As mobile applications continue to gain immense popularity, the focus has shifted towards building exceptional apps rather than common ones. An efficient mobile app backend is crucial to providing a seamless user experience.

In this article, we will see the importance of backend development, explore the software stacks commonly used in backend architecture, and uncover the tools that help develop a strong backend process.

What is Frontend vs. backend development?
If you ask a developer how frontend and backend development are different, the answer that you will get is that the frontend focuses on codes to make an app look pretty and the backend writes codes to make it work.

However, there are several fundamental aspects on which both app development processes rely.

Basically, applications installed from the Play Store or App Store on your smartphone fall into the category of front-end applications. Whether it’s Instagram, Facebook, or even a simple calculator app, each resides within your smartphone as a front-end mobile application. How does this work? Frontend applications enable direct ...
... interaction through buttons, text fields, swipes, and more. Since they operate on mobile devices, they are, by definition, mobile applications.

A frontend developer’s responsibility lies in translating the app’s design into code that ensures it displays correctly in web browsers. With the advent of responsive web design, this task has become more intricate. Developers must ensure that the design is compatible with various browsers, mobile platforms, computer resolutions, and browser widths.

Now that you have understood frontend development, let’s explore backend development.

In simple terms, you can assume the backend is an extra application for your mobile application. It’s a software component that runs on servers, providing the essential functionality of the application. This encompasses elements like servers, databases, middleware, and more, accessible via the internet through an Application Programming Interface (API).

A backend developer’s role is to establish the connection between the mobile app, the server, and the content one sees on the app. They create the logic necessary to ensure everything functions as intended. On the design front, they convert designs and frontend development processes into a Content Management System (CMS) setup, providing clients with an intuitive method to manage their app’s content. Striking the right balance is critical. If they make the mobile app backend architecture simple, chances are that the clients will not have control. And if they make it complex, the possibility that clients get lost in the design becomes high.

Mobile Application Functions That Are Provided with Backend Development
Before integrating a mobile backend for app development, several crucial considerations should be addressed. The fundamental functions to utilize while creating mobile applications are:

Cloud Server: Nowadays, cloud servers are within reach of virtually everyone. They come in various sizes and are stored in a protected location. Prominent cloud servers like Google App Engine, Microsoft Azure, and Amazon AWS are favored by large organizations for their reliability.
Software-as-a-Service (SaaS) or Third-Party Services: Often, the functionalities required for your app may already be provided by existing services. These services offer readily available backend solutions tailored for front-end apps. All you need to do is register and subscribe to a monthly fee, and you’ll have a fully functional backend at your fingertips in a matter of clicks or seconds.
Mobile Backend as a Service (MBaaS): If you prefer not to write your own backend servers or put resources into a cloud-based server, MBaaS is an alternative worth considering. Today, there are numerous independent MBaaS providers offering robust functionality and an analytics framework to monitor your applications.
Custom Server: The most flexible and powerful option is a custom server. Anything that can’t be achieved with SaaS or MBaaS can be accomplished with a custom backend. Naturally, this option comes with the drawback of setup and implementation costs. It necessitates either a dedicated backend programmer or an entire team. The custom backend can range from a simple application to a complex distributed system, depending on the specific requirements of your app.
Backend software stack components
The backend software stack consists of three major components.

1. Server
When considering the backend of a mobile app, it becomes evident that the server, specifically a backend server, must play a critical role. A backend server is a group of interconnected servers working together to provide resources and storage for the mobile app and its various functionalities. These resources include security, email services, databases, and web services.

Servers come in various forms, each with its own unique advantages. Whether you choose a physical server, a virtual server, or a containerized server, there are compelling reasons for adopting one. Essentially, a server acts as a central computer, housing multiple interconnected computers within it. This configuration enables companies to establish centralized locations for storing all their data securely in one centralized repository.

2. Database
A database stands as a fundamental component of any robust application; it is the engine of a vehicle. The engine, like the database, gives you instant access to all your stored data and keeps you informed about the maintenance parts when they fail.

Designed to be the heart of your application, a database stores all your data and enhances the user experience through secondary tools. While there are various types of database schemas and configurations, they all fundamentally share the same objective: the storage and retrieval of data.

3. Middleware
Middleware is a type of software that serves as a bridge between the presentation layer of your application and the server. It consists of a collection of libraries that operate on the server, establishing a connection between your business layer and the backend code. This allows you to create your UI without worrying about the production or how it’s going to be designed on the screen.

However, middleware serves as a vital link connecting on-premises applications with cloud-based apps. It establishes a connection between native resources and cloud services. This helps accelerate business process management and gives a unified experience to users across platforms.

List of Top Backend Development Tools
1.Web Server Tools
The backend server of a mobile app serves the purpose of storing, processing, and delivering data to the apps installed on end users’ phones. The communication between the server and the clients is secured for data protection.
