Serverless architecture is great and with azure functions, it can reduce your cost and make your azure bill go down.
But if you want to run any long-running task then the azure function needs to be run in-app service plan rather than the consumption plan.
So long-running plans do not make much sense with azure functions. The problem for long-running jobs is now solved with Durable functions.

Durable Function is an extension of Azure Functions and Azure WebJobs that lets you write stateful functions in a serverless environment.
The extension manages state, checkpoints, and restarts for you.

In this webinar, we will look into the demo of the following patterns and their implementations.

01. Function Chaining pattern to execute multiple functions in a sequence
02. Fan-out/fan-in pattern to execute multiple functions in parallel
03. Async HTTP APIs Pattern to solve the problem of coordinating the state of long-running operations with external clients. It simplify the code you write for interacting with long-running function executions.

After this webinar, we will be able to create Azure functions and you will learn how to migrate all your current long-running batch jobs/services
to azure durable functions. So, you will be paying almost zero for these running services.
