The WSO2 Application Server is fully-open source and developed based on the lean, component-based WSO2 Carbon platform. It utilizes Apache Tomcat and is capable of hosting any kind of Web application deployable in Tomcat. The WSO2 Application Server also has extensive Web application and Web service management capabilities. Users can simply and effectively create, consume and manage their applications and services in a unified manner through the Application Server's "Management Console" user-interface.

Unlike many over-bloated, proprietary solutions, WSO2 has created a new platform that cuts out unnecessary layers, supporting the full WS-* stack in a simple, clean, lightweight model. It is reliable, scalable and supports secure communication and transactional integration based on the concept of loose coupling. Web applications inherit features such as authentication/authorization, user management from the WSO2 Carbon platform.

The WSO2 Application Server brings together a number of open source projects into a single, seamless, easy-to-use offering. Instead of having you to download different parts of the Apache Web services stack separately and assemble them together, WSO2 has already done that for you. With the WSO2 AS, you get a single, integrated package with lots of additional features which are inherited from the powerful WSO2 Carbon platform.

The WSO2 Application Server is an on-going project. It undergoes continuous improvements and enhancements with each new release, to address new business challenges and customer expectations. WSO2 invites users, developers and enthusiasts to get involved or get the assistance from our development teams at many different levels through online forums, mailing lists and support options. We are committed to ensure you a fulfilling user experience at any level of involvement with the WSO2 Application Server.
