What Azure Functions are and How You Can Use Them to Run Small Applications Effortlessly

Develop more efficiently with Functions, an event-driven serverless compute platform that can also solve complex orchestration problems. Build and debug locally without additional setup, deploy and operate at scale in the cloud and integrate services using triggers and bindings.


Serverless computing is the word of the day, and Microsoft Azure Functions acts a modern serverless architecture delivering event driven cloud computing and configured to comply with application development. Through Azure Functions, you can author and execute snippets of code in the cloud without the hassle of managing the web servers or containers. So that’s why we say it has serverless architecture. It lets you run small pieces of code and the developer doesn’t have to worry about the infrastructure of the platform on which it is executed.

This way, Function-as-a-Service becomes a generic term for serverless and eliminates infrastructure considerations for the developer. Of course, servers are there, but the user doesn’t have to bother with managing or provisioning them. They can even be scaled according to demand. To build the apps themselves, the developers can use their own choice of programming language, giving them the freedom to work optimally.
Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date servers needed to keep your applications running.

You focus on the pieces of code that matter most to you, and Azure Functions handles the rest.
We often build systems to react to a series of critical events. Whether you're building a web API, responding to database changes, processing IoT data streams, or even managing message queues - every application needs a way to run some code as these events occur.

To meet this need, Azure Functions provides "compute on-demand" in two significant ways.

First, Azure Functions allows you to implement your system's logic into readily available blocks of code. These code blocks are called "functions". Different functions can run anytime you need to respond to critical events.

Second, as requests increase, Azure Functions meets the demand with as many resources and function instances as necessary - but only while needed. As requests fall, any extra resources and application instances drop off automatically.
