Hi, I&#x27;m the founder of Docker. Sorry that you had an issue on the website. I warned the team of your comment, feel free to email me directly at s@docker.com and I&#x27;ll put you in touch.<p>Note that the price you mention is yearly. A node is anything you can install Docker Engine on. Typically it&#x27;s a physical or virtual server. All nodes are combined into a swarm, which you can manage from the control plane.
