i’m 38 years old . Due to recent on going retrenchment i’m looking for career switch from ITSM to Linux system admin or Linux Support.
I took Linux RHCSA certification and DevOps course where the course cover
Docker
Jenkins
Terraform
Ansible
AWS
Kurbenetes
I’m still unable to get into the tech industry as lack of experience and interview are asking for real life scenario question. The rhcsa certification is more to linux foundation where it cover admin job
can some one please give me real situation that we might face as Linux Support or System Admin and where can i gain the experience in terms of troubleshooting.
Welcome to the forum!
Given your name, I’d think you’re probably from India. That is going to be a really tough market to get into for you. If by “ITSM” you mean moving from a company like Tata, Infosys, Accenture and others, from a help desk / OPS monitoring job over into Linux, that’s going to be even more of a hard sell. I wish you the best of luck.
When I was getting started I kinda fell in the same trap. Deploying software isn’t the same as running and maintaining software. Knowing how to deploy docker, k8s, ansible, terraform and others isn’t the same as running, tweaking and maintaining them.
It’s gonna be hard for someone to reproduce the issues in the wild in a homelab. Can you figure out what happens when a spike of 1000 users try to hit your website in 1 minute? Can you tweak your website to auto scale? One of your admins reused a password present in a data leak and a hacker gained access to his account and is monitoring the infrastructure and poking around without causing a disturbance yet. Are you aware of that? You have a production database that just crashed and corrupted the DB. Can you bring it back up?
There’s a ton to learn from deploying software, but most companies will want you to not only know the basics of linux and software deployment, but will want experience in dealing with running the software for many users for a prolonged period of time. That’s not something you gain from a homelab, unfortunately.
If it was me, I’d first look at your enthusiasm, base knowledge level and try to assess your potential. But that’s not what most people do. They want experience and they don’t want to spend too much time training you.
Look for a company that is willing to train their new staff. If you already have a good base and you know to look in /var/log/messages, dmesg, manage systemd and all the other plain basics, then you should have a fairly easy time going in.
