No bottlenecks in Complex Event Processing for Real-time BI

A few BI-related posts show how CEP and CEP-related thinking is starting to trickle into conventional thinking on Business Intelligence.
First off, Intelligent Enterprise reports on some solutions to the problems of using data warehouses for real-time BI. Note that the solutions offered include Event Stream Processing (although why Forrester references ESP instead of CEP is a mystery only known to the analyst who authored this report - unless there is an expectation that just simple streamed correlations can be done in real-time analytics?) [*1].
Secondly,* Jerry Held relates in 2 articles how cloud computing will “save the day” for BI. In a nutshell, Jerry’s hypothesis is that a lack of cheap distributed computing resources are what is holding back BI, and clouds of massively parallel operations on huge datasets will be BI’s saviours. Jerry, methinks, is ahead of his time, as I can’t see data warehouses migrating to the clouds without large doses of security provisions and even cheaper bandwidth. But certainly the idea of highly parallel and scalable event+data processing operations is here today…
Notes:
[1] IE also suggests “informational fabric” for real-time BI. This is “the real-time in memory, distributed caching infrastructure embedded in a service-oriented architecture or enterprise service bus for analytic and transactional apps.” This is also CEP-relevant - the TIBCO BusinessEvents CEP platform includes such a data grid.

httppower
httppower(8) powerman httppower(8) NAME
httppower - communicate with HTTP based power distribution units SYNOPSIS
httppower [--url URL] DESCRIPTION
httppower is a helper program for powerman which enables it to communicate with HTTP based power distribution units. It is run interac- tively by the powerman daemon. OPTIONS
-u, --url URL Set the base URL. INTERACTIVE COMMANDS
The following commands are accepted at the httppower> prompt: auth user:pass Authenticate to the base URL with specified user and password, using ``basic'' HTTP authentication which sends the user and password over the network in plain text. seturl URL Set the base URL. Overrides the command line option. get [URL-suffix] Send an HTTP GET to the base URL with the optional URL-suffix appended. post [URL-suffix] key=val[&key=val]... Send an HTTP POST to the base URL with the optional URL-suffix appended, and key-value pairs as argument. FILES
/usr/sbin/httppower /etc/powerman/powerman.conf ORIGIN
PowerMan was originally developed by Andrew Uselton on LLNL's Linux clusters. This software is open source and distributed under the terms of the GNU GPL. SEE ALSO
