JBossESB is the next generation of EAI - better and without the vendor-lockin characteristics of old. As such, many of the capabilities mirror those of existing EAI offerings: Business Process Monitoring, Integrated Development Environment, Human Workflow User Interface, Business Process Management, Connectors, Transaction Manager, Security, Application Container, Messaging Service, Metadata Repository, Naming and Directory Service, Distributed Computing Architecture. Plus JBossESB is part of an SOI (Service Oriented Infrastructure). However, SOA is not simply a technology or a product: it's a style of design, with many aspects (such as architectural, methodological and organisational) unrelated to the actual technology.
For companies looking to modernize and unlock the value of existing on-premises systems and applications, an enterprise service bus (ESB) architecture serves as a critical foundation layer for SOA. When deployed as an ESB, the Mule runtime engine of Anypoint Platform combines the power of data and application integration across legacy systems and SaaS applications, with a seamless path to the other capabilities of Anypoint Platform and the full power of API-led connectivity.
