DevOps is not a set of tools, nor is it just automating deployments. It is a set of principles that benefit anyone trying to improve a complex process. This talk will present the DevOps principles in terms that apply to all system administrators, and use case studies to explore their use in non-developer environments. Thomas Limoncelli, StackOverflow.com, and Christina Hogan, AT&T Presented at: Usenix LISA 2016 https://www.usenix.org/conference/lisa16/conference-program

Recruiting HR IT Team
(a way to improve complex processes)
24 PunkRockDevops - December 8, 2016

59. New Employee Onboarding
• Process: Ad hoc. Improvised. Broken.
• Communication: Terrible. IT given no warning about arrivals.
• Trying New Things: Out of the question.
• Result:
• New employees unproductive for 4 weeks.
• First impression: I just joined a company of idiots.
• Everyone blames the IT department.
25 PunkRockDevops - December 8, 2016

60. New Employee Onboarding
• Process: Got agreement on a “onboarding timeline”.
Automated OS install/config for workstations.
• Communication: ID’ed process owner. Communication channels.
• Trying New Things: Google Sheets -> Trello -> Custom app.
Efficiency through alignment: Monday is Start Day.
• Improvements:
• New employees: Productive on day #1.
• First impression: Excellence/cooperation/efficiency.
• Less work for everyone involved!
• Opened the door to software to manage accounts, machines, etc.

Doing work in small batches
is better than big batches.
[Work. Check. Work. Check. Work. Check.]
is better than
[Work, work, work, Check.]

68. Big Batch Failovers
• The NY Datacenter fails less than once a year.
• In that time:
• “unintentional differences” accumulate.
• New SRE team members are hired
34 PunkRockDevops - December 8, 2016

69. The 2013 failover was a “big batch”
• Took 10+ hours (15 minutes user-visible down-time)
• Required “hands on” by 3 teams.
• Found 30+ “improvements needed”
• Certain people were S.P.O.F.
35 PunkRockDevops - December 8, 2016

70. Needed: “small batch” failovers
• More frequent failovers == smaller
accumulation of differences.
• So…. we Force Failovers Frequently to
achieve our “small batches”

• Each member of the team gains experience and builds confidence.
• Highlighted automation, documentation, and resource needs.
• Frequency reduces risk!
