AWS - EKS

Kubernetes

- Kubernetes is cloud-agnostic (can be used in any cloud – Azure, GCP…)
Amazon EKS
- Amazon Elastic Kubernetes Service
- a way to launch managed Kubernetes clusters on AWS
- an alternative to ECS, similar goal but different API
- supports
  - EC2 if you want to deploy worker nodes
  - Fargate to deploy serverless containers
For multiple regions, deploy one EKS cluster per region
Collect logs and metrics using CloudWatch Container Insights
Use case:
- if your company is already using Kubernetes on-premises or in another cloud, and wants to migrate to AWS using Kubernetes

Managed Node Groups
- Creates and manages Nodes (EC2 instances) for you
- Nodes are part of an ASG managed by EKS
- Supports On-Demand or Spot Instances
Self-Managed Nodes
- Nodes created by you and registered to the EKS cluster and managed by an ASG
- You can use prebuilt AMI - Amazon EKS Optimized AMI
- Supports On-Demand or Spot Instances
AWS Fargate
- No maintenance required; no nodes managed
Sample:
- Amazon EKS supports the following node types, EXCEPT ………………..
- Lambda.

Need to specify StorageClass manifest on your EKS cluster
Leverages a Container Storage Interface (CSI) compliant driver
Support for…常考
- Amazon EBS
- Amazon EFS (only works with Fargate)
