  2. 2. Nils Magnus Senior System Engineer with inovex GmbH lives in Munich, Germany plans, designs, consults, and actually implements scalable data center solutions for hist clientsif you are an experienced and curious engineer, looking for challenges and a good package: we hire! Member of the Board and Program Chair at LinuxTag next time in Berlin, Germany plans, organizes, and actually hosts one of Europe's most traditional conference and expo since 1996 if you are an experienced speaker with a hot subject to talk about to your peers: we want your talk in our cfpNils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  3. 3. Use the term "cloud computing"What is cloud computing, anyway? Open Stack, OwnCloud, SugarCRM, No need to confuse your engineersNils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  4. 4. Rely on feelingsRequirements are individual I believe NFS does not scale Define a spec. Challenge the competitors. Projects and vendors are usually no idiots.Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  5. 5. Do handicraft your environmentsIt's tempting to do apparently nonrecurring steps by hand for quick wins Let me just configure this interface Mandatory to automate your make world from end to endNils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  6. 6. Neglect demanding your service levelsCloud providers offer SLAs. Most clients hesitate to challenge them. Well, they have a steep learning curve with that filer, too ... SLAs are expensive. Either pay and use them or just save the money for something else Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  7. 7. Broaden the gap between developers and opsResoponsibility ping-pong and fingerpointing don't solve problems That crappy artifact doen't deploy, so what? Why don't those weirdos just run our scripts? Assign a dev the deputy admin of the week role. Send the engineers to a coding dojo.

  8. 8. Implement your individual tools for standard tasksReinvent the wheel. Not-invented-here syndrome. Those configuration management systems are all nonsense. Mine's perfect. Standardization is a strong weapon. Join forces by improving existing tools Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  9. 9. Keep a generous buffer of ressourcesUtilizations below 90% are a waste of ressources in virtualized environments Let's upgrade, we have an average load of 0.6 over the last week If your infrastructure does not scale elastically, why did you go for the cloud in the first place?

  10. 10. Set up individual maturity environmentsSoftware did work in the test and integration environment, but failed in production I was never told there could ever be more than a single database slave Configure all environments from the same sources, use the same scripts and assign comparable sizing Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  11. 11. Don't bother yourself with scalabilitySingle ressource become bottlenecks sooner than you expect We won't need multiple application servers Planning scalability might be a challenge, squashing it into existing environments is way beyond price Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
  12. 12. Try to find a technical solution for every challengeWe engineers like to play with our toys. But there might be problems, that do not need technical solutions How should we implement the SD backed, hot failover HA enhanced, LDAP driven, role-based user management for the both of us? Less is more Nils Magnus: Ten Ways To Ruin Your Cloud Experience (and how to mitigate them) LinuxCon Europe, Edinburgh, Scotland 22.10.2013
