Constraining everything in development and testing is database size. Storage is a bottleneck, and while faster SSD/Flash is available, it is still too expensive due to the size of many databases, especially in DEV and TEST. More to the point, it takes a lot of time to push terabytes around, and time itself is expensive. The old joke about "good, fast, and cheap -- pick any two" is so true with data.
Providing full databases for each developer or tester on each task of each project seems unrealistic, when each copy might require terabytes of storage, so for decades everyone has limited themselves to working in shared dev/test environments that are refreshed only every few months, where conflicts occur, quality suffers, and things move slowly.
Come learn why data virtualization is the solution to a problem everyone knows.
Good, fast, and cheap -- have all three with data virtualization. Be able to clone data quickly, and remove the biggest constraint to development and testing.
