Introduction

In the world of serverless computing, the Azure functions act as modern serverless architecture. It helps in delivering cloud computing and configures to comply with application development. Through Azure functions, we can author and execute snippets of code in the cloud without the hassle of managing the web servers and containers. It lets us run small pieces of code and makes developers bother free about the infrastructure of the platform on which it is executed.

By using Azure Functions, we can call Function-as-a-Service which eliminates infrastructure considerations for the developer. Even they can be scaled according to demand.
To build applications, developers can use their own choice of programming language. Azure provides full freedom to developers to work optimally.

Features of Azure Functions

Azure also provides the added benefit of Iaas and PaaS, with cloud infrastructure. Here some of the features are highlighted below:

Intuitive, browser-based user interface – We can write our code in easy-to-use web interface and use our favorite development tool to build and debug. Azure Functions have an intuitive browser-based user interface which responds to the events generated by Event Hubs, HTTP Requests, etc.

Variety of programming languages – The service accepts a variety of programming languages like C#, F#, Node.js, Java, Python, PHP. The developer has full freedom to choose the programming language of his/her choice.

Capabilities for implementing code – The application platform has capabilities to implement code triggered by events that occur in any third-party service or on-premise system.

Supports Continuous Deployment and Integration – The Azure is a serverless structure but still, it needs Continuous Deployment and Integration. This Continuous Deployment and integration are done through GitHub, Visual Studio and some other tools.

Azure Functions Input-Output – Binding makes it easy for the developer because with it the developer doesn’t have to know about the service deeply. The triggers in the binding help the developer to avoid hardcoding.
Developers can send data like queueing the message, with the help of the return value of the function, a collector object or an out parameter.

Azure Functions Monitor Events

Azure Functions act as a readymade template that contains a set of predefined functions that showcase a working scenario. To perform complex functions it acts as a repository. Here are some monitor events:

HTTPTrigger – The Azure Functions support HTTP requests.

GitHub Webhook – To set up the GitHub app, first, we have to install the Webhooks. This thing will help in the integrations that subscribe to certain GitHub events.

Generic Webhook – This almost like a messaging format through which we can chat with the application.

BlobTrigger – With the help of this, we can trigger a function when a blob is updated.

QueueTrigger – QueueTrigger helps a function when a new update comes up in the queue. The queue message is like an input to the function and might even resend the message for a retry loop.

ServiceBusQueueTrigger – Through this function developer can execute his/her code every time when a service bus received a message.

ServiceBusTopicTrigger – When the service bus topic function is triggered, the developer can publish and push messages to the topic.

With a fully managed to compute platform, Azure Functions provides high-level reliability and security for your apps. Whenever you want to scale your app in peak season or in high demand, this platform will make your work easy.
