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.

With Jakarta EE 11 now officially released, you are likely eager to explore its new capabilities but setting up your first application may take longer than you want. That’s where the latest version of Payara Starter steps in, giving you a fast, hassle-free way to get a fully functional Jakarta EE 11 project up and running. Read more to learn how!

Cloud adoption has transformed how developers build and scale applications, but it also brings new challenges in controlling costs. As cloud bills grow alongside usage, designing cost-efficient cloud architectures becomes essential for developers, DevOps specialists, architects and team leaders.

This post explores key strategies for optimizing cloud expenditure and align it with actual needs without incurring cloud wastage spend.

As a Java developer, you may not control runtime support contracts, but what you can do is help your team stay ahead of platform shifts that impact stability, compliance and portability. And here’s a big one:

📢 Red Hat officially announced that JBoss EAP 7 reached the end of Maintenance Support and entered Extended Life Support Phase 1 (ELS-1) on June 30, 2025.

This marks the beginning of a gradual end-of-support timeline that affects all Java EE 8 applications running on JBoss EAP 7.x. The change was confirmed by Red Hat as part of its product lifecycle updates, and it’s a clear sign that organizations need to plan for what's next. If your manager asks you for an overview on what's happening and the options at hands, this blog post is for you: we summarized everything you need to know and what you can do for your Java EE 8 applications.

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. 

Kubernetes, also known as K8s has become the de facto platform for orchestrating modern microservices architectures, promising resilience, scalability and faster deployment pipelines for Java applications. But for many developers, that promise often hides a thorny reality: Kubernetes is powerful—but also painfully complex.

The August 2025 release brings important security fixes and stability improvements across the Payara Platform. This month's releases include Payara Platform Community 6.2025.8 and Payara Platform Community 7.1 Alpha4, Payara Platform Enterprise 6.29.0 and 5.78.0, with a focus on addressing critical security vulnerabilities and enhancing platform reliability.

Many enterprise Java application developers are facing the same challenge: handling the many legacy systems used by their organizations. Modernizing these is critical to improving scalability, performance and security. Yet, many teams are still supporting workloads based on Java SE 8 or earlier versions, despite newer versions and modern frameworks offering significant advantages. This aversity to refreshing such applications stems precisely from the importance these pieces of software have within an organization, as their disruption can considerably impact business operations.  

This blog is your practical guide to successfully navigating that shift: from evaluating legacy codebases to leveraging cloud-native architectures, CI/CD pipelines and runtime tools to futureproof your enterprise Java applications while streamlining key modernization efforts.
