- Welcome to lesson three.
In this lesson, we'll explore
some of the advanced Systemd features.
I'll start talking about Systemd units in general,
and after that you'll learn about Systemd sockets
and timers.
Next, I'll introduce the topics of Systemd Cgroups,
something you can use to limit the availability of resources
to different services that are started through Systemd.
After this, you'll learn how to manage
Systemd unit dependencies.
The last lesson in this module covers Systemd self-healing.
A useful feature that ensures that after a failure
a unit can automatically be started again.
This lesson ends with the lab,
which helps you practice the topics just learned.
