4. Why DevOps

5. Agile Manifesto (2001)
We are uncovering better ways of developing software by doing it and
helping others do it. Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the
items on the left more.

6. Agile software development
• Highly visible
• Allows for greater adaptability
• Realise business value quickly
• Reduces risk
• Incremental and iterative delivery

19. Did it work?
• 2010
• Over 200 people involved in a
given release
• Live downtime required to release
software
• Release issues cause additional
downtime
• 2013
• One engineer needed to release
to production (takes ~30 mins)
• Down-time is a distant memory
• Release related incidents are
unheard of - rollback is easy if one
found

21. Key business benefits?
• We now focus our energies on building new features - not trying to
deliver them
• We now have a greater understanding of our platform
• We work together with aligned vision and goals
• “Us” and “then” all but eradicated

22. Some pointers, pitfalls and gotchas
• DevOps is not a silver bullet
• DevOps can help if you have a problem to solve
• Tooling (especially automation and CD tools) will help but is not the be
all and end all
• It's not an easy thing to implement and takes time, dedication, effort
and patience
• Some people may not want / be able to work this way
• Ensure you can measure progress and keep measuring - inspect and
adapt
• Get actively involved in the wider community, do some research and
reading
