Many of today’s applications must process enormous volumes of data while providing instantaneous responses.Traditional blocking architectures often struggle to meet these demands, leading to sluggish performance and poor user experiences. Reactive programming is a coding paradigm that can help address these issues by using asynchronous, non-blocking operations to change how systems are built.

This blog posts explores the core principles, advantages and best practices of reactive programming in Java to help you create scalable, resilient and high-performance applications. 

Over the past decades, the technology landscape has undergone relentless change, with innovations rapidly reshaping how applications are developed and deployed. In such a fast-moving environment, few technologies have demonstrated true staying power. Yet, Java has defied the odds. As we mark 30 years of Java and 25 years of enterprise Java, it’s evident that these platforms haven’t just endured but have thrived—constantly evolving, adapting and proving their enduring value to developers worldwide.

Git, the weirdly named version control system developed by Linus Torvalds,  is an amazing tool for developers, and us Java developers are no exception. While most of us are familiar with the basics like git commit, git push and git pull, Git has a lot of lesser-known features that can significantly improve your workflow. In this post, we’ll explore five hidden Git tips tailored specifically for Java development. These tips will help you manage your codebase more efficiently, debug issues faster and collaborate more effectively. Let’s go!

Companies sometimes contemplate migrating their enterprise Java applications to a different runtime to optimize costs, benefit from greater technical support, achieve better performance, scalability or new functionalities. However, when it comes to taking active steps towards implementing an alternative application server, many decide not to proceed. A recurring concern for multiple companies is whether such migrations can be done securely, without compromising data integrity or compliance with stringent regulations.

So, are application server migrations secure? How can teams ensure the right robustness and resilience measures are in place? Let’s dig in the world of runtime cybersecurity and migration planning.

May 2025 marks a monumental milestone in software development: Java turns 30. The impact of this language on the technology landscape is undeniable, forming the backbone of today’s digital world. Its anniversary is a celebration of the code as well as the innovation, adaptability and thriving global community built around Java. The return of JavaOne, which used to be the ultimate gathering for the Java community, offers a perfect moment to reflect on the technology's legacy, its continued relevanceand its achievements. 

JavaLand 2025 is happening from April 1-3, 2025, in Nürburgring, Germany, and Payara will be there! If you’re into Java, want to learn about the latest tech, or just want to connect with fellow developers, don’t miss this event. Our team of Payarans will be sharing practical insights and real-world use cases that you can start using right away to enhance your Java and Jakarta EE projects.

Today’s developers are tasked with building systems that are not only robust but also agile enough to keep up with evolving user demands. Microservices have emerged as a favorite among engineering teams to address these issues because they decompose applications into independent, manageable services. But how do they work, specifically? What can microservices architectures offer? And how can you adopt this paradigm within your application development team? 

If you want to know what microservices architectures can bring to your team, you’re in the right place. In this blog, we discuss the top benefits of microservices and how developers can easily embrace this approach. 

After a long hiatus, the premier conference for Java developers worldwide, JavaOne, is making a grand return. This year's event is even more special as it coincides with the 30th anniversary of Java. Of course, our Payarans will not miss this event, and we are thrilled to exhibit and present at JavaOne 2025! Mark your calendar and join us from March 18–20, 2025, at Redwood Shores, CA, U.S.

One of the largest and longest-running Java conference, Devnexus 2025, is just around the corner and our Payarans are ready to bring cutting-edge insights to the event. If you’re a Java developer eager to explore the latest technology advancements and industry trends, this is an event you don’t want to miss!

Enterprise Java development has evolved significantly from the days of J2EE, which moved to the Eclipse Foundation as Java EE and eventually became Jakarta EE. This progression has provided developers like you and me with a comprehensive platform for building reliable, scalable applications. Let's explore 10 ways Jakarta EE 11 streamlines enterprise development, with special attention to the newly released Jakarta Data 1.0 specification.
