Request a quota limit increase for Microsoft Dev Box resources

This article describes how to submit a support request to increase the number of resources for Microsoft Dev Box in your Azure subscription.

To ensure that resources are available for customers, Microsoft Dev Box has a limit on the number of each type of resource that can be used in a subscription. This limit is called a quota.

There are different types of quota limits that you might encounter, depending on the resource type. Here are some examples:

  • There are limits on the number of vCPUs available for dev boxes. You might encounter this quota error in the Microsoft developer portal during dev box creation.
  • There are limits for dev centers, network connections, and dev box definitions. You can find information about these limits through the Azure portal.

When you reach the limit for a resource in your subscription, you can request a limit increase (sometimes called a capacity increase, or a quota increase) to extend the number of resources available. The request process allows the Microsoft Dev Box team to ensure your subscription isn't involved in any cases of fraud or unintentional, sudden large-scale deployments.

The time it takes to increase your quota varies depending on the virtual machine size, region, and number of resources requested. You don't have to go through the process of requesting extra capacity often. To ensure you have the resources you require when you need them, you should:

  • Request capacity as far in advance as possible.
  • If possible, be flexible on the region where you're requesting capacity.
  • Recognize that capacity remains assigned for the lifetime of a subscription. When dev box resources are deleted, the capacity remains assigned to the subscription.
  • Request extra capacity only if you need more than is already assigned to your subscription.
  • Make incremental requests for virtual machine cores rather than making large, bulk requests. Break requests for large numbers of cores into smaller requests for extra flexibility in how those requests are fulfilled.

  • To create a support request, your Azure account needs the Owner, Contributor, or Support Request Contributor role at the subscription level.
  • Before you create a support request for a limit increase, you need to gather additional information.

Gather information for your request

Submitting a support request for an increase in quota is quicker if you gather the required information before you begin the request process.

  • Determine your current quota usage

    For each of your subscriptions, you can check your current usage of each Deployment Environments resource type in each region. Determine your current usage by following the steps in Determine usage and quota.

  • Determine the region for the additional quota

    Dev Box resources can exist in many regions. You can choose to deploy resources in multiple regions located near to your dev box users. For more information about Azure regions, how they relate to global geographies, and which services are available in each region, see Azure global infrastructure.

  • Choose the quota type of the additional quota

    The following Dev Box resources are limited by subscription. You can request an increase in the number of resources for each of these types.

    • Dev box definitions
    • Dev centers
    • Network settings
    • Network connections
    • Dev Box general cores
    • Other

    When you want to increase the number of dev boxes available to your developers, you should request an increase in the number of Dev Box general cores.
