    If any user figures out how to run your app without trickle your bandwidth management no longer works. You need method that are part of the kernel for proper bandwidth management.

    • @cybernard,
      Would you be as kind as to share a specific example of how an user would be able to do that? Please notice that we covered this possibility near the bottom of the article. If you make an experiment and are able to fool trickle, please report back with the specifics so we can edit the article accordingly. Thank you!

    This is very interesting but a bit redundant. Cgroups (control groups) is built into the kernel and provides awesome control over an application’s usage of not only network but mem, CPU, disk I/o and more. This is taken to the next level by containers and docker which provide better tooling and automation to make more easily use cgroups and other plumbing built into the os.
    I highly recommend spending your time learning docker and the other container tooling as this is the future for better designed apps and this skill set is in VERY high demand right now.

    • @Terry,
      Thanks for taking the time to share such a well-supported and informative comment. You are SO right about docker. The reason why we published this article is because it outlines the basics of network bandwidth shaping. We will consider writing and publishing a docker series in the near future once we’re done with the RHCSA and RHCE series.
