Latest release of Docker project integrate a Swarm mode to manage your cluster environment. The idea of this post is to show how to use Docker Swarm to deploy an ElasticSearch 5.0 cluster, to be similar to a production DataCenter I am using docker-machine to deploy six nodes of my Swarm cluster, similar deployment could be replicated in a public cloud such as AWS or DigitalOcean by simple change a parameter in docker-machine create command.

Although the new Raspberry PI has almost the same hardware under the hood, I just couldn’t resist to compare it with its predecessor on the test bench.
As expected, the outcome of the tests doesn’t show a performance difference between the old and the new version…. but although there is no difference in performance, power consumption is another story. During benchmarking, the Pi’s were connected to a bench top power supply to monitor their power consumption. This is the result.
