Answer "No" is correct. Always On enables waking up on HTTPTrigger, but does not prevent the exceeding the max time out time of 230 seconds. https://docs.microsoft.com/en-us/azure/azure-functions/dedicated-plan#always-on

No is the answer, but the reason is the timeout being raised by HTTP layer from the Azure Load Balancer, not the App layer that at least it gives 5 minutes for the cheapest type, Consumption, so however you enhance the app layer, the http layer Azure Load Balance will not wait more than 230 second and will reply it as timeout. Use the durable function pattern to poll the status for completion will be the easiest solution, else avoid the http layer like service bus will work too. https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#timeout:~:text=1%20Regardless%20of,immediate%20response.

Answer is still 'No' but default time for dedicated host is 30 mins, it can be technically configured to infinite...but have to do that manually and that is not mentioned in solution. ref: https://docs.microsoft.com/en-us/azure/azure-functions/functions-host-json#functiontimeout

CoPilot Says Option as Yes. Yes, the solution meets the goal. By configuring the app to use an App Service hosting plan and enabling the Always On setting, you can prevent the app from timing out and ensure that it processes the blob data successfully.

https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale#timeout Regardless of the function app timeout setting, 230 seconds is the maximum amount of time that an HTTP triggered function can take to respond to a request. This is because of the default idle timeout of Azure Load Balancer.

"Always On" feature of Azure App Service is to keep the host process running to allow more responsive to requests after significant idle periods. This is UNRELATED to the timeout. So the answer is obvious!!

Correct Answer: No Always On enables waking up on HTTP trigger, but does not prevent the exceeding the max time out time of 230 seconds. If you run on an App Service plan, you should enable the Always on setting so that your function app runs correctly. On an App Service plan, the functions runtime goes idle after a few minutes of inactivity, so only HTTP triggers will "wake up" your functions. The Always on setting is available only on an App Service plan. On a Consumption plan, the platform activates function apps automatically.

Answer is YES "Best for long-running scenarios where Durable Functions can't be used. Consider an App Service plan in the following situations:" link: https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#overview-of-plans another link https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#timeout that mentionned the duration is 30 min and upper
