Test Environments and Test Data in big enterprises. Scaling from small to huge is as challenging as building the product itself. Spinning new environment on the fly that includes 100's of subsystems, creating an anonymized subset copy of production on demand or generating enough synthetic data on the fly are huge challenges even though some of the tooling exists. A related problem related to data creation and subsetting is that one person (and practically nobody) knows the entire data relationships between subsystems, but you still need them to create your data.
