A flexible, security-rich Java server runtime environment for enterprise applications
Overview
Robust and secure
IBM WebSphere Application Server (WAS) is a robust, enterprise-grade Java application server designed to run and manage Java EE applications at scale. It provides a secure and high-performance runtime environment for deploying mission-critical applications across on-premises, cloud and hybrid infrastructures. WAS is now part of Enterprise Application Runtimes and the JSphere Suite for Java.
Features
Enterprise Java, built to perform
Provides real‑time, application‑aware dashboards that surface performance metrics across any cloud or on‑premise environment. IBM WebSphere Application Server customers can spot latency spikes or resource contention instantly, reducing mean‑time‑to‑detect and keeping end‑user experience smooth.
Automatically scans deployed Java EE/Jakarta EE workloads and generates detailed reports on usage patterns, dependencies and modernization opportunities. IBM WebSphere Application Server helps customers prioritize refactoring effort, meet compliance requirements and justify ROI for migration projects.
Consolidates logs, metrics and health checks into a single, searchable console that integrates with CI/CD pipelines and external APM tools. With IBM WebSphere Application Server, benefit from faster root‑cause analysis, proactive alerting, and lower operational overhead for DevOps teams.
Supports both traditional monolithic J2EE apps and lightweight Liberty‑based microservices on the same platform, with selective feature activation. IBM WebSphere Application Server modernizes incrementally, reusing existing code while gaining the agility of container‑native services.
Offers a unified runtime that runs on WAS base, Network Deployment (ND), z/OS, Liberty or the WebSphere Hybrid Edition, across on‑prem, private‑cloud or public‑cloud infrastructures. IBM WebSphere Application Server protect legacy investments while moving workloads to the environment that best fits their cost, performance and regulatory needs.
Includes built‑in management APIs and DevOps integrations (Jenkins, UrbanCode Deploy, Docker, Kubernetes) to automate build, test and rollout cycles. IBM WebSphere Application Server offers faster time‑to‑market for new features and reduced manual deployment errors.
Use cases
Where Java drives business outcomes
Automatically register servers, pull the latest IBM security bulletins and alert admins when a new CVE affects any WAS instance, cutting detection time by up to 10× and helping avoid costly breaches.
Continuously discover and update every WAS/Liberty server (VM, container, ND cell), exporting the data via CSV or REST so teams always have a single source of truth for compliance and capacity planning.
Automate vulnerability detection, inventory management and patch deployment to see operational savings and ROI within 12 months, while minimizing downtime and audit risk.
Using lightweight, modular runtime which supports Java EE 8, MicroProfile, and Spring Boot, refactor monolithic apps into container‑native microservices without rewriting existing code.
