In the world of enterprise application hosting, few servers have gained as much attention as WildFly. Known for its simplicity and powerful capabilities, WildFly is a core player in web and enterprise applications. As an open-source server, it has evolved into a reliable tool for deploying Java-based applications. Let’s dive into what WildFly is, what it’s used for, and why it might be the right choice for your business.
What is WildFly?
WildFly, originally known as JBoss, is a modular and lightweight Java-based application server that implements Java EE specifications. Released under the GNU Lesser General Public License (LGPL), WildFly is freely available for use and distribution. This flexibility allows developers to build, deploy, and manage applications efficiently while minimizing technical burdens.
For businesses, WildFly offers a streamlined platform that reduces development time, improves resource management, and saves costs—all while providing the tools needed for modern software architectures.
WildFly vs. JBoss: What’s the Difference?
While WildFly and JBoss are often confused, they are not exactly the same. JBoss originally referred to two versions: JBoss AS (Application Server) and JBoss EAP (Enterprise Application Platform). The open-source community used JBoss AS for free development, while JBoss EAP was a commercial version that required a paid license for production use.
In 2012, the open-source JBoss AS was renamed WildFly, marking the end of JBoss AS 7. Though the JBoss EAP is built upon the WildFly source code, they differ in terms of security features and functionalities. Thus, while WildFly is the community-driven, free version, JBoss EAP is the commercial counterpart with additional enterprise-grade features.
What is WildFly Used For?
WildFly is a versatile platform designed to host Java-based enterprise applications. It’s particularly well-suited for deploying web applications, microservices, batch processing, and messaging systems. Here’s how WildFly stands out in modern software development:
- Microservices: WildFly excels at managing microservices-based applications. It provides essential features like load balancing, clustering, and security, which are critical for scaling applications and ensuring reliability.
- Web Applications and RESTful Services: WildFly is also a reliable choice for running web applications and RESTful web services, ensuring high availability and performance through its robust clustering capabilities.
- Testing and Development: Developers often use WildFly for local development and testing before deploying applications to production environments. It simplifies the development cycle and enhances efficiency.
Key Benefits of Using WildFly
1. Saves Time and Resources
WildFly optimizes memory management through intelligent subsystems that can be easily configured. This modular approach allows developers to add or remove components as needed, making the server highly customizable for specific requirements. Additionally, when working in domain mode, WildFly organizes configurations for multiple machines in a single, unified file, which enhances consistency across deployments.
2. Open-Source Freedom
Being open-source, WildFly can be used, modified, and distributed freely under the LGPL v2.1 license. This openness fosters innovation, allowing businesses to create unique technologies and tailor solutions to their specific needs. For startups and enterprises alike, this flexibility can lead to cost savings and faster development cycles.
