Docker Turns 1: What's the Future For Open Source Container Tech? 65
darthcamaro (735685) writes "Docker has become one of the most hyped open-source projects in recent years, making it hard to believe the project only started one year ago. In that one year, Docker has now gained the support of Red Hat and other major Linux vendors. What does the future hold for Docker? Will it overtake other forms of virtualization or will it just be a curiosity?"

Sun, when it still shone, used containers heavily, because they made "dedicate a machine" trivial.
You could give a product or product suite a dedicated machine, and have netstat or vnstat report on just the behavior of the one program. You could clone a copy of production for the developers to base their next release on, you could hand a release to QA to test hand have them hand it back, and finally you could hand a tested machine to production to start exposure testing.
This allowed a much more agile cycle than having to re-install a product for development, install it again for test, then fail to reproduce a problem and have tor reinstall both, and finally reinstall the "fixed" config on prod and have the bug come back! Far better quality, and far less work.
I'm a capacity planner, so I liked it because I could give a "machine" a minimum guarantee of 20% of a 64-cpu machine, and know that it it would give back the capacity it didn't use, something that "hard" LPARS can't do.
