Real World DevOps

What works and what sure as hell doesn't

Mohan Krishnan / CTO @ KMKOnlineBBM, Vidio, Liputan6, Bintang, Bola

What isn’t “devops” ?● It is not a type of job● It is definitely not a department● It’s not just dev & ops - test &

security play a huge role

So, what is it?Value system: Working together across disciplines to faster feedback to achieve common business goals

How ?

● Skills● Process● Organisation● Tools

“Don’t EVER make the mistake that you can design something better than what you get from ruthless massively parallel trial-and-error with a feedback cycle.” — Linus Torvalds

Dont’s and Do’s

Opinionated, but based on experience

Don’t have production priests

● One group with the right to deploy to production

● Security and control○ Use tools and processes

not people

Don’t create silos

● Knowledge siloed in teams● Information siloed in tools● Security as a justification

to silo

Don’t have ops & dev working to different goals

How this happens ?

● Moral hazard: dev & test, ops & dev

● Reporting into different technical leads with different goals & objectives

● No shared definition of “done”

Do provide power, expect responsibility in return

● Ops: Platform tooling, self service systems, conventions

● Dev: Configuration, on-call, monitoring, deployments

“UNIX was not designed to stop its users from doing stupid things, as that would also stop them from doing clever things.”

— Doug Gwyn

Do constantly cross train

● Constant cross training between dev - ops - test

● How?○ Physical space○ Organisational values○ Information should be

default open

Do keep things simple

● Minimize configuration mgmt & orchestration○ Don’t go buzzword crazy

● Keep your application stack simple○ Standardise & keep them up to

date● Best ops is no ops

○ Automate, use managed services

“Simplicity is prerequisite for reliability” — Edsger W. Dijkstra
