 ## How did I get there?
 
 I attended Cloud Native Rejekts and KubeCon + CloudNativeCon Europe 2025 in London.
+This year I was sent there by my employer [DATEV eG](https://datev.de) - thanks again to everyone who helped me with getting this trip approved (you know who you are).
 
 Why? Because learning about all new things in the world of cloud is really important and war stories help to avoid mistakes that other's already made.
 And [last year's experience](https://kubecon24.nicolai-ort.com) was really good, so I wanted to go again.
 
-Plus I actually presented a talk at Cloud Native Rejekts.

+
+Premise: The CNCF landscape includes a huuuge number (80+) of security(related) projects.
+Analogy: Animal kingdom (includes simmilar-ish animals that might do some of the same stuff but not entirely the same)
+
+## Build Phase
+
+- How can i scan my container for vulnerabilities? -> Well you probably mean your image
+- The image itself is just a bunch of static layerns and we kinda have to trust the layers you didn't build yourself
+- The main tool used is still trivy with some easy steps
+  1. Extract layers
+  2. Build FS
+  3. Identify OS and Non-OS Packages
+  4. Compare with vuln-db
+- The animal in our analogy: Racoon
+
+## Deploy Phase
+
+- Kubernetes Native: Admission Controller
+- Tool used: Kyverno (integrates as an admission controller with yaml/crd based configuration)
+  1. Modify (e.g. add default resource limits)
+  2. Validate (check policies)
+- The animal is actually a human: The forrest guard
+
+## Start Phase
+
+- Before the pod itself is running CSI, CNI and secret related processes (the once we want to look into) happen
+- Problems: Secrets have no rotation or versioning mechanism, there is no default integration for external kms
+- Project: External Secrets -> Get secrets from external kms, automaticly sync (e.g. new versions)
+- The chosen animal: Capricorn
+
+## Run Phase
+
+- Goal: Runtime scannning without including specialized instrumentation in each application
+- Tool: Falco utilizing eBPF to check system calls against rules
+- Idea: Detect dangerous behaviour (e.g. check for someone trying to exploit a fresh CVE)
+- The analogy: Falcon
+
+## TL;DR
+
+1. Scan images (trivy)
+2. Enforce best pracices (kyverno)
+3. Use an external kms (external secrets)
+4. Scan at runtime (falco)

+
+## Featureflags?
+
+- Idea: Change the behaviour of an application without rebuilding it
+- Goal: Control rollout, reduce risk, experiment (a/b)
+- At google: A huge number of feature flags (150k+) but that's because people forget to turn them off
+
+## Where does the flag come from
+
+- Lifecycle of a flag: Create, Manage, Deprecate, Delete -> But will it be created frist in code or in the service
+- Classic implementation: Just a if/else that uses a function to get the flag
+- Problem: What if the flag names missmatch between the code and flag ser -> Muliple sources of truth
+- Solution: Require use of auto-generated flag bindings (codegen from the management system) to mitigate typos, etc.
+
+## OpenFeature
+
+- Goal: Vendor agnostic, standardized, open source
+- Basic setup: Register provider (once per app), create a client, use client to get flags
+- CLI: Integrate into management system, keep a local manifest of all flags and generate code (generates the client)
+- Now: Just call the client's method instead of hard-coding feature flag names

+Fair warning: This talk was very technical and pretty interesing - but don't even try to understand it if you're tired (or if it's the thrid to last session on the last day of a long conference).
+
+## Baseline
+
+- Standard example: Write and read KV-Data, `put(A,2) -> Get (A)`
+- Problem: Concurrency
+
+TODO: Steal image from intuition of correctness
+
+## Correctness
+
+- Correctness: Kinda funky when it comes to time
+- Fix: Define serialization that executes parallel request one after another to bring them in an order
+
+## Failures
+
+- What happens is connections between etcd nodes go down -> Serving stale data
+- What happens if data corrupts -> If enough members are online, it can repair itself
+- And many more that can happen at random times -> Hard to test
+
+TODO: Steal "in a concurrent world"
+
+## Robustness framework
+
+- Automates tests for failures
+- Includes reliable reproductions of past (seamingly random) errors
+- Currently a mixture of existing go debugging tools
+
+## Future
+
+- Reproduce more bugs consistently
+- Run additional consistency checks

 The last day of KubeCon - aka the day everone leaves early.
+But not me and I had no meetings scheduled for this day -> More talks for me and notes for you.
+
+This being my 7th day of the trip and 6th day of non-stop conferences took a bit of a toll on my note taking skills (expect more spelling mistakes).
