Rather, I agree that people simply aren&#39;t used to designing applications with this types of building blocks in mind.<br /><br />Case in point: you have a need to run in multiple datacenters due either to geographic locality or purely for high availability reasons. The CAP theorem says that you can&#39;t guarantee availability and consistency at the same time here; many of the cloud building blocks don&#39;t give you strong consistency guarantees (e.g. transactions), but you&#39;ve already gone down that road anyway once you&#39;ve built a distributed system (assuming that availability is more important that strict consistency, which it usually is).<br /><br />I think this will eventually sort itself out in the market; vendors and software companies that use these techniques will enjoy faster times to market and economies of scale and hence will drive out those who don&#39;t understand these techniques through pure economic Darwinism.
