What programming languages does Twitter use, and is Java among them?

Twitter has become a very large enterprise, especially after Elon Musk bought it. So, it became natural to ask which languages were used for its development. Building scalable apps is a goal for anyone who wants to find Java developers to hire.

So it comes naturally to ask why to hire a Java developer if this programming language needs to be revised.

Why did Twitter change Ruby on Rails with Java?

Before you look for a Java developer for hire, you need to know what made Twitter change Ruby with Java. Java was chosen as the language to replace Ruby on Rails by Twitter for a variety of reasons. 

The company discovered that its Ruby on Rails application’s performance was insufficient to handle the high volume of queries as Twitter expanded and the site’s traffic rose. This was one of the primary reasons why the company decided to shut down the service. In addition, as the number of people using Twitter expanded, the platform’s ability to scale needed to be improved. Additionally, they have a great deal of data, and at the time, Java offered superior support for real-time data processing and large data.

Java, on the other hand, is a platform that has been around longer, is more reliable, and is better equipped to deal with high traffic and enormous amounts of data. Additionally, the Java developer community is huge and very active, making it much simpler to discover developers with the requisite skills and resources.

Java was a solid choice for the microservices architecture that Twitter adopted, and Java was also a smart choice for Twitter itself. Since Java had superior support for enterprise-grade features, such as improved threading and memory management, both of which were necessary components of a microservices design, Java was chosen.

In a nutshell, Twitter switched from Ruby on Rails to Java because Java offers improved performance and scalability, has a strong developer community, and is better suited for the company’s demands in terms of real-time data processing and big data.

Twitter’s primary language is Scala, so why find Java coders for hire instead?

Twitter uses Scala, which is a programming language that runs on the Java Virtual Machine (JVM) and is strongly influenced by Java.

Scala is often used in big data and distributed systems because it is well-suited for these types of applications, and it provides a more expressive and concise syntax than Java. Additionally, Scala also has built-in support for functional programming, which can make it easier to write concurrent and parallel code. This is useful for big data processing and distributed systems that need to handle high volumes of data and many concurrent operations.

Twitter adopted Scala and JVM-based technologies to leverage its existing Java infrastructure, developer base, and libraries but also gain the benefits of a more expressive and performant language like Scala. Scala’s ability to handle concurrency and high-scale workloads helped Twitter’s engineers to build distributed and fault-tolerant systems for real-time processing and analytics of high-volume data streams.

Scala was a great fit for Twitter’s architecture because it was designed with scalability and concurrency in mind, and it can handle the high volume of requests that Twitter receives. Additionally, the company’s engineers were already familiar with Java, which made the transition to Scala relatively smooth.

It’s not only Twitter – many huge online services use Java as a weapon

If you wonder why many huge companies hire a Java coder for their server-side operations, we will tell you now.

The following is a list of some of the many significant organizations that utilize Java as their primary programming language:

Amazon: Amazon’s backend systems, such as its e-commerce platform and its recommendation system, are powered by Java. Because of its reliability and performance, as well as the enormous number of developers that use it, Java is an excellent choice for developing and maintaining large-scale systems.

Google: Java is utilized by numerous apps developed by Google, including the Android operating system and the Google Search engine. Java’s performance, security, and scalability are the primary reasons behind Google’s use of the programming language.

Netflix: Java is used throughout Netflix’s infrastructure, including its backend systems and mobile applications for Android and iOS. Due to its high performance and scalability, Java is an excellent choice for Netflix to use to manage the significant amount of online video streaming traffic it receives. In addition, Netflix possesses a group of talented Java developers, so the acquisition was an obvious choice for the company.

Spotify: Java is the programming language used for Spotify’s backend operations and its mobile applications for Android and iOS. Building large-scale systems that need to manage heavy traffic and enormous amounts of data is a task that lends itself well to Java’s capabilities.

Uber: Java is the programming language used for Uber’s backend systems as well as its mobile applications for Android and iOS. Because of the wide availability of rich open-source frameworks, such as Spring framework and Hibernate, Java is an excellent choice for developing large-scale systems that must manage high levels of traffic and significant volumes of data.

These businesses frequently go with Java since it is a well-established and reliable platform that delivers satisfactory performance levels and can be easily scaled. Additionally, the Java developer community is huge and very active, making it much simpler to discover developers with the requisite skills and resources.

Because it supports enterprise-grade features like threading and memory management, the language is also famous for usage in enterprise-grade systems. It is one of the reasons why the language is so popular. In addition, the Java ecosystem gives users access to a wide variety of open-source libraries and frameworks, which speeds up the application development and deployment process for businesses.

Summary

It becomes evident why Twitter has chosen Scala and Java ahead of Ruby on Rails. While the latter offers some unique functionalities, the enterprise-level scaling is what makes the JVM a solid reason why Twitter would rather hire a Java developer than a Ruby programmer in 2023.
