TIBCO ActiveMatrix and BusinessWorks
TIBCO (The Information Bus COmpany) has been around for more than 20 years in various
forms, and its integration story goes back for most of this time. Its integration products are
well known and popular, and companies such as Delta, Lockheed Marin, Lufthansa, MLB,
Qualcomm, Reuters, Seagate, and more use them.
TIBCO's ESB is ActiveMatrix Service Bus, which allows you to develop, manage, and mon-
itor web services in Java and .NET. BusinessWorks is a related product that handles orches-
tration of web services, employing SOAP/HTTP or SOAP/JMS.
ActiveMatrix ESB uses a grid-based architecture, which allows you to scale both up and out
dynamically at runtime and on commodity hardware.
Event framework
The primary idea that distinguishes TIBCO's ESB from other implementations is that it is
built on an eventing framework. In JBI-based ESBs, messages enter the bus and are sent via a
delivery channel to the normalized message router for immediate delivery to one of the other
components defined in the service unit.
But in TIBCO's ESB (which does not implement JBI), messages instead enter an “event
cloud,” which is essentially a database that stores message state, allowing for message frag-
ments to be used within an event framework. This allows for a very loosely coupled runtime.
Grid-based architecture
The grid-based architecture featured in TIBCO's ESB means that you can use commodity
hardware but still enjoy reliability, recoverability, and self-healing via other nodes on the grid.
The ESB can also be clustered and load-balanced, and it does not require an application server
to run.
