WildFly, formerly known as JBoss Application Server, is an open source Java EE application server. Its primary goal is to provide a set of vital tools for enterprise Java applications.
According to the Jakarta EE 2020/2021 survey, WildFly is head and shoulders above in the recent application servers and in the rating categories. Here are some of the reasons why:
1. Save time with faster development
WildFly supports the newest standards for REST-based data access, including JAX-RS 2 and JSON-P, and because it's building on Jakarta EE, which provides rich enterprise capabilities with ease of use of frameworks that eliminate boilerplate and reduce technical burden.
The quick boot feature of WildFly, integrated with the easy-to-use Arquillian framework, allows for test-driven development using the actual environment in which your code runs. This test code is separate and deployed alongside the application, where it has full access to server resources.
2. Powerful but simple to use
WildFly configuration setup is centralized, simple, and user-focused.
The configuration file—organized by subsystems—is easy to understand and has no internal server wiring that will be exposed. All management capabilities appear in a unified manner across all forms of access. These include a command-line interface, a web-based administration console, a native Java API, an HTTP/JSON-based REST API, and a JMX gateway. These options allow for custom automation using the tools and languages that best suit your needs.
3. Modular and lightweight
WildFly does classloading right. And it does it smoothly. It uses JBoss Modules to provide true application isolation while hiding server implementation classes from the application and only connects to JARs that your application needs. Appearance rules have sensible defaults but are usually customized. The dependency resolution algorithm means that classloading performance isn't affected by the number of versions of libraries you've got installed.
In WildFly base, they've developed runtime services to attenuate heap allocation using standard cached indexed metadata over duplicate full parses, which reduces heap and object churn. One hundred percent of the administration console is stateless and purely client-driven. It starts immediately and requires zero memory on the server. This integrated configuration enables WildFly to run with stock JVM settings—even on small devices while leaving more headroom for application data and supporting high-level scalability.
4. Save resources with efficient management
WildFly takes a more aggressive approach to memory management and relies on pluggable subsystems, installed or removed as required. Subsystems use smart and intelligent defaults but can still be customized to best suit your needs. When working with domain mode, all participating servers' configuration is laid out in a well-organized, consistent manner within the same file.
5. Leverage open source
WildFly is an open source community project and is out there to be used and distributed using the LGPL v2.1 license, which means it's available for you to download and use for whatever you need. This allows organizations to develop unique new technologies and federates the world of technology to help successful startups to spring up anywhere.
