The end result of this ongoing specialization trend is that selecting the right product won’t get much easier. It used to be that when you needed a software product, you could consider the big suites or the smaller specialists, rank them according to quality and price, and make your selection based on those criteria—essentially comparing apples to apples. But with the Cloud, you have a number of specialty players who each solve different problems well, and you need to figure out the right tool—or combination of tools—for the problems you’re trying to solve.
Certainly part of this move toward specialization is a result of the emerging nature of the Cloud and NoSQL marketplaces, but the CAP Theorem won’t go away once the products mature. As a result, ZapThink expects the maturation of these markets to take a dramatically different tack than the SOA Suite market from the last decade. If you’re waiting for some big vendor suite to solve all your Cloud problems, dream on.
