The set of core services on AWS remains amazing: EC2, S3, IAM, EKS, Route53, RDS etc.

AWS IAM is extremely well designed when you compare it with the spaghetti monster IAM systems of other clouds.

Every time I try the new cool thing supposed to replace these services on some other provider - I understand how mature and polished the AWS ones are.

With that said, the rest 90% of AWS services like WorkMail, Cognito, API Gateway, are absolute hot garbage which no good meaning AWS expert will touch with a 10 meter stick.
