Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
This is likely not your Microsoft.Compute vCPU quota.
App Service Plans use Microsoft.Web / App Service quota, and Azure may surface it as “Total VMs” because an App Service Plan consumes an App Service worker instance behind the scenes. Your “Total Regional vCPUs 0 of 20” only tells you Compute VM quota is available, not App Service Plan SKU quota. Microsoft’s quota docs separate service-specific quotas, and App Service quota requests are handled separately from Compute vCPU quotas.
For a Visual Studio Professional Subscription, this can happen because dev/test credit subscriptions may have 0 quota for certain App Service SKUs/regions until enabled or increased. The subscription includes Azure credit and can be used for Web Apps, but it is still subject to service/region/SKU quotas.
Possible Fix
- Go to Azure Portal → Subscriptions → your Visual Studio Professional subscription
- Open Usage + quotas
- Change Provider from Microsoft.Compute to App Service / Microsoft.Web
- Filter by the region and SKU family you are trying to create, such as:
- F1 / Free
- B1 / Basic
- S1 / Standard
- P0v3 / P1v3 / Premium
- Request quota increase from 0 to at least 1
- Retry deployment after approval
Microsoft Q&A guidance for this exact App Service error recommends using the App Service quota self-service experience or opening a quota/support request for the specific App Service SKU and region.
Why multiple regions/SKUs failed
Quota is often enforced by service + region + SKU family, so you may have Compute quota everywhere but App Service worker quota = 0 for the plans you’re testing. Request the quota for the exact SKU/region, or try a low-cost SKU in another region after checking App Service quotas, not Compute.
Practical recommendation
Request App Service Plan quota = 1 or 2 for your preferred region and SKU. For Visual Studio credit subscriptions, I’d start with B1 or S1 rather than Premium unless you specifically need Premium features.
