Some questions, want to sent to you to discuss: in my understanding is as follows: first of all in ali cloud platform (made up of different physical nodes) - use ali cloud platforms provide the ESC (that is, the tenants now use redhat or other instances) - to build on this instance docker (now is like this? So, is understood as, a virtual instance on a physical machine in the building the docker? Use the docker to create a different container (redhat or other to host applications)? So why not directly docker, on a physical machine in the docker bearing applications?
That is, Mode 1: physical machine - instance - docker (container) Model 2: physical machine - docker (container)
So mode 2, there is necessary to virtual instances come out from the physical machine? So what is the role of cloud here?
