Announcing: Resources for migrating to Azure Functions Flex Consumption
Azure Functions Flex Consumption is
now the recommended hosting plan for serverless workloads requiring advanced
scaling, networking, and cost optimization. To support customers migrating from
the Azure Functions Consumption plan or from AWS Lambda, Microsoft has
published comprehensive migration guides and tooling:
- Azure Functions Consumption to
Flex Consumption: The new documentation provides step-by-step instructions
for moving your Azure Functions apps from the Consumption plan to Flex
Consumption. This includes guidance on updating your infrastructure as code
(ARM/Bicep), configuration changes, and leveraging new AZ CLI commands to
automate the migration process.
AWS Lambda to Azure Functions Flex Consumption: For customers migrating from AWS Lambda, this guide covers mapping Lambda concepts to Azure Functions, code porting strategies, and best practices for deploying to Azure Functions Flex Consumption. This includes instructions for using GitHub Copilot in VS Code for help with code refactoring, manual refactoring for specific changes, or other migration aids.
These resources are designed to minimize downtime and ensure a smooth
transition, enabling customers to take advantage of Flex Consumption’s improved
scaling, networking, and cost controls.
