Every Digital Moment matters!
Klaus Enzenhofer @kenzenhofer
A Saturday on a scouting
trip!
What has all of this to do with us here?!
2011“In Short,
Software is eating the
world!”https://en.wikipedia.org/wiki/Marc_Andreessen
Largest companies in the world by Market Cap

The „I get paid at the end of th
e month“- dashboard
Are we making money?
99.9% Availability
End-User Satisfaction
End-User Satisfaction
Key Transaction – Errors, Response Time and Usage
Competition
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
