Hi @Noam ,
The difference in access to instance hardware types between your production and development web apps might be due to differences in App Service Plan tiers, regional availability, or subscription quotas. Production environments usually have stricter restrictions, and some high-performance instance types, like Premium v3 (P5mv3), might be available in your development environment but not supported in your production plan or region. To fix this, make sure both environments use the same App Service Plan tier and check if the region hosting the production app supports the desired instance type. Also, check subscription quotas in the Azure portal to ensure your production environment allows access to these hardware types. You can review and upgrade your App Service Plan via the Azure App Service Hosting Plans documentation and check regional availability in the Azure Scaling FAQ."
