 所有 VM 磁盘的总吞吐量不应超过此限制。The total throughput across all of your VM disks should not exceed this limit.

5存储限制是同一应用服务计划中所有应用的内容总大小。5The storage limit is the total content size across all apps in the same App service plan. 单个资源组和区域中所有应用服务计划的所有应用的总内容大小不能超过500GB。The total content size of all apps across all App service plans in a single resource group and region cannot exceed 500GB.
6这些资源受到专用实例上的物理资源(实例大小和实例数)的限制。6These resources are constrained by physical resources on the dedicated instances (the instance size and the number of instances).
7如果将基本层的某个应用扩展为两个实例,则其中每个实例有 350 个并发连接。7If you scale an app in the Basic tier to two instances, you have 350 concurrent connections for each of the two instances. 对于标准层和更高版本,web 套接字没有理论限制,但其他因素可能会限制 web 套接的数量。For Standard tier and above, there are no theoretical limits to web sockets, but other factors can limit the number of web sockets. 例如,允许的最大并发请求数(由 maxConcurrentRequestsPerCpu定义)为:每个小型 VM 7500、每个中型 VM 15000 (7500 x 2 核心)和75000(18750 x 4 核心)。For example, maximum concurrent requests allowed (defined by maxConcurrentRequestsPerCpu) are: 7,500 per small VM, 15,000 per medium VM (7,500 x 2 cores), and 75,000 per large VM (18,750 x 4 cores).
8最大 IP 连接数为每个实例,具体取决于实例大小:每 B1/S1/P1V2 实例的大小为 1920 3968,每个 B2/S2/P2V2 实例8064,每 B3/S3/P3V2 实例。8The maximum IP connections are per instance and depend on the instance size: 1,920 per B1/S1/P1V2 instance, 3,968 per B2/S2/P2V2 instance, 8,064 per B3/S3/P3V2 instance.
9可以通过支持请求将每个订阅的应用服务证书配额限制增加到最大限制为200。9The App Service Certificate quota limit per subscription can be increased via a support request to a maximum limit of 200.
10独立应用服务 Sku 可以通过 Azure 负载均衡器进行内部负载均衡(ILB),因此没有来自 internet 的公共连接。10App Service Isolated SKUs can be internally load balanced (ILB) with Azure Load Balancer, so there's no public connectivity from the internet. 因此,必须从能够直接访问 ILB 网络终结点的计算机使用 ILB 独立应用服务的某些功能。As a result, some features of an ILB Isolated App Service must be used from machines that have direct access to the ILB network endpoint.
11按需、按计划或作为应用服务实例内的后台任务连续运行自定义可执行文件和/或脚本。11Run custom executables and/or scripts on demand, on a schedule, or continuously as a background task within your App Service instance. 连续执行 WebJob 需要使用“始终打开”。Always On is required for continuous WebJobs execution. 计划的 WebJob 需要使用 Azure 计划程序免费或标准版。Azure Scheduler Free or Standard is required for scheduled WebJobs. 对于可以在应用服务实例中运行的 Webjob 的数量没有预定义的限制。There's no predefined limit on the number of WebJobs that can run in an App Service instance. 有实际的限制取决于应用程序代码尝试执行的操作。There are practical limits that depend on what the application code is trying to do.

Azure 认知搜索限制Azure Cognitive Search limits

定价层决定了搜索服务的容量和限制。Pricing tiers determine the capacity and limits of your search service. 层包括:Tiers include:

  • “免费”层为多租户服务,可与其他 Azure 订阅用户共享,仅用于评估和小型开发项目。Free multitenant service, shared with other Azure subscribers, is intended for evaluation and small development projects.
  • 基本层为规模较小的生产工作负荷提供专用计算资源,并为高可用查询工作负荷提供最多 3 个副本。Basic provides dedicated computing resources for production workloads at a smaller scale, with up to three replicas for highly available query workloads.
  • “标准”层(包括 S1、S2、S3 和 S3 高密度)适用于较大型生产工作负荷。Standard, which includes S1, S2, S3, and S3 High Density, is for larger production workloads. “标准”层内有多个级别,以便可以选择与工作负荷配置文件最匹配的资源配置。Multiple levels exist within the Standard tier so that you can choose a resource configuration that best matches your workload profile.

基于订阅的限制Limits per subscription

可以在一个订阅中创建多个服务。You can create multiple services within a subscription. 每一个服务都可以在特定层上进行预配。Each one can be provisioned at a specific tier. 你仅受每个层允许的服务数量限制。You're limited only by the number of services allowed at each tier. 例如,在同一订阅中,最多可以在基本层创建 12 个服务,在 S1 层也创建 12 个服务。For example, you could create up to 12 services at the Basic tier and another 12 services at the S1 tier within the same subscription. 有关层的详细信息,请参阅为 Azure 认知搜索选择 SKU 或层For more information about tiers, see Choose an SKU or tier for Azure Cognitive Search.

最大服务数限制可以根据请求提高。Maximum service limits can be raised upon request. 如果需要在同一订阅中使用更多服务,请与 Azure 支持部门联系。If you need more services within the same subscription, contact Azure Support.

1 免费层基于共享资源,而不基于专用资源。1 Free is based on shared, not dedicated, resources. 共享资源不支持纵向扩展。Scale-up is not supported on shared resources.

2 搜索单位是计费单位,以副本或分区形式分配。2 Search units are billing units, allocated as either a replica or a partition. 进行存储、索引和查询操作同时需要这两个资源。You need both resources for storage, indexing, and query operations. 若要了解有关 SU 计算的详细信息,请参阅缩放查询和索引工作负荷的资源级别To learn more about SU computations, see Scale resource levels for query and index workloads.

1 基本层有一个固定分区。1 Basic has one fixed partition. 在此层上,附加的搜索单元用于分配更多的副本以提高查询工作负荷。At this tier, additional search units are used for allocating more replicas for increased query workloads.

2 S3 HD 的硬性限制为3个分区,低于 S3 的分区限制。2 S3 HD has a hard limit of three partitions, which is lower than the partition limit for S3. 施加的分区限制较低是因为 S3 HD 的索引计数要高得多。The lower partition limit is imposed because the index count for S3 HD is substantially higher. 由于计算资源(存储和处理)和内容(索引和文档)都存在服务限制,因此会先达到内容限制。Given that service limits exist for both computing resources (storage and processing) and content (indexes and documents), the content limit is reached first.

3针对专用资源的计费服务提供服务级别协议。3 Service level agreements are offered for billable services on dedicated resources. 免费服务和预览功能没有 SLA。Free services and preview features have no SLA. 对于可计费服务,SLA 将在用户为服务预配足够冗余时生效。For billable services, SLAs take effect when you provision sufficient redundancy for your service. 查询(读取) Sla 需要两个或多个副本。Two or more replicas are required for query (read) SLAs. 查询和索引(读写) Sla 需要三个或更多的副本。Three or more replicas are required for query and indexing (read-write) SLAs. 分区数不是 SLA 注意事项。The number of partitions isn't an SLA consideration.

若要详细了解更详细的限制,例如文档大小、每秒查询数、密钥、请求和响应,请参阅Azure 认知搜索中的服务限制To learn more about limits on a more granular level, such as document size, queries per second, keys, requests, and responses, see Service limits in Azure Cognitive Search.

数据引入量速率Data ingestion volume rate

Azure Monitor 是一种大规模数据服务,每月为成千上万的客户发送数 TB 的数据,并且此数据仍在不断增长。Azure Monitor is a high scale data service that serves thousands of customers sending terabytes of data each month at a growing pace. 使用诊断设置从 Azure 资源发送的数据的默认引入量限制约为每个工作区6 GB/分钟The default ingestion volume rate limit for data sent from Azure resources using diagnostic settings is approximately 6 GB/min per workspace. 这是一个近似值,因为每个数据类型的实际大小都可以根据日志长度和其压缩率变化。This is an approximate value since the actual size can vary between data types depending on the log length and its compression ratio. 此限制不适用于从代理或数据收集器 API发送的数据。This limit does not apply to data that is sent from agents or Data Collector API.

如果以更高的速率将数据发送到单个工作区,则会删除某些数据,并且每隔6小时会将事件发送到工作区中的操作表,而阈值仍将会超出。If you send data at a higher rate to a single workspace, some data is dropped, and an event is sent to the Operation table in your workspace every 6 hours while the threshold continues to be exceeded. 如果引入卷继续超出速率限制,或者你预计会在某个时间到达,则可以通过打开支持请求来请求增加工作区。If your ingestion volume continues to exceed the rate limit or you are expecting to reach it sometime soon, you can request an increase to your workspace by opening a support request.

若要在工作区中收到此类事件的通知,请使用以下查询创建日志警报规则,并在结果大于数与零的情况下使用警报逻辑基数。To be notified on such an event in your workspace, create a log alert rule using the following query with alert logic base on number of results grater than zero.

  • 如果有16个以上的卷,则会在处理槽可用时按顺序处理它们。If there are more than 16 volumes, they're processed sequentially as processing slots become available.
  • 在操作完成之前,无法执行克隆或还原的分层卷的新备份。New backups of a cloned or a restored tiered volume can't occur until the operation is finished. 对于本地卷,卷处于联机状态后允许进行备份。For a local volume, backups are allowed after the volume is online.
分层卷的还原和克隆恢复时间Restore and clone recover time for tiered volumes < 2 分钟<2 minutes
  • 卷在还原或克隆操作的2分钟内可用,而不考虑卷大小。The volume is made available within 2 minutes of a restore or clone operation, regardless of the volume size.
  • 由于大部分数据和元数据仍驻留在云中,因此卷性能可能比正常情况慢。The volume performance might initially be slower than normal as most of the data and metadata still resides in the cloud. 随着数据从云流向 StorSimple 设备,性能可能会增加。Performance might increase as data flows from the cloud to the StorSimple device.
  • 下载元数据的总时间取决于分配的卷大小。The total time to download metadata depends on the allocated volume size. 在后台,元数据会自动以 5 分钟 1 TB 已分配卷数据的速率载入设备中。Metadata is automatically brought into the device in the background at the rate of 5 minutes per TB of allocated volume data. 此速率可能受到云的 Internet 带宽的影响。This rate might be affected by Internet bandwidth to the cloud.
  • 当所有元数据都位于设备上时,还原或克隆操作即告完成。The restore or clone operation is complete when all the metadata is on the device.
  • 在还原或克隆操作完全完成之前,无法执行备份操作。Backup operations can't be performed until the restore or clone operation is fully complete.

  • 与分层卷不同,如果存在本地固定卷,则卷数据也会下载到本地设备上。Unlike tiered volumes, if there are locally pinned volumes, the volume data is also downloaded locally on the device. 将所有卷数据下载到设备后,还原操作即告完成。The restore operation is complete when all the volume data has been brought to the device.
  • 还原操作可能很长,完成还原的总时间取决于预配的本地卷的大小、Internet 带宽和设备上的现有数据。The restore operations might be long and the total time to complete the restore will depend on the size of the provisioned local volume, your Internet bandwidth, and the existing data on the device. 在还原操作过程中,允许在本地固定卷上进行备份操作。Backup operations on the locally pinned volume are allowed while the restore operation is in progress.

备注

在上表中,我们发现,对于 RSA 2048 位软件密钥,允许2000每10秒获取事务数。In the previous table, we see that for RSA 2,048-bit software keys, 2,000 GET transactions per 10 seconds are allowed. 对于 RSA 2048 位 HSM-密钥,允许1000每10秒获取事务数。For RSA 2,048-bit HSM-keys, 1,000 GET transactions per 10 seconds are allowed.

限制阈值为加权,并强制执行。The throttling thresholds are weighted, and enforcement is on their sum. 例如,如上表所示,在 RSA HSM 密钥上执行 GET 操作时,使用4096位密钥比2048位密钥的8倍。For example, as shown in the previous table, when you perform GET operations on RSA HSM-keys, it's eight times more expensive to use 4,096-bit keys compared to 2,048-bit keys. 这是因为 1000/125 = 8。That's because 1,000/125 = 8.

在给定的10秒的时间间隔内,Azure Key Vault 客户端在遇到429限制 HTTP 状态代码之前只能执行以下操作之一:In a given 10-second interval, an Azure Key Vault client can do only one of the following operations before it encounters a 429 throttling HTTP status code:

  • 2000 RSA 2048 位软件-密钥获取事务2,000 RSA 2,048-bit software-key GET transactions
  • 1000 RSA 2048-位 HSM-密钥获取事务1,000 RSA 2,048-bit HSM-key GET transactions
  • 125 RSA 4096-位 HSM-密钥获取事务125 RSA 4,096-bit HSM-key GET transactions
