Platt on Web 2.0 and SOA
Microsoft architect Michael Platt has written an article for MSDN that looks at the disruption caused by the melding of SOA and Web 2.0 into what he calls "a new Software + Service model". Platt argues that users will start to require the flexibility they are becoming accustomed to in private from their enterprise IT departments, who are busy introducing SOA. He introduces the following comparison of Web 2.0 and SOA:
|Marketing Name||Web 2.0||SOA|
|UI||Ajax (Atlas)||Vista (WPF)|
|Communications||REST (ESS)||WS (WCF, Biztalk)|
|Service||SaaS||Server (Exchange, SPS, SQL)|
Platt concludes by outlining the common requirements for relationship and reputation, participative content, search and discovery, and communication and collaboration, as well as their mapping to Microsoft's offerings.
Why are they different?
SOA is about SERVICES not technologies, oddly technology companies seem obsessed with technologies rather than the "S" and "A" bits, you'd almost think they were selling something :)
