Rich Enterprise Applications (REA)

Move over RIA, there's a new acronym that be is stressing on their new revised JackBe site and its foundation is built upon the Web, SOA and AJAX. Like Web 2.0 is an evolution of the Web1.0, REA is the evolution of rich Internet applications which are fine for consumer facing sites, but not really ready for real enterprise, mission critical applications.

From Wikipedia:

"Rich Enterprise Applications (REA) creates a new class of enterprise Web 2.0 applications. REA solutions leverage the usability and increased functionality of RIA applications and extends their reach beyond the browser and into the organization’s Service Orientated Architecture(SOA) assets.

REAs leverage an organization’s investment in SOA with enterprise Web 2.0 technologies that enable new business and application models such as Software as a Service (SaaS), enterprise mashups, next-generation portals, and browser-based deployment of enterprise applications – all with robust scalability, security, and desktop-like interactivity on the client side utilizing AJAX."

It continues and notes that just because an enterprise has AJAX and SOA, doesn't neccessarilly mean they have an REA. For the enterprise, there are three additional components RIA does not require but REA does.

1. User-driven Integration
2. Service Governance - "I think this is the real differenciater between RIA and REA."
3. Enterprise Grade Communication Channel

Interview with Dan Malks, Deepak Alur, & John Crupi of JackBe

http://sys-con.tv/read/239153.htm Live from JavaOne 2006 in San Francisco By: SYS-CON TV Jun. 21, 2006 12:00 PM I liked the fact that Danny Malks mentioned how JackBe is moving towards "lightweight" platform solutions direction with r egards to the convergance of SOA and the client while utilalyzing AJAX technologies. Sounds like a software model that could help other independent software vendors (ISVs), service providers and enterprises deploy their services exposed by their SOA as software as a service (SaaS). In addition, to not only creating meaningfull mashups, but provide a lightweight admin platform to regulate those atomic messages. Interesting listen from the former Sun team who brought us the J2EE bible. Only thing I noticed is that I had to quickly turn down my volume when John Crupi spoke a couple of times. He's so loud. I wonder if he's always so loud? Web 2.0, Mashup, Enterprise 2.0, AJAX, SOA, Composite Applications, Platform, Framework, l

DC Metro Police

This happened to one of my best friends who just so happens to be of Pakistany origen. By the way he actually was born and grew up in OHIO. Way to go Metro and DC Police. "Last week I entered the metro with my wife. As usual, we were in haste and wanted to just board the train by making our way through the crowded gates. I have a Smart-card and replenish it once every 2 weeks. As i walked through the gate, i had -$0.30 on my card. If anyone has a Smartcard, they know that the card lets you be negative to a certain amount, but when you refill the card you have to make up the difference. That is a benefit of the Smart Card. But Officer BF Johnson didn't think so. He stopped me in my tracks, ordered me to approach him. He then ordered me to hand over my license and called the station to check for any suspicious (Obviously terror-related) activity from my end. He was telling me "you are riding on a negative balance, you are stealing from the metro". Yeah, lets call th
