Top application servers include Apache Tomcat, WildFly (JBoss), Oracle WebLogic Server, IBM WebSphere Application Server, GlassFish, Payara Server, Red Hat JBoss EAP, Apache TomEE, Jetty, and Resin. These platforms provide runtime environment support, transaction management, scalability, security controls, clustering, cloud-native deployment capabilities, and integration with enterprise frameworks like Jakarta EE and Spring. WebLogic and WebSphere are leading enterprise-grade servers for large-scale mission-critical systems, while WildFly and JBoss EAP are popular for open-source and hybrid enterprise deployments. Tomcat and Jetty are lightweight, widely used for microservices and web applications. Overall, these servers differ in performance overhead, clustering strength, cloud readiness, licensing cost, and enterprise integration depth, helping organizations run reliable and scalable business applications across modern IT environments.
