Dain Hansen just posted a blog Hotter than a Hedge Fund: SOA Integration. Although we don't know whether a hedge fund manager John Paulson used SOA to short sub-prime mortgage-backed securities to grow his fund by $15 billion and to make $4 billion in 2007 SOA is still hot. Not only will you reduce your operating expenses using enterprise service bus (ESB), but you'll also STREAMLINE your business operations using ESB federations - networks of ESBs.
How to look at the ESB federations?
From the conceptual architectural perspective, ESB federations are a new language which IT will learn to speak. ESB federations will transform IT infrastructure into an integral part of a business structure. The business structure of a successful enterprise is continually growing, organically, or, by mergers and acquisitions. Therefore, in order to keep up with the business expansion, the IT infrastructure needs to be expandable without breaking already existing parts. If you plan from the start to use ESB federation for future IT expansion, the existing IT components will stay in tact when new ones are added.
The way to achieve extensibility is to use open architecture with abstraction layers. You can look at each ESB as a building block of the extensible ESB federation, a network of ESBs. Continuing this analogy, you can look at the first ESB to which the client application connects as the interface abstracting the client from the implementation of the rest of the ESB federation.
Moreover, because in the information age an ESB federation is a business enabler, all of our roads cross here - dev, arch, IT and exec.
