2. Apigee
apps
data ( big! )

is not (just) about
titles ( let’s debate this later )

The significant problems we face cannot be solved
at the same level of thinking we were at
when we created them.

will solve your problems ?
may not => without a few paradigm shifts

TDD (Test Driven Development)
BDD (Behaviour Driven Development)
CDD (Customer Driven Development)
&
?

9. ODD ( Operations Driven Development )
optimize for your biggest customer
ops/support team

10. ODD: how to begin?
very early ops engagement ( day 1 )
architect/code with operations in mind

11. ODD: debuggable?
loglevel = empathy
debuglevel = service level agreement

12. ODD: silent?
no silent deaths
no silent waiting

13. ODD: metrics & counters
show the traffic

14. ODD: app level tracing
show the inner self

15. ODD: easy to deploy?
rpm vs. tar
config files vs. hardcoding

16. ODD: dns to db
/etc/hosts vs. dns
new nosql db vs. reliable sql db
experiment but is it production ready yet?

17. Beyond
Engineering
( just )
the product

18. ‘Engineering’
the infrastructure
tuning - ( i/o | cpu | memory ) bound
scalable?
benchmark
architect for cost saving

19. ‘Engineering’ the tools
same importance as the product development?
full time job ?
hire full time developer ? ( and follow ODD )
