What exactly do you mean by “Dockerized node”? Can this node be on-premises or in the cloud?

A "Dockerized node" refers to any computing instance, such as a bare metal server, virtual machine (VM), or public cloud instance, that has the Docker Engine installed and running on it. This setup allows the node to run Docker containers, which are lightweight, portable units that package applications along with their dependencies, but not the entire operating system.

Yes, a Dockerized node can be on-premises or in the cloud. Docker is designed to be infrastructure-agnostic, meaning it can manage nodes that exist in your on-premises data center as well as those in virtual private clouds or public cloud providers like AWS, Azure, Digital Ocean, and others. This flexibility allows enterprises to deploy and manage their applications across various environments seamlessly[1][12].
