What are Azure Functions?

Azure, Microsoft’s cloud computing platform, provides many services and capabilities. It aids in developing, deploying, and managing applications and services for people and businesses. Users may choose from these services to create and grow new applications or operate current apps on the public cloud. Microsoft Azure offers a serverless computing solution called Azure Functions. Users can develop and execute programs in the cloud without handling the supporting infrastructure. They can create applications that are event-driven, scalable, and highly accessible by running short bits of code known as “functions” in response to certain triggers or events.

Azure Functions

Azure Functions

Functions is an on-demand cloud service that offers the resources and upgraded cloud infrastructure needed to operate the apps. Developers use Azure Function to take actions by connecting to data sources, which makes it simple to process and react to events. Developers also use Azure Function to develop HTTP-based API endpoints that can be used by a wide range of apps, mobile devices, and Internet of Things (IoT) devices. 

Azure Function is used to achieve decoupling, high throughput, reusability, and shared. It is more reliable and can be utilized in production circumstances. Only users with a valid Azure subscription and an Azure Storage account can access Azure features. Moreover, Azure serverless functions offer the user a browser-based user interface. It supports most well-known programming languages, including C#, Java, Python, PHP, Bash, PowerShell, and many others.

Benefits of Azure Functions

Cost-effective: Functions is available on a pay-as-you-go basis. The user only pays for what they use.

Fast: Depending on the workload, Azure Function is quick, generally taking only a few seconds to begin and finishing execution in a few minutes.

Simple: The serverless architecture handles user code testing, so there is no need to start a server.

CI/CD friendly: It integrates well with Azure DevOps and other continuous integration and deployment (CI/CD) tools.

Hybrid and Edge Computing: Azure Function support hybrid and edge scenarios. Users can easily install and run functions on edge devices, allowing local processing and lowering latency.

Azure Function Features

The serverless aspect of Azure Function brings several significant capabilities that easily interact with the core Azure services. The following are some of the features of the Azure function.

Trigger-based executions

When an event is fired, the Azure function begin to operate. Functions setup provides dozens of triggers that can be configured when an Azure function is executed. Executions using triggers save labor costs significantly and promote creativity. Users might no longer require Administrators to manually handle frequent occurrences and tasks.

Supports different programming languages

Functions give programmers a comprehensive toolkit for creating, debugging, and deploying code in today’s well-known programming languages. It includes C#, Java, F#, PHP, Node.js, Python, and PowerShell. Functions give developers the freedom to select the programming language to use. Additionally, programmers have access to various programming paradigms for activities like creating HTTP-based APIs.

No server set up for applications

Azure functions are serverless, meaning they can be deployed and used without virtual machines or web servers. Developers may create web APIs, perform serverless computing, respond to database changes, interpret IoT feeds, and manage message queues using Azure functions. Since Azure is a serverless service, it increases scalability and efficiency and can be connected to several different on-premise or cloud-based applications. It also reduces the developer’s time and needless stress to worry about the infrastructure.

Easy to write and deploy

The Azure function is simple to develop, test, debug, and deploy due to its nature. Businesses don’t need a larger team to do that; one developer can handle every task. Because there is no huge application, startup time, initialization, or other events fired before the code is performed, the Azure function run quickly. The Azure function uses compute-on-demand, which is scalable by design. When there is greater demand for execution, the service is automatically given more resources, and when there is less demand, all excess resources and application instances are immediately decommissioned.

Platform agnostic

Azure functions are platform agnostic and run in their own process and environments. Developers use Linux, Windows, or containers to deploy Azure function in any configuration. However, if an application has access to the function, it is available and used with Azure function. Azure function are independent. Upgrades to Azure function is simple and have no impact on other components of a website or other apps. Additionally, Azure function may interface with other APIs, databases, and libraries using standards adopted by the industry. This increases the usability of Azure services in cloud-native apps.


Azure Function can be a valuable tool in your cloud development toolkit. It offers an effective and adaptable serverless computing platform that facilitates event-driven architectures, streamlines development, increases scalability, and lowers costs. Professionals who wish to learn more about Azure Function can enroll in the Microsoft Azure Developer Associate Training  (AZ 204). Professionals that have undergone training can create and optimize Azure solutions and utilize Azure services. These abilities enable them to contribute to various stages of cloud development.
