> Adding an entirely new instance is not the only way to accomplish each of those things. A lot of those things can be treated just like applications. That's what containers are. Containers are applications, packaged to be easily deployable and ran as contained processes. That's it. Kubernetes is just a tool to run containers in a cluster of COTS hardware/VMs. I've said it once and will say it again: the testament of Kubernetes is simplify so much the problem of deploying and managing applications in clusters of heterogeneous hardware communicating through software-defined networks thay it enable clueless people to form mental models of how the system operates that are so simple that they actually believe the problem is trivial to solve.
