WildFly 40 Jakarta EE 11 Application Server

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Why This Image Instead of Manual Setup

Launching a raw EC2 instance and installing WildFly yourself means hours of configuration - installing Java, setting up systemd services, hardening the management console, configuring a reverse proxy, and generating secure credentials. Competing images often ship with default passwords or exposed management ports. This AMI eliminates that work entirely: WildFly 40 arrives production-ready with security hardened out of the box, so your team focuses on deploying applications rather than configuring infrastructure.

## Overview

WildFly is the widely deployed open source Jakarta EE application server and the upstream community project behind JBoss Enterprise Application Platform. It provides a fast, lightweight, fully featured runtime for Jakarta EE applications, implementing the Jakarta EE 11 platform including Servlet, Pages, CDI, Enterprise Beans, Persistence, REST, Messaging, and WebSocket. This image delivers WildFly 40 fully installed and configured as a system service, so a production-ready application server is running within minutes of launch.

## Application Stack

• WildFly installed under /opt/wildfly and run by a dedicated unprivileged service account
• Headless OpenJDK 21 Java runtime using the standalone-full profile
• Web, Enterprise Bean, messaging, persistence, and web service subsystems all available
• nginx reverse proxy fronts the application on port 80, forwarding to WildFly so visitors reach the application on the standard HTTP port without exposing WildFly directly
• systemd service starts WildFly on boot and restarts it on failure
• Server distribution lives on a dedicated, independently resizable storage volume separate from the OS disk

## Secure By Default

• Management console binds to the loopback address and is reached over an SSH tunnel - never exposed to the internet
• On first boot, a one-shot service generates fresh management and application realm passwords unique to that instance
• Credentials are written to a root-only file - no shared or default credentials ship in the image
• nginx shields WildFly from direct external access, reducing attack surface

## Ready To Use

WildFly serves the welcome page through nginx on port 80 immediately after launch. Deploy an application by:

• Uploading a WAR or EAR through the Management Console (accessed via SSH tunnel)
• Using the management command line interface
• Copying the archive into the deployments directory

## Use Cases

• Jakarta EE and REST API hosting - Teams running Java web applications who need a fully configured EE runtime without manual setup
• JBoss EAP migration - Organizations moving legacy Java EE or JBoss EAP workloads to AWS who want a familiar WildFly environment with cloud-native operational patterns
• Application server tier - Deployments behind an AWS Application Load Balancer serving production traffic
• CI/CD staging environments - Development teams deploying WARs via the management CLI on every merge, using this AMI as a consistent staging target
