Azure Function App mode is a deployment option for Azure Functions that allows multiple functions to run in a single app. This mode is ideal for scenarios where you have many related functions that need to share resources or operate on the same data.
In Function App mode, all the functions in your app share the same hosting plan and runtime environment. This means they can share resources like memory and CPU, which can help optimize performance and reduce costs.
Function App mode also provides a range of features for managing and monitoring your functions, including built-in logging, alerts, and diagnostics. You can also use Azure DevOps or other CI/CD tools to automate deployment and testing.
Overall, Function App mode is a powerful way to build scalable, efficient serverless applications with Azure Functions.
