One of the core feature of any Linux system is that they are built for automation. If a task may need to be executed more than one time - even with some part of it changing on next run - a sysadmin is provided with countless tools to automate it, from simple shell scripts run by hand on demand (thus eliminating typo errors, or only save some keyboard hits) to complex scripted systems where tasks run from cron at a specified time, interacting with each other, working with the result of another script, maybe controlled by a central management system etc.

The term "containers" is heavily overused. Also, depending on the context, it can mean different things to different people. Traditional Linux containers are really just ordinary processes on a Linux system. These groups of processes are isolated from other groups of processes using resource constraints (control groups [cgroups]), Linux security constraints (Unix permissions, capabilities, SELinux, AppArmor, seccomp, etc.), and namespaces (PID, network, mount, etc.)
