Cloud Event Processing vs Event Cloud Processing?

Interesting to see the huge interest in Cloud Computing. David Luckham’s complexevents.com just referenced one of several recent Infoworld articles and blogs that attempt to define the term. Another compares the buzz to past excitements - remember Application Service Provider and Software As A Service? But Clouds are of direct interest to the Complex Event Processing community: CEP is, afterall, about processing clouds of events.
Just to be clear…
1. Complex Event Processing is another term for Event Cloud Processing: processing clouds of events, which may include multiple event streams of course.
2. Cloud-based Event Processing is where some event processing application is put into a closed / corporate, or public / distributed, cloud computing environment. Event latency and event store latency will be major considerations here.
It’s interesting to compare “cloud computing” with more conventional advances in distributed corporate IT. TIBCO BusinessEvents, for example, provides an “event cloud processing” (aka CEP!) platform that includes both the event processing and data cache agents. Will this ever be requested, or offered, as a cloud service by TIBCO or a TIBCO partner? Possibly. Application domains for this might be the interface between the social network and commercial IT worlds - consider things like medical drug programs, healthcare data collection, and so forth. We’ll let you know if and when it happens…

httppower(8) powerman httppower(8) NAME
httppower - communicate with HTTP based power distribution units SYNOPSIS
httppower [--url URL] DESCRIPTION
