With the rise in demands of any time and anywhere computing technology, smartphones, and mobile devices have become a central element of our lives. The key feature of a smartphone is its apps.

A typical mobile user uses multiple apps for nearly all purposes. Some users are dependent on apps for ordering their food online, while some others use it to connect with their family and friends near or far. Many users use apps to check the news, weather, market movements, traffic, book hotels & flights, or even to find a date.

The easy and quick availability of mobile apps has changed how most enterprises go about doing their businesses. Whether you are a small niche store or a multi-national you need to launch company-branded apps to offer your products &services. The ultimate aim is to make your branded app your gateway into the personal world of your consumers and to connect with them in every possible manner.

How Does It All Work?

A mobile app is a piece of marvel and an example of human ingenuity, innovation, creativity, and problem-solving skills. As users use only the public interface of the app, they may confuse it for the entire application. But that is not the case.

Every Mobile app has two parts – the Frontend and the Backend.

1. Frontend


To put it simply, the frontend of a mobile app refers to the look and feel of the app that a user experiences. It involves creating a unique “User experience” or “UX” for the users of the app so that they come back and use it again and again.

It is at the front end of a mobile app where the UI and UX magic are created. This is the layer of the app that end-users download and install from app stores on their phones. 

A frontend developer focuses on how a user interacts with the app, what icons or animation do they see, what actions are permissible, and what is not. They deal with how to present the data that comes from the backend or the server.

Error alerts, notifications, alarms, input validation, presenting data, and sending the inputs to the server to process. Frontend development can be either native (where the native tech stack of the platform is used) or hybrid (where a platform-agnostic stack using HTML5 and JS is used).

2. Backend


The backend works entirely behind the scenes but plays a critical role. It is the backend that does most of the heavy lifting related to data verification, authentication, processing business logic, data storage, and security. The backend of mobile apps is an application hosted on a server that remotely communicates with the frontend.

The backend server can store, retrieve, and sort important information with accuracy and speed to enable a seamless computing experience for the end-users. Any hiccups in the backend can affect millions of users across the world.

The process of designing, developing, deploying, and maintaining the application code at the server-side of a mobile app is called backend development. It encompasses all the activities happening behind the scenes as users interact and interface with the app.

Which data to produce, how to present it, and when to present it is decided by the code that implements business logic. There can be some apps that may only have a frontend and no backend, but such apps would be of very little use. The real power of any dynamic and useful app comes from a strong backend development.

Does A Backend Developer Focus On The Following:

  • App architecture and design
  • Database design and operations
  • Server-side scripting
  • Security, authentication, and privacy
  • Data backup and restoration
  • Load balancing

What Is Frontend vs. Backend Development?

Frontend vs. Backend

Frontend development is application designing and programming with a focus on the visual elements of a software, website, or mobile app. This is the part of the software solution that an end-user interacts with.

Backend development is focused on the server-side of software, website, or mobile app that a typical end-user may never see or use. The backend provides critical support in the form of providing data, verification, authentication, security, and other services.

The frontend and backend are both critical to the success and functionality of any app. They work together seamlessly to bring to life a dynamic mobile app and let users complete their work.

Differences Between A Frontend & Backend Developer

Points Of DifferenceFrontend DeveloperBackendDeveloper
DefinitionThe term frontend refers to the user interface (UI). It is concerned with the effective implementation of the graphical user interface and visual components of a mobile app.Backend means the server, application, and database that work behind the scenes to deliver relevant information to the users.
Skills NeededFrontend development requires a combination of technologies such as Hypertext Markup Language (HTML), JavaScript (JS), and Cascading Style Sheets (CSS).To code applications in the backend, knowledge of programming languages like Ruby on Rails, Python, PHP, Java, C#, and ASP.net is required.
IndependenceExcept for static apps that do not change at all, the frontend development cannot work without the backend.Backend developers work independently of frontend developers. In many cases, some backend applications can function even without a frontend.
ObjectivesA front-end developer has the goal is building an easy-to-use interface to let the users effectively use the product. They ensure that the app is responsive and accessible on all target platforms. The goal of a backend developer is to create a software solution to support the frontend. It supplies many services and supports it with updated data. It must also ensure that the app is secure, and the data in it is processed properly.
Development TeamA typical front-end development team would design a wireframe to determine the structure and design of the app screens based on user requirements. They continually engage with users to seek their inputs, train them, and optimize the design elements for varied smartphones.The backend development must find solutions to complex enterprise problems and implement business logic. They also assist the frontend development team by providing them with a proper API.
Frameworks UsedVue.js, React, AngularJS, and jQuery is the most commonly used frameworks for frontend development.CakePHP, Laravel, Django, Flask, Ruby on Rails, .Net, and CodeIgniter are the most popular backend development.
Additional skillsEffective Knowledge of UI and UX designing with graphics editing skills is a plus.Good aptitude (including problem-solving and logical reasoning), networking, database processing, and communication skills are a must.
Average SalaryThe average salary of a front-end developer may vary from $65,000 to $85,000 per annum.A backend developer usually commands a higher salary package ranging between $75,000 to $110,000.

Role Of Backend App Development

Backend development of mobile apps is the development that occurs on the server-side. The work here secures, stores, and processes data.

1. Strategy


To build an app, software, or website the foremost requirement is a good strategy. Thoroughly research the market and competition, carefully select your target audience, define your goals, and select the right type of platform to launch your app. Then all you need is a great team to develop your app.

2. Design


The UI/UX design process ensures that your app works properly, looks good, and is easy to use. A powerful backend for apps would synchronize your style guides, workflow, architecture, and more.

3. Analysis And Planning

StrategyAnalysis And Planning

Developers can study case studies of different apps and analyze them thoroughly. This allows them to prioritize their app needs. This method will also work as a catalyst in developing the MVP of the app more efficiently.

4. Testing


It is one of the most important aspects of backend development. Different types of testing like unit testing, user testing, performance testing, security testing, and stress testing are necessary. to work consistently on all platforms and under all conditions.

Mobile Application Functions That Are Provided With Backend Development

The basic functions that are utilized while creating mobile applications are:

1. Cloud Server

Cloud Server

Cloud-based servers are now the backbone of all apps these days. This is due to their affordable prices, reliability, scalability, accessibility, and centralized management. The cloud servers are located in protected locations with enough physical and network security to make them secure and safe. Anyone from a large organization to individuals can use the services of cloud servers.

Some popular cloud servers for hosting mobile apps are – Google App Engine, Microsoft Azure, and Amazon AWS.

2. Software-As-A-Service (SaaS)


The cloud servers also offer SaaS as a beneficial add-on. SaaS-based systems offer many backend services to app developers, especially for backend development. SaaS provides ready-to-use backend solutions to apps’ frontend and backend. You can use SaaS-based services for a nominal subscription under a monthly fee.

3. Custom Servers

Custom Servers

If you are handling critical data and need to work with regulators, then you can choose to implement your custom server to host the backend of a mobile app. The Custom backend server can be used to achieve functionalities that SaaS or MBaaS cannot provide – as you would be in total control. The one obvious limitation of a custom server is its price. It also requires a dedicated team to manage and secure it for smooth working. This backend can vary from a simple application server to a complex distributed system according to the need of your app.

Mobile Backend As A Service (MBaaS)

Numerous independent MBaaS services are allowing the user to monitor their applications 24×7. They provide incredible functionalities and analytical frameworks for backend development.

Architecture And Server- Working

Architecture And Server

The backend architecture is a process in which the structure and business logic of an app’s backend is designed. A robust backend architecture allows users to navigate the app and use its different features seamlessly. The user need not worry about the complicated functions going on at the backend.

Backend development prepares your mobile application to work as it was intended to. The backend varies from application to application and can be differentiated based on servers, databases, and middleware

Breaking Down Backend Software Stack

The backend software stack consists of 3 major components

1. Servers


A server is a storage and application processing computer that gather details about user interactions with your app. It can also be used to run specific instances of code depending on the inputs they receive.

2. Database


A database is a repository of relevant data. They contain information that server access to direct app functions. They are also used to securely organize information so that they are easily accessible by the users through the app.

3. Middleware


Middleware is a set of software that connects an application’s backend to its frontend and is deployed on a server of its own. It connects the client and server and is organized in various business and presentation layers.

Middleware provides services such as data communication, authentication, web services, error handling, and data integration by allowing on-premise apps and cloud apps to interact. A good middleware can enhance the apps’ processing, management, user engagement, authentication, and content management.
