Microsoft Azure Subscription and Service Limits, Quotas, and Constraints
Provides a list of common Azure subscription and service limits, quotas, and constraints. This includes information on how to increase limits along with maximum values.

Azure subscription and service limits, quotas, and constraints

This document lists some of the most common Microsoft Azure limits, which are also sometimes called quotas. This document doesn't currently cover all Azure services. Over time, the list will be expanded and updated to cover more of the platform.

Please visit Azure Pricing Overview to learn more about Azure pricing. There, you can estimate your costs using the Pricing Calculator or by visiting the pricing details page for a service (for example, Windows VMs).

[!NOTE] If you want to raise the limit or quota above the Default Limit, open an online customer support request at no charge. The limits can't be raised above the Maximum Limit value shown in the following tables. If there is no Maximum Limit column, then the resource doesn't have adjustable limits.

Free Trial subscriptions are not eligible for limit or quota increases. If you have a Free Trial, you can upgrade to a Pay-As-You-Go subscription. For more information, see Upgrade Azure Free Trial to Pay-As-You-Go.

Limits and the Azure Resource Manager

It is now possible to combine multiple Azure resources in to a single Azure Resource Group. When using Resource Groups, limits that once were global become managed at a regional level with the Azure Resource Manager. For more information about Azure Resource Groups, see Azure Resource Manager overview.

In the limits below, a new table has been added to reflect any differences in limits when using the Azure Resource Manager. For example, there is a Subscription Limits table and a Subscription Limits - Azure Resource Manager table. When a limit applies to both scenarios, it is only shown in the first table. Unless otherwise indicated, limits are global across all regions.

[!NOTE] It is important to emphasize that quotas for resources in Azure Resource Groups are per-region accessible by your subscription, and are not per-subscription, as the service management quotas are. Let's use core quotas as an example. If you need to request a quota increase with support for cores, you need to decide how many cores you want to use in which regions, and then make a specific request for Azure Resource Group core quotas for the amounts and regions that you want. Therefore, if you need to use 30 cores in West Europe to run your application there; you should specifically request 30 cores in West Europe. But you will not have a core quota increase in any other region -- only West Europe will have the 30-core quota.

As a result, you may find it useful to consider deciding what your Azure Resource Group quotas need to be for your workload in any one region, and request that amount in each region into which you are considering deployment. See troubleshooting deployment issues for more help discovering your current quotas for specific regions.

Search limits

Pricing tiers determine the capacity and limits of your search service. Tiers include:

  • Free multi-tenant service, shared with other Azure subscribers, intended for evaluation and small development projects.
  • Basic provides dedicated computing resources for production workloads at a smaller scale, with up to three replicas for highly available query workloads.
  • Standard (S1, S2, S3, S3 High Density) is for larger production workloads. Multiple levels exist within the standard tier so that you can choose a resource configuration that best matches your workload profile.
