DevEx | GitOps & ArgoCD
Micro FeedBack Loops

DevEx
A Cloud-Native

3.
why?

4.
Shifting Architecture(s)

5.
We tend to take
our work very
seriously

6.
Faster!, Higher!,
Stronger!
- More features
- Time To Market
- When Is it ready ?

7.
PUT IMAGE HERE
AND CROP AS CIRCLE
Operational Overhead
- The TCO & ROI of the entire
SDLC - is defined by its
operational cost
- More CapEx - Capital (Capability)
exp
- Less OpEx - Operational exp

what

9.
Developer to “yak shaver”
Some days … more than others

10.
Developer to “yak shaver”
Many TOIL’s
along the road
…

11.
how

12.
Transform
Frustration to
Motivation ?

Much more than just Git !

Build your platform - PRODUCT THINKING
What kind of environment would you like want to work in ?
- Interfaces UI / CLI
- Logins
- Context switches …

16.
Build your platform - Remote |
Offline

17.
Shorter ! Feedback Loops
DOD - Definition of Done
- How do I know it’s done ?
- How does the team know it’s done ?
- How does management know it’s done ?
- How does NOC know it’s functional ?

18.
- Revisit -> Re Target your CI / CD processes
- Chosen Frameworks
- Educate your teams / selfs

19.
Solution Suggestion
that works
But …

20.
Reduce Frustration | Micro Feedback loops ++
● Helper-tools / Utilities
● Make (my personal favorite)
● Kubectx / kubens
● Common functions
○ Set cloud provider project / profile
○ Get a secret from credentials store
● IDE -plugins
● IDE - the obvious
○ Auto lint / build / deploy

21.
Developer Self-Service
Cloud Native | like ordering on amazon …

22.
Self-Service Cloud Resources
cpu, ram, [ disk, network ]

23.
Self-Service Kubernetes Resources
cpu, ram, [ disk, network ]

24.
- selfService CI

25.
Demo that (should) works
How will our Dev
Experience look
like with GitOps ?

26.
If you're seeing this
slide the demo
failed miserably ;)

27.
🚀 Boosting the Developer
Experience
Crawl, Walk, Run, Fly !

28.
Shorten them feedbacks !
- Not just standard pipelines
- DAG’s
- Logic which speeds up the feedback loop
- Caches
- …
- Flows based on Git Operations
