Azure Functions: How can they help me?

A practical use case

Here is a practical use case for Azure Functions:

✅ Azure function is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs of servers.

✅ It is one of the services provided by Microsoft on Azure cloud. Azure provides all the up-to-date resources needed to keep your applications running.

👍 My favorite part? Its native support for C#, Java, JavaScript, PowerShell, Python while custom handlers can be implemented for other langs like Rust & Go.

😎 That means you are not limited to C# or the .NET framework. You write your function code in your preferred language using your favorite development tools and then deploy your code to the Azure cloud.

We often build systems to react to a series of critical events.

Whether you're building a web API, responding to database changes, processing event streams or messages, Azure Functions can be used to implement them.

Azure Functions provides a comprehensive set of event-driven triggers and bindings that connect your functions to other services without having to write extra code.

A typical scenario where Azure function is the best choice is responding to database changes.

Before SQL trigger Azure functions, you'd have to implement a custom change tracking mechanism to poll for changes to a table or database.

With Azure functions, you can create a function that will be triggered every time a row is created, updated or deleted.

In this case, you set up an azure function with an SQL trigger.

The only code you need to write is what happens when the trigger occurs. You have access to values from the trigger which can be used inside your function as an input.
