EKS bookmarks

AWS EKS is not simple to install and maintain.

• what is the best way to install ( cloudformation, eksctl , AWS CDK , Terraform or maybe using Cluster API ?)
• which infrastructure applications are needed on top of eks ? ( alb , external dns , node drainer etc)
• what are the integrations to other AWS services ? ( OIDC , cloudwatch , elasticseatch etc )
• how you should upgrade - blue greeen ? rolling upgrade ? or maybe red black ?

I will try to address these questions in the future . for now, lets start with my EKS bookmarks
