This book explores the practices and tools required to run a Swarm cluster. We'll go beyond
a simple deployment. We'll explore how to create a Continuous Deployment process. We'll
set up multiple clusters. One will be dedicated to testing and the other for production. We'll
see how to accomplish zero-downtime deployments, what to do in case of a failover, how to
run services at scale, how to monitor the systems, and how to make it heal itself. We'll
explore the processes that will allow us to run the clusters on a laptop (for demo purposes)
as well as on different providers. I'll try to cover as many different hosting solutions as
possible. However, time and space are limited, and the one you use (be it public or onpremise)
might not be one of them. Fear not! The processes, the tools, and the practices can
be easily applied to almost any. As always, this book is very hands-on oriented, but the goal
is not to master a particular set of tools but to learn the logic behind them so that you can
apply it to your job no matter whether your choice ends up being different.
