Zfs, lxc, cgroups and so on, where can I read about all this in detail?

Question

ubuntu

In the job description for a junior engineer, I see the following description
Have an idea about the following technologies:

• zfs
  
• lxc
  
• cgroups
  
• apparmor
  

I understand that the list is not complete, but all these things are from some kind of general opera. Please advise the literature that would give me a general idea about these and other technologies, obviously related to them. Of course, I spree each one individually, but there is no picture in my head ...
Thanks in advance.
