Jetzt geht es darum, wie wird Ops bei manchen Großen gemacht. Bitte nimmt euch die Zeit, holt euch Pop Corn, Cola und eine Decke und schaut euch diese Videos mit euren liebsten an, die/der könnte nebenbei z.B. häckeln.
- OPTIMIZE EARLY
- automation, automation, automation
- use a configuration management system (keep it agile! – the process)
- EVERYTHING WILL FAIL, “und das ist gut so” , so be prepared
- Messure/Instrument a lot, if not everything
dude 1: Whatz up! Dude! I just came from our own brand new datacenter.
dude 2: What!? Dude, your company builds its own datacenters! Wow! That’s totally cool, dude!
dude 1: Yeah dude, and we have all this racks and cables and ….

Real Big Ops manage their own datacenters! Yeah yeah yeah

“Nirvana is the supreme state free from suffering and individual existence. It is a state Buddhists refer to as “Enlightenment“. It is the ultimate goal of all Buddhists. The attainment of nirvana breaks the otherwise endless rebirth cycle of reincarnation. Buddhists also consider nirvana as freedom from all worldly concerns such as greed, hate, and ignorance. No one can describe in words what nirvana is. It can only be experienced directly.”
