We tried three different combinations to create a Swarm cluster in AWS. We used Docker Machine with the AWS CLI, Docker for AWS with a CloudFormation template, and Packer with Terraform. That is, by no means, the final list of the tools we can use. The time is limited, and I promised myself that this book will be shorter than War and Peace so I had to draw the line somewhere. Those three combinations are, in my opinion, the best candidates as your tools of choice. Even if you do choose something else, this chapter, hopefully, gave you an insight into the direction you might want to take.
Most likely you won't use all three combinations so the million dollar question is which one should it be?
Only you can answer that question. Now you have the practical experience that should be combined with the knowledge of what you want to accomplish. Each use case is different, and no combination would be the best fit for everyone.
Nevertheless...
