Serveless Mobile Application

Serverless Mobile Application: The concept is known to many but yet explored less. The digital world is going all gaga about the word “serverless computing,” and we thought it is the best time to acknowledge our clients and readers with the concept of the serverless mobile application.

Serverless apps might sound new, but popular apps like Airbnb, Nike, and Netflix have already embraced the serverless architecture benefits. Serverless computing or function has become some popular domains demanding a lot of attention in the industry. The serverless architecture market is expected to cross $9.17 billion by the end of the year 2023. The figure definitely raises an eyebrow and boosts the enthusiasm to move towards the serverless mobile app concept.

We will begin this blog with the fundamental question that you all may have!

What are serverless applications?

The word serverless means without a server (not literally), meaning the server is not seen, but only the code is visible. The code logic runs in the same way as it would with the physical servers and operating systems. But the OS, virtual machines, and servers are nowhere seen in the concept.

Serverless mobile app development demands mobile app developers to focus majorly on crafting clean and concise codes.

Serverless mobile applications usually use two approaches:

- Function-as-a-Service

- Backend-as-a-Service


In this cloud computing service offering, the users can write code, and service providers manage the rest. The application requires server-side logic, and the users can develop and execute stateless functions & business logic that is reflected in the front-end.

In Function-as-a-Service, the app uses a microservices architecture for easy and smooth functioning.


In this cloud computing service offering, all the behind-the-scenes aspects are outsourced to the service provider, thereby automating back-end development. The internal state of the logic is maintained, and everything depends on the third-party services.

Pros and cons of Serverless apps

Why go serverless? What are the pros and cons of serverless apps?

More than the disadvantages, there are several benefits of a serverless mobile application. An experienced mobile app development company will guide you through the serverless mobile app advantages in advance when you approach them with the app idea.

Let us highlight the advantages of it.

Saves money:When companies opt for serverless mobile applications, various tasks such as image processing, presence detection, etc., are being taken care of by the virtual servers.

Also, when you use serverless clouds, namely AWS, Google Cloud, or Azure, you only have to pay for what you use. This means you pay only for the data you use. Companies do not have to invest any extra money in monitoring activities and thereby save themselves from any application downtime.

Faster app development:Application scalability is an important factor that contributes to faster app development. The cloud computing service provider can easily execute the functions individually and optimize them automatically. This further means, all the changes are integrated and validated

The automation of code change implementation defines a seamless workflow, and the entire complex task can thereby be divided into small tasks. Serverless mobile app development also helps in increasing the productivity of the teams working on the project.

Allows you to focus on user experience:As mentioned above, every hardware maintenance task is maintained by a third party, and companies do not have to invest their time in the same. The time that you invest behind the same tasks can now be diverted to tasks that help you improve the application’s user experience.

Ease of migration:Serverless mobile applications allow you to treat each feature separately. Your hired mobile app developers or in-house team can address the creation & encoding of metadata.

Faster time to market:It is quite obvious that the automation of the tasks gives you complete control over the entire mobile app development process. The third-party or the cloud service provider vendor is responsible for handling the security concerns and performance concerns of the server.

This way, the whole app development cycle speeds up, resulting in a faster time to market.

Now, let’s discuss the disadvantages/cons of serverless computing!

Difficult learning curve:The main challenge that one faces during serverless application development is to implement FaaS tools. The comprehensive documentation does the favor, but it is difficult to learn FaaS tools for the first-timers.

Difficulty in debugging:For complex applications that involve a large number of individual functional containers, it is quite difficult to debug the app. Developers can not use a debugger in the public cloud domain, which makes the debugging process tedious.

So, that’s all about the pros and cons of a serverless mobile application. We will also name some of the popular serverless cloud providers doing their best for the industry.

1. AWS Lambda;

2. Google Cloud Functions;

3. Microsoft Azure Functions.

You may get in touch with us if you wish to learn more about the comparison and use cases of the above serverless cloud providers. Our experts will let you know the details by answering all your questions.

In the end…

Serverless application frameworks and computing resolve almost every common app development problem. It helps in scaling, maintaining, and building a seamless application within the shortest possible time.

The two-pillar, Continuous Integration and Continuous Delivery, play a vital role in delivering high-quality mobile applications. To join in the growing trend and learn more, please fill up our contact us form!
