Here be the definition:

* Highly scalable - both vertically and horizontally.
* Highly available - fault tolerant.
* Enterpise Information System (EIS) integration - legacy systems,
mainframes, databases (note more than one at a time),
* Built-in transaction management -- relying on the database for
transactions is no good when dealing with more than one database or
EIS in a single buisness transaction.
* Support for async component models -- can you write message-driven components?
* High Manageability - can you query the running software for stats
and vitals?  Can you swap out one version of a component with another
without need to bring the entire system down?
* Service Oriented Architecture (SOA) capable - webservices, CORBA, REST, RMI?
* Highly performant - can it handle 10k connections per second?
* No vedor-lockin - can an enterprise migrate to another vedor (or OSS
solution) easily?
