Well 3 years ago I dealt with 12 data centers spread across the globe, 8000 bare metal servers. Many giant webfarms using RHEL with DB clustering. Having to deal with SAN's and NAS.

I never said that old technologies are obsolete but, jobs for supporting them fade and we must learn to survive in the new world.
