However, application development was never as effortless as it is with the low code or serverless application development of Azure and PowerApps.

This application development approach has set new highs of effortlessness when the development of business-focused, quick, cost-effective, and quality-oriented application development is the key concern.

What makes it different from other kinds of application development approaches and what is worth its holds in the world of application development?

These are some of the questions which we will try to resolve in this post. So, if you’re also curious to know about serverless applications then stay tuned.

What Do We Mean By Serverless Application?

Before we delve deep into details, let’s get familiar with the concept of serverless applications. With serverless, we mean the process of managing the servers, by the cloud provider, for executing cloud computing rather than the businesses.

Going by this definition, we can conclude that the serverless applications are the ones that run the servers, managed entirely by the cloud service provider. In this model of applications development, the end-user is not liable to:

· Look after the servers and related equipment as the cloud service provider is handling the job.

· Bear the set-up and installation costs of any sort as the cloud service provider is handling that

· Pay attention to the security of the servers

· Bear the hardware cost, involved in the application development

All of this happens at a monthly subscription cost that the end-user pays. All a customer needs to do is to perform the applications’ testing & coding. Not only the tediousness, involved in application development, is reduced with serverless application development but also faster time to market is enjoyed as there is no need to get involved in procuring and obtaining the resources.

When to Consider Serverless Application Development

This model is going to make a huge difference when:

· There is a need of executing asynchronous and concurrent tasks with full perfection.

· You need to immediately change and deploy application code as per changing business requirements.

· You want to server to infrequent requests and varying customers/user traffic while there is no dependency on latency.

· There is a need to quickly iterate the application development.

· Building MVPs is the goal.

For its Azure users, Microsoft offers Azure Functions and Logic App technologies to make serverless application development possible.

How to Get Started With Serverless Application Development?

Getting started with serverless application development is an easy task that starts with writing the code in the containers. On executing the written codes/event, you can trigger any of the managed services or custom resources.

Afterwards, the end-user is suggested to write the stateful functions in a given serverless computing system.

The written serverless code is event-driven is stays running in the response to the given triggers.

Serverless PowerApps

Serverless PowerApps is empowered by Azure Functions, serverless solutions designed to allow end-users to develop an application with fewer code writing and less architecture maintenance. PowerApps, in combination with Logic Apps and Azure Functions, offers the building blocks APIs, used for connecting the custom system backends and data models.

These blocks of APIs, when integrated with PowerApps, hold the power to integrate the business-critical data, leveraging the quick application built, management of apps, and effective apps distribution.

Backend serverless APIs can be built and imported in MS PowerApps as custom connector(s) using the Azure AP Management functionality since the ‘Fusion Development’ teams are made available by Microsoft.

They can further be used as custom connectors. That was for the seasoned developers. Citizen developers with less developing experience or novice developers can also achieve perfection in serverless application development, using the PowerApps APIs as there is no need to write front-end codes. This way, it’s possible to save a huge deal of time & effort, invested in app development.

PowerApps has already gained popularity across the developers’ community as it supports low code development and can be used for multiple processes like automation, reporting, collaboration, visualization, and many more.

With the integration of PowerApps and Azure, developers can build an API in Visual Studio Code and then publish it on the Azure portal. API export to PowerApps can also be done effortlessly.

The same API can be re-used an endless number of times in the Power Apps’ studio and streamline the future application development.
