In a Wall Street Journal article this morning about Microsoft's move into SaaS, Mr. Esat Sezer, the CIO of Coca-Cola was quoted:
Offloading the software to Microsoft will let the bottler focus on its core business, he said. "We don't see running the servers and networks and software as a differentiator versus our competitors," Mr. Sezer said.
In a nutshell, Mr. Sezer has said (and the WSJ reporter has probably paraphrased) exactly what the CPM message has been all along -- you do not gain competitive advantage by running complex software systems, unless your business is running complex software systems.
Construction companies, architecture firms, developers, and government agencies, all have more pressing priorities to attend to than to apply the latest Microsoft Service Pack to their database cluster. This, dear readers, is why SaaS is the future in the construction industry.
