Don Burleson posted an interesting article today on Oracle virtualization and makes the point that it is leading us into the “second age of mainframe computing.”
It’s back to the future for the Oracle database world. The inefficient one server/one database approach of 1990s client-server technology is long gone and Oracle shops are now re-consolidating their data resources, moving back to the mainframe-like centralization of the 1980s. . . .
Moreoever, he says that this trend is bad for the DBA job market:
Server consolidation is bad for the DBA job market because one of the main reasons for consolidating hardware resources is the savings from reducing DBA staff. A typical shop can save a million dollars a year by removing a dozen DBAs.
Add virtualization to the list of DBA complaints. . .
