Clusters & cloud
Running a cluster for real
A cluster that only runs on your laptop isn't a cluster yet. These pages cover what changes when it has to survive traffic, a node dying at 3am, and a finance team asking about the bill.
Managed Kubernetes
What EKS, GKE, and AKS actually run for you, and what's still yours.
Autoscaling
Scaling Pods with the HPA and nodes with the cluster autoscaler.
Cluster networking & CNI
How Pod-to-Pod traffic actually moves, and how to restrict it.
Storage in the cloud
CSI drivers, disk types, and access modes across providers.
Service mesh
What a mesh adds on top of Services, and when it's worth the cost.
CI/CD for containers
Building, scanning, and shipping images from commit to cluster.
Cost optimization
Where cluster spend actually goes, and the highest-leverage fixes.
