SYS · Systems administration

Run Linux systems, networks and storage like they matter. They do.

For people entering systems administration and for administrators moving to automation, virtualisation and hybrid cloud. Everything is done on real machines first, then automated.

who

Who this track is for

  • IT support and helpdesk staff moving to server administration
  • Windows administrators adding Linux
  • Administrators who run everything by hand and need automation
  • Small-company IT generalists responsible for servers, networks and backups
levels

Three entry levels

Profiling places you on one. The cohort is built from people on the same level with the same target, so the plan is never too slow for half the room.

  1. level 1

    Entry

    you are
    You use Linux a little and support users, but have not built and run servers yourself.
    you get
    You build, secure, back up and monitor Linux servers and a small network, and document it so someone else can run it.
  2. level 2

    Sysadmin

    you are
    You run servers already and want to stop doing things by hand.
    you get
    Infrastructure automated with Ansible, virtualised, monitored, with tested backups and change control.
  3. level 3

    Senior / infrastructure engineer

    you are
    You own the whole environment and are moving it toward hybrid cloud.
    you get
    Design, capacity, hybrid cloud, cost, security baseline and the on-call for all of it.

tools

Tools you will work with

  • Debian / Ubuntu
  • RHEL family
  • Bash
  • Python
  • nftables
  • WireGuard
  • Proxmox
  • KVM
  • LXC
  • Docker
  • nginx
  • PostgreSQL

The final list is set in the cohort plan. Where the market is split, such as cloud providers, the cohort picks the one most of its members need.

outcomes

By the end, you can

  1. Build a hardened Linux server and a small network from scratch, documented
  2. Automate it with Ansible and rebuild it from code on demand
  3. Prove your backups by restoring them in front of the cohort
  4. Monitor, patch and run the environment through a simulated on-call week
example

Nine people, Linux from the ground up, 12 weeks

Six helpdesk engineers and three Windows administrators. The plan spent two extra weeks on Linux fundamentals compared to the standard outline and added a Windows-to-Linux translation session in week one.
