There has been a longstanding trend towards improved usability, and frontend developers closely collaborate with UI and UX designers. However, even a perfectly designed frontend will only yield results if the backend is kept up-to-date. This hidden layer, imperceptible to the user, holds significant importance.

According to Stack Overflow, more than 50% of developers consider themselves full-stack developers. Recent surveys emphasize the importance of having knowledge in both backend and frontend development.

Consequently, project managers are taking note of the growing backend market. The demand for backend frameworks for web and mobile applications is rapidly increasing. This market offers numerous opportunities for business owners.

Common examples of backend technologies include Node.js, Ruby on Rails, Django, PHP, Python, .NET, Spring, and Java. Let's examine each technology individually.

Java: once again a leader in backend technologies

Java has maintained its position as an industry leader for nearly 30 years. According to Stack Overflow surveys, it ranks as the third most popular statically typed, object-oriented scripting language used for backend web development.

Java applications are compiled into bytecode, making them portable to any device with a Java Virtual Machine (JVM) installed. This scripting language offers a wide array of technologies, including backend frameworks such as Grails and Spring, libraries, databases, Integrated Development Environments (IDEs), Docker for containerization, and the Java Development Kit.

The core Java features:

  • Advanced automatism

The Java Virtual Machine offers automatic memory management to track redundant or unused objects in the code and remove them automatically. This process is known as garbage collection, and it occurs by default.

  • Maximum performance with a multi-threaded web server

Java developers can run multiple processes simultaneously, and their execution is entirely independent; one process doesn't interfere with the other. This multithreading capability is one of the reasons Java is highly recommended for processor-intensive application development.

  • Open-source libraries

Java backend technologies can significantly improve the speed at which tasks are executed on the server side. In the Java ecosystem, you can find libraries for messaging, JSON (JavaScript Object Notation) parsing, unit testing, and many more.

  • Cybersecurity

To safeguard sensitive data from unauthorized access, Java incorporates built-in security features, including encryption and authentication. As a backend language, this technology leverages the Java Virtual Machine (JVM) to scan bytecodes for viruses and address issues before they arise.

Shopify, Instagram, Pinterest, and Mozilla have been using Python for software development for many years.

Ruby on Rails is the best backend framework for apps of any complexity

Ruby on Rails (Rails or RoR) tops the list of the best backend technologies used today. It is called "the language of careful balance." What about RoR makes the average backend developer benefit from its utilization? It is an open-source web application framework written in the Ruby programming language, which is different from others with versatility.

The core Ruby on Rails features:

  • Allows you to improve the testing process

It enables backend developers to write tests that ensure their code works correctly and catch any bugs and flaws before they go into production because of RSpec (a unit testing system for Ruby). This testing system uses a BDD (Behavior-Based Development) approach, which means that tests are written in a human-readable format that describes the expected behavior of the code. Each function in web application development is called separately and tested separately.

  • CoC (Convention over Configuration)

Ruby on Rails has a set of default configurations that work well for most applications. Backend developers don't need to spend time configuring everything from scratch. The amount of code lines is reduced.

  • Active record

A robust ORM library (Object-Relational Mapping system) provides the active record template engine. Through simplified query design, interacting with databases is much easier.

  • MVC (Model-View-Controller) architecture

This layered architecture allows the division of the code according to the functions. There are three layers – the presentation layer, the data layer, and the resource layer. The design is easily scalable for every backend developer and fully compliant with JavaScript Object Notation and eXtensible Markup Language standards.

Reliable testing
Convention over configuration
Active record
Model-View-Controller architecture
Dynamic Memory allocation (heap memory and the basic unit of the heap enables programmers to allocate memory at runtime)
Challenging study for some backend developers ( it was released not so long ago; it makes it more difficult to learn a separate Ruby on Rails code)
Execution speed

For what purposes will Ruby on Rails work?

This backend framework stands out for its fantastic versatility. Ruby on Rails suits simple mobile and web applications and apps with the most complex business logic and highly dynamic interfaces. Backend developers prioritize this web framework when the long-term project has total possible transformations or in projects with high traffic. This backend technology performs well in projects that require functional programming features.

Ruby on Rails is an absolute leader in implementing prototypes and custom databases. Extensive libraries have made the web framework the best solution for e-commerce apps. That's why the list of companies using Ruby on Rails tops Shopify.

PHP is still an in-demand technology backend

PHP (PHP Hypertext Preprocessor) is a general-purpose scripting language characterized by open source on the server side. PHP is designed to provide us with dynamic web pages.

One thing is evident so far – this scripting language is gradually losing ground. The other backend technologies, like JavaScript and Python, are much more popular than PHP, and yet, across the board, 77,5% of sites around the world still use it. In the coming years, backend developers must know PHP for web development.
