Enterprise Java applications power global commerce, healthcare, government and countless other industries. These systems must be scalable, secure and resilient – requirements that exceed what a simple web server can provide. That’s where enterprise Java application servers come in. In this short guide you’ll learn what enterprise Java application servers are, how they work, why enterprises rely on them, and why Payara Platform is the leading choice for modern Jakarta EE and MicroProfile workloads.

If you’re a Java developer, you probably feel sandwiched between frameworks nearing end-of-life, fresh Log4j headlines and endless security patch cycles. Fixing one vulnerability only to uncover another can feel like running on a treadmill.

You've probably been in that hallway conversation (or Teams/Zoom meeting) where DevOps, SRE and Platform Engineering all get thrown around. Sometimes these words are used interchangeably, as if they were synonyms. Sometimes they indicate different aspects, but nobody really agrees on what they are.

If you can relate, know that you're not alone. That's why we decided to walk through the core differences (and overlaps) of what each term means for us at Payara. 

When the SIFMA Foundation needed to modernize its aging financial education platform used by thousands of students, it turned to Payara Platform Enterprise for a scalable, reliable Java-based solution that could run seamlessly on IBM Advanced Interactive eXecutive (AIX) systems. The result: boost in user capacity per machine, streamlined deployments, and the flexibility to innovate continuously. With Payara’s responsive enterprise support and robust middleware technologies, SIFMA transitioned its mission-critical system to a modern architecture that is empowering the application and the organization to grow its impact, serve more students, and deploy updates confidently and efficiently.

Enterprise Java has powered backend systems and key applications for three decades, evolving steadily alongside application architecture trends, from on-premise monoliths and service-oriented architectures to today's cloud-first containerized microservices. Currently, developers can typically  choose from three key enterprise Java frameworks: Jakarta EE, Quarkus and Spring / Spring Boot. 

In this post, we take a practical look at two major enterprise Java frameworks: Jakarta EE, the continuation of the long-established Java EE/J2EE standard and Quarkus, a newer framework that is growing in popularity. 

Last week, we announced the new edition of the Virtual Payara Conference, going live on Tuesday the 8th of July (REGISTER HERE), where we'll help you discover some practical strategies for your Java journey.

The new edition of Virtual Payara Conference is coming on the 8th of July 2025 and this time it's all about discovering practical strategies for your Java journey – whether you use Jakarta EE, Spring, or Quarkus! 

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!
