Chose Red Hat JBoss Enterprise Application Platform
Jboss supports JEE standards and provides features like high availability, clustering, hot deployments, configurable features. you can quickly add or remove needed features and cut jboss footprint and reduce boot time.
JBoss EAP is subscription based/open source platform. It's very reliable and great for deploying high transaction Java based enterprise applications. It integrates well with third party components like mod_cluster and supports popular Java EE web-based frameworks such as Spring, Angular JS, jQuery Mobile, and Google Web Toolkit.
As the version supported by Oracle we have an extensive documentation, the Oracle GlassFish server online documentation library, patches ,and support from the supplier.
Ease of use through the administration console.
Integration with the NetBeans development interface.
MOD_CLUSTER integration. JBoss EAP integrates pretty well with mod_cluster. This is an intelligent load balancer especially useful in highly clustered environments.
Supports enterprise-grade features such as high availability clustering, distributed caching, messaging etc.
Supports deployment in on-premise, virtual and hybrid cloud environments.
One of the areas where we found Glassfish adaptation difficult for our company was the lack of documentation and community forums covering important issues.
We ran into a roadblock with OAuth 2.0 implementation and did not get great support on that issue.
JBoss EAP is lightweight and doesn't really consumes much physical resources. It's high performing and suites well for high transaction Java enterprise applications. The out of box performance settings are not really great and you will have to configure the settings to suite your environment to leverage it's full benefits.
Jboss EAP is easy to deploy and configure. This lead to lower cost and faster delivery.
Even though we have large number of machines running JBoss, we have only two Jboss Administrators. It doesn't requires too much administration and maintenance on daily basis and reduces number of administrators required for large implementations.
