The tutorials from the Linode crowd are just spot on. This video cleared up my time concerns! Thanks again

This video is a savior. I am now learning Docker and DevOps and still have no idea how on Earth does Docker looks like in an actual deployment on the webserver (because I only have experience in deploying a Node.js app on a Linode via SSH). Linode tutorials never fail me.

One question about the future of Linux. If IBM now owns red hat and no longer supports the Linux community ... and Linux has become so large and requires high level management support to protect the operating system against vulnerabilities, does anyone think Linux will survive or be around as a serious option as an open source OS in the near future? Anyone have any insight? Will Linode be the future of Linux?

There seems to be some confusing information here. Early in the video you said that a container contains the app, it's dependencies and the OS. Then later you said that the containers all share the host OS. Which one of those statements is true?

Also, if the latter is true and the containers all share the host OS, does that mean architecture specific apps would need to be run on hosts running the corresponding OS? For example, if you build an app for Windows (let's say in C++) and build a container image of that app, can you run that container and app on a Linux host?

Also, I've never seen a VM take minutes to start up. Even the heaviest VMs I've ever worked with (databases) only took seconds to start up. Not sure where "minutes" comes from.
