There is, but it's also served by a saturated market full of startups that are far more innovative than IBM. And much more inexpensive. My experience of IBM's software products is that they are slightly above average, comprehensively documented, but completely out of touch with market pricing. I wouldn't say they are affordable even for fairly large enterprises -- the bang for buck is extremely poor. IBM is the choice for large, price-insensitive, risk-averse companies and bureaucracies. You can almost always do better than IBM.
