Serverless solutions like Azure Functions let you create less code, manage less infrastructure, and spend less money. The cloud infrastructure offers all the modern resources required to keep business applications running, so you don't have to bother about setting up and managing servers.

Azure Functions takes care of the rest while you concentrate on the parts of the code that are most important to you.

We frequently design systems to respond to a string of important events. Every application needs a method to execute some code as these events take place, whether you're developing a web API, reacting to database updates, analysing IoT streams of data, or even maintaining message queues.

Azure Functions offers "compute on-demand" in two important ways to satisfy this need.

The first is that Azure Functions enables you to convert the logic of your system into readily accessible units of code. They are referred to as "functions" in the code. Various processes can run whenever you need to react to urgent situations.

Second, when demand grows, Azure Functions scales up to meet it with the resources and functional instances required, but only when they are required. Any additional resources and software instances automatically disappear when requests decrease.

Where do all of the resources for computation come from? To match the demands of your application, Azure Functions offers as many or even as few computing resources as necessary.

The core of serverless computing with Azure Functions is the provision of computational resources on-demand.
