Up until now, we showcased the features of AWS and GCP and introduced some other providers that are very interesting choices when building our systems. One of the advantages of having a good number of competitors in the market is the fact that each one of them has their own strong points and we can combine them by making use of VPNs, creating a big and extended virtual data center across different providers.
Through the rest of the book, we are going to give special attention to AWS and GCP, as they have the most interesting characteristics for a DevOps book (not to overlook the rest of them, but remember, things are limited in terms of space).
We are also going to take a special interest in container clusters such as Kubernetes or Docker Swarm as they are, without any kind of doubt, the future.
