Doing Ops big time

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.

  • Versioning
  • 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 ….

That other dude sitting at another table: jejejeje!!! What a waste! Weil they were doing that, I was making money.

Sing along!!

Real Big Ops manage their own datacenters! Yeah yeah yeah

The even build their own datacenters! Wow wow wow

That is just so agile and cool and hey!

you even get to choose the colour of you cables!  … *LOL*

Ok, if you really need your own datacenter, then you are delivering an “über” global service.

„With NTTA, we can focus our resources on developing software and serving our valued user community rather than on building, financing, and managing an in- house IT infrastructure team.“  Lee Mighdoll, Vice President of Engineering and Operation, Twitter

… and the author isn’t getting any money (at this moment) from NTTA.

“Not even the best OpsTeam in the world (including everything outside USA) using the best tools they get/implement, can warranty availability and efficiency, if they must run crappy applications … it just won’t work.”  The author, by himself.

pure ITIL ~ high Process compliance ~ standardisation ~languorous and slow reaction times ~ sluggish                          |

|-à balance ~ Enlightenment ~ Nirvana

No Process compliance ~ low level standardisation (if any) ~quick implementation and fast reaction times ~ mayhem      |

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.”

A high available fault tolerant system must obey the following rules:

  1. Isolation
  2. Concurrency
  3. Failure detection
  4. Failure identification
  5. Stable storage
  6. Live Code Upgrade

Andrew: Who rolls back?

Guys: Hands up … yeah we roll back! 😉

Andrew: Screw that, roll forward.

Guys: Why?

Andrew: Because I roll forward, dog!

If you are agile (~fast!) enough to do CLD, then you’ll never need to roll back.

    … ist auch ohne Popcorn und Cola spannend. Zumindest werden ein paar allgemeine Ideen vorgestellt und teilweise vertieft.
