A cloud buster is a device invented by Austrian Wilhelm Reich, who claimed to be able to produce rain by draining energy from the cloud--effectively "busting a cloud." This far-fetched claim reminds me of some of the outlandish claims being made about how revolutionary cloud technology is these days. The fact is, the cloud has its place for some customers, but it is not quite the ultimate enterprise performance management (EPM)solution as it may be billed. The goal of this post is to discuss the realities, pros, and cons of the cloud deployment model that is becoming more popular in the market.
