What is Backend Development

If you're not a developer or engineer, topics like front-end and back-end development might be difficult to grasp. When you combine all of the frameworks, programming languages, APIs, and libraries that developers use to create applications, it's easy to get overwhelmed.

Back-end development is the server-side logic that powers websites and applications. It contains all of the code required to build the database, server, and application. A back-end developer may be the skill you need to get your next online project off the ground, from database migrations to API integrations to putting up the server-side technologies that make a website tick.

It may be logging into an account or making a purchase from an website. Back-end developers write code that allows browsers to communicate with database information.

Skills needed to become a backend developer


Servers, databases, and application programming interfaces are the three devices for which backend development is performed (APIs). However, a backend developer should be familiar with the programming languages that these systems commonly use. Python, Java, .NET, Haskell, Clojure, SQL. RoR, and PHP are among these languages.

Let’s take them piece by piece.


Web Development Languages

Backend engineers should be familiar with at least one server-side or backend programming language, such as Java, Python, Ruby, .Net, and so on.

Backend development languages manage web applications' 'behind-the-scenes' functionality. It is the code that links the web to a database, handles user connections, and runs the web application. Backend development collaborates with front end development to provide the final result to the end user.


Database and Cache

One of the most critical Backend developer talents is knowledge of several DBMS technologies. MySQL, MongoDB, Oracle, SQLServer, and Redis are all popular choices for this purpose. Knowledge of caching techniques such as varnish, Memcached, and Redis is advantageous.



Hands-on experience with Apache, Nginx, IIS servers, and Microsoft IIS is preferable. A solid understanding of Linux is very beneficial when it comes to server administration.



Backend developers must also be familiar with web services and APIs. It is preferable to be familiar with the creation of REST and SOAP services.


Other skills needed

Backend developers must understand how servers, databases, and APIs operate. There is no workaround from this. But they must also:

  • Understand accessibility and security compliance;
  • Understand frontend web technologies such as HyperText Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript because they will be working with frontend developers the majority of the time;
  • Manage a hosting environment, including database administration and app scaling when workloads change;
  • Have experience with version control and documentation so other developers can pick up where they left off without getting lost.


Backend Developer Roles and Responsibilities


Backend developers are mostly concerned with how a website functions. They produce code that focuses on the functionality and logic that power the application they're working on, and the technology they're working on is never immediately visible to consumers. 

Here is a list of the main roles and responsibilities of a backend developer.

  • The job of the back end developer is to comprehend the website's objectives and come up with efficient solutions;
  • Keeping data and ensuring that it is visible to the users who should have access to it;
  • Responsible for creating payment processing systems such as receiving data, securely storing that information, and charging that payment;
  • Manage API resources that are applicable to many devices;
  • He or she may be engaged in system architecture and data science analyses;
  • Backend developers are in charge of organizing the logic of the system, which operates across several devices;
  • Back end developers must also be engaged in the development of frameworks or architecture to make it simpler to program against;
  • They should be capable of developing algorithms and resolving system-related issues.

Types of backend languages


Back-end languages range in file size, speed, compatibility, the number of lines of code necessary, and programming style. Some back-end scripting languages are object-oriented programming languages, a programming style that groups properties and functions into objects. 

Other languages may be compiled rather than interpreted, which impacts load time, readability, and the amount of processing power needed to operate the program. Here is a short overview of the most important backend languages.



PHP is the most widely used web back-end language. For use on the back end of websites, PHP offers a short learning curve and the advantage of a vast codebase and a long history of open-source developer community support. If you've ever created a personal website using WordPress, PHP was probably running the back end.



C++ combines all of the characteristics of C with those of object-oriented programming, such as classes. It is used as a low-level programming language to interact effectively with system hardware in order to improve performance. As a result, it is perfect for video games, huge web applications, and other use-cases where system-level speed is critical.


JavaScript (Node.js)

Previously thought to be a front-end scripting language, the release of Node.js demonstrated to the world that this general-purpose object-oriented programming language could also be utilized on the server-side of applications. JavaScript, being one of the web's basic technologies, is currently a popular option for front-end and back-end web development.



Java is an object-oriented programming language that was created with cross-platform interoperability in mind. Java applications may be executed on any system that has the Java Virtual Machine (JVM) installed.


Difference between backend and frontend


Backend development is concerned with what occurs behind the scenes, while frontend development is concerned with the design and interface of the website or online application. Frontend developers are in charge of everything that people view when they use their browsers or apps. As a result, backend and frontend developers must collaborate to provide a unified user experience.

Backend developers should be able to collaborate effectively with other teams. In fact, they are encouraged to submit ideas throughout the early phases of development. Backend developers may encounter issues if they are not engaged in the early phases of development.

The major distinction is that, although backend developers create how a website runs, front-end programmers create and design the interface, which determines how the site appears to users.

Backend web development creates the groundwork for websites to process the actions that users do on the front end and return the proper information.

Neither functions without the other—the back end is required to make the front end operate, and the front end is required so that users can access and interact with the website.

Frontend and backend development have been integrated in recent years to form what is now known as "full-stack development." In this instance, the web developer may work on both the frontend and the backend.




If you're thinking about a career in development, I'd suggest looking at the job descriptions for the positions you're interested in and making a note of the languages that occur the most. Then, start looking for courses using those backend languages you are interested in.

Don't be intimidated by industry jargon. Remember that everyone who is an expert at anything was once a novice.
