- Artifact Repositories: Nexus and ArtifactoryWhy you need a private artifact repo, hosted/proxy/group repository types, caching public registries, retention and cleanup, promotion between repos, and auth for CI.
- Chaos Engineering BasicsThe steady-state hypothesis, blast-radius control, common experiments (pod/node kill, latency, packet loss, dependency failure), tools, running a game day, and turning findings into fixes.
