Kubernetes operations (kops) compared to Docker for AWS

Docker for AWS (D4AWS) quickly became the preferable way to create a Docker Swarm cluster in AWS (and Azure). Similarly, kops is the most commonly used tool to create Kubernetes clusters in AWS. At least, at the time of this writing.

The result, with both tools, is more or less the same. Both create Security Groups, VPCs, Auto-Scaling Groups, Elastic Load Balancers, and everything else a cluster needs. In both cases, Auto-Scaling Groups are in charge of creating EC2 instances. Both rely on external storage to keep the state of the cluster (kops in S3 and D4AWS in DynamoDB). In both cases, EC2 instances brought to life by Auto-Scaling Groups know how to run system-level services and join ...
