How GlassFish compares against other solutions:
-
WildFly
Provides a stable and reliable foundation. Long-term support is available exclusively through migration to JBoss. Backward compatibility is not guaranteed, and resolving issues may require internal technical intervention
-
WebLogic
Robust and feature-rich, but associated with significant overhead and licence cost. Lags in supporting new Java versions and adopting new Jakarta EE versions.
-
WebSphere
Reliable and feature-rich, though it involves huge overhead and significant licensing fees. It's slow to support new Java and Jakarta EE versions.
-
Spring Boot
Well-suited for greenfield development; however, migrating legacy Java EE applications may resemble a complete rewrite due to significant architectural differences.
-
Apache TomEE
Lightweight in design, but may become restrictive when scaling or managing complex enterprise workloads. Lags in adopting new features and updated Jakarta EE versions.
-
Quarkus
Popular for container-native applications, well-suited for greenfield development. Extremely fast startup, great developer experience. Handling legacy monolithic systems can be difficult. Migrating older Java EE applications is feasible, though often complex.
GlassFish is flourishing at the eclipse foundation
The Eclipse GlassFish application server has been a compatible product for every Jakarta EE release, and it has very deep roots in the Java world.
Today, the GlassFish server is flourishing as an opensource project at the Eclipse Foundation, it’s ready and reliable for production deployments, and is being updated to strengthen its merits as an application server.
The OmniFish team is devoted to improve GlassFish and regularly contributes to the GlassFish project at the Eclipse Foundation to fix defects and vulnerabilities, improve production performance, and introduce new features.
