In order to do some POCs over Mesos, Kubernetes, DC/OS and more, I would like to build a small cluster of 3-5 nodes. I started to build a cluster via AWS, but it becomes expansive fastly. So, I was wondering if there is a good way to build such a cluster without spending too much money on it.
There is a blog where the author gives a good explanation and open source code for a cheap 3 nodes HA production cluster. It's in Digitalocean but could be replicated in any similar host provider. It's too long to post everything here so check this link
