Module 7
Real-world EKS
Put everything together: Shopwave's EKS landing zone, the Cluster Autoscaler to Karpenter migration, how EKS compares with GKE, and three incidents that each trace to one mechanism.
Why it matters. Architecture diagrams show the happy path. Incidents and migrations show where the design is thin. Reading them is the fastest way to learn what to harden first.
After this module you can answer
- What does a sensible EKS landing zone contain?
- How do I migrate to Karpenter without downtime?
- EKS or GKE: what actually differs day to day?
- How do failures map back to the mechanisms I learned?
