- Unlike Java EE app servers, Fabric3 is designed with integration in mind as opposed to autonomous (and often monolithic) applications. Fabric3 assembles composite is used to assemble applications from loosely-coupled distributed services.
- Dependency injection frameworks such as Spring and Guice assemble local application components; Fabric3 extends assembly from local to distributed services.
- Unlike Enterprise Service Buses (ESB), Fabric3 is not based on a proprietary programming and integration model that routes all communication through a messaging abstractionrouting and transformation framework. Instead, Fabric3 relies on the SCA standards to wire application components directly or through typed channels without the complexity and overhead of an intermediary.
- Dependency injection frameworks such as Spring and Guice assemble local application components; Fabric3 extends assembly from local to distributed services.Fabric3 does not compete with messaging middleware (MOM), but often uses it for remote communication between services.
- Fabric3 does not replace web services but can be used to expose RESTful resources and WS-* endpoints to external clients.
