visited one telco that said, "we like ESBs so much that we have five different ones!" This of course begs the question - which one is
My guess is this is more a byproduct of politics and procurement than technical design, however, the point is still a good one. In reality, I think there should be several different buses: The ESB An MSB (management services bus) for monitoring/administration An ELB (error & logging bus) An ARB (archive & reporting bus) feeding the datawarehouse - replaces ETL etc. -- email: [EMAIL PROTECTED] phone: 425.679.3533 office: 3/4320 IM/MSN: [EMAIL PROTECTED] expedia blog: http://confluence/x/EwM <http://confluence/x/EwM> <http://javaland1/confluence/display/people/Writing+Wrongs> "The 'S' in SOA means service, not server; 1 service != 1 server." ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Gervas Douglas Sent: Thursday, April 05, 2007 6:00 AM To: [email protected] Subject: [service-orientated-architecture] DSB - a new acronym No, it is not necessarily the favourite acronym of a dyslexic Aston Martin owner. Here is an extract from an e-mail Miko kindly sent me: "I'm seeing increased sophistication around lifecycle and federation issues in Governance and some interesting insights about whether the Enterprise Service Bus is truly a ubiquitous pattern or whether we are seeing the "Domain Service Bus" (DSB anyone?) winning the day. I visited one telco that said, "we like ESBs so much that we have five different ones!" This of course begs the question - which one is actually the " Enterprise " Service Bus. The answer? None of them!!! Five ESB products and no ESB. This is much more common than you would think. I'm happy to chat about this observation if you're curious." I guess there is a natural hierarchy of confusion with these buses. Would someone like to take up Miko´s invitation to chat about DSBs in this forum? Gervas
