What is this?
Kubernetes on AWS typically means EKS for the control plane plus managed node groups, add-ons, and IAM Roles for Service Accounts.
Why should you care?
AwsVerse multi-tenant SaaS uses EKS with namespace isolation and network policies per customer tier.
See it live — copy this example
Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).
eksctl create nodegroup \
--cluster awsverse-prod \
--name ng-general \
--node-type t3.medium \
--nodes 2 --nodes-min 1 --nodes-max 4 \
--managedWhat happened?
- eksctl creates a managed node group autoscaling between 1 and 4 nodes.
- Pods schedule on these workers unless using Fargate profiles.
Practice next
- Install eksctl and kubectl.
- Create cluster or use existing.
- Deploy sample app: kubectl apply -f deployment.yaml.
- Install AWS Load Balancer Controller add-on.
- Create Fargate profile for kube-system namespace.
Remember
EKS = managed k8s on AWS. Use IRSA for AWS API access. Managed node groups simplify patching.
AwsVerse tenant isolation
Each SaaS tier runs in separate namespace.
Outcome: NetworkPolicy plus IRSA prevents cross-tenant S3 access.
