Paradigm shiftThe significant problems we face cannot be solved

at the same level of thinking we were at

when we created them.

- Albert Einstein

Devops team

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

‘X’ driven development

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

ODD ( Operations Driven Development )

optimize for your biggest customer ops/support team

ODD: how to begin?

very early ops engagement ( day 1 )architect/code with operations in mind

ODD: debuggable?

loglevel = empathydebuglevel = service level agreement

ODD: silent?

no silent deathsno silent waiting

ODD: metrics & counters

show the traffic

ODD: app level tracing

show the inner self

ODD: easy to deploy?

rpm vs. tarconfig files vs. hardcoding

ODD: dns to db

/etc/hosts vs. dnsnew nosql db vs. reliable sql dbexperiment but is it production ready yet?

Beyond Engineering ( just ) the product

‘Engineering’ the infrastructure

tuning - ( i/o | cpu | memory ) boundscalable?benchmarkarchitect for cost saving

‘Engineering’ the tools

same importance as the product development?full time job ?hire full time developer ? ( and follow ODD )
