[Microsoft Fabric] Quotas

• depend on the Azure subscription type [5]
• set and enforced in the scope of the subscription [1]
• each subscription has a default value for each quota [1]
• determine the maximum number of CUs for each of the capacities on the subscription [5]
• customers don't get charged for quotas, but on capacities [5]
• each quota represents a specific countable resource
• e.g. number of VMs that can be created [2]
• e.g. the number of storage accounts that can be used concurrently [2]
• e.g. the number of networking resources that can be consumed [2]
• e.g. the number of API calls to a particular service that can be made [2]
• designed to help protect customers from unexpected behavior [1]
• e.g. inaccurately resourced deployments, mistaken consumption
• helps minimize risks from deceptive or inappropriate consumption and unexpected demand [1]
• limitations
• ⇐ some limits are managed at a regional level [2]
• ⇐ variable and dependent on several factors
• {type} adjustable quotas
• quotas for which customers can request quota increases
• via Azure Home My quotas page
• based on amount or usage percentage and submitting it directly [1]
• each subscription has a default quota value for each quota [1]
• the quickest way to increase quotas [1]
• {type} non-adjustable quotas
• quotas which have a hard limit, usually determined by the scope of the subscription [1]
• to make changes, customers must submit a support request for the Azure support team [1]
• [Fabric] limit the number of CUs customers can provision across multiple capacities in a subscription
• calculation based on
• subscription plan type
• Azure region
• {action} provision a new capacity
• {level} Azure management group limits
• {level} Azure subscription limits
• {level} Azure resource group limits
• {level} Template limits
• {level} Microsoft Entra ID limits
• {level} Azure API Center limits
• {level} Azure API Management limits
• {level} API Management v2 tiers
• {level} Azure App Service limits
• {level} Azure Automation limits
• {action} request quota increase
• via support request
• there is no cost associated with requesting a quota increase [1]
• ⇐ costs are incurred based on resource usage, not the quotas themselves [1]
• should be based on workloads' characteristics [1]
• {action} view quota
• [permission] contributor role, or another role that includes contributor access [5]
• {action} manage quota
• [permission] see Quota Request Operator
