What has all of this to do with us here?!

Are we making money?

This is all Ops!Where is the Dev?!

700 deployments / YEAR

10 + deployments / DAY

50 – 60 deployments / DAY

Every 11.6 SECONDS

Deliver value at the speed of business

Richard DominguezDeveloper in OperationsPrep Sportswear

„In 2013 business demanded to go from monthly to daily deployments“

„80% failed!“

Why they (and many others) failed!

26.7s Load Time5kB Payload

33! Service Calls

99kB - 3kB for each call!

171! Total SQL Count

Architecture ViolationDirect access to DB from frontend service

Single search query end-to-end

The fixed end-to-end use case“Re-architect” vs. “Migrate” to Service-Orientation

2.5s (vs 26.7) 5kB Payload

1! (vs 33!) Service Call

5kB (vs 99) Payload!

3! (vs 177) Total SQL Count

It‘s not about blindly giving everyone Ops powerto deploy changes only tested locally

It‘s not about blind automation of pushing more bad code on new stacks through a pipeline

You measure it! from Dev (to) Ops
