Azure Function in Consumption Plan Not Triggering (But Works in Premium) I'm working with an Azure Function app that utilizes the Consumption plan. The function seems to execute flawlessly when deployed to the Premium plan, but it doesn't trigger at all in Consumption. I've verified the function code itself works as expected.
Here's what I've tried so far:
Manual Invocation: I've manually triggered the function through the Azure portal and it executes successfully in both Consumption and Premium plans. This suggests the function code itself is functional. Trigger Configuration: I've double-checked the trigger configuration (e.g., Blob storage connection string) and ensured it's accurate for both plans. Trigger Source Testing: I've simulated the trigger event from the source (e.g., uploaded a test blob) to see if the function fires in Consumption, but there's no response. Has anyone encountered this behavior with Azure Functions in Consumption plans? Any insights or suggestions on troubleshooting steps would be greatly appreciated!
The Azure Functions Consumption Plan doesn't come with a Service Level Agreement (SLA). This is because it's a serverless model where Azure automatically adjusts resources based on demand. You only pay for what you use. Since resources are allocated dynamically, there's no guarantee on availability or performance.
The plan is flexible and cost-effective but has some trade-offs. Your app runs on shared infrastructure, so performance can vary, especially if it hasn't been used recently or if demand is high. Azure scales your app based on traffic, but there could be delays during high demand.
While Azure aims for high availability, it doesn't guarantee it for the Consumption Plan. If your app has been idle, there might be a delay when it starts processing a new request.
If you need guaranteed availability and performance, consider other Azure Functions pricing plans that offer SLAs.
