Azure 訂用帳戶和服務限制、配額與限制Azure subscription and service limits, quotas, and constraints
本文件列出一些最常見的 Microsoft Azure 限制,有時也稱為配額。This document lists some of the most common Microsoft Azure limits, which are also sometimes called quotas.
若要深入瞭解 Azure 定價,請參閱 azure 定價總覽。To learn more about Azure pricing, see Azure pricing overview. 您可以在這裡使用 定價計算機來預估成本。There, you can estimate your costs by using the pricing calculator. 您也可以移至特定服務的定價詳細資料頁面,例如 Windows vm。You also can go to the pricing details page for a particular service, for example, Windows VMs. 如需協助您管理成本的祕訣,請參閱使用 Azure 計費與成本管理避免非預期的成本。For tips to help manage your costs, see Prevent unexpected costs with Azure billing and cost management.
管理限制Managing limits
注意
某些服務具有可調整的限制。Some services have adjustable limits.
當服務沒有可調整的限制時,下表會使用標頭 限制。When a service doesn't have adjustable limits, the following tables use the header Limit. 在這些情況下,預設和最大限制是相同的。In those cases, the default and the maximum limits are the same.
當限制可以調整時,資料表會包含 預設限制 和 最大限制 標頭。When the limit can be adjusted, the tables include Default limit and Maximum limit headers. 限制可以在預設限制以上引發,但不能超過上限。The limit can be raised above the default limit but not above the maximum limit.
如果您想要將限制或配額提高到超過預設限制,請免費 開啟線上客戶支援要求。If you want to raise the limit or quota above the default limit, open an online customer support request at no charge.
「 軟 限制」和「 固定限制 」通常會用非正式方式來描述目前的可調整限制, (軟限制) ,而最大限制 () 的固定限制。The terms soft limit and hard limit often are used informally to describe the current, adjustable limit (soft limit) and the maximum limit (hard limit). 如果無法調整限制,就不會有軟限制,只有硬性限制。If a limit isn't adjustable, there won't be a soft limit, only a hard limit.
免費試用版 訂用帳戶不符合限制或配額增加的資格。Free Trial subscriptions aren't eligible for limit or quota increases. 如果您有免費試用訂用帳戶,則可以升級到隨用隨付訂用帳戶。If you have a Free Trial subscription, you can upgrade to a Pay-As-You-Go subscription. 如需詳細資訊,請參閱將 您的 Azure 免費試用版訂用帳戶升級為隨用隨付訂 用帳戶和 免費試用訂用帳戶常見問題。For more information, see Upgrade your Azure Free Trial subscription to a Pay-As-You-Go subscription and the Free Trial subscription FAQ.
某些限制是在區域層級進行管理。Some limits are managed at a regional level.
讓我們以 vCPU 配額為例。Let's use vCPU quotas as an example. 若要使用個 vcpu 的支援要求增加配額,您必須決定要在哪些區域中使用多少個 vcpu。To request a quota increase with support for vCPUs, you must decide how many vCPUs you want to use in which regions. 然後,針對您想要的數量和區域,對 Azure 資源群組 vCPU 配額的特定要求。You then make a specific request for Azure resource group vCPU quotas for the amounts and regions that you want. 如果您需要在西歐使用30個個 vcpu 來執行您的應用程式,您必須特別在西歐要求30個 vcpu。If you need to use 30 vCPUs in West Europe to run your application there, you specifically request 30 vCPUs in West Europe. 您的 vCPU 配額不會增加到任何其他區域,只有西歐具有 30 vCPU 配額。Your vCPU quota isn't increased in any other region--only West Europe has the 30-vCPU quota.
因此,在任何一個區域中,決定您的工作負載所需的 Azure 資源群組配額。As a result, decide what your Azure resource group quotas must be for your workload in any one region. 然後在您要部署的每個區域中要求該數量。Then request that amount in each region into which you want to deploy. 如需如何判斷特定區域目前配額的協助,請參閱 解決資源配額的錯誤。For help in how to determine your current quotas for specific regions, see Resolve errors for resource quotas.

1應用程式和儲存體配額是依每個 App Service 方案為準,除非另有指示。1Apps and storage quotas are per App Service plan unless noted otherwise.
2您可以在這些電腦上裝載的實際應用程式數目,會視應用程式的活動、電腦執行個體的大小,及對應的資源使用率而定。2The actual number of apps that you can host on these machines depends on the activity of the apps, the size of the machine instances, and the corresponding resource utilization.
3專用的執行個體可有不同的大小。3Dedicated instances can be of different sizes. 如需詳細資訊,請參閱 App Service 價格。For more information, see App Service pricing.
4可應要求提高數量。4More are allowed upon request.
5儲存體限制是跨相同 App Service 方案中所有應用程式的目前總大小。5The storage limit is the total content size across all apps in the same App service plan. 單一資源群組和區域中所有 App Service 方案上的所有應用程式內容大小總計不能超過 500GB。The total content size of all apps across all App service plans in a single resource group and region cannot exceed 500GB.
6這些資源都會受到專用執行個體 (執行個體大小和執行個體數目) 上的實體資源限制。6These resources are constrained by physical resources on the dedicated instances (the instance size and the number of instances).
7如果您將基本層的一個應用程式調整為兩個執行個體,則其中每個執行個體有 350 個並行連線。7If you scale an app in the Basic tier to two instances, you have 350 concurrent connections for each of the two instances. 針對標準層和其以上版本,Web 通訊端沒有理論上的限制,但其他因素可能會限制 Web 通訊端的數目。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,允許的並行要求數上限 (由 maxConcurrentRequestsPerCpu
所定義) 是:每個小型 VM 7,500 個、每個中型 VM 15,000 個 (7,500 x 2 個核心) 和每個大型 VM 75,000 個 (18,750 x 4 個核心)。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).
8IP 連線數會以執行個體為基礎,並且取決於執行個體的大小:每個 B1/S1/P1V3 執行個體 1,920 個、每個 B2/S2/P2V3 執行個體3,968 個、每個 B3/S3/P3V3 執行個體 8,064 個。8The maximum IP connections are per instance and depend on the instance size: 1,920 per B1/S1/P1V3 instance, 3,968 per B2/S2/P2V3 instance, 8,064 per B3/S3/P3V3 instance.
9您可以透過支援要求將每個訂用帳戶的 App Service 憑證配額限制增加到最多 200 個。9The App Service Certificate quota limit per subscription can be increased via a support request to a maximum limit of 200.
10App Service 隔離式 SKU 能夠透過 Azure Load Balancer 在內部達成負載平衡 (ILB),因此網際網路未提供公用連線。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,ILB 隔離式 App Service 的某些功能必須從具有 ILB 網路端點直接存取權的電腦才能使用。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在您的 App Service 執行個體中,以背景工作的方式隨選、依照排程或連續執行自訂可執行檔和/或指令碼。11Run custom executables and/or scripts on demand, on a schedule, or continuously as a background task within your App Service instance. 若要連續執行 WebJobs,「永遠開啟」是必要選項。Always On is required for continuous WebJobs execution. 可在 App Service 執行個體中執行的 WebJobs 數目沒有預先定義的限制。There's no predefined limit on the number of WebJobs that can run in an App Service instance. 但根據應用程式程式碼嘗試執行的動作,會有一些實際限制。There are practical limits that depend on what the application code is trying to do.
12不支援裸網域。12Naked domains are not supported. 只發出標準憑證 (無法使用萬用字元憑證)。Only issuing standard certificates (wildcard certificates are not available). 限制為每個自訂網域只能有一個免費憑證。Limited to only one free certificate per custom domain.

View Designer 不支援跨資源查詢。Cross-resource query is not supported in View Designer. 新的 scheduledQueryRules API 支援記錄警示中的跨資源查詢。Cross-resource query in log alerts is supported in the new scheduledQueryRules API. 如需詳細資訊,請參閱跨資源查詢限制。See Cross-resource query limits for details. |
使用者查詢節流User query throttling
Azure 監視器有數個節流限制,可防止使用者傳送過多的查詢。Azure Monitor has several throttling limits to protect against users sending an excessive number of queries. 這類行為可能會導致系統後端資源多載,並損害服務回應能力。Such behavior can potentially overload the system backend resources and jeopardize service responsiveness. 下列限制旨在保護客戶避免遇到業務中斷,並確保一致的服務層級。The following limits are designed to protect customers from interruptions and ensure consistent service level. 使用者節流和限制旨在影響極端使用案例,並且與一般使用方式無關。The user throttling and limits are designed to impact only extreme usage scenario and should not be relevant for typical usage.
MeasureMeasure | 每位使用者限制Limit per user | 描述Description |
---|---|---|
並行查詢Concurrent queries | 55 | 如果該使用者已有 5 個查詢正在執行,則會將所有新查詢放在每個使用者的並行佇列中。If there are already 5 queries running for the user, any new queries are placed in a per-user concurrency queue. 當其中一個正在執行的查詢結束時,會從佇列中提取下一個查詢並啟動。When one of the running queries ends, the next query will be pulled from the queue and started. 這不包含來自警示規則的查詢。This does not include queries from alert rules. |
並行佇列中的時間Time in concurrency queue | 3 分鐘3 minutes | 如果查詢停留在佇列中的時間超過3分鐘而未啟動,則會以錯誤碼 429 的 HTTP 錯誤回應終止。If a query sits in the queue for more than 3 minutes without being started, it will be terminated with an HTTP error response with code 429. |
並行佇列中的查詢總數Total queries in concurrency queue | 200200 | 一旦佇列中的查詢數目達到 200,任何其他查詢都會以 HTTP 錯誤碼 429 拒絕。Once the number of queries in the queue reaches 200, any additional queries will by rejected with an HTTP error code 429. 此數目是除了可同時執行的 5 個查詢以外的數目。This number is in addition to the 5 queries that can be running simultaneously. |
查詢速率Query rate | 每 30 秒 200 個查詢200 queries per 30 seconds | 這是單一使用者可以向所有工作區提交查詢的整體速率。This is the overall rate that queries can be submitted by a single user to all workspaces. 這項限制適用於程式設計查詢或由視覺效果組件 (例如 Azure 儀表板和 Log Analytics 工作區摘要頁面) 所起始的查詢。This limit applies to programmatic queries or queries initiated by visualization parts such as Azure dashboards and the Log Analytics workspace summary page. |
- 如在 Azure 監視器中最佳化記錄查詢中所述,將查詢最佳化。Optimize your queries as described in Optimize log queries in Azure Monitor.
- 儀表板和活頁簿可以在單一檢視中包含多個查詢,其會在每次載入或重新整理時產生高載查詢。Dashboards and workbooks can contain multiple queries in a single view that generate a burst of queries every time they load or refresh. 請考慮將這些查詢拆分為視需要載入的多個檢視。Consider breaking them up into multiple views that load on demand.
- 在 Power BI 中,請考慮僅擷取匯總的結果,而不是原始記錄。In Power BI, consider extracting only aggregated results rather than raw logs.

資料擷取磁碟區速率Data ingestion volume rate
Azure 監視器是一種大規模的資料服務,服務對象為每月需傳送數 TB 資料 (且不斷成長) 的上千名客戶。Azure Monitor is a high scale data service that serves thousands of customers sending terabytes of data each month at a growing pace. 磁碟區速率限制旨在將 Azure 監視器客戶隔離,避免其受到多租用戶環境中突然激增的尖峰所影響。The volume rate limit intends to isolate Azure Monitor customers from sudden ingestion spikes in multitenancy environment. 定義於工作區的預設擷取磁碟區速率閾值為 500 MB (已壓縮),解壓縮大約 6 GB/分鐘 -- 根據記錄長度和其壓縮率的不同,實際大小在資料類型之間可能會有所不同。A default ingestion volume rate threshold of 500 MB (compressed) is defined in workspaces, this is translated to approximately 6 GB/min uncompressed -- the actual size can vary between data types depending on the log length and its compression ratio. 磁碟區速率限制適用於透過 診斷設定 從 Azure 資源內嵌的資料。The volume rate limit applies to data ingested from Azure resources via Diagnostic settings. 達到磁碟區速率限制時,重試機制會嘗試在 30 分鐘內內嵌資料 4 次,並在作業失敗後將其卸載。When volume rate limit is reached, a retry mechanism attempts to ingest the data 4 times in a period of 30 minutes and drop it if operation fails. 其不適用於從 代理程式 或 資料收集器 API 中內嵌的資料。It doesn't apply to data ingested from agents or Data Collector API.
如果以高於工作區中所設定閾值的 80% 速率將資料傳送至您的工作區時,則每隔 6 小時會將事件傳送至工作區中的 [作業] 資料表,同時會持續超過閾值。When data sent to your workspace is at a volume rate higher than 80% of the threshold configured in your workspace, an event is sent to the Operation table in your workspace every 6 hours while the threshold continues to be exceeded. 當內嵌的磁碟區速率高於閾值時,則系統會卸除某些資料,且每隔 6 小時會將事件傳送至工作區中的 [作業] 資料表,同時會持續超過閾值。When ingested volume rate is higher than threshold, 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. 如果您的擷取磁碟區速率持續超過閾值,或您希望很快能達到某個閾值,則可以透過開啟支援要求,要求增加速率。If your ingestion volume rate continues to exceed the threshold or you are expecting to reach it sometime soon, you can request to increase it in by opening a support request.
請參閱在 Azure 監視器中監視 Log Analytics 工作區的健康情況,以建立要在您達到任何擷取限制時主動發出通知的警示規則。See Monitor health of Log Analytics workspace in Azure Monitor to create alert rules to be proactively notified when you reach any ingestion limits.

重要
為了協助我們更有效地管理全球流感期間的產能,某些區域中新 Batch 帳戶的預設核心配額,以及某些類型的訂用帳戶,在某些情況下會從上述值範圍中縮減為零個核心。To help us better manage capacity during the global health pandemic, the default core quotas for new Batch accounts in some regions and for some types of subscription have been reduced from the above range of values, in some cases to zero cores. 當您建立新的 Batch 帳戶時,檢查您的核心配額 並視需要要求增加的核心配額。When you create a new Batch account, check your core quota and request a core quota increase, if required. 或者,考慮重新使用已具有足夠配額的 Batch 帳戶。Alternatively, consider reusing Batch accounts that already have sufficient quota.

注意
在上表中,我們看到 RSA 2,048 位元軟體金鑰,每 10 秒允許的 2,000 個 GET 交易。In the previous table, we see that for RSA 2,048-bit software keys, 2,000 GET transactions per 10 seconds are allowed. 對於 RSA 2,048 位元 HSM 金鑰,每 10 秒允許 1,000 個 GET 交易。For RSA 2,048-bit HSM-keys, 1,000 GET transactions per 10 seconds are allowed.
節流閾值會進行加權,並依其總和強制執行。The throttling thresholds are weighted, and enforcement is on their sum. 例如,如上表所示,當您在 RSA HSM 金鑰上執行 GET 作業時,使用 4,096 位元金鑰比起使用 2,048 位元金鑰貴八倍。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. 這是因為 1,000/125 = 8。That's because 1,000/125 = 8.
在指定的 10 秒間隔內,Azure Key Vault 用戶端在遇到 429

每個受控識別都會計入 Azure AD 租用戶中的物件配額限制,如 Azure AD 服務限制中所述。Each managed identity counts towards the object quota limit in an Azure AD tenant as described in Azure AD service limits and restrictions.
可建立受控識別的速率有下列限制:The rate at which managed identities can be created have the following limits:
- 每個 Azure 區域的每個 Azure AD 租用戶:每 20 秒 200 個建立作業。Per Azure AD Tenant per Azure region: 200 create operations per 20 seconds.
- 每個 Azure 區域的每個 Azure 訂用帳戶:每 20 秒 40 個建立作業。Per Azure Subscription per Azure region : 40 create operations per 20 seconds.
在您建立使用者指派的受控身分識別時,僅支援使用英數字元 (0-9、a-z 和 A-Z) 和連字號 (-)。When you create user-assigned managed identities, only alphanumeric characters (0-9, a-z, and A-Z) and the hyphen (-) are supported. 若要讓指派至虛擬機器或虛擬機器擴展集正常運作,名稱限制為 24 個字元。For the assignment to a virtual machine or virtual machine scale set to work properly, the name is limited to 24 characters.

逾時值Timeout values
用戶端至 Front DoorClient to Front Door
- Front Door 的閒置 TCP 連線逾時為 61 秒。Front Door has an idle TCP connection timeout of 61 seconds.
Front Door 至應用程式後端Front Door to application back-end
- 如果回應是區塊式回應,則若在收到第一個區塊時會傳回 200。If the response is a chunked response, a 200 is returned if or when the first chunk is received.
- 將 HTTP 要求轉送至後端之後,Front Door 會對後端的第一個封包等待 30 秒。After the HTTP request is forwarded to the back end, Front Door waits for 30 seconds for the first packet from the back end. 然後會將 503 錯誤傳回給用戶端。Then it returns a 503 error to the client. 此值可以透過 API 中的 sendRecvTimeoutSeconds 欄位來設定。This value is configurable via the field sendRecvTimeoutSeconds in the API.
- 針對快取案例,此逾時無法設定,因此如果快取要求,而且來自 Front Door 或後端的第一個封包耗時超過 30 秒,則會將 504 錯誤傳回給用戶端。For caching scenarios, this timeout is not configurable and so, if a request is cached and it takes more than 30 seconds for the first packet from Front Door or from the backend, then a 504 error is returned to the client.
- 後端收到第一個封包後,Front Door 會等候 30 秒 (閒置逾時)。After the first packet is received from the back end, Front Door waits for 30 seconds in an idle timeout. 然後會將 503 錯誤傳回給用戶端。Then it returns a 503 error to the client. 此逾時值無法設定。This timeout value is not configurable.
- Front Door 至後端 TCP 工作階段的逾時為 90 秒鐘。Front Door to the back-end TCP session timeout is 90 seconds.

虛擬機器磁碟限制Virtual machine disk limits
您可以將一些資料磁碟連結至 Azure 虛擬機器。You can attach a number of data disks to an Azure virtual machine. 根據 VM 資料磁碟的可擴縮性和效能目標,您可以決定您需要的磁碟數目和類型,以符合您的效能和容量需求。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
為達最佳效能,限制連結至虛擬機器的高度使用磁碟數目,以避免可能的節流。For optimal performance, limit the number of highly utilized disks attached to the virtual machine to avoid possible throttling. 如果所有連結的磁碟並未同時高度使用,則虛擬機器可支援更多磁碟。If all attached disks aren't highly utilized at the same time, the virtual machine can support a larger number of disks.
針對 Azure 受控磁碟:For Azure managed disks:
下表說明每個訂用帳戶每個區域的預設資源數和資源數上限。The following table illustrates the default and maximum limits of the number of resources per region per subscription. 無論磁碟以平台代控金鑰還是客戶自控金鑰進行加密,限制都會維持不變。The limits remain the same irrespective of disks encrypted with either platform-managed keys or customer-managed keys. 每個資源群組的受控磁碟、快照集和映像數目沒有限制。There is no limit for the number of Managed Disks, snapshots and images per resource group.

若為標準儲存體帳戶: 標準儲存體帳戶的總要求率上限為 20000 IOPS。For Standard storage accounts: A Standard storage account has a maximum total request rate of 20,000 IOPS. 在標準儲存體帳戶中,所有虛擬機器磁碟的 IOPS 總數不得超過此限。The total IOPS across all of your virtual machine disks in a Standard storage account should not exceed this limit.
您可以根據要求率的限制,大致計算單一標準儲存體帳戶可支援的高度使用磁碟數目。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,針對基本層 VM,高度使用的磁碟數目上限約為 66 (每一磁碟 20,000/300 IOPS)。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. 標準層 VM 的高度使用的磁碟數目上限約為 40 (每一磁碟 20,000/500 IOPS)。The maximum number of highly utilized disks for a Standard tier VM is about 40, which is 20,000/500 IOPS per disk.
若為進階儲存體帳戶: 進階儲存體帳戶的總輸送量速率上限為 50 Gbps。For Premium storage accounts: A Premium storage account has a maximum total throughput rate of 50 Gbps. 所有 VM 磁碟的總輸送量不應該超過此限。The total throughput across all of your VM disks should not exceed this limit.
如需詳細資訊,請參閱 虛擬機器大小。For more information, see Virtual machine sizes.
磁片加密集Disk encryption sets
每個訂用帳戶的每個區域都有50磁片加密集的限制。There's a limitation of 50 disk encryption sets per region, per subscription. 如需詳細資訊,請參閱適用于 Linux 或 Windows 虛擬機器的加密檔。For more information, see the encryption documentation for Linux or Windows virtual machines. 如果您需要增加配額,請聯絡 Azure 支援。If you need to increase the quota, contact Azure support.

1 使用傳統部署模型 (而非 Azure Resource Manager) 所建立的虛擬機器都會自動儲存在雲端服務中。1 Virtual machines created by using the classic deployment model instead of Azure Resource Manager are automatically stored in a cloud service. 您可以將更多虛擬機器加入至該雲端服務以獲得負載平衡和可用性。You can add more virtual machines to that cloud service for load balancing and availability.
2 輸入端點即可從虛擬機器的雲端服務外部與某個虛擬機器進行通訊。2 Input endpoints allow communications to a virtual machine from outside the virtual machine's cloud service. 在相同雲端服務或虛擬網路中的虛擬機器可自動彼此通訊。Virtual machines in the same cloud service or virtual network can automatically communicate with each other.
虛擬機器限制 - Azure 資源管理員Virtual Machines limits - Azure Resource Manager
當您使用 Azure Resource Manager 和 Azure 資源群組時,適用下列限制。The following limits apply when you use Azure Resource Manager and Azure resource groups.
資源Resource | 限制Limit |
---|---|
每一訂用帳戶 VMVMs per subscription | 每個區域 25,000 個1。25,0001 per region. |
每一訂用帳戶的 VM 總計核心VM total cores per subscription | 每個區域 20 個1。201 per region. 請連絡支援人員以提高限制。Contact support to increase limit. |
每一訂用帳戶的 Azure 現成 VM 總核心Azure Spot VM total cores per subscription | 每個區域 20 個1。201 per region. 請連絡支援人員以提高限制。Contact support to increase limit. |
每一訂用帳戶的每個系列 (例如 Dv2 和 F) VM 核心VM per series, such as Dv2 and F, cores per subscription | 每個區域 20 個1。201 per region. 請連絡支援人員以提高限制。Contact support to increase limit. |
每一訂用帳戶的可用性設定組Availability sets per subscription | 每個區域 2,500 個。2,500 per region. |
每一可用性設定組的虛擬機器Virtual machines per availability set | 200200 |
依資源群組的鄰近放置群組Proximity placement groups per resource group | 800800 |
每一可用性設定組的虛擬機器Certificates per availability set | 19921992 |
每一訂用帳戶的憑證Certificates per subscription | 無限制3Unlimited3 |
1預設限制會因供應項目類別類型 (例如免費試用版和隨用隨付) 以及因系列 (例如 Dv2、F 和 G) 而有所不同。例如,Enterprise 合約訂用帳戶的預設值為 350。1 Default limits vary by offer category type, such as Free Trial and Pay-As-You-Go, and by series, such as Dv2, F, and G. For example, the default for Enterprise Agreement subscriptions is 350.
2屬性 (例如 SSH 公開金鑰) 也會推送為憑證,並計入此限制。2 Properties such as SSH public keys are also pushed as certificates and count towards this limit. 若要略過此限制,請使用適用於 Windows 的 Azure Key Vault 延伸模組,或適用於 Linux 的 Azure Key Vault 延伸模組以安裝憑證。To bypass this limit, use the Azure Key Vault extension for Windows or the Azure Key Vault extension for Linux to install certificates.
3使用 Azure 資源管理員時,憑證會儲存在 Azure 金鑰保存庫內。3 With Azure Resource Manager, certificates are stored in the Azure Key Vault. 訂用帳戶的憑證數目不受限制。The number of certificates is unlimited for a subscription. 每一部署都有 1 MB 的憑證限制,這是由單一 VM 或可用性設定組所組成。There's a 1-MB limit of certificates per deployment, which consists of either a single VM or an availability set.
注意
虛擬機器核心具有區域總限制。Virtual machine cores have a regional total limit. 其也有每一大小系列 (例如 Dv2 和 F) 的區域性限制。系統會分別強制執行這些限制。They also have a limit for regional per-size series, such as Dv2 and F. These limits are separately enforced. 例如,請考慮美國東部訂用帳戶的總計 VM 核心限制為 30、A 系列核心限制為 30,和 D 系列核心限制為 30。For example, consider a subscription with a US East total VM core limit of 30, an A series core limit of 30, and a D series core limit of 30. 此訂用帳戶可以部署 30 個 A1 VM、30 個 D1 VM,或是兩個的組合,總計不超過 30 個核心。This subscription can deploy 30 A1 VMs, or 30 D1 VMs, or a combination of the two not to exceed a total of 30 cores. 組合的範例為 10 個 A1 VM 和 20 個 D1 VM。An example of a combination is 10 A1 VMs and 20 D1 VMs.
共用映射庫限制Shared Image Gallery limits
使用共用映射庫部署資源時,每個訂用帳戶都有限制:There are limits, per subscription, for deploying resources using Shared Image Galleries:
- 每個區域中每個訂用帳戶 100 個共用映像庫100 shared image galleries, per subscription, per region
- 每個區域中每個訂用帳戶 1000 個映像定義1,000 image definitions, per subscription, per region
- 每個區域中每個訂用帳戶 10000 個映像版本10,000 image versions, per subscription, per region
