What is Azure Functions Consumption Plan?
Azure Functions Consumption Plan is a serverless computing service offered by Microsoft Azure. It allows you to build and run applications without the need to provision or manage infrastructure. With the Consumption Plan, you only pay for the actual usage of your functions, making it a cost-effective solution for various use cases.
Definition
The Azure Functions Consumption Plan is based on the pay-per-use pricing model. This means that you are billed for the actual number of executions and the resources consumed by your functions. The plan automatically scales your functions based on the incoming load, ensuring that you have the required resources when needed.
How it Works
When you create an Azure Function App, you can choose the Consumption Plan as the hosting plan. Once your Function App is deployed, Azure will automatically manage the underlying infrastructure and handle the scaling for you. When a function is triggered, it is dynamically allocated resources to handle the workload. After the function execution is complete, the resources are released, and you are only billed for the actual execution time and resources used.
