The Azure Functions Linux Consumption hosting plan is being retired. Customers are advised to migrate to the Flex Consumption plan, which offers faster scaling, advanced networking, cold start mitigation, and concurrency control. To identify affected resources, check the Azure portal for App Service plans with Pricing Tier: Dynamic (Y1: 0) and Operating System: Linux. Key dates:
- After September 30, 2025: No new features for Linux Consumption; it will be removed from the Azure Portal, Visual Studio, and VS Code, but can still be managed via infrastructure as code and Azure CLI.
- After September 30, 2028: No technical support or ability to create new Linux Consumption function apps.
Please migrate to Flex Consumption by September 30, 2028, to avoid service disruptions. Microsoft will provide migration documentation and tools throughout the transition.
